Including all newly used MS/GI shuttring and scafolding etc. supply of all materials, labours, T&P etc all complete the work upto the satisfaction of Engineer-In-Charge. For bidding purpose, bearing capacity of soil shall be considered as 8 t/sqm. working design shall be based on the SBC determind after soil investigation /8 tonne/sqm including requird earthfilling for maintaining FGL as per level of nearest road level, cost of earth required for filling not to be paid extra. 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, layout as ground level of over head tank consider from 100 cm above than near of road surface to be finalized by the engineer in charge including, campus cleaning, removal of debries, bush cutting and disposal with in municipal limt and filling ogf earth if required as per direction of Engineer in charge. The successful bidder will be required to investigate the soil bearing capacity. If not 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.
