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.
