I am writing to formally submit a revised price proposal for the Sesame Street Culvert Replacement between NW 135th St. & Atlantic Ave (RFP NO: 23- 1016200) bid, which was previously tendered to your office on September 17,2023. I appreciate the opportunity to participate in this bid, and after careful consideration and further evaluation, I believe that the revised proposal will better align with the needs and expectations of our esteemed city. Upon a thorough review of the project requirements, as well as discussions with city officials (Microsoft Teams meeting -Tuesday, October 31, 2023, 9:30 AM -10:00 AM) and with my team, and careful analysis of our cast estimates, I have identified several areas where we can offer a more competitive and cost- effective proposal without compromising the quality or integrity of our work. Our commitment to delivering value to the city remains unwavering, and we believe that the revisions we have made will better reflect our dedication to your community. To facilitate a clear understanding of the changes we have made, we have prepared a detailed Item -by - item comparison between the original and revised price proposals.

LLC SAFA CONSTRUCTION, LLC Phone: (954) 326-8295 Email: md.rahman@safaconstruction.net Note for revisions in our proposal: 1) In the original bid, there was no separate line item for Bonding cost, so bonding cost was included in line item number 16, and in the revised price proposal bonding cost is shown separately in item number 26-A for clarification. 2) During the re -site visit to the construction site, we identified that unsuitable material in the canal would not be that much. 3) We feel that We do not police guard during construction. I halve been working with the city past 10 years, I ne)rer felt that I needed a police guard to work in tlhe city. So, the cost Is deleted. 4) This is the city's project within its own city limit. So, the city can handle this issue internally as it was done for other projects. 5) Unforeseen conditions are unpredictable and non -measurable. The city can keep the cost for this line Item internally as it was for other standard projects. In this comparison table, we have outlined the specific Items, their descriptions, the original pricing, the revised pricing, and the cost savings achieved in the revised proposal. We believe this breakdown provides transparency and demonstrates our commitment to offering the best value for the city. We are confident that the revised proposal reflects our dedication to delivering a competitive and cost- effective solution for the city. Our team remains fully committed to collaborating closely with your office to ensure the successful execution of this project, should our proposal be accepted. If you have any questions or require further clarification regarding the itemized comparison or any other aspects of the proposal, please feel free to contact me directly at 5954) 326-8295 or via email at md.rahman@safaconstruction.net . We are eager to engage in discussions and provide any additional information or documentation as needed. We would like to express our sincere gratitude for your consideration of our proposal and for your dedication to selecting the best value for the city. We are enthusiastic about the opportunity to contribute to the continued growth and development of our community and look forward to the possibility of working closely with your office to realize this vision.

Pavement markings removed or obliterated by the Contractor's operations shall be promptly replaced, in kind, to the satisfaction of the City of Opa-Locka Department of Public Works, Traffic Engineering Division or designee. 2-41 AveStreet City of Opa-Locka Sesame to St. & Atlantic Culvert Replacement Between NW 135 2. At least three density determinations shall be made on each day's final compaction operations on each course, and the density determinations shall be made at more frequent intervals if deemed necessary by the City or designee. B. Subbase: Roadway subbase shall be stabilized to the minimum depth shown on the Drawings to a LBR not less than 40. Stabilizing shall be type C as defined in Section 160 of the FDOT specifications. Stabilization may require the addition and thorough mixing in of crushed limerock, coarse limerock screenings, or any other stabilizing material acceptable to the City or designee. The stabilizing material shall be applied in such quantity that, after mixing and blending, the subbase will have a LBR not less than 40. Stabilizing material shall be mixed or blended in the subbase material by plowing, scarifying, disking, harrowing, blading, and mixing with rotary tillers until the mixed materials are of uniform bearing ratio throughout the width and depth of the layer being processed. The minimum acceptable density at any location will be 98% of maximum dry density as determined by AASHTO T-180. C. Limerock Base: The limerock base shall be constructed in accordance with Section 200 of the FDOT Specifications, to the thickness and width indicated on the Drawings. Pavement base shall be constructed in maximum 6 -inch lifts. D. After spreading of the base material is completed, the entire surface shall be scarified and shaped so as to produce the exact grade and cross section after compaction. For double course base, this scarifying shall extend a depth sufficient to penetrate slightly the surface of the first course. The maximum depth of each lift shall be 6 -inches. E. When the material does not have the proper moisture content to ensure the required density, wetting or drying shall be required. If the material is deficient in moisture, water will be added and uniformly mixed in by disking the base course to its full depth. If the material contains an excess of moisture, it shall be allowed to dry before being compacted. Wetting and drying operations shall involve manipulation of the entire width and depth of the base as a unit. As soon as proper conditions of moisture are attained, the material shall be compacted to an average density not less than 98% of maximum dry density as determined by AASHTO T-180. Where the base is being constructed in more than one course, the density shall be obtained in each lift of the base. F. During final compacting operations, if blading of any areas is necessary to obtain the true grade and cross section, the compacting operations for such areas shall be completed prior to making the density determination on the finished base. G. Unless otherwise directed by the City or designee, the surface shall be "hard -planed" with a blade grader immediately prior to the application of the prime coat to remove the thin glaze or cemented surface and to allow free penetration of the prime material. The materials planed from the base shall be removed from the base area. 2-42 AveStreet City of Opa-Locka Sesame to St. & Atlantic Culvert Replacement Between NW 135 H. If cracks or checks appear in the base, either before or after priming, which in the opinion of the City or designee, would impair the structural efficiency of the base course, the Contractor shall remove such cracks or checks by re -clarifying, reshaping, adding base material where necessary and re -compacting, at no additional cost to the City or Owner. I. Mixing Base and Subbase: If at any time the subbase material shall become mixed with the base course material, the Contractor shall, without additional compensation, dig out and remove the mixture, reshape and compact the subbase and replace the materials removed with clean base material, which shall be shaped and compacted as specified above. J. Prime Coat: The prime coat shall be applied at a rate of 0.15 gallons per square yard and the work performed in accordance with Section 300 of the FDOT Specifications. K.

Connections with Existing Facilities Where the bituminous pavement is to be connected with an existing roadway surface or other facility, the Contractor shall modify the existing roadway profile in such a manner as to produce a smooth riding connection to the existing facility. Where it is necessary to remove existing asphalt surfaces to provide proper meet lines and riding surfaces, the Contractor shall saw cut the existing surface so that there will be sufficient depth to provide a minimum of 1 inch of asphalt concrete, and the waste material shall be disposed of to the satisfaction of the City or designee. Prior to placing the asphalt concrete, these areas shall be tacked. Meet lines shall be straight and the edges vertical. The edges of meet line cuts shall be painted with liquid asphalt or emulsified asphalt prior to placing asphalt concrete. After placing the asphalt concrete, the meet line shall be sealed by painting with a liquid asphalt or emulsified asphalt and immediately covered with clean, dry sand. N. Surface Tolerance 1. Tests for conformity with the specified grade shall be made immediately after initial compression. Any variation shall be immediately corrected by the removal or addition of materials and by continuous rolling. The completed surface of the pavement shall be of uniform texture, smooth, uniform as to grade, and free from defects of all kinds. 2-43 AveStreet City of Opa-Locka Sesame th St. & Atlantic Culvert Replacement Between NW 135 2. The completed surface shall not vary more than 1/8 inch from the lower edge of a 12 -foot straightedge placed on the surface along the centerline or across the trench. 3. After completion of the final rolling, the smoothness and grade of the surface shall again be tested by the Contractor. 4. When deviations in excess of the above tolerances are found, the pavement surface shall be corrected as stated in Section 330-12.4 of the FDOT Specifications. 5. All areas in which the surface of the completed pavement deviates more than twice the allowable tolerances described above shall be removed and replaced to the satisfaction of the City or designee. O. Weather Conditions: Asphalt shall not be applied to wet material. Asphalt shall not be applied during rainfall or any imminent storms that might adversely affect the construction. The Engineer will determine when surfaces and materials are dry enough to proceed with construction. Asphalt concrete shall not be placed during heavy rainfall or when the surface upon which it is to be placed is wet. P. Protection of Structures and Adjustment of Appurtenances 1. Provide whatever protective coverings may be necessary to protect the exposed portions of bridges, culverts, curbs, gutters, posts, guard fences, road signs, and any other structures from splashing oil and asphalt from the paving operations. Remove any oil, asphalt, dirt, or any other undesirable matter that may come upon these structures by reason of the paving operations. 2. Where water valve boxes, manholes, catch basins, or other underground utility appurtenances are within the area to be surfaced, the Contractor shall adjust the covers of these improvements to conform to the proposed surface elevations. 3. In this effort, the Contractor shall be responsible for ensuring that appurtenances are brought to proper grade to conform to the finished surface elevations and any delays experienced from such obstructions will be considered as incidental to the paving operation. No additional payment will be made. Protect all covers during asphalt application. Q. Pavement Warranty: Settlement of replaced pavement over trenches within the warranty period shall be considered the result of improper or inadequate compaction of the subbase or base materials. The Contractor shall promptly repair all pavement deficiencies noted during the warranty period at the Contractor's sole expense. 2-44 AveStreet City of Opa-Locka Sesame th St. & Atlantic Culvert Replacement Between NW 135 R. The pressure distributor used for placing the tack or prime coat shall be equipped with pneumatic tires having sufficient width of rubber in contact with the road surface to avoid breaking the bond of or forming a rut in the surface. The distance between the centers of openings of the outside nozzles of the spray bar shall be equal to the width of the application required, within an allowable variation of 2 -inches. The outside nozzle at each end of the spray bar shall have an area of opening of not less than 25 percent, nor more than 75 percent in excess of the other nozzles which shall have uniform openings. When the application covers less than the full width, the normal opening of the end nozzle at the conjunction line may remain the same as those of the interior nozzles. S. Application Temperatures: For asphalt cement Viscosity Grade AC -5, the application temperature shall be between 300 degree and 350 degree F; for emulsified asphalt, between 100 degrees and 170 degrees F; and for cut -back asphalt, between 175 degree and 275 degree F.310-9.3 Uniformity of Distribution: Special precautions shall be observed to assure that an even and uniform distribution of bituminous material will be obtained, and the distributor shall be so adjusted and operated as to maintain uniform, even distribution of the type of material being applied. Excessive deposits of bituminous material upon the road surface caused by stopping or starting the distributor, by leakage or otherwise, shall be immediately removed. T. When the prime or tack coat is applied adjacent to curb and gutter, or any other concrete or special pavement surface (except where they are to be covered with a bituminous wearing course) such concrete surfaces shall be protected by heavy paper or other protective material while the prime or tack coat is being applied. Any bituminous material deposited on such concrete surfaces shall be removed immediately. U. No bituminous material shall be applied when the air temperature is less than 50 degree in the shade, or when the weather conditions or the condition of the existing surface is unsuitable. In no case shall bituminous material be applied while rain is falling or when there is water on the surface to be covered. V. After the base has been finished, the full width of surface shall be swept with a power broom supplemented with hand brooms and mechanical blowers prior to the application of the prime coat. Care shall be taken to remove all loose dust, dirt and objectionable matter. If deemed necessary, the base shall be lightly sprinkled with water immediately in advance of the prime coat. The prim coat shall be applied to the full width of the base. W. The temperature of the prime material shall be such as to insure uniform distribution. The material shall be applied with a pressure distributor as specified above. The amount to be applied shall be sufficient to coat the surface thoroughly and uniformly without any excess to form pools or to flow off the base. For lime rock base, the rate of application shall not be less than 0.10 gallons per square yard. 2-45 AveStreet City of Opa-Locka Sesame th St. & Atlantic Culvert Replacement Between NW 135 X. The roadway may be opened for use following the application of the prime material, and a light uniform application of clean sand shall be applied and rolled. The sand shall be non -plastic, shall be free from silt rock particles and shall not contain any sticks, vegetation, grass, roots or organic matter. After the sand covering has been applied, the surface will be opened to traffic. Y. Asphalt Densities: The in place density of each course of asphalt mix construction, with the exceptions of patching courses, leveling and intermediate course less than one -inch thick or a specified spread rate less than 100 pounds per square yard, overbuild courses where the minimum thickness is less than one -inch, and opengraded friction course, shall be determined by the use of the Nuclear Density Backscatter Methods as specified by FM 1-T238 (method B).

PART 3 — EXECUTION 3.0.1. INSTALLATION OF ROADWAY MATERIALS A. Subgrade: The work shall consist of bringing the bottom of the excavations and the top of the embankments of the roadways between the outer limits of the roadway to a surface conforming to the lines, grades, and cross sections shown on the plans, of uniform required density, ready to receive the base or paving course. The final elevation of the subgrade shall be within 0.1 foot of the required elevation. 2-56 AveStreet City of Opa-Locka Sesame to St. & Atlantic Culvert Replacement Between NW 135 1. All submerged stumps, roots, and other unsuitable matter encountered in the preparation of the subgrade shall be removed and replaced with a suitable material. 2. The material in the top 12" of subgrade shall have a minimum CBR of 25 when compacted to 95% of maximum density as determined by AASHTO Specification T 180-74. In areas such a condition does not exist, the top 12" of subgrade shall be stabilized as described below: 3. Stabilizing Material: Where stabilized subgrade and shoulders are required, the subgrade and shoulder material shall have a minimum California Bearing Ratio Material Value not less than 25. If the in place subgrade or shoulder material has a CBR value less than 25, a suitable stabilizing material shall be added. Such stabilizing material shall be crushed lime rock, coarse lime rock screenings, or any other stabilizing material approved by the Engineer. 4. Suitable stabilizing materials obtained from an existing base or pavement which is to be replaced or abandoned may be used providing that such material contain no fragments larger than 3'/ inches in diameter. 5. The entire subgrade, including 2 feet beyond the edge of the proposed pavement, shall be thoroughly plowed, scarified, and mixed to a depth of not less than 6 inches below grade. All pot holes and other irregularities shall be filled with suitable material or trimmed down as the case may be, prior to compacting. If the area is cut to grade in natural lime rock, the top 6 inches shall be thoroughly plowed, scarified, and mixed. This plowed, scarified, and mixed layer shall be compacted to not less than 95 percent of the maximum density as determined by AASHTO Specifications T 180-74 prior to the placement of the base course. 6. After the subgrade has been prepared as specified above, the Contractor shall maintain it free from ruts, depressions, and damage resulting from the hauling and handling of any material, equipment, tools, etc. Ditches or drains shall be constructed and maintained along the completed subgrade section. Just before the base course is laid, the subgrade shall be tested as to, elevation and density. B. Transporting Lime rock: The lime rock shall be transported to the point where it is to be used, over rock previously placed if practicable, and dumped on the end of the preceding spread. No hauling over the subgrade or dumping on the subgrade shall be done C. Spreading Lime rock: 1. When using new material, the lime rock shall be spread uniformly, and all segregated areas of fine or coarse rock shall be removed and replaced with wellgrade rock. 2-57 AveStreet City of Opa-Locke Sesame th St. & Atlantic Culvert Replacement Between NW 135 2. When the specified compacted thickness of the base is greater than 6 -inches, the base shall be constructed in two courses. The thickness of the first course shall be approximately one-half the total thickness of the finished base, or enough additional to bear the weight of the construction equipment without disturbing the subgrade. 3. When using the existing base material, the Contractor shall expose the existing base material to the final base grade shown on the drawings. The Contractor shall then proceed with scarifying the top 6 inches of the base and reworking and compacting the material to achieve the required cross-section. 4. Minimum longitudinal slope shall be 0.3% for all roadways. For roadways with gutters, the longitudinal slope may be reduced upon approval by the Public Works Department. D. Compacting and Finishing Base: 1. General: a. For single course base, after spreading is completed, the entire surface shall be scarified and then shaped so as to produce the required grade and cross section after compacting. b. For multi lift base course, the first course shall be four (4) inches thick compacted cleaned of foreign material, bladed and brought to a surface cross section approximately parallel to that of the finished base. Prior to the spreading of any material for the upper course, the density test for the lower course shall be made and the Engineer shall have determined that the required compacting has been obtained. After the spreading of material for the second course is completed, its surface shall be finished and shaped so as to produce the required grade and cross section after compacting and free of scab and laminations. 2. Moisture Content: When the material does not have the proper moisture content to insure the required density, wetting or drying will be required. If the material is deficient in moisture, water shall be added and uniformly mixed in by discing the base course to its full depth. If the material contains an excess of moisture, such excess shall be reduced or removed until the required moisture content is attained before being compacted. Wetting or drying operations shall involve manipulation of the entire width and depth of the base as a unit. 3. Density Requirements: As soon as proper conditions of moisture are attained, the material shall be compacted to a density of not less than 98 percent of the 2-58 AveStreet City of Opa-Locka Sesame th St. & Atlantic Culvert Replacement Between NW 135 maximum density as determined by AASHTO Designation T-180 as described below: a. During final compacting operations, if blading of any areas is necessary to obtain the true grade and cross section, the compacting operations for such areas shall be completed prior to making the density determinations on the finished base. b. At least three density determinations shall be made at the completion of each course, also the density determinations shall be made at new/replaced every utility crossings and also at every 7,000 square feet of roadways or at more frequent intervals if deemed necessary by the Engineer. 4. Correction of Defects: a. If at any time the subgrade material should become mixed with the base course material, the Contractor shall dig out and remove the mixture, reshape and compact the subgrade and replace the materials removed with clean base material, which shall be shaped and compacted as specified above. b. If cracks or checks appear in the base, either before or after priming, which in the opinion of the Engineer would impair the structural efficiency of the base course, the Contractor shall remove such cracks or check by re -scarifying, reshaping, adding base material where necessary and recompacting. E. Testing Surface: The finished surface of the base course shall be checked with a templet cut to required crown and cross section and with a 10 -foot straightedge laid parallel to the centerline of the road. All irregularities greater than 1/4 -inch shall be corrected by scarifying and removing or adding lime rock as may be required, after which the entire area shall be recompacted as specified herein before. F. Thickness Determinations: 2-59 AveStreet City of Opa-Locka Sesame th St. & Atlantic Culvert Replacement Between NW 135 The thickness of the compacted lime rock base shall be measured at intervals of not more than 200 -feet. Measurements shall be taken at various points on the cross sections prior to the application of the prime coat. 2. The measurements shall be taken in holes through the base of not less than 3inches in diameter. Where the compacted base is deficient by more than 1/2 -inch from the thickness called for on the drawings, the Contractor shall correct such areas by scarifying and adding lime rock. The base shall be scarified and rock added for a distance of 100 -feet in each direction from the edge of the deficient area. The affected areas shall then be brought to the required state of compaction and to the required thickness and cross section. G. Priming and Maintaining: 1. The prime coat shall be applied only when the base meets the specified density requirements and the moisture content in the top half of the base does not exceed 90 percent of the optimum moisture content of the base material. At the time of priming, the base shall be firm and unyielding. 2. The Contractor will be responsible for assuring that the true crown and grade are maintained with no rutting or other distortion and that the base meets all the requirements at the time the surface course is applied. 3.0.2. INSTALLATION OF CONCRETE A. The concrete shall be placed on stabilizing or compacted subgrade to such depth that, when it is consolidated and finished, the slab thickness required by the drawings will be obtained at all points and surface will at no point be below the grade specified for the finished surface, after application of the allowable tolerance. The concrete shall be deposited on the stabilized subgrade in a manner which will require as little rehandling as possible. Placing of the concrete shall be continuous between transverse joints, without the use of intermediate bulkheads. B. Steel reinforcement is called for on the drawings shall be placed at mid slab depth and the fabric shall be maintained at this location during the placing and finishing operations. C. Concrete shall be thoroughly consolidated against and along the faces of all forms, and along the full length and on both sides of all joint assemblies, by means of hand operated, vibrators. Vibrators shall not be permitted to come in contact with joint assembly, the subgrade or a side form. Vibration at any one location shall not continue so long as to produce puddling or the accumulation of excessive grout on the surface. In no case shall the vibrator be operated longer than 15 seconds in any one location. 2-60 AveStreet City of Opa-Locka Sesame th St. & Atlantic Culvert Replacement Between NW 135 1. D. Coloring of concrete shall be done by dry -mixing the compound and broadcasting over the fresh -poured concrete after it has been struck off. E. Striking off, Consolidating and Finishing Concrete: 1. Immediately after the placing, the concrete shall be struck off, consolidated and finished, to produce a finished pavement conforming to the cross section, width and surface finish required by the drawings and specifications. The sequence of operations shall be as follows: strike -off; vibratory consolidation; screeding; floating; removal of laitance; straight edging; and final surface finish. Strike -off, consolidation and finishing shall be accomplished in a manner such as to avoid damage to, or misalignment of, joint assemblies, dowels and other embedded items. F. Straight edging and Surface Correction: 1. After floating has been completed and the excess water removed, but while the concrete is still in a plastic state, the surface of the concrete shall be tested for trueness with an accurate 10 -foot straightedge. The straightedge shall be furnished by the Contractor. The straightedge shall be held in successive positions parallel to the road center line, in contact with the surface, and the whole area tested from one side of the slab to the other as necessary. The advance along the road shall be in successive stages of not more than one-half the length of the straightedge. Any depressions shall be immediately filled with freshly mixed concrete and struck -off, consolidated and refinished. High areas shall be cut down and refinished. Straightedge testing and surface correction shall continue until the entire surface appears to conform to the required grade and cross section. 2. As soon as the concrete has hardened sufficiently to be walked on, straight edging shall again be done. All surface irregularities exceeding 14 -inch in a 10 -foot shall be corrected by grinding as directed by the Engineer. G. Final Finish: As soon as the water sheen has disappeared from the surface of the pavement and just before the concrete becomes non -plastic, a light broom finish shall be given to the surface. H. Edging: 1. After the final finish has been applied, but before the concrete has become nonplastic, the edge of the pavement along each side of the strip being placed, on each side of transverse and longitudinal contraction joints and construction joints and along structure extending into the pavement, shall be carefully rounded to a '/-inch radius except as otherwise indicated. A well-defined and continuous radius shall be produced and a smooth, dense mortar finish obtained. All concrete shall be completely removed from the top of the joint filler. 2-61 AveStreet City of Opa-Locka Sesame th St. & Atlantic Culvert Replacement Between NW 135 2. All joints shall be checked with a straightedge before the concrete has become non -plastic and, if one side of the joint is higher than the other or the entire joints is higher or lower than the adjacent slabs, corrections shall be made as necessary. I. Joints: Transverse Construction Joints: Transverse construction joints shall be constructed at the end of all pours and at other locations where the paving operations are stopped for as long as 30 minutes.

If, in lieu of a single gasket spanning the joint, two gaskets are used, place these individual gaskets approximately 2 inches from each pipe end at the joint. When two gaskets are used, seal the overlapping area on the coupling band between the gaskets consistent with the joint performance specified. The Contractor may tuck a strip of preformed gasket material over the bottom lip of the band for this purpose. Use coupling bands that provide a minimum circumferential overlap of 3 inches. As the end connections on the coupling band are tightened, ensure that there is no local bending of the band or the connection. Use precurved coupling bands on pipe diameters of 24 inches or less. D. Use flat gaskets meeting the requirements of ASTM D1056, designation 2C2 or 2B3. In placing flat gaskets on pipe prior to placing the coupling band, do not stretch the gasket more than 15% of its original circumference. Use circular gaskets meeting the requirements of ASTM C361. Do not stretch the circular gasket more than 20% of its original circumference in placing the gasket on pipe. E. Apply an approved vegetable soap lubricant. F. In lieu of the above -specified combination of locking bands and flat gaskets, the Contractor may make field joints for these pipe installations by the following combinations: 1. Use the metal bands as specified in Article 9 of AASHTO M36M that are at least 10-1/2 inches wide and consist of a flat central section with a 2-75 AveStreet City of Opa-Locka Sesame th St. & Atlantic Culvert Replacement Between NW 135 corrugated section near each end, designed to match the annular corrugation in the pipe with which they are to be used. Connect the bands in a manner approved by the Engineer, with a suitable fastening device such as the use of two galvanized 1/2 -inch diameter bolts through a galvanized bar and galvanized strap, suitably welded to the band. Use a strap that is the same gage as the band. Where helically corrugated pipe is to be jointed by this alternate combination, ensure that at least the last two corrugations of each pipe section are annular, and designed such that the band will engage each pipe end with the next -to -outside annular corrugation. 2. For these bands, use a rubber gasket with a circular cross-section of the "0 -ring" type conforming to ASTM C361. Use gaskets having the following cross-sectional diameter for the given size of pipe: Pipe Size Gasket Diameter 12 inches through 36 inches (with 1/2 -inch depth corrugations) 13/16 inch 42 inches through 96 inches (with 1/2 -inch depth corrugations) 7/8 inch 36 inches through 120 inches (with 1 inch depth corrugations) 1-3/8 inches 3. Use channel band couplers in helical pipe with ends which have been reformed and flanged specifically to receive these bands. Use channel band couplers that are of a two-piece design, are fabricated from galvanized steel stock conforming to AASHTO M36, have 2 inch by 2 inch by 3/16 inch angles fastened to the band ends to allow for proper tightening, and meet the following: Band Thickness Pipe Wall Thickness 0.079 inch 0.109 inch or lighter 0.109 inch 0.138 inch or heavier 3/4 inch wide 0.109 inch or lighter One inch wide 0.138 inch or heavier G. Furnish two 1/2 -inch diameter connection bolts with each band, that conform to ASTM A307, Grade A and are electroplated in accordance with ASTM B633. 2-76 AveStreet City of Opa-Locka Sesame th St. & Atlantic Culvert Replacement Between NW 135 H. Use a gasket with the joint that is a hydrocarbon blend of butyl rubber meeting the chemical composition and physical properties of 942-2.2. Use a 3/8 by 3/4 -inch gasket for pipe fabricated from 0.109 inch or lighter material and a 3/8 by 1 inch gasket for pipe fabricated from 0.138 inch and heavier material. I. The Contractor may use a flange band coupler without the gasket for all applications other than side drain, storm and cross drain, and gutter drain. J. Do not use the flange band coupler to join dissimilar types of pipes. K. The Contractor may join reformed flanged helical pipe to existing annular or reformed pipe having annular ends. On non-gasketed installations, use either an annular band or an alternate joint. On gasketed installations, use an annular band, minimum of five corrugations in width, in conjunction with two 0 -ring gaskets. Use mastic material to seal the area of band overlap. L. Install pipe using either a trench or open ditch procedure. M. Check pipe shape regularly during backfilling to verify acceptability of the construction method used. Pipe deflected 5% or more of the certified actual mean diameter of the pipe at final inspection shall be replaced at no cost to the City. Deflection measurements are taken at the point of smallest diameter on the corrugations.

On Public Works roads asphaltic concrete shall have a compacted thickness of 2 -inch, placed in a minimum of two (2) compacted 1 -inch lifts. B. Limerock for pavement base shall be Miami limerock obtained from local sources where the overburden was removed from the pits prior to mining operations. The limerock shall comply with the requirements of FDOT Specifications, Section 911. C. The backfill previously placed and compacted shall be excavated to the required depth below the existing road surface and the existing paving shall be cut back beyond all excavations, using an abrasive disc saw to trim the edges to straight and true lines, minimum width for the lime rock base shall be equal to the trench width plus 2 feet. Eight inches of lime rock base shall be placed in two layers, each layer compacted to not less than ninety-eight percent (98%) density in accordance with Section 200 of FDOT Specifications. During rolling, the base shall be wetted down, as necessary, to secure the greatest possible compaction. After rolling, the entire surface of the base shall be thoroughly scarified to a depth of not less than 3 inches and shaped to conform to and be parallel with the existing surface, then watered and rolled again. Rolling and watering shall continue until the entire depth of the base is bonded and compacted into an unyielding mass. D. If at any time the subgrade material becomes mixed with the lime rock base course materials, the Contractor shall, without additional compensation, dig out and remove the mixture, reshape and compact the subgrade and replace the materials removed with clean rock which shall be watered and rolled until satisfactorily compacted. E. After the lime rock base course has been properly prepared and is dry and ready to receive the wearing surface, a tack coat of emulsified asphalt, in accordance with Section 02741, shall be applied at a rate of 0.10 gallon per square yard, immediately followed by the asphaltic concrete. The tack coat shall be applied to the entire lime rock base uniformly, and shall thoroughly coat all surfaced. Care shall be taken to tack coat and bond the edge of surrounding pavement. F. The asphaltic concrete shall be plant mixed, using the best grade of local aggregates of approved size and gradation and mixed with an approved binder and conforming the either the State of Florida Department of Transportation Specifications, Type S-1 Asphaltic Concrete, Sections 330, 331 and 916 of FDOT Specifications, or Miami Dade County Public Works Type I, as ordered by the Engineer of Record. 2-84 AveStreet City of Opa-Locka Sesame in St. & Atlantic Culvert Replacement Between NW 135 G. Where the width of the repair permits, the asphaltic concrete plant mix material shall be placed by means of an approved mechanical spreader and finisher. The mixture shall be compacted to true grade and cross section by means of a tandem roller weighing not less than eight tons. The compacted asphaltic concrete mixture shall not be, in any case, less than one inch in thickness. Rolling shall proceed as closely behind the spreader as possible and all material shall be completely compacted the same day it is placed. The minimum width of the wearing surface shall be the same as the base. 3.0.4. TYPE IV PAVING REPAIRS (CONCRETE SLAB — RIGID PAVEMENT) A. Type IV repairs will be used when the restoration work falls within the limits of existing rigid pavement. B. Paving repairs shall be similar to Type III paving repairs except that No. 4 reinforcing steel bars spaced 12 inches on centers both ways shall be substituted for the mesh reinforcement, and the slab shall be 8 inches thick instead of 6 inches, with the top of the concrete matching the elevation and finish of the existing pavement. The asphaltic concrete surface course is not required. 3.0.5. TYPE V PAVING REPAIRS (ASPHALTIC CONCRETE WEARING SURFACE OVERLAY) A. Type V paving repairs shall be made where noted on the plans and/or as ordered by the Engineer or Record. Type V paving repairs shall consist of a machine -laid asphaltic concrete wearing surface overlay, which shall be a nominal one -inch thick asphaltic concrete, meeting the material requirements of Type I repairs, as specified hereinabove. As used herein, "overlay" shall mean Type V paving repairs. A special wearing surface may be substituted, if required. B. In general, the overlay shall be applied in a full lane width or widths, after the permanent paving repairs over the trench have been made. Type V is usually in addition to required Type I repairs. Since the quantity of Type V repairs that may be required is usually unknown until pavement restoration work begins, Type V repairs may be established in the Proposal on a contingent basis. C. All longitudinal and transverse asphalt replacement overlay wearing surfaces shall butt into adjacent existing asphalt wearing surfaces in full lane asphaltic pavement restoration. The finish elevation of the new full lane overlay shall meet existing elevations adjacent to the new work. D. The existing asphaltic concrete surface shall be saw cut for its full depth or 1 -inch minimum, and then stripped back for at least 2 feet into the area to be overlaid to a second cut which shall also be in clean straight lines. The second, or interior, cut edge shall be rolled with a tandem roller weighing not less than 8 tons before the overlay is applied. The stripped area shall be used to provide a smooth transition or "feather" 2-85 AveStreet City of Opa-Locka Sesame to St. & Atlantic Culvert Replacement Between NW 135 area between the overlay and the existing pavement. Before placing the overlay, all cut edges and the surface of the stripped area shall be tack coated with emulsified asphalt as specified herein below. E. If the Contractor requests in writing to "feather" the longitudinal edge, and if written permission is granted to "feather" the asphalt by the City a sanded mix of 70-30 type shall be used. "Feathering" shall begin 18 inches from the tapered edge. F. Prior to installing a full lane width overlay over existing asphaltic pavement the trench and shoulders over the pipe shall be sawcut and filled with asphaltic concrete to the required depth, terminating flush with the existing adjacent asphalt in accordance with the municipality having jurisdiction over the work for Types I, II or M. Type V overlay will be installed as detailed above. G. When a minor amount of asphalt surface will remain, generally with large pipe installations, after the pipe has been installed and the required longitudinal saw cutting of the asphaltic pavement completed, the Contractor may request permission to remove all the asphalt in the lane, by saw cutting the asphalt adjacent to the existing lane, then placing the Type V overlay flush with the adjacent asphalt. This would require that the Type I, II or M finish elevation be lowered 1 inch to allow for the Type V overlay. H. Before the overlay is applied, existing surfaces shall be swept clean of all dirt and debris, using a power driven broom if warranted by the size of the location to be overlaid and/or as ordered by the City. Pavement edges shall be cleared of all encroaching vegetation, loose sand, rock and all other foreign matter. When the existing surface is thoroughly clean, a tack coat of Emulsified Asphalt Grade RS -2 (anionic) shall be applied at the rate of approximately 0.10 gallon per square yard, immediately followed by the asphaltic concrete overlay. I. Machine -laid overlay shall be placed by means of an approved mechanical spreader and finisher, and the mixture shall be compacted to true grade and cross section by means of a tandem roller weighing not less than 8 tons. J. The compacted overlay shall be thicker as required to produce a smooth uniform surface free of any irregularities but shall not be less than one inch in thickness. Existing depressed areas in the asphaltic pavement, which could collect water after a rainfall shall be corrected before placing the asphaltic overlay. Rolling shall proceed as close behind the spreading of the asphaltic overlay as possible, and all materials shall be completely compacted the same day it is placed. 3.0.6. SLURRY SEAL COAT A.

Do not make more than two mix adjustments. Seek approval from the Engineer prior to using a central mixer and depositing the batch into a truck mixer. F. Transit Time Using Agitator Trucks: The maximum allowable transit time between the initial introduction of water into the mix and completely discharging all the concrete from the truck will be 60 minutes. The maximum transit time can be 90 minutes if water reducing and retarding admixture (Type D, Type G, or Type II) is used. Reject concrete exceeding the maximum transit time. 3-12 City of Opa-Locks Sesame Street Culvert Replacement Between NW 135th St. & Atlantic Ave G. All the concrete in a load must be in its final placement position a maximum of 15 minutes after the transit time has expired unless a time extension is approved by the Engineer. H. Adding Water to Concrete at the Placement Site: Water may be added at the placement site provided the addition of water does not exceed the water to cementitious materials ratio as defined by the mix design. After adding water, perform a slump test to confirm the concrete is within the slump tolerance range stated in Section 2.01. If the slump is outside the tolerance range, reject the load. If an adjustment is made at the concrete production facility, perform a slump test on the next load to ensure the concrete is within the slump tolerance range. Do not place concrete represented by slump test results outside of the tolerance range. Include water missing from the water storage tanks upon arrival at the project site in the jobsite water added 3.0.3. PLACING CONCRETE B. Weather Restrictions 1. Concreting in Cold Weather: Do not place concrete when the air temperature at placement is below 40°F. The requirements of concreting in cold weather do not apply to precast concrete mixing and placement operations occurring in a temperature -controlled environment. 2. Concreting in Hot Weather: Hot weather concreting is defined as the production, placing, and curing of concrete when the concrete temperature at placing exceeds 85°F but is less than 100°F . Unless the specified hot weather concreting measures are in effect, reject concrete exceeding 85°F at the time of placement. Concrete temperature shall be measured perASTM C1064. Regardless of special measures taken, reject concrete exceeding 100°F. Predict the concrete temperatures at placement time and implement hot weather measures to avoid production shutdown. B. Inspections Before Placing Concrete: Do not place concrete until the depth and character of the foundation and the adequacy of the forms and falsework have been approved by the Engineer. Do not deposit any concrete until all reinforcement is in place and has been inspected and approved by the Engineer. C. Exposure to Water: Do not expose concrete other than seal concrete in cofferdams to the action of water before final setting. Do not expose such concrete to the action of salt or brackish water for a period of seven days after placing the concrete. Protect the concrete during this period by keeping salt or brackish water pumped out of cofferdams. 3-13 City of Opa-Locka Sesame Street Culvert Replacement Between NW 1351h St. & Atlantic Ave D. Deposit concrete as nearly as possible in its final position. Do not deposit large quantities at one point and then run or work it along the forms. Take special care to fill each part of the forms, to work coarse aggregate back from the face, and to force concrete under and around reinforcing bars without displacing them. E. Use a method and manner of placing concrete that avoids the possibility of segregation or separation of aggregates. If the Engineer determines that the quality of concrete as it reaches its final position is unsatisfactory, remove it and discontinue or adjust the method of placing until the Engineer determines that the quality of the concrete as placed is satisfactory. F. Use metal or metal -lined open troughs, chutes, or other means of concrete conveyance which have no aluminum parts in contact with the concrete. As an exception, chutes made of aluminum for ready mixed concrete trucks, no longer than 20 feet, may be used. This exception does not apply to any other means of concrete conveyance. Where steep slopes are required, use chutes that are equipped with baffles or are in short lengths that reverse the direction of movement. Where placing operations would involve dropping the concrete freely more than 5 feet, deposit it through pipes, troughs, or chutes of sheet metal or other approved material. Use troughs, chutes, or pipes with a combined length of more than 30 feet only with the City"s authorization. Keep all troughs, chutes, and pipes clean and free from coatings of hardened concrete by thoroughly flushing them with water after each run or more often if necessary. G. Place concrete against supporting material that is moist at the time of concrete placement. If additional water is required, uniformly apply it ahead of the concrete placement as directed by the Engineer. The Contractor may use a moisture barrier in lieu of controlling the foundation grade moisture when approved by the Engineer. H. Place concrete in continuous horizontal layers, approximately 20 inches thick. To avoid obtaining a plane of separation or a cold joint between layers, vibrate the concrete. I. Vibrate concrete to avoid honeycomb and voids, especially at construction joints, expansion joints, valleys, and ends of form sheets. Use approved pouring sequences. J. Do not use calcium chloride or any other admixture containing chloride salts in the concrete. K. The concrete shall be placed on stabilizing or compacted subgrade to such depth that, when it is consolidated and finished, the slab thickness required by the Drawings will be obtained at all points and surface will at no point be below the grade specified for the finished surface, after application of the allowable tolerance. The concrete shall be deposited on the stabilized subgrade in a manner which will require as little re -handling as possible. Placing of the concrete shall be continuous between transverse joints, without the use of intermediate bulkheads. 3-14 City of Opa-Locka Sesame Street Culvert Replacement Between NW 135th St. &Atlantic Ave L. Concrete shall be thoroughly consolidated against and along the faces of all forms, and along the full length and on both sides of all joint assemblies, by means of hand operated, vibrators. Vibrators shall not be permitted to come in contact with joint assembly, the subgrade, or a side form. Vibration at any one location shall not continue so long as to produce puddling or the accumulation of excessive grout on the surface. In no case shall the vibrator be operated longer than 15 seconds in any one location. M. Coloring of concrete shall be done by dry -mixing the compound and broadcasting over the fresh -poured concrete after it has been struck off. N. Placing of concrete shall be so regulated that the pressure caused by the wet concrete shall not exceed that used in the design of the forms. 0. All concrete for walls shall be placed through openings in the form spaced at frequent intervals or through tremies (heavy duct canvas, rubber, etc.), equipped with suitable hopper heads. Tremies shall be of variable lengths so the free fall shall not exceed five (5) feet and a sufficient number shall be placed in the form to ensure the concrete is kept level at all times. P. When forms are removed, surfaces shall be even and dense, free from aggregate pockets or honeycomb. To achieve this, concrete shall be consolidated using mechanical vibration, supplemented by forking and spading by hand in the corners and angle of forms and along form surfaces while the concrete is plastic under the vibratory action. Consolidation shall conform to ACI 309. Q. Care shall be taken to prevent cold joints when placing concrete in any portion of the work. The concrete placing rate shall be such as to ensure that each layer is placed while the previous layer is soft or plastic, so that the two layers can be made monolithic by penetration of the vibrators. Maximum thickness of concrete layers shall be 18 inches. The surface of the concrete shall be level whenever a run of concrete is stopped. R. Placement in Wall Forms: Concrete shall not be dropped through reinforcement steel or into any deep form, whether reinforcement is present or not, causing separation of the coarse aggregate from the mortar on account of repeatedly hitting rods or the sides of the form as it falls, nor shall concrete be placed in any form in such a manner as to leave accumulation of mortar on the form surfaces above the placed concrete. In such cases, some means such as the use of hoppers and, if necessary, vertical ducts of canvas, rubber, or metal shall be used for placing concrete in the forms in a manner that it may reach the place of final deposit without separation. In no case shall the free fall of concrete exceed 4 feet below the ends of ducts, chutes, or buggies. Concrete shall be uniformly distributed during the process of depositing, and in no case after depositing shall any portion be displaced in the forms more than 6 feet in horizontal direction. Concrete in forms shall be deposited in uniform horizontal layers not deeper 3-15 City of Opa-Locka Sesame Street Culvert Replacement Between NW 135th St. & Atlantic Ave than 2 feet; and care shall be taken to avoid inclined layers or inclined construction joints where such are required for sloping members. Each layer shall be placed while the previous layer is still soft. The rate of placing concrete in forms shall not exceed 5 feet of vertical rise per hour. 3.0.4. FORMWORK A. Forms to confine the concrete and shape it to the required lines shall be used wherever necessary. The Contractor shall assume full responsibility for the adequate design of all forms, and any forms which are unsafe or inadequate in any respect shall promptly be removed and replaced at the Contractor 's expense. All design, construction, maintenance, preparation, and removal of forms shall be in accordance with the FBC, ACI 347 and the requirements specified herein. B. All forms shall be true in every respect to the required shape and size, shall conform to the established alignment and grade, and shall be of sufficient strength and rigidity to maintain their position and shape under the loads and operations incident to placing and vibrating the concrete. C. Vertical Surfaces: All vertical surfaces of concrete members shall be formed, except where placement of the concrete against the ground is called for by the Engineer. D. Construction Joints: Concrete construction joints will not be permitted at locations other than those shown or specified, except as may be acceptable to the Engineer. When a second lift is placed on hardened concrete, special precautions shall be taken in the way of the number, location, and tightening of ties at the top of the old lift and bottom of the new to prevent any unsatisfactory effect whatsoever on the concrete. E. Form Ties: Wire ties for holding forms will not be permitted. No form -tying device or part thereof, other than metal, shall be left embedded in the concrete. Ties shall not be removed in such manner as to leave a hole extending through the interior of the concrete members. The use of snap -ties which cause spilling of the concrete upon form stripping or tie removal will not be permitted. If steel panel forms are used, rubber grommets shall be provided where the ties pass through the form in order to prevent loss of cement paste. Where metal rods extending through the concrete are used to support or to strengthen forms, the rods shall remain embedded and shall terminate not less than 1 inch back from the formed face or faces of the concrete. F. Careful procedures for the removal of forms shall be strictly followed, and this work shall be done with care so as to avoid injury to the concrete. No heavy loading on green concrete will be permitted.

General: No concrete shall be placed until the reinforcement steel and formwork have been erected in a manner acceptable to the City or their designee. The Contractor shall notify the City or their designee not less than two working days prior to concrete placement, allowing for inspection and any corrective measures which are required. Earth surfaces shall be thoroughly wetted by sprinkling, prior to the placing of any concrete, and these surfaces shall be kept moist by frequent sprinkling up to the time of placing concrete thereon. The surface shall be free from standing water, mud, and debris at the time of placing concrete. B. Joints in Concrete: Concrete surfaces upon or against which concrete is to be placed, where the placement of the old concrete has been stopped or interrupted so that, as determined by the City or their designee, the new concrete cannot be incorporated integrally with that previously placed, are defined as construction joints. The surfaces of horizontal joints shall be given a compacted, roughened surface for good bond. Except where the Drawings call for joint surfaces to be coated, the joint surfaces shall be cleaned of all laitance, loose or defective concrete, and foreign material. Such cleaning shall be accomplished by sandblasting, followed by thorough washing. All 3-18 City of Opa-Locka Sesame Street Culvert Replacement Between NW 135th St. & Atlantic Ave pools of water shall be removed from the surface of construction joints before the new concrete is placed. C. Existing concrete surfaces upon or against which concrete is to be placed shall be given a roughened surface for good bond. Joint surfaces shall be cleaned of all laitance, loose or defective concrete, and foreign material. Such cleaning shall be accomplished by Thydroblasting. All pools of water shall be removed from the surface of construction joints before the new concrete is placed. D. Placing Interruptions: When placing of concrete is to be interrupted long enough for the concrete to take a set, the working face shall be given a shape by the use of forms or other means that will secure proper union with subsequent work, provided that construction joints shall be made only where acceptable to the City or their designee. E. Embedded Items: No concrete shall be placed until all formwork, installation of parts to - be embedded, reinforcement steel, and preparation of surfaces involved in the placing have been completed and accepted by the City or their designee at least 4 hours before placement of concrete. All surfaces of forms and embedded items that have become encrusted with dried grout from concrete previously placed shall be cleaned of all such grout before the surrounding or adjacent concrete is placed. F. All reinforcement, anchor bolts, sleeves, inserts, and similar items shall be set and secured in the forms where shown on the Drawings or by shop drawings and shall be acceptable to the City or their designee before any concrete is placed. Accuracy of placement is the responsibility of the City or their designee. G. Casting Against Old Concrete: Where concrete is to be cast against old concrete (any concrete which is greater than 60 days of age), the surface of the old concrete shall be thoroughly cleaned and roughened by hydro -blasting (exposing aggregate) prior to the application of an epoxy bonding agent. Application shall be according to the bonding agent manufacturer's instructions and recommendations. H. No concrete shall be placed in any structure until all water entering the space to be filled with concrete has been properly cut off or has been diverted by pipes, or other means, and carried out of the forms, clear of the work. No concrete shall be deposited under water nor shall the Contractor allow still water to rise on any concrete until the concrete has attained its initial set. Water shall not be permitted to flow over the surface of any concrete in such manner and at such velocity as will injure the surface finish of the concrete. I. Openings for pipes, inserts for pipe hangers and brackets, and the setting of anchors shall, where practicable, be provided for during the placing of concrete. J. Corrosion Protection: Pipe, conduit, dowels, and other ferrous items required to be embedded in concrete construction shall be so positioned and supported prior to 3-19 City of Opa-Locka Sesame Street Culvert Replacement Between NW 135th St. & Atlantic Ave placement of concrete that there will be a minimum of 2 inches clearance between said items, and any part of the concrete reinforcement will not be permitted. K. Cleaning: The surfaces of all metalwork to be in contact with concrete shall be thoroughly cleaned of all dirt, grease, loose scale and rust, grout, mortar, and other foreign substances immediately before the concrete is placed. 3.0.7. TAMPING AND VIBRATING A. As concrete is placed in the forms or in excavations, it shall be thoroughly settled and compacted, throughout the entire depth of the layer which is being consolidated, into a dense homogeneous mass, filling all comers and angles, thoroughly embedding the reinforcement, eliminating rock pockets, and bringing only a slight excess of water to the exposed surface of concrete during placement. Vibrators shall be high speed power vibrators (8,000 or 10,000 rpm) of an immersion type in sufficient number and with (at least one) standby units as required. B. Concrete in walls shall be internally vibrated and at the same time rammed, stirred, or worked with suitable appliances, tamping bars, shovels, or forked tools until it completely fills the forms or excavations and closes snugly against all surfaces. Subsequent layers of concrete shall not be placed until the layers previously placed have been worked thoroughly as specified. Vibrators shall be provided in sufficient numbers, with standby units as required, to accomplish the results herein specified with 15 minutes after concrete of the prescribed consistency is placed in the forms. The vibrating head shall be kept from contact with the surfaces of the forms. Care shall be taken not to vibrate concrete excessively or to work it in any manner that causes segregation of its constituents. 3.0.8. FINISHING CONCRETE SURFACE A. General: Surfaces shall be free from fins, bulges, ridges, offsets, honeycombing, or roughness of any kind, and shall present a finished, smooth, continuous hard surface. Allowable deviations from plumb or level and from the alignment, profiles, and dimensions shown on the Drawings are defined as tolerances and are specified herein. These tolerances are to be distinguished from irregularities in finish as described herein. Aluminum finishing tools shall not be used. B. Formed Surfaces: After removal of forms, the finishes described below shall be applied in accordance with Article 3.13, D. Unless the finish schedule specifies otherwise, all surfaces shall receive at least a Type I finish. The Engineer shall be the sole judge of acceptability of all concrete finish work. 1. Type I - Rough: All fins, burrs and other projections left by the forms shall be removed. All holes left by removal of ends of ties, and all other holes, depressions, or voids shall be filled solid with cement grout after first being thoroughly wetted. 3-20 City of Opa-Locka Sesame Street Culvert Replacement Between NW 135th St. & Atlantic Ave Honeycombs shall be chipped back to solid concrete as directed, prior to patching with cement grout. Holes shall be filled with a small tool that will permit packing the hole solidly with cement grout. Cement grout shall consist of one part cement to three parts sand, and the amount of mixing water shall be as little as consistent with the requirements of handling and placing. Color of cement grout shall match the adjacent wall surface. At locations where concrete coatings are specified to be applied, epoxy -based patch material or filler surfaces compatible with the coating shall be used in lieu of cement grout specified herein. Concrete finish shall be in strict conformance to the coating / paint manufacturer's recommendations. 2. Type II - Grout Cleaned: Where this finish is required, it shall be applied after completion of Type I finish. After the concrete has been predampened, slurry consisting of one part cement (including an appropriate quantity of white cement in order to produce a color matching the surrounding concrete) and 1-1/2 parts sand passing the No. 16 sieve, by damp loose volume, shall be spread over the surface with clean burlap pads or sponge rubber floats. Any surplus shall be removed by scraping and then rubbing with clean burlap. The finish shall be kept damp for at least 36 hours after application. 3. Type III - Smooth Rubbed: Where this finish is required, it shall be applied after the completion of the Type I finish. No rubbing shall be done before the concrete is thoroughly hardened and the mortar used for patching is firmly set. A smooth, uniform surface shall be obtained by wetting the surface and rubbing it with a carborundum stone to eliminate irregularities. Unless the nature of the irregularities requires it, the general surface of the concrete shall not be cut into. Corners and edges shall be slightly rounded by the use of the carborundum stone. Brush finishing or painting with grout or neat cement will not be permitted. C. Unformed Surfaces: The finishes described below shall be applied to unformed surfaces such as floors, slabs, flow channels and top of walls in accordance with Article 3.05 - Concrete Finish Schedule. The Engineer shall be the sole judge of acceptability of all such finish work. 1. Type "A" - Screeded: This finish shall be obtained by placing screeds at frequent intervals and striking off to the surface elevation required. When a Type "F" finish is subsequently to be applied, the surface of the screeded concrete shall be roughened with a concrete rake to 1/2' minimum deep grooves prior to final set. 2. Type "B" - Wood Floated: This finish shall be obtained after completion of a Type "A" finish by working a previously screeded surface with a wood float until the desired texture is reached. Floating shall begin when the water sheen has disappeared and when the concrete has sufficiently hardened so that a person's foot leaves only a slight imprint. If wet spots occur, water shall be removed with a squeegee. Care shall be taken to prevent the formation of laitance and excess water on the finished surface. The finished surface shall be true, even, and free from blemishes and other irregularities. 3-21 City of Opa-Locka Sesame Street Culvert Replacement Between NW 135th St. & Atlantic Ave 3. Type "C" - Cork Floated: This finish shall be similar to Type "B" but slightly smoother than that obtained with a wood float. It shall be obtained by power or band floating with cork floats. 4. Type "D" - Steel Troweled: This finish shall be obtained after completion of a Type "B" finish. When the concrete has hardened sufficiently to prevent excess fine material from working to the surface, the surface shall be compacted and smoothed with not less than two thorough and complete steel troweling operations. In areas, which are to receive a floor covering such as tile, resilient flooring, or carpeting, only one troweling operation is required. The finish shall be brought to a smooth, dense surface, free from defects and blemishes. 5. Type "E" - Broom or Belt: This finish shall provide the surface with a transverse scored texture by drawing a broom or burlap belt across the surface immediately after completion of a Type "B" finish. 6. Type "F" - Swept in Grout Topping: This finish shall be applied after a completion of a Type "A" finish. The concrete surface shall be properly cleaned, washed, and coated with a mixture of water and Portland Cement. Cement grout in accordance with Section 03315 shall then be plowed and swept into neat conformance with the blades or arms of the apparatus by turning or rotating the previously positioned mechanical equipment. Special attention shall be paid to true grades, shapes and tolerances as specified by the manufacturer of the equipment. Before beginning this finish, the Contractor shall notify the Engineer and the equipment manufacturer of the details of the operation and obtain approval and recommendations of the equipment manufacturer. 7. Type "G" - Hardened Finish: Either a liquid hardened finish or an aggregate hardened finish shall be provided at the Contractor's option. 8. Type "H" - Non -Slip Finish: This finish shall be provided by applying a non -slip shake -on aggregate concurrently with the application of a Type "D" finish. Application procedure shall be in accordance with manufacturer's instructions. 9. Type "J" - Raked Finish: This finish shall be provided by raking the surface as soon as the condition of the concrete permits by making depressions of +/-1/4-inch. 3.0.9.

I am writing to formally submit a revised price proposal for the Sesame Street Culvert Replacement between NW 135th St. & Atlantic Ave (RFP NO: 23- 1016200) bid, which was previously tendered to your office on September 17,2023. I appreciate the opportunity to participate in this bid, and after careful consideration and further evaluation, I believe that the revised proposal will better align with the needs and expectations of our esteemed city. Upon a thorough review of the project requirements, as well as discussions with city officials (Microsoft Teams meeting -Tuesday, October 31, 2023, 9:30 AM -10:00 AM) and with my team, and careful analysis of our cost estimates, I have identified several areas where we can offer a more competitive and cost- effective proposal without compromising the quality or integrity of our work. Our commitment to delivering value to the city remains unwavering, and we believe that the revisions we have made will better reflect our dedication to your community. To facilitate a clear understanding of the changes we have made, we have prepared a detailed item -by - item comparison between the original and revised price proposals.

ILO SAFA CONSTRUCTION, LLC Phone: (954) 326-8295 Email: md.rahman@safaconstruction.net Note for revisions in our proposal: 1) In the original bid, there was no separate line item for Bonding cost, so bonding cost was included in line item number 16, and in the revised price proposal bonding cost is shown separately in item number 26-A for clarification. 2) During the re -site visit to the construction site, we identified that unsuitable material in the canal would not be that much. 3) We feel that we do not police guard during construction. I have been working with the city past 10 years, I never felt that I needed a police guard to work in the city. So, the cost is deleted. 4) This is the city's project within its own city limit. So, the city can handle this issue internally as it was done for other projects. 5) Unforeseen conditions are unpredictable and non -measurable. The city can keep the cost for this line item internally as it was for other standard projects, In this comparison table, we have outlined the specific items, their descriptions, the original pricing, the revised pricing, and the cost savings achieved in the revised proposal. We believe this breakdown provides transparency and demonstrates our commitment to offering the best value for the city. We are confident that the revised proposal reflects our dedication to delivering a competitive and cost- effective solution for the city. Our team remains fully committed to collaborating closely with your office to ensure the successful execution of this project, should our proposal be accepted. If you have any questions or require further clarification regarding the itemized comparison or any other aspects of the proposal, please feel free to contact me directly at (954) 326-8295 or via email at md.rahman@safaconstruction.net . We are eager to engage in discussions and provide any additional information or documentation as needed. We would like to express our sincere gratitude for your consideration of our proposal and for your dedication to selecting the best value for the city. We are enthusiastic about the opportunity to contribute to the continued growth and development of our community and look forward to the possibility of working closely with your office to realize this vision. Thank you for your time and attention, and I eagerly await your response. MD Shahinur Rahman, CGC, PMP, MS, PE (CA, FL) PRESIDENT /CEO SAFA CONSTRUCTION, LLC SBE 1 CBE
