Each volute shall have smooth fluid passages, I-1 large enough at all points to pass any size solid which can pass through the impeller, and provide smooth unobstructed flow. A large clean-out open- ing with removable cover, having its interior surface matching the volute contour, shall be located on each casing at the impeller centerline, to allow access to interior of the impeller. Each casing shall be split per- pendicular to the shaft, with removable suction cover and stuffing box cover. Each casing shall be so arranged that the impeller may be removed without disturbing either suction or discharge piping. Suction and discharge connections shall be ASA 125-pound flat face flanges. All flange bolt holes shall be slotted for ease of assembly and disassembly. Each suction and discharge flange shall be drilled and tapped for gauge connections. A plugged 1/4-inch IPS tap shall be supplied in the suction nozzle, and a 1/4-inch IPS tap in the discharge nozzle.

Each impeller shall be of the single-suction enclosed type with two vanes, made of close-grained cast iron. Each impeller shall be particularly designed with smooth water passages to prevent clogging by stringy or fibrous materials, and shall be capable of passing solids having a maximum sphere size of 6 and 4 inches at Boggs Creek Pumping Station and Chestnut Street Pumping Station, respectively. Each impeller shall be statically and hydraulically balanced. Each impeller shall be attached to the shaft in a manner that reverse rotation will not damage the impeller or shaft. The rotation shall be as shown on the Plans. A double mechanical seal assembled in a cast.-iron stuffing box shall be furnished. ' The mechanical seal shall be similar or equal to Crane Pack- ing Company Type 21 with ceramic rotating faces, carbon stationary faces, stainless steel springs, and synthetic rubber bellows. One spare seal shall be furnished for each pumping station. The assembly shall be so de- signed as to be easily removed from the shaft as a unit. The seal shall be lubricated and pressurized by water bypassed from the pump discharge nozzle, through a filter, into the mechanical seal as shown on the Plans. The filter shall be made of corrosion-resistant material, and shall be capable of screening out all solid particles larger ® than 20 microns. The filter shall be similar or equal to Model A-1/4 K- Master Kleen Air Filter with Grade C fine element as manufactured by Kaye & MacDonald, Inc.

Payment for all work performed on the premises of the Railroad shall be paid at the applicable lump sum or unit prices bid for the various items of construction. 5. INTERFERENCE WITH TRAFFIC: It must be recognized that in some instances the work of this project involves the construction of sewers along the public streets of the developed municipality. Access to abutting property should be provided wherever it is possible without interference with the construction opera- tion. The Contractor will be required to provide satisfactory bridges to allow traffic to cross over the excavated trench where the street intersec- tion is traversed by open cut excavation. Care should be taken to avoid blocking of access to fire hydrants during this construction. After the sewer is constructed and the backfill made over the completed sewer, a temporary pavement is to be laid down and the street open to traffic in order to provide access to abutting property as soon as possible. Open cut crossings are to be maintained for 60 days with macadam or other sat- isfactory material so as to provide an all-weather roadway surface, after which time the restoration of the permanent pavement of the type ordered by the Engineer shall be carried out. Payment for all work described in this paragraph shall be included in the unit price bid for "Class B Trench Excavation". 111-4 6. PROTECTION OF TREES AND RESTORATION OF LANDSCAPED AREAS: Wherever the sewer is to be built in a right-of-way located along occupied property which has been landscaped or in the sidewalk space ad- jacent to trees, and wherever trees are encountered adjacent to the line of the work, the Contractor's operations must be so organized and carried out as not to disturb or destroy any trees except where permission to do so has been obtained from the property owners with the Engineer's approval. The existing surface shall not be disturbed beyond the limits of the right- of-way, which shall include the necessary area for storing of materials of construction and excavated materials. Upon completion of the work, the surface shall be replaced to conform to the original surface. Where turf has been disturbed, the completed backfilled surface shall be sodded or raked and seeded during the proper time of the year. Where excavated material is stored adjacent to trees, it shall be carried away so as not to cause injury to them in any way. 'If necessary, boxing shall be provided around trees, plants or shrubs. Upon completion of the work, such box- ing shall be removed and the original condition restored. Payment for carrying out the necessary protection and restoration of trees and land- scaped areas, as herein specified, shall be included in the payments made at the price bid per cubic yard for "Class B Trench Excavation". Where excavation is made through surface rock, the Contractor may be required to restore the surface to its original contour. The Contractor will replace the surface rock with Class C concrete at the direction of the Engineer. Such concrete will be measured and paid for at the price bid per cubic yard for "Class C Concrete". 7. PROTECTION OF EXISTING STRUCTURES: The work must be carried out in such a manner that all structures or improvements along and adjacent to the new sewer construction are properly protected. Any damage occurring to property of others because of the Contractor's operation shall be repaired to the satisfaction of the owner of said private property by the Contractor and the cost considered as covered in the item of "Class B Trench Excavation". 8. PROTECTION OF POLE LINES, WATER AND GAS PIPES, AND ALL OTHER UNDERGROUND UTILITIES: ® On the Plans, for the work to be constructed under this Contract, is shown the record information which has been obtained from the utilities for underground pipes or conduits which exist along the line of the proposed HI-5 sewers or at the location of the other improvements. The City does not guarantee the accuracy of these locations, but merely indicates the infor- mation which has been obtained from the companies owning such under- ground pipes or conduits. The locations of utility poles, shown as noted at the time of the survey, may have since been changed. It is assumed that the Contractor will make a field inspection of the locations of the work, and note all poles and overhead improvements which may affect his method of operation in the construction of the sewers and other im- provements at such locations. Such poles, overhead wires, underground pipes and conduits that may exist or maybe encountered are to be protected at the Contractor's expense. Any expense or inconvenience caused by their existence, and the necessary protection during the construction of the sewers or other facilities adjacent thereto, shall be considered as covered and included in the price bid for "Class B Trench Excavation", or the lump sum bid for other improvements. The Contractor shall notify the utility owners in advance of any construction which would expose underground pipelines or otherwise affect their safety. 9. REMOVAL AND REPLACEMENT OF SECONDARY PAVEME14TS: �1 Secondary pavements, consisting largely of crushed rock and cinders, which are to be removed in the course of the construction, shall be replaced with a layer of crushed rock compacted to a minimum thick- ness of 8 inches. The road surface shall be maintained for a period of go 60 days after initial replacement to allow for settlement and consolidation of the backfill, after which it shall be bladed to a smooth and uniform surface. No separate payment for the removal and restoration of secondary pavements shall be made. Payment for such removal and replacement shall be considered as included in the price bid for "Class B Trench Excavation". 10. REMOVAL AND RESTORATION OF ASPHALTIC PAVEMENT: The asphaltic pavement to be removed shall be cut. to neat straight lines. After completion of the granular backfill, a layer of crushed rock shall be compacted to a minimum thickness of 8 inches. The rock course shall be primed and covered with a minimum of 2 inches of asphaltic con- ' crete wearing surface to the cross section and grade as set by the Engineer to meet the present undisturbed pavement on each side of the area restored. Asphaltic concrete and placing methods used shall be similar in quality to 111-6 i the original pavement and approved by the Engineer. The Contractor shall restore the surface to the grade specified by the Engineer, should any settlement take place within 1 year of the initial pavement restoration. Payment for the removal and restoration of asphaltic concrete shall be limited to an area calculated on a width equal to the trench payline widths herein specified for the particular size of sewer installed, multi- plied by the length of pavement restored. Payment will be made at the price bid per square yard for "Restoration of Asphaltic Pavement", which payment shall include the whole cost of removing the existing pavement within cut straight lines, disposing of the material removed from the line of work, preparing the subgrade, furnishing of plant, labor, materials, tools and all other incidentals which may be necessary for removing and restoring the pavement. 11. REMOVAL AND RESTORATION OF CONCRETE CURB: Where the alignment of the sewers requires the removal of existing concrete curb, removal shall be to the full width of the concrete pavement removal. The curb shall be cut in a neat straight line and shall be replaced an to the same cross section as that removed,using Class A concrete. Payment for the removal and restoration of concrete curb will be made at the price bid per lineal foot for "Restoration of Concrete Curb", which payment shall include the whole cost of removing the curb and laying the new sections as required. Curb paralleling the sewer trench will not be measured or paid for unless it falls within a distance equal to one-half the payline width of the trench involved. 12. SIDEWALKS AND DRIVEWAYS: Where sidewalks or driveways are removed, the Contractor shall replace them with materials similar to those removed and to the reason- able satisfaction of the owner. No separate payment for the removal and restoration of sidewalks and driveways shall be made. Payment for such removal and replacement shall be considered as included in the price bid for "Class B Trench Excavation. " 13. EXCAVATION - GENERAL: All excavation shall be carried out accurately to the line and grade as shown on the Plans and as established by the Engineer. 111-7 If the bottom of the excavation is found to be unstable or to include ashes, cinders, refuse, vegetable or other organic materials considered unsuitable by the Engineer, the Contractor shall excavate and remove such unsuitable material to the depth required and backfill to the original sub- grade with granular backfill, well-compacted by means of mechanical tampers or vibrators in 6-inch layers, except as noted hereinafter. If over-excavation is required by the Engineer, the Contractor shall be paid for the over-excavation and backfilling of same at the unit cost per cubic yard for the various types of excavation agreed to in the Contract. Any unauthorized over-excavation shall also be backfilled as described above but no payment shall be made for such over-excavation and backfilling. Where necessary to protect labor, the work or adjacent property and in all trenches deeper than 6 feet, the Contractor shall provide and install shoring. Such shoring shall remain in place until the backfill has proceeded to a point where it can be safely removed, except that if in the opinion of the Engineer, damage is likely to result from withdrawing shor- ing, it shall remain in place. as All excavation shall be dewatered before any construction is under- MR taken therein. Concrete shall be placed only upon dry firm foundation material and pipe shall be laid only in dry trenches. The responsibility of the Contractor with respect to the use of ex- plosives in blasting includes compliance with all laws, rules and regula- tions of the State, the City and the insuror, governing the.keeping, storage, use, manufacture, sale, handling, transportation or other distribution of explosives. All. operations involving the handling, storage and use of ex- plosives shall be conducted with every precaution by trained, reliable men under satisfactory supervision. Blasts shall not be fired until all persons in the vicinity have had ample notice and have reached positions out of danger therefrom. The Contractor shall advise the Engineer in advance when charges are to be set off. After a blast is fired, the Contractor shall thoroughly scale the excavation, removing all loose and shattered rock or other loose material which may be dangerous to the workmen,, and the excavation shall be made safe before proceeding with the work. The fact that the removal of loose or shattered material may enlarge the excavation beyond the required limits shall not relieve the Contractor from the necessity for making such ® removal, and the Contractor shall not be entitled to compensation therefor. Payment for excavation shall be as described in the following para- graphs on "Trench Excavation" and "Structural. Excavation". III-8 14. TRENCH EXCAVATION: The work included under "Trench Excavation" shall comprise any necessary clearing of the .line on which the sewer, force main, water line, or other conduit is to be constructed; of making all excavations of all mate- rials of every description which may be encountered and as classified hereinafter as "Trench Excavation, Class All and "Trench Excavation, Class B"; of furnishing and placing of all shoring, sheeting and bracing which may be necessary to protect the work and to execute it; of shaping the bottom; of furnishing all equipment which may be necessary to keep the trenches 'free from water so that the sewers, force mains, or other conduits, and concrete may be placed in the dry; of providing for the un- interrupted flow of surface water or sewage adjacent to the line of the work during the progress of the work so as not to interfere with the natural surface flows; of protecting all pipes, conduits, culverts, bridges and all other public and private property which may be endangered by the work; and of hauling away all surplus excavated material. A series of borings was taken along the entire length of the con- struction. The results of these borings are shown on the Plans for infor- mation only. There is no expressed or implied agreement or guarantee that the depths or character of materials are correctly shown or that conditions affecting the work will not differ from those shown on the Plans. All excavation shall be dewatered to the satisfaction of the Engineer before any construction is undertaken therein. 1 Class A material is any material, such as solid limestone or hard stone in original bed or well-defined ledges, large boulders, detached pieces of limestone or hard stone, or mass concrete more than 9 cubic feet in volume, any of which cannot be removed by heavy equipment without drilling and blasting or wedging. Where rock or other hard material occurs in the trench so that any portion of the pipe would rest on rock or hard material, or at the direction of the Engineer, the trench excavation shall be carried to a depth below the planned grade so that no rock is closer than 2 inches to the outside of the pipe at any point. The width of trenches shall ti..e ample to permit the pipe to be laid, jointed, and covered properly. Class B material is any material not included in Class A excavation. Trenches shall be dug so that all pipes can be laid to the alignment and depth required. The width of trenches shall be ample to permit the pipe III-9 to be laid and jointed properly and the backfill to be placed and compacted. Additional width shall be provided where shoring or bracing is used. In order to avoid superimposed loading in excess of the designed and specified pipe strength and to provide sufficient room for proper in- stallation and bedding of pipe, the trench widths for the sewer pipe sizes used shall be kept within the limits specified as follows: Size of Pipe Minimum Width Maximum Width 8" - 1211 21-411 21-1011 15" 21-811 31-211 18" 2'-1'1," 3'-6" 21" 3'-3" 3'-10" 24" 31-611 41-011 27" 31-911 41-411 30" 4'-1" 4'-8" 36" 41-811 51-011 The Contractor may, at his option, where working conditions and rights-of-way permit, and with the approval of the Engineer, excavate sewer trenches with sloping sides, but with the following limitations: Only braced vertical trenches will be permitted in streets, alleys or easements which are paved, or in locations where the trenches are in close proximity to utilities, buildings, railroad tracks, or other installa- tions which could be endangered by the excavation. Where trenches are excavated with sloping sides for pipe sewers to be installed, the slope shall not extend below a point one foot above the extrados of the pipe, and the trench excavation below the point shall be carried out with vertical sides for widths not exceeding the maximum widths provided for in these specifications above. Piny trench excavated with sloping sides for pipe sewers which has ta width one foot above the top of the pipe in excess of the maximum trench width permitted will result in an increased load on the sewer pipe. If slopes are allowed to extend below this level, or if the width of the trench at this level is greater than the specified maximum width, additional strengthen- ing of the pipe is required, and accordingly, wherever such conditions x g PP � gY� exist and where the fill on the pipe exceeds 6 feet, the Contractor shall place a Class C concrete fill between the bottom of the trench and the level of the intrados of the pipe from the outside of the pipe to the undisturbed sides of the trench. No payment shall be made for such Class C concrete III-10 backfilling which shall become necessary on account of the Contractor's operations in excavating trenches of excessive widths below the specified levels. The elevations shown on the profiles of the sewers are those of the flowline of the pipes. In excavating the bottom of the trench in material other than rock, the Contractor shall allow for the thickness of the pipe where pipe sewers are installed, and shall shape the trench bottom by hand to fit the lower section of the pipe, as shown on the Plans, recessing for the bell holes where the bell projects beyond the barrel of the pipe in such manner as to relieve the bell of all load. If the bottom has not been excavated to conform to the outside of the pipes, as shown in detail on the Plans, the backfill necessary to the required grade for the outside of the pipe shall be made with crushed rock for bedding. Such crushed rock where excess excavation occurs, shall be placed at the Contractor's own expense. The elevations shown on the Plans for force mains are centerlines of the pipe. Force mains, sewer lines, and water lines shall have a mini- mum cover of 3 feet 0 inches unless otherwise shown on the Plans. Where bell-and-spigot cast iron or ductile iron pipe is used, bell holes shall be provided in the trench to relieve the bells of all strain. The trench shall be excavated to the depth required so as to provide a uniform and continuous bearing and support for the pipe on solid and un- interrupted ground at every point between bell holes, except that it will be permissible to disturb and otherwise damage the subgrade surface near the middle of each length of cast-iron pipe to permit the withdrawal of pipe slings or other lifting equipment for handling the pipe. Any part of the bottom of the trench excavated below the specified subgrade shall be cor- rected with suitable material thoroughly compacted as directed. The finished subgrade shall be prepared accurately by means of hand tools. If the material in the bottom of the trench is unstable or otherwise unsuitable for supporting the pipe, the unsuitable material may be exca- vated as directed by the Engineer. The quantity of such authorized addi- tional excavation shall be determined by the Engineer and paid for by the City at the unit price bid for "Class B Trench Excavation. " Where necessary to protect the labor, the work, or adjacent property and in all trenches with vertical sides deeper than 6 feet, the Contractor shall provide and install shoring. The sides of the trench shall be securely held by bracing or sheeting of either wood or steel. Shoring shall remain III-11 III in place until the backfill has proceeded to a point where it can be safely removed. If, in the opinion of the Engineer, damage is likely to result from withdrawing shoring, it shall remain in place. Payment for all lumber left in place as ordered by the Engineer will be paid for at the price bid per MFBM for "Lumber Ordered Left in Trench", which pay- ment shall cover the whole cost of furnishing all material, labor, equip- ment, tools and all other incidentals which may be necessary for placing the lumber in the trench. This payment shall not cover the cost of furnishing, placing and removing lumber used for bracing during construc- tion, which need not remain in place upon completion of the backfill. Payment for lumber used as temporary bracing shall be included in the price bid per cubic yard for "Class B Trench Excavation. " Payment for trench excavation in rock, including backfill and sur- plus disposal shall be made at the price bid per cubic yard for "Class A Trench Excavation". Payment shall cover the whole cost of furnishing all equipment, labor, tools, materials and all other incidentals which may be necessary for completing the excavation. It shall cover the whole cost of rerouting all storm water or sanitary sewage flows, of protecting adjacent improvements, maintaining temporary macadam or gravel surfaces in satisfactory and safe condition for use by traffic until permanent pavement restoration is carried out, and of cleaning up the site. Payment for Class A trench excavation shall be for the volume cal-' culated on the basis of the payline width of the trench, as herein specified for the various sizes of pipe sewers and force mains, the actual depth of rock removed or the depth from the upper rock surface to an elevation 6 inches below the required bottom of the pipe, whichever is the lesser, and the actual length of rock removed, up to the distance between centers of manholes except where the pipe sewer, force main, or other conduit is to be included in the lump sum bid for a structure. Class A trench excavation within the limits of the lump sum items shall not be measured and paid for separately. Payment for Class C concrete is covered in Section III, paragraph 18. Payment for Class B trench excavation, including backfill and sur- plus disposal, shall be made at the price bid per cubic yard for "Class B Trench Excavation" (including backfill and surplus disposal). Payment shall cover the whole cost of furnishing all equipment, labor, tools, matiq- ® riall and all other incidentals which may be necessary for carrying out the necessary excavation, pumping and fluming, and taking care of dry and storm water flows, protecting adjacent improvements, backfilling, including tamping of the backfill as herein specified, maintaining temporary 111-12 macadam or gravel surface in satisfactory safe condition for use by traffic until the permanent pavement restoration is carried out, disposing of the surplus excavated materials, and cleaning up of the site, including the furnishing, placing and removing of all sheeting and bracing which may be necessary during construction, but which is not ordered left in place and which is removed as the backfill is being carried out. Payment for Class B trench excavation shall be for the volume cal- culated on the basis of the payline width of the trench as herein specified for the various sizes of pipe sewers and force mains, the actual depth of Class B material removed, or the depth from the surface to the pipe flow- line, whichever is the lesser, and the length between centers of manholes for pipe sewers and the length of pipe for force mains, except where the pipe sewer, force main, or other conduit is to be included in the lump sum bid for a structure. Class B trench excavation within the limits of the lump sum items shall not be measured and paid for separately. Payline widths for trench excavation for pipe which are to be used in calculating the volume of excavation performed under this Contract are as follows: Size of Sewer in Inches Payline Width of Trench Aft 8-12 2 feet - 4 inches 15 2 feet - 8 inches 18 2 feet - 11 inches 21 3 feet - 3 inches 24 3 feet - 6 inches 27 3 feet - 9 inches 30 4 feet - 1 inch 36 4 feet - 8 inched 15. STRUCTURAL - EXCAVATION: The Contractor shall perform all structural excavation required on the Plans. Excavation shall extend a sufficient distance from the walls and footings to allow for forms for the work and for proper inspection except where the Plans indicate that concrete may be deposited directly against excavated surfaces. Excavated material not needed or not suitable for the finished grade shall be removed from the site at the Contractor's expense. All structural excavation indicated on the drawings or required by the specifications shall be included in the lump sum price bid for each III-13 structure, complete in place, and will not be classified, measured or paid for separately. Should any additions or changes to the Contract require any changes Ask in the amount of structural excavation required to be done by the Contractor, the unit prices for excavation stated in the Contract Agreement shall be used to determine the amount to be added to or to be deducted from the lump sum price for the structure involved. All excavation of material defined as Class A material in Section III, Paragraph 14, shall be classified as rock excavation. All excavation, except rock excavation, where the Contractor is re- quired to operate dewatering equipment, such as pumps or well points, will be classified as wet excavation. All other excavation, except rock excava- tion, shall be classified as dry excavation. All structural excavation, except rock excavation, which, in the opinion of the Engineer, cannot reasonably be excavated by machine shall be classified as hand excavation. All excavation, except rock excavation, not classified as hand excavation shall be classified as machine excavation. The amount of excavation to be measured for payment shall be ex- cavation not indicated on the Plans or reasonably inferred from the Plans and/or specifications. The amount of excavation to be paid for shall be based on a payline width for rock excavation for structures 15 inches from the finished inside line of the outer vertical walls, a payline width for earth excavation for structures 12 inches from the outermost line of the outer vertical walls, the actual elevation of rock, and the applicable unit prices in the Contract. The prices for excavation shall include all shoring, de- watering, backfilling, maintenance of backfill, disposal of waste material, and all other work incident thereto. 16. FILL AND BACKFILL: Fill and backfill shall be placed as shown on the drawings to pro- vide the finished grades shown on the Plans. All fill to be placed under structures shall be granular material. Other areas to be filled may be filled with granular material or non-granular material, except that the top 10 inches of all .lawn areas shall be topsoil. Except as otherwise specified or required, all fill and backfill shall be made with suitable earth free from debris, lumps, and perishable mate- rials in quantities considered excessive by the Engineer. Materials shall be processed so that the material in each layer of fill and backfill shall contain the amount of moisture required for optimum compaction as deter- mined by the Engineer. The moisture content shall be as uniform as III-14 i practical throughout the layer. No frozen material shall be placed as fill or backfill nor shall fill or backfill be placed upon or against frozen sur- faces. All materials shall be placed by methods hereinafter specified or as otherwise approved by the Engineer. Backfill shall not be placed upon or against concrete surfaces, prior to 14 days after placing of the concrete and then only after approval of the Engineer. Backfill shall be brought up evenly on each side of structures as far as practical. Prior to placing backfill, forms for concrete shall be removed and the excavation shall be cleaned of trash and debris. Prior to placing any fill, the ground to be occupied by the fill shall be cleaned of all trees, trash, or other objectionable material and the surface scarified to a depth of 6 inches to permit proper bonding. Fill and backfill shall be placed or spread in layers not more than 8 inches in thickness prior to compaction and compacted with rubber-tired rollers or vibrating equipment, except as specifically noted otherwise in these specifications. The Contractor shall process the fill material as re- quired to bring them to approximately the correct content for optimum compaction. Material to be placed that is too wet for proper compaction shall be spread and permitted to dry assisted by scarifying or other suit- able means, if necessary, until the moisture content is reduced to a value satisfactory to the Engineer. When material is too dry, the Contractor shall immediately before placing and spreading of the material for com- paction, wet the rolled surface of the preceding layer of the foundation. After placing and spreading the dry material on the wet surface, it shall be sprinkled and harrowed prior to compaction. Fill and backfill to be placed within 2 feet of vertical concrete sur- faces of structures and in other areas that cannot be compacted as described above, shall be placed in uniform horizontal layers not to exceed 4 inches in thickness before compaction. Each layer shall be thoroughly compacted with approved mechanical tampers before the next succeeding layer is placed. The backfilling of the completed pipe sewers and force mains shall commence immediately upon the completion of the sewer, with care being taken that the operation of backfilling does not disturb the pipe joints. The initial backfill over and around pipe sewers to the undisturbed sides of the trench shall be placed in 6-inch layers which shall be thoroughly hand-tamped to an elevation not less than one foot above the extrados of the pipe. The material used for this initial backfilling shall be the excavated natural soil free from all other foreign substances such as debris, rocks, cinders, ashes, lumps or organic matter. No walking over the completed pipe sewer will be 111-15 allowed until the backfill has been carried to at least one foot above the top of the sewer. In lieu of tamping the backfill, the Contractor may, at his own option and at his own expense, complete the backfill to one foot above the top of the sewer with crushed rock. Where the Contractor excavates below the planned subgrade for pipe lines, the over-excavation shall be backfilled with granular material well compacted in 6-inch layers; Only granular material placed in over- excavation authorized by the Engineer will be measured and paid for at the price bid per cubic yard for "Granular Material for Trench Subgrade Re- placement, " which payment shall cover the whole cost of furnishing all materials, labor, equipment, tools and other incidentals necessary to fur- nish and place the granular material. The volume to be paid for under this item shall be limited to the volume computed within the payline widths and for the depths and lengths as ordered by the Engineer. Crushed rock placed in over-excavation not authorized by the Engineer shall be included in the cost of "Class B Trench Excavation. " Backfilling shall be completed to ensure restoration of the ground surface to its original condition. Backfill in open fields and on railroad property, except near switches and other places to which railroad personnel will require access, may be completed without further compaction above one foot over the extrados, or without flushing. The fill shall be mounded over the trench to allow for future settlement. Near switches and other places requiring access, as designated by the,rai.lroad, the backfill shall be compacted so that no ap- preciable settlement will occur and the fill shall be left level with the exist- ing ground surface. Backfill of the trenches crossing beneath concrete, asphaltic con- crete or bituminous macadam pavement and railroad tracks shall be made with Granular materials. Payment for granular fill will be made at the bid price per cubic yard for "Granular Backfill" for the volume in place after final compaction. The volume of granular fill used beneath pave- ments which are removed and replaced shall be computed from the actual length of the trench filled, the payline width and the depth equal to the average distance from road subgrade elevation to one foot above the top of pipe. ® All surplus excavated material which is not usable for backfill shall be hauled from the work site. The cost of all work included in this paragraph shall be included with the cost of the excavation requiring the back£illing or filling operation, , except as noted above. III-16 17. CONCRETE ENCASEMENT: The pipe shall be encased where shown on the Plans or where directed by the Engineer with Class B concrete of the dimensions shown on the detail on Sheet 10. The concrete may be placed against the undis- turbed earth sides and bottom of the trench. Side forms may be used if necessary and if approved by the Engineer. Horizontal joints will not be permitted in unreinforced encasement. Pipe shall be supported and held in place before and during placing of concrete. The trench shall be kept dry and free of water until the concrete has set and can not be damaged by water. Backfill above the top of encasement to a level one foot above the top of pipe shall be carefully compacted select job-excavated material. This compacted backfill below a level one foot above the pipe shall not be placed until 12 hours after the concrete encasement has been completed. Class B concrete for encasement required where shown on the Plans or as directed by the Engineer shall be paid for at the price bid per cubic yard for "Class B Concrete", which payment shall cover the whole cost of furnishing all materials, labor, equipment, tools, and all other incidentals which may be necessary for furnishing and placing the Class B concrete.

Class C concrete shall be used for bedding. Concrete bedding shall be placed only in dry trenches. Backfill above the concrete shall be placed as stated in Section III, paragraph 16. 111-17 Payment will be made for Class C concrete used in bedding in rock trenches at the price bid per cubic yard for "Class C Concrete". Such payment shall cover the whole cost of furnishing all materials, labor, equipment, tools, and all other incidentals which may be necessary for AM furnishing and placing the Class C concrete. qW Class C concrete for bedding in rock trenches for the various size sewers shall be measured and paid as tabulated below: Nominal Size Cubic Yards of Class C Concrete of Sewer per Lineal Foot of Sewer (inches) 8 0. 04 10 0. 04 12 0. 05 15 0. 06 18 0. 07 21 0. 08 24 0. 09 27 0. 11 30 0. 12 36 0. 15 19. CONCRETE CRADLE: Cradle required by the Plans and specifications shall be of low- slump Class B concrete and of the dimensions shown on the Plans. The , concrete shall be placed against the undisturbed earth or rock sides and bottom of the trench. - horizontal construction joints will not be permitted above the level of th6 bottom of the pipe or within the limits of the cradle as shown on the Plans. The trench shall be kept dry and free of water until the concrete has set and cannot be damaged by water. Pipe shall be held in place to prevent displacement during placing of concrete. Backfill above the top of the concrete cradle to a level one foot above the top of the rpipe shall be selected job-excavated earth or granular bedding material carefully placed and compacted as described in Section III, paragraph 16. The compacted backfill below a level one foot above the pipe shall not be placed until 12 hours after the concrete cradle has been completed and hardened. Payment will be made for Class B concrete in cradles at the bid price p6r cubic yard for'Class B Concrete!' The quantity for which payment will be made will be 0. 3 cubic yards per lineal foot of 36-inch pipe cradled. 111- 18 Such payment shall include the entire cost of furnishing and placing the concrete cradle as shown on the Plans. It also shall include the costs of supporting and securing the jointed pipe against movement during the placing of the concrete. 20. INSTALLATION OF VITRIFIED CLAY AND CONCRETE SEWER PIPE: Each pipe shall be set on end and rung before laying and any pipe found to be cracked or damaged shall be plainly marked in such a manner that the marking will not rub or wash off, and shall subsequently be removed from the site. Pipe shall be laid with the bell or socket uphill to the line and grade given by the Engineer on a prepared subgrade excavated and shaped as hereinbefore described. The prepared subgrade shall be kept free from water during the laying of the pipe. Line and grade shall be maintained by the use of no less than three batter boards set at 25-foot intervals and a top line. Except by special permission of the Engineer, no pipe shall be laid except in the presence of an inspector. Each pipe as laid shall be plumbed for line with a plumb bob, and graded with a grade stick for ele- vation. The accuracy of the finished line and grade of the pipe shall be obtained in the preparation of the subgrade. As the work progresses, the interior of the sewer shall be cleaned of all dirt or debris of any description. Pipe shall, be laid through line manholes, and the upper half re- moved after the invert is completed, unless half-pipe is used. For reinforced concrete pipe, the gasket shall be a continuous rubber ring and shall. be the sole element depended on to make the joint watertight. Gaskets shall be properly placed on the clean spigot end of the pipe with the proper adhesive. Before assembly or sending "home" the pipe in the trench, the exposed gasket surfaces shall be coated with lubricant. 1,To petroleum product shall be used as a•lubricant. For vitrified clay pipe, the pipe shall be so handled and stored that the jointing material will not be deformed or damaged. The joints shall be connected by first brushing the proper lubricant sealer on the clean mating surfaces as recommended by the pipe manufacturer. The spigot end shall be centered on grade into the bell end of the downstream pipe and shoved "home". The pipes shall be joined not later than five min- utes after the application of the lubricant sealer. III-19 r All sewer pipe shall be laid and handled so that the allowable leak- age shall not be exceeded as measured by the tests hereinafter described. All extraneous material shall be removed from the completed sewer pipes and manholes before they are accepted by the City. All vitrified clay pipe and concrete sewer pipe will be measured and paid for as such except where it is noted on the Plans that the pipe is to be included with the lump sum bid for a structure. Each size of pipe shall be measured and paid for at the corresponding unit price bid for each particular size and type of pipe installed. The length of pipe shall be the horizontal distance between the centers of manholes as measured along the alignment of the pipe. The unit prices for vitrified clay pipe and concrete sewer pipe of the various sizes and types shall include all material, labor and equipment necessary to install and test the pipe, complete in place, in accordance with the Plans and specifications. 21. INSTALLATION OF CAST IRON AND DUCTILE XROMPIPE: Handlin Pi e. Cast iron and ductile iron pipe shall not be dropped, P let roll and collide with another pipe, or be subjected to any unnecessary jar, impact, or other treatment that might crack or otherwise damage the pipe while being transported, unloaded or handled. Proper and suitable tools and appliances for the safe and convenient handling and installing of the pipe and fittings shall be used. Care shall be taken to prevent any coating on the inside of pipe and fittings from being damaged. All pieces shall be carefully examined for defects, and no piece shall be installed which is known to be defective. If. a defective piece should be discovered after having been installed, it shall be removed and replaced with a sound one in a satisfactory manner by the Contractor at his expense. Cutting Pipe. Cutting of cast-iron pipe shall be done in a neat manner, without damage to the pipe or to the cement lining therein. Pipe cuts shall be smooth, straight, and at right angles to the pipe axis. All cutting of pipe shall be done with mechanical pipe cutters. Cleanipa. The interior of all pipe and fittings shall be thoroughly cleaned before they are installed and shall be kept clean until they are accepted. in the completed. work. All lumps, blisters, and excess coating shall be removed from exterior spigot and interior bell surfaces of pipe with mechanical or push-on joints. Such surfaces shall be wire-brushed and wiped clean and dry and free from oil and grease before placing the 111-20 spigot in the bell. All joint contact surfaces shall be kept clean until the jointing is completed. Every precaution shall be taken to prevent foreign material from entering the pipe while it is being installed. No debris, tools, clothing or other materials shall be placed in the pipe. Inspection. During installation, while suspended and hanging free, each pipe and fitting shall be inspected for defects and rung with a light hammer to detect cracks. All defective, damaged, or unsound pipe and fittings shall be rejected and removed from the site of the work. Installation in a Trench. Before laying the pipe in the trench, the bottom of the trench shall be carefully graded and prepared and bell holes excavated so that the pipe shall have a uniform support along its entire length except at bell holes, and shall not be allowed to rest on hard sup- ports through a portion of its length only. In trenches with a rock bottom, Class C concrete bedding as defined above shall be used. The cover over the pipe shall be a minimum of 36 inches unless otherwise designated on the Plans. At all times when pipe laying is not actually in progress, the open ends of the pipe shall be closed by temporary watertight plugs or other approved means. If water is in the trench when work is resumed, the plug shall not be removed until all danger of water entering the pipe has passed. Force mains shall be laid with a continuous positive or negative slope between the centerline elevations shown on the Plans; however, the slope does not have to be uniform between the designated elevations. The centerline elevations of the pipe shall accurately correspond to the elevations shown on the Plans in locations where elevations are specifically designated. Where no difference in elevation is shown between points, the pipe shall be laid on an essentially flat grade. The centerline elevation of pipe to be laid on a flat grade shall not vary more than 3 inches above or below the designated elevation and successive pieces of pipe shall not be more than 1 inch above or below the adjacent pieces of pipe. Concrete anchorage or blocking shall be placed behind all tees and bends to undisturbed earth in the trench. Concrete shall be placed in such a manner that joints can be maintained unless specific permission of the Engineer has been obtained to encase them. Blocking ehind tees and 90-degree bends shall be such that an area g g ® of concrete three times the cross section of the pipe shall bear against un- disturbed earth. All other bends shall have 50 per cent of the above requirement. All force mains shall be laid and handled so that the allowable leakage, as measured by the tests herein described, shall not be exceeded. III-21 M Installation in a Structure. All pipe and fittings shall be installed in structures, as shown on the Plans, and shall be complete in every respect, providing a system which will operate satisfactorily and quietly. All piping connecting to equipment shall be provided with a companion flange, a flexible coupling, or a flanged adapter so that the piping may be readily dismantled from the equipment. All piping shall be installed in such a manner that it will be free to expand and contract without injury to itself or its supporting structure. All necessary supports shall be installed to hold the piping and ap- purtenances in a firm and substantial manner at the lines and grades indicated on the Plans or specified. Unless otherwise specifically noted, pipes and fittings shall be supported at least every 9 feet, and each valve, 3 inches and larger, shall be supported on both sides with a support within 2 feet of the valve. Bell and spigot pipe shall be supported at each joint. Unless otherwise shown on the Plans, waterstops shall be provided where all cast-iron pipes pass through concrete or masonry walls by using wall castings or brazed steel collars approved by the Engineer. Jointing. a. Mechanical Joints. Mechanical joints shall be carefully assembled in accordance with the manufacturer's recommendations. If effective sealing is not obtained, the joint shall be disassembled, thor- oughly cleaned and reassembled. The Contractor will not be permitted to overtighten bolts in order to compensate for poor installation practice. b. Push-On Joints. Push-on joints shall be carefully assembled in accordance with the manufacturer's recommendations regarding gasket installation and other jointing operations. c. _Flanged Joints. All joints in flanged piping shall be brought to exact alignment, and all gaskets and bolts or studs inserteDd' in their proper places. When bolting the joints, care should be taken to see that there is no restraint on the opposite end of the pipe or fitting which would prevent uniform gasket compression or which would cause unnecessary stress in the flanges. Bolts or studs shall be uniformly tightened around the joint in a manner which will provide uniform compression of the gasket. Flexible joints shall not be tightened until all flanged joints affected thereby 1 ® have been tightened. d. Flexible Couplings and Flanged Adapters. Flexible couplings and flanged adapters shall be installed in accordance with the manufacturer's printed instructions and shall make watertight joints in the pipes being connected. 111-22 Payment. Cast iron and ductile iron pipe shall be measured and paid for at the unit price bid per lineal foot installed for each particular pipe size installed except where within the limits shown on the Plans, the pipe shall be included in the lump sum bid for the structure involved, or AM where the pipe is in a tunnel and the cost of the pipe in place is included in the lump sum bid for tunnel. Cast iron and ductile iron pipe shall be measured along the top centerline of the pipe actually installed. The unit price for cast iron and ductile iron pipe shall include all material, labor and equipment necessary to install the force mains, in- cluding pipee,, fittings, jointing of pipe, concrete blocking for bends, and testing of the pipe. 22. MANHOLE CONSTRUCTION: Manholes shall be built of brick to the dimensions and at the loca- tions as shown on the Plans or as directed by the Engineer, as rapidly as the construction of the sewer will permit. All bricks in each course shall be headers and break joints with those in the adjoining course. Each brick shall have full mortar joints on the bottom and sides, which shall be formed at one operation by placing sufficient mortar on the bed and forcing the brick into it. Horizontal joints shall not exceed 3/8 inch and vertical joints on the inside of the manholes shall not exceed 1/4 inch. The mortar for the brick work of the manholes shall be made of one part of portland cement and three parts of sand, complying with the fine aggregate specifications hereinbefore described. The sand and cement shall be thoroughly mixed dry, and the necessary quantity of clean water shall be added so as to produce a stiff mortar of the proper consistency, which mix shall be thoroughly worked with proper tools. All joints on the inside of the manholes are to be carefully rubbed full and struck as the manhole is built up, Upon completion of each man- hole, all waste mortar and debris shall be immediately removed from the bottom and the invert shaped to the dimensions shown on the Plans and all bottom joints struck or pointed. The jointing of the brick work shall be such that the manhole will be watertight so that no ground water infiltra- tion through the manhole joints will occur. The outside of the manhole shall be covered with a mortar plaster coat 1/2 inch thick. A single rowlock shall be turned over all incoming and outgoing pipes. 1 111-23 The inverts of all manholes located at changes in alignment of the sewer shall be shaped to the incoming and outgoing pipes and smoothly curved from pipe to pipe to the top of invert at springline. On line manholes, pipe shall be laid through the manhole and the upper half removed after the invert has been completed. Half pipe may be used. As an alternate, manholes may be built of Class A concrete, pre- cast or poured in place. Joints of precast manhole sections shall be formed entirely of concrete employing a rubber gasket conforming to ASTM Desig- nation C443. Joints shall be self-centering. The gasket shall be.the sole element utilized in sealing the joint. Plans for concrete manholes must be approved by the Engineer. Forms may be of steel or clean lumber, assuring a smooth finished surface. Duri=g;the construction of each manhole, cast-iron steps conform- ing to the specifications for cast-iron manhole steps hereinbefore described, shall be set in place on the inside of the manhole, at the spacing shown on the Plans. The top step shall not be more than 2 feet below the top of the manhole. The ends of the steps shall be firmly built in the wall, allowing the steps to project 5 inches from the inside of the manhole. Where shown on the drawings, manholes shall be built over existing sewers and the ex- isting sewer plugged. The sewers requiring plugging will be filled with concrete for a length of not less than 2 feet. Manholes shall be covered with standard cast-iron frames and covers of the dimensions and materials herein specified. Frames shall be set in place and closed with covers. All manholes will be measured and paid for as manholes of the ap- propriate depth as bid in the Proposal. The depth of manholes shall be measured from the invert of the sewer to the top of the cast-iron frame and shall be paid for at the appro- priate unit price bid. Payment for all work included in this paragraph shall be included in the unit price for the various depth manholes and shall include all neces- sary labor, material and equipment for constructing the manholes, including additional excavation beyond the trench payline width and depth, concrete base, cast-iron frame and cover, backfilling and all other work necessary to construct the manhole in place. HI-24 Outside drops shall be constructed as shown on the Plans. :Payment will be made for completed outside drops as an addition to the payment dM made for the completed manhole. Payment will be made for each drop at the lump sum bid price for each, and shall include all costs of excavation, lumber left in trench, concrete or brick masonry, drop pipe; pipe elbow, jointing, and the additional cost of the pipe junction on the sewer and its concrete encasement. 23. PIPE SEWERS AND FORCE MAINS IN TUNNEL; Pipe sewers and force mains in short tunnel at crossings of rail- roads shall be constructed when required by the Plans and in accordance with these specifications. The Contractor may request permission to construct the pipe sewer at a crossing of a railroad in a bored hole or in a jacked liner in accordance with a.method of construction approved by the Engineer and the railroad. The carrier pipe, shall be of the size and material shown on the Plans. The Contractor shall carry out the work of tunneling and supporting the tunnel face, roof, walls and floor so that there will be no fall, flow, caving or heaving of earth or other materials into the tunnel excavation, nor any other cause for endangering human life or any public or private property above or adjacent to the tunnel. If there should be any fall or movement of earth into the tunnel at any time, the Contractor shall proceed with the work with all necessary precautions and in such a manner as will ensure the safety of life and of all utilities and public and private property above and adjacent to the tunnel. If any utility above or adjacent to the tunnel is endangered or has been damaged because of the tunneling opera- tions or movements of earth, the owner shall be notified immediately and shall be given access to the work to carry out all necessary safeguards and repairs to such utility. If any public or private property is endangered or has been damaged, it shall be repaired at the Contractor's expense. All cost and expense to the Contractor of carrying out the above require- ments shall be deemed to be included in his bid prices for the completed tunnel s. The Contractor shall make all excavations necessary for the con- struction of sewers in tunnel, whether in earth or partly in earth or in rock; shall furnish, place, and maintain all sheeting, bracing, lining or casing required to support the tunnel floor, roof, sides, and face until the carrier pipe and its bedding, jointing, encasement, and backfilling has been com- pleted. All liners shall remain in place. Methods are optional with the Contractor, provided the work can be carried out expeditiously, carefully r III-25 and in compliance with these specifications. Care shall be used in trim- ming the surfaces of the excavated section and in placing the liners or AM sheeting and bracing, so that the required minimum clearance between the outside of the pipe and the final position of the liners. sheeting and bracing in the tunnel will be attained without any deviation in carrier pipe alignment. Sheeting or lining must be placed and held tightly against the trimmed earth surface of the excavated section so that there will be no voids between the earth and the lining or sheeting placed against it. No part of the lining, bracing, or flanges of steel liner plates shall project closer to the outside of the pipe or pipe bells than 2 inches. All excavated material not required for backfilling abandoned shafts shall be removed from the site and disposed of by the Contractor at his expense. The Contractor shall furnish and operate all necessary pumping equipment of ample capacity and make all necessary provisions to keep tunnels free of water during construction, and to satisfactorily dispose of such water. During placing of concrete, drainage and pumping shall be so arranged that concrete is placed in the dry and that no water will flow over the concrete until it has set and will not be damaged, and not sooner than two hours thereafter. The Contractor shall have on hand at all times sufficient equipment in good working order for all ordinary emergencies that are likely to arise. If cavities result between the actual surfaces of excavation and the tunnel lining, whether from avoidable or unavoidable causes, they shall be completely filled with a uniform sand-cement grout, consisting of one part portland cement and seven parts sand, placed under pressure through grout holes in the steel liner plates. The grout-holes shall be so placed and the grout be placed in such sequence as to ensure completely filling the cavities and carrying the load uniformly from the undisturbed material to the tunnel lining. After the tunnel section is excavated and lined, the pipe shall be placed on abed of moist Class B concrete at the approximate center of the tunnel and to the required grade and alignment. The Class B concrete shall be uniformly mixed with only a minimum amount of water to such stiffness that, after placing to the thickness with allowance for compacting, the concrete will hold the pipe to its required grade and alignment without further settling. If settlement is sufficient as to create drainage pockets in the invert or if the deviation from the required flowline elevation exceeds one-half inch, the pipe shall be removed and additional concrete bedding added. No blocks, wedges, or other devices shall be used to hold the pipe III-26 to grade or to prevent the full uniform support of the pipe on the concrete bedding. Care shall be used to avoid damage to the pipes or to the liner plates as the pipe is moved through the tunnel. Damaged pipe or plates shall be replaced when so directed by the Engineer. After laying and bedding each section of the pipe, the compacted Class B concrete bedding shall be continued to the level of the pipe spring- line to fill all spaces between the outside of the pipe and the inside surface of the lining or the prepared surface of the rock (if the tunnel is in sound rock). Above the level of the springline, all spaces between the outside of the pipe and the inside surface of the lining or the prepared surface of the rock (if tunnel is in sound rock) shall be completely filled with a uni- form sand-cement mortar consisting of one part portland cement and seven parts sand or with Class B concrete. Construction pits shall be completely abandoned, and unless required by the Engineer, all sheeting, bracing, etc. , may be removed or left in place at the Contractor's option and no sheeting, bracing, etc. , left in place at the Contractor's option will be paid for by the City. If the Engineer requires leaving the sheeting, bracing, etc. , in place, payment will be made as indicated in Section III, paragraph 14. Any temporary shaft sheet- ing, bracing, or walers left in place shall be cut off at least two feet below finished grade before the backfill of the shaft is completed. Construction pits shall be backfilled with suitable job-excavated material and compacted so that no appreciable settlement will occur. The backfill shall be leveled with the natural ground surface surrounding the pit. Payment for tunnels and the pipes laid therein shall be made at the lump sum bid for each length of tunnel presuming that only Class B excava- tion will be encountered. Should Class A excavation be encountered, the additional cost of this excavation will be compensated for at the unit cost of Fifty Dollars ($50. 00) per cubic yard for "Class A Tunnel Excavation". The volume of Class A excavation will be the measured volume within the outside diameter of the liner pipe. The lump sum payment for each tunnel shall be regarded as full compensation for the cost of the shafts, headings, excavation, liner plates, grouting, drainage, lighting, cradling, pipe in place, bedding, backfilling, providing any necessary concrete collars, and any additional costs required to complete the tunnel crossing. 24. STANKS OR SHORT TUNNELS: The force main or gravity sewers shall be constructed in stanks or short tunnels where requested by the Contractor and approved by the Engineer. 111-27 The top of the tunneled length shall slope upwards to Each entrance to permit adequate backfilling. The tunneled portions shall be sufficiently large to allow adequate working room at the sides and above the. pipe to be installed. ® The tunnel bottom shall be shaped as nearly as practicable. to the bottom of the pipe with provision for pipe bells. A bedding of crushed limestone and screenings shall be placed to fill any irregularities in shaping and to ensure a uniform continuous bearing for the pipe barrel at the re- quired elevation without load on the pipe bells. After firmly bedding and jointing the pipe, the crushed limestone and screenings shall be solidly packed around the pipe to the level of the top of the pipe. The remaining space above the top of the pipe shall be packed solidly with tamped earth free from debris, rocks, lumps or organic matter or, at the eleet3onro£i the Contractor, with tamped limestone screenings or compacted sand- cement mix. The Contractor shall carry out the work of stanking in a safe, pru- dent manner to avoid endangering human life or property. No separate payment for the construction of the gravity sewer or force main in stanks or short tunnels shall be made. Payment for such stanks or short tunnels shall be considered as included in the price bid for "Class B Trench Excavation". 25. LEAKAGE TESTS FOR GRAVITY SEWERS: Upon completion of a section of the sewer, the Contractor shall de- water it and conduct a satisfactory test to measure the infiltration for at least two hours. The amount of infiltration., including manholes, Y-branches, and connections shall not Exceed 500 gallons per inch-diameter per mile of sewer per 24 hours. The Contractor shall be responsible: for the satis- factory watertightness of the entire section of sewer and shall satisfactorily repair all joints or other locations that are not sufficiently watertight. For making the infiltration tests, underdrains, if used, shall be plugged and other groundwater drainage shall be stopped to permit the ground water to return to its normal level insofar as practicable. Allow- ance shall be made for water which may enter the sewer through pipe connections and inlets during the infiltration test. As required, suitable bulkheads shall be installed to permit the test of the sewer. Where the groundwater level is less than one foot above the top of the pipe at its upper End, the sewers shall be subjected to an internal -Z III 8 pressure by plugging the pipe at the lower end and then filling the pipelines and manholes with clean water to a height of 2 feet above the top of the sewer at its upper end. Ask The rate of leakage from the sewers shall be determined by measur- ing the amount of water required to maintain the level 2 feet above the top of the pipe for a period of at least 2 hours, commencing one hour after the pipeline filling is completed. Leakage from the sewers under test shall not exceed the require- ments for leakage into sewers as hereinbe£ore specified. The Contractor shall construct such weirs or other means of measurements as may be required, shall furnish water and shall do all necessary pumping to enable the tests to be properly made. Should the sections under test fail to meet the requirements, the Contractor shall do all work of locating and repairing leaks and retesting as the Engineer may require without additional compensation. Payment for all work included in this section shall be included in the payment for pipe in place as herein specified. 26. TESTING OF FORCE MAIN: The force main shall be tested to a pressure of 100 psi after the line has been backfilled. The leakage shall be measured by pumping into the line with a purnp capable of maintaining the required pressure and metering the amount of water necessary to sustain the pressure for a period of four hours. The test when so conducted shall indicate a, leakage of not more than 50 gallons per inch of pipe diameter per mile per day and no leaks shall become apparent on the surface of the ground. Should sur- face leaks become apparent, or should the leakage exceed that specified, the leaks shall be located and repaired and the line retested until it fulfills the above requirements. Payment for all work included in this section shall be included in the payment for pipe in place as herein specified. 27. CONCRETE: The Contractor's attention is called to the fact that the specifica- tions for Class A and Class B concrete carry three limiting factors, all of which shall be complied with. These factors are: (1) minimum strength, -2 1119 (2) ininimum volume of cement per cubic yard of concrete, and (3) maxi- mum volume of water per sack of cement. a. Classes of Concrete. Class C concrete may be used for fill in trenches as required for pipe in rock trench, or for overexcavation of the trench. Class B concrete shall be used for encasement and cradling of pipe or for blocking for cast iron or ductile iron pipe. All other concrete used on this project shall be Class A concrete, unless otherwise specifi- cally noted on the Plans. b. Class A Concrete. Class A concrete shall have a minimum compressive strength of 3, 500 pounds per square inch in 28 days and shall consist of the mixture which results in one cubic yard of concrete to each batch of fine and coarse aggregate and water used to each six sacks of cement. Total water shall be limited to a maximum of 6-1/2 gallons per sack of cement. The fine and coarse aggregates for each batch of concrete where monolithic construction is to be carried out shall be accurately weighed; the exact weight of each batch shall be that necessary to produce a dense workable concrete with the yield per sack of cement as herein specified when mixed within the limitations of the amount of water herein specified. Where small batches of concrete are to be used and the concrete is mixed on the site, Class A concrete shall be considered as that mixture consisting of 2 cubic feet of dry fine aggregate, not more than 3-1/2 cubic feet of dry coarse aggregate to each sack of cement, mixed with not more than 6-1/2 gallons of total added water. c. Class B Concrete. Class B concrete shall have a minimum compressive strength of 2, 000 pounds per square inch in 28 days and shall consist of the mixture which results in one cubic yard of concrete to each batch of fine and coarse aggregate and water used to each four sacks of cement. Total water shall be limited to a maximum of 8-1/2 gallons per sack of cement. Where small batches of concrete are to be used and the concrete is mixed on the site, Class B concrete shall be considered as that mixture consisting of 3 cubic feet of dry fine aggregate, not more than 5 cubic feet of dry coarse aggregate to each sack of cement, mixed with not more than 8-1/2 gallons of total added water. d. Class C Concrete. Class C concrete shall consist of the mix- ture which results in one cubic yard of concrete to each batch of fine and ill coarse aggregate and water used to each two sacks of cement. Total water shall be limited to a maximum of 9-1/2 gallons per sack of cement. e. Determination of Added Water. In determining the amount of added water, allowance should be made for the moisture content in the 111-30 aggregates. In measuring the fine aggregate by volume for small batches of concrete, if the aggregate is wet, allowance should be made for the bulking on account of the presence of moisture. f. Proportioning. The concrete mixtures will be approved by the Engineer from design mix tests. All materials required for these. tests • shall be supplied by the Contractor from samples taken from the approved source of supply. At any time during the construction period, the relative weights of fine and coarse aggregates as determined by the original mix design may be varied slightly in order to ensure the use of the least amount of fine aggregate which will produce workable concrete with the slumps specified. The water content of the concrete shall at all times be the mini- mum necessary to properly place the concrete. It shall be regulated as required to adjust for any variation in the moisture content or grading of the aggregates. Addition of water to compensate for stiffening of the con- crete before placing will not be permitted. Uniformity of concrete con- sistency from batch to batch will be required. All concrete shall be proportioned by weight. Allowance must be made for the weight of moisture in the aggregates in order to determine the amount of additional water required for the given. concrete mix design. g. Air-Entrained Concrete. An air-entraining admixture, ap- proved by the Engineer may be used in the concrete should the Contractor desire toi.rpp,rove the workability of the concrete. No additional payment will be made for the -use of an admixture approved by the Engineer at the Contractor's request. The air-entraining admixture shall be added to the concrete during the process of mixing. The agents shall be accurately measured and dispensed by means of an approved adjustable mechanical dispenser which will automatically and gradually discharge the required amount of material into the mixing water. The entire amount of air- entraining agent shall be fully discharged before all of the mixing water has entered the drum of the mixer. The dispenser shall be so constructed that it can be accurately calibrated for the quantity of agent discharged at various settings and shall be provided with means by which the discharge can be readily diverted from the stream of mixing water to a container for measurement. Class A concrete which contains an approved admixture shall con- tain 5 per cent plus or minus 1 per cent of entrained air by volume. The volume of entrained air in the freshly mixed concrete will be measured by the Engineer by the. volumetric method, Test for Air Content of Freshly 111-31 Mixed Concrete by the Volumetric Method, ASTM Designation C173, or by the pressure method, Test for Air Content of Freshly Mixed Concrete by the Pressure Method, ASTM Designation C231. Mixes will be designed for the recommended air content and adequate control shall be provided to keep Allk the air content within the required limits. h. Consistency. The consistency of the concrete shall be such that the slump, when measured according to Test for Slump of Portland Cement Concrete, ASTM Designation C143, is the lowest compatible with work- ability and ease of placing. In general, the slump shall not exceed the following: Kind of Work Maximum Slump in Inches Mass Footings and Slabs 3 Thin Slabs and Thick Walls 4 Walls 15-Inch and Thinner 4-1/2 No additional water shall be added at the site of placement except with permission and under strict supervision of the Engineer and then only in an emergency. Such additional water shall be added only in small in- crements and then only in the smallest amount necessary within the required limits of consistency for the particular work, and shall be uniformly mixed and incorporated into the unplaced concrete before deposition in the forms. i. Mixing. Concrete required for blocking, encasement and other uses incidental to the installation of pipe involving small quantities may either be mixed by machine or by hand. All other concrete shall be mixed by machine. j. Mixing by Machine. The mixer to be used shall be so designed as to take one complete batch of materials using whole bags of cement only and to mix that batch thoroughly before any portion of it is withdrawn and any portion of the succeeding batch is introduced. In no case shall the volume of the batch to be mixed be greater than the amount of materials which can be loaded and mixed in the mixer without any loss during the loading or mixing by spilling. The mixer shall be equipped with a water tank accurately calibrated so that the required amount of water can be added to each batch, and with a batch meter or other suitable attachment for satisfactorily locking the discharging device so as to prevent the emptying of the drum until all of the materials have been mixed together for the minimum time required. After all the ingredients, including water, have been placed in the drum, they shall be thoroughly mixed in the mixer for a period of not less 111-32 than one minute. During this period the drum shall make not less than 14 nor more than 20 revolutions per minute. k. Central Plant Concrete Mixing. In lieu of mixing on the job by machine or by hand, central plant concrete will be permitted, provided the concrete conforms to the proportioning hereinbefore specified, is mixed at a central plant or in transit in equipment approved by the Engineer, and in conformity with current ASTM Specifications for Ready-Mixed Concrete (C94). The concrete shall be delivered to the job in batches of such size that it can be conveniently handled without getting up during placing, without segregation of aggregates, and of satisfactory consistency to ensure a uni- form concrete mixture when placed. 1. Hand Mixing. Where hand mixing of concrete is permitted, it shall be carried out on watertight boards or pans in not more than 2-sack batches. The cement and fine aggregates shall first be mixed dry until a uniform color is obtained. The water shall then be gradually added and the mixture made into a mortar, adding additional water until the desired consistency is reached. The coarse aggregate shall then be spread upon the mortar and covered with mortar. The whole mass shall then be cut through and turned over not less than four times or until thoroughly mixed with a uniform homogeneous mixture obtained before being removed from an the mixing board or pan in the place where it is to be deposited. The total amount of water shall not exceed the limitations hereinbefore specified for Class A, B, or C concrete. m. Forms. Forms for concrete shall be rigidly braced so that they cannot bulge or warp and leave an unworkmanlike finished surface. They may be constructed of any material with sufficient strength which will give the finished work a satisfactory surface. They must be sufficiently tight so that mortar cannot escape from the concrete in appreciable quantity. Forms shall be cleaned and be thoroughly moistened or treated with form oil before concrete is placed. All exposed exterior concrete corners shall be chamfered one inch. n. Reinforcing. All reinforcing shall be rigidly fastened in the forms prior to the pouring of any concrete in such manner that the steel will be held accurately to the location shown on the Plans. Steel shall be cleaned of rust, scale, oil, or other surface matter before being placed in forms. o. Wall Fittings and Anchor Bolts. Wall fittings and anchor bolts shall be installed as shown on the Plans. p. Placing. The methods and equipment used for transporting concrete and the time that elapses during transportation shall be such as III-33 will not cause appreciable segregation of coarse aggregate, or slump loss in excess of one inch in the concrete as it is placed in the project. Am Before placing concrete in the forms or in the place of deposit, all debris and foreign materials, soft earth, or mud, shall be removed. Water shall be removed from the place of deposit. No concrete shall be placed in water. Steel or wood forms shall be oiled and treated to prevent adhesion of concrete and damage to the concrete surface upon removal of the forms. Concrete shall be placed as nearly as practicable in its final position to avoid segregation due to rehandling or flowing. Concreting shall be carried on at such a rate that the concrete is at all times plastic and flows readily into the forms and around reinforcing. No concrete shall be used that has partially hardened or has been contaminated by foreign material or that has been retempered. Placing of concrete shall be performed only in the presence of a duly authorized representative of the Engineer unless inspec- tion is waived in each specific case. The temperature of concrete when it is being placed shall be not more than 90 degrees F. or less than 40 degrees F. Concrete shall be placed before initial set has occurred. Before depositing concrete on or against concrete which has taken its initial set, the surface of the hardened concrete shall be broken off down to coarse aggregate and wire-brushed to remove foreign matter and laitance. A layer of grout of the same cement-sand ratio as the concrete without coarse aggregate shall be placed to a thickness of 1 to 2 inches on the brushed surface after which the new concrete shall be placed immediately. When concreting has once started, it shall be carried on as a con- tinuous operation until the section or structural unit is completed. All concrete shall be thoroughly compacted by vibrators, spading or other suitable means during the operation of placing, to ensure that concrete will flow around all reinforcement, embedded fixtures and into the corners of the forms to give a dense finished product with true sur- faces free from honeycombing, segregation and other imperfections. ys Concrete shall be placed in horizontal layers of no greater depth than ® 18 inches. Concrete shall be placed at a suitable rate to avoid the forma- tion of unauthorized cold joints. In no case shall vibrators be used to transport the concrete inside the forms. Care shall be taken when placing concrete through reinforcing steel so that the segregation of coarse aggregate is kept to a minimum. In such 111-34 cases, spouts, elephant trunks, or other suitable means shall be used. The free fall of concrete shall be held to a practical minimum and shall not exceed 5 feet at any time. The placing of concrete shall be so planned that horizontal and vertical construction joints are made where shown on the drawings or where approved by the Engineer. Structural keys shown on the Plans shall have a minimum width of 4 inche s and a depth of 1-1/2 inche s. The con- crete shall be lfift with a roughened surface for construction joints. Water- stops shall be placed as shown on the Plans and in all construction joints subject to water on one side and where the opposite side is intended to be dry. q. Tests. The Contractor shall provide for test purposes, one set of four cylinders taken from each day's pour of each class of concrete poured, except that pours of Class B concrete of less than 3 cubic yards need not be tested. The test cylinders shall be made and cured in ac- cordance with ASTM Specification_: C31. Two cylinders shall be broken at 7 days and two cylinders at 28 days in accordance with ASTM Specifi- cation C39. r. Protection. The Contractor shall protect all concrete against injury until final acceptance by the Engineer. During cold weather all concrete materials and all reinforcement, forms, fill material, and ground with which the concrete will be placed in contact, shall be free of frost or ice and snow. Whenever the tempera- ture of the surrounding area is 40 degrees F. and falling, no concrete an shall be placed unless the Contractor has on hand sufficient, suitable, and approved means of protecting the concrete. Whenever the temperature of the surrounding air is between 40 degrees F. and 32 degrees F. , all con- crete placed in the forms shall have a temperature between 50 and 70 de- grees F. Adequate means shall be provided for maintaining a temperature in the surround air not less than 70 degrees F. for at least three days, or 50 degrees F. for five days. The housing, covering, or other protection used shall remain intact and in place at least 24 hours after artificial heat- ing is discontinued. Care must be used to prevent fire hazards when using heating and no fire or excessive heat shall be permitted near or in direct contact with concrete at any time. Salt or chemicals shall not be used in the concrete to. prevent freezing. ® Whenever the temperature of the surrounding air reaches 32 de- grees F. , or lower, concrete shall not be placed except with the approval of the Engineer who shall state the time in addition to that specified herein 111-35 that artificial heat and protection must bb supplied. Whenever the tempera- ture of the surrounding air reaches 20 degrees F. or lower, no concrete shall be placed except for emergencies and only with special permission and supervision of the Engineer. s. Curing of Concrete. All concrete placed when the temperature is above 40 degrees F. shall be either sprinkled continuously for 72 hours, ffA or shall be covered with burlap which shall be kept moist for at least 72 hours. The use of membrane curing shall be permitted only when approved by the Engineer. The membrane curing compound shall be of a type ap- An by the Engineer. Concrete cured-with water shall be kept continually wet for at least 72 hours immediately following placement of the concrete, or until covered with fresh concrete. The concrete to be cured shall be kept wet by cover- ing with water-saturated material or by a system of perforated pipes, mechanical sprinklers, or porous hose, or by any other approved method which will keep all surfaces to be cured continuously (not periodically) wet. Water curing shall commence as soon as the concrete has hardened sufficiently to prevent damage. Water used for curing shall meet the re- quirements for water used for mixing concrete. Membrane curing compound shall be applied to formed surfaces immediately after the forms are removed. If any areas require patching, or any other surface treatment, the membrane curing shall not be applied to that area until after the area has been repaired. The area to be repaired shall be kept continually wet by a method approved by the Engineer prior to the patching or surface treatment of the area. Following the patching or surface treatment and a 24-hour period of water curing, the area may, at the Contractor's option, be treated with membrane curing compound for the remainder of the curing period. Any rriembrane curing compound applied to surfaces that require patching or other surface treatment, or to surfaces that are specified to 'be water cured as listed above, shall be completely removed by sand blasting. Where membrane curing is used, following removal of the forms, the surfaces shall be thoroughly moistened with water and the curing com- pound applied as soon as free water disappears. The curing compound shall be applied to unformed surfaces as soon as free water disappears or immediately following finishing where special finishing operations are specified. The curing compound shall be applied in a two-coat continuous operation by approved power-spraying equipment and at a uniform coverage 111-36 of not more than 300 square feet per gallon for each coat. All concrete surfaces on which the curing compound has been applied, shall be ade- quately protected for a period of 72 hours from any cause which will disrupt the continuity of the curing membrane. Any curing membrane damaged during the 72-hour period, shall be restored as directed by the Engineer. t. Finishing. Immediately after removing the forms, all fins or irregular projections shall be removed from all surfaces. On all surfaces the area of cavities produced by form ties, holes, honeycombing, broken edges or corners, and other surface defects, shall be cleaned and care- fully filled, pointed, and troweled to a true uniform smooth surface with sand-cement mortar mixed in the proportions used in the grade of concrete being furnished. Defective concrete as determined by the Engineer shall be repaired by cutting out the unsatisfactory material and placing new con- crete which shall be secured with keys, dovetails or anchors. Concrete for patching shall be drier than the usual mixture and shall be thoroughly tamped into place. All exposed concrete surfaces, that is, .those surfaces which will be visible after the project is in operation (except floor slabs) shall be finished in following manner: Forms shall be removed from such surfaces as soon as structurally possible, as approved by the Engineer, and all de- pressions or imperfections immediately patched as described above. The surface shall then be machine or hand-rubbed until the entire surface has a smooth, homogeneous pleasant-appearing finish of uniform texture and color. Any delay in patching or rubbing such surfaces shall be cause for rejection of the entire structure or for requiring the surfaces to be ground smooth and painted. No mortar or wet cement shall be used in finishing except the mortar necessary to fill imperfections. Edging tools shall be used on all exposed top edges. Floors shall be brought to a true grade with a straightedge and roughly finished with a wooden float. After the concrete has hardened sufficiently to prevent an excess of fine material working to the top, the surfaces shall be troweled with steel trowels until the surface is smooth and regular. No additional cement shall be added during finishing. All concrete and reinforcing steel shown on the Plans or required by the specifications shall be included in the lump sum contract price bid for each item in which the concrete is used, and will not be measured or paid for separately, except Class B and C concrete used for pipe bedding or pipe encasement and cradling will be measured and paid for as noted elsewhere in these specifications. III-37. Should any changes or additions to the Contract require any changes in the amount of formed concrete or reinforcing steel to be provided by the Contractor, the unit prices for formed concrete and reinforcing steel stated in the Contract Agreement shall be used to determine the amount to be added to or to be deducted from the contract lump sum price for the item involved. The volume of concrete to be paid for shall be determined by the required dimensions for the formed concrete provided to the Contractor by the Engineer. The weight of steel to be paid for shall be determined by the actual weight of reinforcing steel. installed. The unit price for formed concrete shall include all materials, forms, mixing, placing, curing, finishing and all other costs incident thereto. The unit price for reinforcing steel shall include all material and labor and all other costs incident thereto. 28. GROUTING: Grout placed against hardened concrete prior to placing fresh con- crete shall not contain an expansion material. Grout used to set equipment, fill in around pipes through concrete walls, and in all other locations directed by the Engineer (except as specifi- cally noted otherwise above) shall contain an expansion agent. WIN Grout without an expansion agent shall consist of the same propor- tions of materials as used for Class A concrete, except without the coarse aggregate. Grout with an expansion agent shall consist of two parts dement to three parts sand. Embecco shall be added in the amount and by the method recommended by the manufacturer; unpolished aluminum powder shall be added at the rate of one level teaspoon per sack of cement. The aluminum powder shall be added to the sand and cement after they have been mixed dry. Only sufficient water shall be added to make the mix workable. Grout with the expansion agent shall be carefully placed to completely fill the space being grouted. The grout shall be packed into the space using caulking tools to fill the space and make a dense finished grout. 111-38 MMIIII !IIION MUM l The cost of all work described in this paragraph shall be included in the lump sum price bid for the items in which the work is to be in- corporated. 29. INSTALLATION OF WATERSTOPS: PVC or rubber waterstops shall be provided where shown on the Plans. All waterstops shall be placed to provide a continuous barrier to the flow of water across a joint in the concrete structure and shall be in- stalled in strict conformance to the recommendations of the manufacturer. PVC waterstops shall be attached to the forms with double headed nails at approximately 6-inch centers so that the waterstop is held flat against the form. PVC waterstops shall be spliced with heat. Prefabri- cated fittings shall be used and only butt joints made in the field. All jointing shall be done by skilled, experienced workmen. Rubber waterstops shall be securely fastened to forms in such position that one bulb will be embedded in each of two adjoining slabs or walls. Center bulbs shall be placed in the joint. Lengths of rubber water- stops shall be joined with rubber cement or by vulcanizing so that the waterstop is continuous and watertight when installed. Prefabricated fittings shall be used. All jointing shall be done by skilled, experienced workmen.

Expansion shields shall be installed in strict accordance with the manufacturer's instructions. The cost of all work described in this paragraph shall be included in the lump sum price bid for the item in which the work is to be incorporated. 31. HANDLING AND ERECTION OF STRUCTURAL STEEL: All structural steel received on the work shall be immediately placed upon substantial shores or blocking of sufficient size and strength to prevent any metal from touching the ground, and in such a manner that water cannot collect thereon and so that the material will be protected 111-39 against bending under its own or superimposed loads. Any steel members which may become bent shall be replaced by new material. Before assem- bling, the surfaces to be in contact with each other shall be thoroughly cleaned. Base plates shall be set level and in exact position and grouted in place. The grout shall completely fill the space beneath the base plates. All parts shall be assembled accurately as shown on the Plans and all match marks shall be followed carefully. Light drifting will be per- mitted to draw the parts together, but drifting to match unfair holes will not be permitted. Any enlargements of holes necessary to make connec- tions in the field shall be done by reaming with twist drills, care being taken not to weaken the adjoining metal. If, in the opinion of the Engineer, the extent of the reaming is such that the holes cannot be properly filled or accurately adjusted after ream- ing, the faulty member shall be discarded and replaced by a new one. All field connections shall be bolted. Nuts shall be drawn tight and the threads burred to prevent loosening. Unfinished bolts may be used for field connections. The cost of all work described in this paragraph shall be included in the lump sum price bid for the item in which the work is to be incorporated. ga yff 32. CONSTRUCTION OF SERVICE DRIVES: General. Service drives shall be constructed to the lines and grades shown on the Plans. Service drives shall consist of a 6-inch thick macadam base treated with oil. Methods of construction in conformity with the applicable current Standard Specifications of the Missouri State Highway Commission and in general conformance with the following specifications may be used if ap- proved by the Engineer. After the wearing surface has been placed, no vehicles will be per- mitted to use the drive for parking, delivery of materials, etc. Any damage to the base course prior to the placing of the wearing surface shall be repaired to the satisfaction of the Engineer. Preparation of Subgrade. The area for the proposed service drives shall be excavated or filled as required to provide a finished wearing III-40 surface to the elevations shown on the Plans. The area shall be rolled and compacted to the satisfaction of the Engineer. All soft and yielding spots shall be removed to a depth of not to exceed 2 feet, and all vegetable substances or unsuitable material shall be removed, and the resulting spaces shall be refilled with approved stable material. The subgrade shall again be rolled until no depressions occur. Construction of Macadam Base Course. After the subgrade has been properly prepared, new, clean, crushed stone shall be used to build up the base to the necessary thickness. After the coarse aggregate has been spread and shaped, it shall have a uniform distribution of sizes throughout and shall contain no dirt or any other foreign substances. The coarse aggregate shall then be rolled and compacted until it is well keyed and all settlement has ceased. The surface shall then be checked trans- versely with a template cut to the required cross section and longitudinally with a 20-foot straightedge. Any indicated variations exceeding 1Y2 inch shall be corrected by the removal or addition of coarse aggregate as re- quired. Corrected areas shall be compacted and made to conform with the required grade and cross section. After the surface has been checked and any necessary corrections made, screenings shall be gradually and uniformly applied to the surface in successive thin applications by means of approved mechanical spreaders. Under no condition shall screenings be dumped in piles on the coarse ag- gregate. If the screenings are in a. damp or wet condition, they shall not be rolled, vibrated nor broomed until the surface particles have dried. The application of screenings shall continue until all voids in the coarse aggregate are filled. Any excess screenings remaining shall be swept from the surface before water is applied. During the application of screenings, compaction shall continue so the jarring effect of the roller will cause the dry screenings to fall into and fill the voids in the coarse aggregate. As a further aid in filling inter- stices, the screenings shall be swept into the voids by hand or mechanical means, or both. In no case shall the screenings be allowed to "cake" or bridge on the surface in any manner that would prevent filling the voids or prevent the roller from having direct bearing on the coarse aggregate. When screening trucks are being driven on the partially completed surface, care shall be taken not to disturb the coarse aggregate. These da trucks shall not be driven over the unfilled coarse aggregate except for the distance necessary during the spreading operations. If at any time the surface is harmfully disturbed, such disturbed area shall be removed and corrections made in compliance with this specification. III-41 After spreading of screenings and dry compaction is complete, the surface shall be checked longitudinally with a 20-foot straightedge. In- dicated variations of more than 1/2 inch shall be corrected to conform with the required grade and cross section. The surface shall then be sprinkled and rolled. If voids still remain, they shall be filled by sweep- ing screenings into them. Sprinkling, sweeping and compacting shall continue until a grout is formed sufficient to fill all voids and form a wave of grout before the roller. The amount of grout shall be sufficient only to produce a final mosaic, granular surface. If necessary to secure a well bonded surface, the macadam shall be kept wet for at least 48 hours, or longer, before final compaction. Should the subgrade become soft and mixed into or through the macadam, the Contractor shall remove the mixture, reshape and correct the subgrade, replace the removed materials and waterbind the corrected area in compliance with this specification. The completed waterbound macadam base shall have a total com- pacted thickness of not less than 6 inches. The surface will not vary more than 1/2 inch from grade by a 20- foot straightedge applied to the surface parallel to the centerline of the pavement. Areas of the base which show more than the allowable variation shall be loosened and reconstructed in accordance with these specifications and to the complete satisfaction of the Engineer. Construction of Oiled Surfaces. The finished macadam base course shall be treated with one application 0. 2 to 0. 3 gallons per square yard of Type MC-0 Liquid Asphaltic Material or other material in con- fur*).ity with the applicable current specifications of the Missouri State Highway Commission. Blotter Course. A blotter course of limestone screenings shall be placed after the application of oil to the macadam base. Payment.
