OVER HEAD TANK

Design, Supply of all materials, labour, T&P etc required for construction of Intz type RCC Over Head Tank including various works like - soil testing, Ventilator and Water level indicator, Lightening conductor, C.I. D/F Verticle pipes (Inlet Pipe, Outlet Pipe, Overflow Pipe & Washout Pipe), duck foot bend, puddle collers and bell mouths, Sluice valve on inlet, outlet & washout pipe and Valve Chamber, Bye-pass arrangement of OHT, Flooring, Apran & Drain (100 mm thick PCC of 1:2:4 & 100 mm thick RCC of 1:1.5:3), Floor shall be 30 cm above the finished ground level of Campus, Two coat apex painting over one coat primer of approved colour after finishing of RCC surface with grinder, repair of pin holes, unevenness., Railings - G.I. Pipe railing around stair case (both sides), balcony & top dome periphery, S.S ladder from opening of top dome to bottom dome, Stair case (Seperate two column based RCC staircase and 1 m wide balcony with arrangement of M.S Gate and Jali), Food grade epoxy coating of FOSROC / Ciba-Geigy or reputated brand on inside surface area of water container after testing for water tightness, of capacity and staging mentioned as under: For bidding purpose, bearing capacity of soil shall be considered as 8t/sq.m. Working design shall be based on the SBC determind after soil investigation / 8 tonne/sqm whichever is less complete in all respect as directed by Engineer –in-charge. Note :- The bid price of Over Head 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 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 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. To accommodate for the additional cost required, in the eventuality of net safe allowable bearing capacity falling below 8 t/m2, the payment shall be made as extra item of work.
