The manholes shall not have steps. The manhole walls may be pre-cast manhole sections. All voids in the cement surface will be repaired. Lifting holes shall be repaired with hydraulic cement prior to manhole testing. If, after the manhole has been backfilled, the walls or invert show evidence of groundwater entering the manhole, the leak shall be repaired. Repairs shall be made by gouging out the defect in the concrete and repairing it with nonshrink grout, hydraulic cement, or other acceptable waterproofing agents. The completed manhole shall still pass vacuum testing as described elsewhere herein. Where manhole depth is measured for payment, the payment shall be measured from the top of the cast iron cover to the outlet flowline of the manhole. Where manholes aze a unit price item, the itern shall include the inflow insert and chimney seal as specified herein. The CONTRACTOR shall be responsible for any additional cost incurred if field conditions necessitate a change in manhole depth after the pre-cast units are ordered. Grout all interior joints with hydraulic cement. All new/replacement manholes shall be vacuum tested as described elsewhere herein. All new/replacement manholes located in or directly next to pavement shall have a concrete pad constructed around the ring. The use of brick for manhole construction is not allowed in this project. Similazly, the use of bricks to adjust manhole rings to grade is not acceptable. Where the adjustment of manhole ring elevation is required, the CONTRACTOR shall utilize the precast concrete adjustment rings for this purpose. All interior concrete surfaces of all new manholes shall be coated with a corrosion resistant coating as specified elsewhere herein. A water stop such as Ram-Neck sha11 be used between manhole and grade rings, as necessary. All interior surfaces of all manholes constructed in this project shall be coated with 2-part corrosion resistant coating. The coating shall consist of a primer coat of Tnemec Series 66, Hi- Build Epoxoline followed by a finish coat of the same material. Coatings shall be installed in strict conformance with the coating manufacturers recommendation, including a minimum 28- day curing period for all concrete surfaces prior to coating. Color sha11 be tan or light gray. Coating shall be applied before installation, by the CONTRACTOR, once the precast manhole sections have been delivered to the job site, or factory applied. Fiberglass Manhole Fiberglass reinforced manholes scheduled as replacements shall be manufactured from commercial grade polyester resin or other suitable polyester or vyinyl ester resins with fiberglass reinforcements. Manhole shall be a one piece unit manufactured to meet or exceed all 91
