For bidding purposes, the bearing capacity of soil shall be considered as 7.0 t/sq.m. Working design shall be based on the SBC determined (The depth of bore hole shall be two times of proposed dia meter raft foundation of OHT) after soil investigation / 7.0 tonne/sq.m. The depth of foundation is minimum 3.0 m from existing ground level on raft foundation or pile-cum-raft foundation or at more depth based on the design of the tank, for which no extra claim shall be entertained. The height of columns shall be desided by considering the natural ground level and formation level of floor of OHT. The staging shall be accounted between floor level to bottom ring beam. Note: The bid price of Overhead Tanks is to be submitted considering net safe allowable bearing capacity as 7.0 t/m², keeping the minimum foundation depth to be 3 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 7.0 t/m², the design of OHT will be based on 7.0 t/m² capacity. However, in case the net safe allowable bearing capacity is found to be below 7.0 t/m², then the design of OHT will be based on the actual bearing capacity, adopting raft foundation or raft-cum-pile foundation.
