For design having more than 6 columns, provision of internal bracing is obligatory. External bracing is also obligatory. 5. The entire structure shall be in M-30 mix only. 6. Round mild steel bars grade - 1 Conforming to I.S. 432 part-I or high yield strength deformed bars Conforming to I.S. 1786 shall be used, grade-II mild steel bars will not be allowed. 7. Irrespective of the type of foundation proposed in the design, one set of bracing be provided at the ground level. 8. These rates includes providing M.S. ladder for E.S.R.'s upto 2 lakh litres capacity and providing spiral staircase for E.S.R. above 2 lakh litres capacity. 9.
