D/F Vertical Pipes (Inlet Pipe (2 Nos.), Outlet Pipe (2 Nos.), Overflow Pipe & Washout Pipe)(separate column pipes for the inlet for each rising main and a separate outlet for each DMA), Duck Foot Bend, Puddle Collars and Bell Mouths, DI/D/F Sluice Valves on Inlet, Outlet & Washout Pipes and Sluice Valve Chambers, Bypass Arrangement of OHT, Flooring with Apron & Drain (minimum 100 mm thick PCC of 1:2:4 & 100 mm thick RCC of 1:1.5:3 with nominal reinforcement), the construction of a 30x30 cm cement concrete (CC) drain with an internal wall thickness of 100 mm, over a 60 cm wide plain cement concrete (PCC) base of 100 mm thickness in 1:2:4 mix, for rain water disposal of campus, shall be carried out for a minimum length of 100 meters along the boundary wall of the campus up to the disposal point, Floor Level shall be 60 cm above the Finished Ground Level of Campus including supply of earth to fill the whole campus according to the formation level(floor) of OHT, Three Coats of Apex Painting over One Coat Primer of Approved Colour after Finishing of RCC Surface with Grinder, Repair of Pinholes, Unevenness, supply and fixing of two number 60 Watt solar light system (with dry battery) at the height of second brace of the OHT near stair case and main gate, Railings – G.I. Pipe Railing around Staircase (both sides), Balcony & Top Dome Periphery, S.S. Ladder from Opening of Top Dome to Bottom Dome, Staircase (Separate Two-Column Based RCC Staircase including Escape Channel of 20 m Length, Box-Type Enclosure at the Entrance of the Staircase having Locking Arrangements, and 1.20 m Wide Balcony), Food Grade Epoxy Coating of FOSROC / Ciba-Geigy on Inside Surface Area of Water Container after Successful Testing for Water Tightness of Following Capacity and Staging mentioned as per BOQ. For bidding purposes, the bearing capacity of soil shall be considered as 8 t/sq.m. Working design shall be based on the SBC determined (The depth of the bore hole shall be two times of proposed diameter raft foundation of OHT) after soil investigation / 8 tonne/sq.m. The depth of foundation is a minimum 2.50 m from the existing ground level on raft foundation or pile-cum-raft foundation or at a greater depth based on the design of the tank, for which no extra claim shall be entertained. Note: The bid price of Overhead Tanks is to be submitted considering net safe allowable bearing capacity as 8 t/m², keeping the minimum foundation depth to be 2.5 m below the existing ground level at the site of work. The successful bidder will be required to investigate the soil bearing capacity. If net safe allowable bearing capacity is found to be equivalent to or more than 8 t/m², the design of OHT will be based on 8 t/m² capacity. However, in case the net safe allowable bearing capacity is found to be below 8 t/m², then the design of OHT will be based on the actual bearing capacity, adopting raft foundation or raft-cum-pile foundation.
