The design of the tank shall be based on safe bearing capacity of soil at site i.e. 8.0 T/m2 (datum) and depth of foundation as 2.50m (datum) from existing ground level on pile/raft foundation. Made up level of OHT will be taken as 0.60 m above existing gound level. Extra earth for filling of made up level will be arranged by the contractor at his own cost. The height of staging will be considered from the made up ground level to the ring beam (Top Face) of bottom dom.

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. The contractor has to accommodate for the additional cost required, in the eventuality of net safe allowable bearing capacity falling below 8 t/m2.
