Trench walls shall be vertical in streets or improved areas unless otherwise • authorized by the Engineer. Provide bracing, sheeting and cribbing where necessary to prevent caving. ' (b) All sheeting shall be pulled immediately prior to backfilling around the sheeting. However,the Engineer may direct all or a portion of the sheeting to be left in place in order to protect the pipe against shock load of caving ' banks, or to protect adjacent street or property, or to prevent material that cannot be compacted to specified density from caving into the trench. (c) Where sheeting is left in place, do not brace against pipe, but support in a manner which will not apply concentrated loads or horizontal thrusts on the pipe. Cross braces above the pipe may be removed after backfill to top of ' pipe has been completed. ' (d) Trench walls may be sloped in unimproved areas if required to prevent caving and if adjacent property or trees to be left in place are not thereby subjected to 1 additional cutting of roots.

(b) Granular fill shall be clean river gravel or reasonably sound crushed ' limestone,free of cementitious,shaly,or flat and flaky particles in an amount which would cause the material to cake or pack or otherwise form an unyielding support for the pipe. Gradation shall be such that at least ninety- ' five(45)percent passes a three-quarter(3/4)inch square mesh sieve and not over live(5) percent passes a number four(4)square mesh sieve. (c) Stabilization: If the trench bottom at base of the required pipe embedment ' material is unstable,the contractor shall excavate to an additional depth and backfill with crushed stone as directed by the Engineer.

Screed granular fill as shown on the Plans under elliptical or arch pipe. 1 3. For a length of two (2) pipe diameters (effective diameter equals average of span and rise for elliptical or arch pipe) on the upstream ' • ends of culverts, omit granular fill. Use selected clay screeded and compacted to not less than ninety(90)percent of Standard Density. ' TS-2.3.4 Bell Holes: Dig bell holes where pipe has bell joints.

Suitable material from the project ' excavation shall be brought in from elsewhere on the work where required. (d) Place alongside pipe in loose layers of six (6) inch maximum thickness, thoroughly compacting each layer. Take special care to place and compact • material around the pipe so as to leave no voids and to provide uniform 1 8 lateral support for the pipe. Bring materials up uniformly on both sides of • t pipe, taking special care with corrugated metal pipe. (e) The material shall be compacted to the same density as required for backfill , above top of pipe. , TS-2.3.6 Backfill Above Ton of Pine: (a) General: Backfill from top of pipe to original surface or to sub-grade where ' pavement is to be placed is covered by this section. (b) Materials: ' 1. Material for backfill above top of pipe shall be the same as for backfill below , top ofpipe as specified in subparagraph TS-2.3.5(c),except that small sticks and roots less than one-half(1/2) inch in diameter, interspersed hard lumps and clods will be allowed insofar as they do not interfere with specified ' compaction. More suitable material shall be brought from elsewhere on the project if necessary and the unsuitable material disposed of. If the specified compaction cannot be obtained with earth excavated from the trench, the , contractor shall use granular fill or similar approved material at his own expense. • 2. Rock larger than one (1) inch shall not be placed within three (3) inches of , pipe. Rock larger than eight(8)inches shall not be placed within two(2)feet ' of the top of pipe. No rock larger than two (2) inches may be placed in the upper six (6) inches under pavement sub-grade. No rock may be placed in the upper twelve (12) inches of trenches through grass parkways or earth , areas. 3. Large stones may be placed in the remainder of the backfill only if well , separated and so arranged that no interference with the specified backfill will result. (c) Methods: ' 1. Method of backfill used shall not impose excessive concentrated or ' unbalanced loads, shock, or impact on, or cause displacement of the pipe. The backfill shall be slowly rolled dawn a slope at the end of the trench and shall not be pushed over the side of the trench. , 2. Consolidated material weighing more than one hundred (100) pounds shall not be permitted to fall more than three (3) feet into the trench unless ' cushioned by at least three (3) feet of backfill over top of pipe. • 9 , 1 . (d) Compaction: 1. Backf ill under pavement shall be defined as being under all areas to be paved or surfaced for vehicular access, except those to be surfaced with crushed ' stone. The limiting line for such backfill shall extend from sub-grade at twelve(12)inches beyond edge of pavement or back of curb,downward on a slope not steeper than one(1)to one(1). In areas so defined,backfil)shall be ' not less than ninety-five(95)percent of Standard Density. 2. Backfill in Other Areas:In areas not defined in Item 1 above,backfill shall be ' not less than ninety (90)percent of Standard Density. 3.

Internal vibrators shall not be held against the forms or reinforcing steel. • The number of vibrators employed shall be sufficient to consolidate the concrete , within 15 minutes after it has been deposited in the forms. At least two vibrators in , good operating condition shall be available at the site of the structure in which more than 25 cubic yards of concrete is to be placed.

ADDENDUM: There is an addendum for the project which Includes storm drainage at the airport, drawings and details are Included with the addendum. No questions will be allowed after 12:00 PM,Thursday, June 2 at 12:00 noon. ' PLAN REVIEW: • Attention was drawn to each area of the plans. • In area#1 it was noted that the beginning of the system would Ile to an existing Intel, and that the end of ' the new system would tie Into the existing system, the location of which would need to be verified. All ' "building a better community" Memorandum 2 Subject: Pro-bid Conforance ' • existing pipes and structures not being use are to be removed. • In area #2 the beginning of the system ties to an existing pipe, the exact location Is to be verified. The stormwater pipe will be placed under the sanitary sewer and a section of sewer is to be replaced with additional manholes.The hatched area of the intersection shall be rebuilt according to the typical section, • In area #3 the Intersection is to be rebuilt as shown on the plans. Be mindful of the energy dissipater ' detail for the outlet structure of this system. • In area #4 the new system will have to tie to the old system at Hart Street. A portion of High Street will need to be built up with lifts of asphalt to reduce the cross slope, follow the cross sections. The sewer laterals and water service lines along High Street may need to be relocated, this work needs to be done by a licensed plumber. Care need to be taken at structure #27 as the pipe goes under the existing telephone conduits. • In area#5 the system will tie Into an existing pipe.The entrance to Cuba Street is to be replaced,and the curbing modified to ensure water reaches the existing inlet. • Area #6 is an alternate to the project. This alternate may be accepted in its entirely or potentially the removals and replacement of the curb only. • In area #7 the approach of Franklin Street shall be replaced with attention paid to creating proper ' drainage across the entrance of the street. The existing CMP under Lafayette is to be filled with grout. • There is an addendum to the project concerning the construction of storm drainage at the airport. Drawings for this have been included with the addendum. ' • There are a number of utilities that will be exposed during the project. A number of water lines are close to the proposed system and some slight adjustments to the design may be needed to avoid these lines. Others cannot be missed and the contractor will need to work with Missouri American Water for their relocation.
