Design, Manufacture, Supply & Installation of factory-made (wet cast) Precast U Shape storm water drain (SWD) heavy/medium duty type of size 450 X 450mm (Internal dimensions) with 4nos. weep holes in each precast segment of 2.0m length. Precast U Shaped segments shall consist of high strength reinforced cement concrete duly steam cured in a controlled environment and manufactured by using high performance self-compacting concrete of M-50 grade using cement of Gr. 53 as per IS: 12269 and TMT steel reinforcement bar of Grade Fe-500D as per IS: 1786 (minimum reinforcement content shall be 8.0 Kg per running metre length). The precast drain shall 1 be designed considering maximum of all possible loads (All types of Load coming while placed between the tracks considering traffic block/traffic movement on track, considering saturated/Unsaturated soil condition, all type of static & Dynamic load considering minimum track centre of 4.265m) . Length of each precast drain segment shall not be less than 2.0m. Concrete shall be cast in leakproof steel moulds maintaining precise product dimensions. Design shall confirm to IS/BIS / Indian Railway Concrete bridge code / JIS standards/Guidelines/Codes. Precast drain shall take into account expected handling and erection stresses etc. The product shall have tie/groove shape joint 10-20 mm width X 25 mm depth groove on both sides for jointing two precast drain segments. The precast segment shall consist of special in-built inserts at appropriate location for safer and faster installation. Joint shall be filled up with factory made non-shrink grout material of approved make. Precast Factory shall have in-house NABL approved testing facility for quality checks and shall have ISO 9001, ISO 14001 and ISO 45001 certification for design, manufacture and dispatch of products and shall be ZED certified. The precast manufacturer should have proven track record in production & supply of precast products. The rate is applicable for supply of precast product at various stations of MB Division and is inclusive of all loading, leading, unloading, handling, rehandling, all applicable taxes, installation and jointing, curing etc. complete item. The rate is exclusive of Earthwork in excavation, dewatering, PCC (1:3:6), benching concrete (M-30) inside drain to provide required longitudinal slope & leading surplus earth outside Railway boundary, which shall be paid under relevant DSR Items."(under traffic block)"
