Stagging shall have to be designed with stresses of M-250 for ESR. However all RCC construction should be done in M-300 9. These rates are including the cost of uplift pressure if any and entire dewatering during execution. In case of water logging area where water is struck at shallow depth extra provision of dewatering shall be made as per site condition. 10. All condition given in the Member Secretary"s Circular No.MJP/TS-I/350/1668 dt. 2.8.97 and MJP/S-I/350/2127 dt.13.7.99 shall be strictly followed and additional cost, if any due to these conditions is included in the rates mentioned below. 11.. 75% part rate shall be payable for reinforced cocnrete and plastering items of containers of E.S.R. till satisfactory hydraulic testing for water tightness is given ; and till that work shall be treated as incomplete. 12. The rates indicated in the table are excluding the cost of pipes, specials and valves required for inlet, outlet washout overflow and by-pass arrangement. The scope of work, however inclueds cost of erecting, laying and jointing of pipes and valvews including cost of jointing materials upto 5M beyond outer face of outermost column. 13.

And minimum 10mm thickness above 500mm dia can be used with proper anti-corrosive epoxy teratment from inside and outside. 14. Below mentioned rates are for foundation, with individuals footing with bearing capacity of 30 tonnes per square metre. For raft foundations, these rates shall be increased by 7.5% wheresafebearing capacity ( SBC) is 5 M.T. per Sq.m and by 5% where SBC is more than 5 MT/Sqm. and upto 10MT/Sq.m. This percentage of 5% or 7,5% is applicable for estimation of amount of L.S. items ESR for Extra item due to change from individual footing foundation to raft actual increase in concrete and steel quantities be paid as per relevent DSR Item. 15.The rates shall be increase by 30% for brearing piles upto depth of 10m and for further increased in depth by 5M each it shall be increased by another 10% These rates are applicable where raft is not reasible for pile foundation sulfate resistant cement shall only be used. Single pile for the column is not permitted Group of piles shall be designed with pile cap for each column of ESR. 16. These rates are applicable for staging height of 12 M These rates shall be increased or decreased for per metre variation in the staging height as below 12 to 16 M staging 2% per metre 16 to 20m staging 3% per meter 20 M and abovd - 4% per metre I.e. for 17m stagging height percentage calculation will be like below 12 to16m = 4 x 2 = 8% 16 to 17 m x 1 x 3 = 3% Total = 11 % For 21 m stagging height Percentage calculation will be like below 12 to 16m = 4 x 2 = 8% 16 to 20m = 4 x 3 = 12% 20 to 21m = 1 x 4 = 4% Total = 24% 17.
