S. code. The job to include painting the name of the scheme and other details on the reservoir as per direction of Engineer-in-charge. Notes - 1. The design of the structure be in accordance with relevant ( I.S. 3370 -1965 or revised.) 2. The design shall satisfy the stipulations as per I.S. 1893 - 1984 and I.S. 13920/1993 for seismic force and I.S. 11682/1985 for RCC staging of overhead tanks 3. For design having more than 6 columns, provision of internal bracing is obligatory. External bracing is also obligatory. 4. The entire structure shall be in M-250 mix only. However concrete in contact with water such as container, base slab, wall, roof slab & footing in water borne area shall be in M-300. 5. Plain round mild steel bars grade - I confirming to I.S. 432 part - I or high yield strength deformed bars confirming to I.S. 1786 or I.S. 1139 shall be used, grade - II mild steel bars will not be allowed. 6. Irrespective of the type of foundation proposed in the design, one set of bracing be provided at the ground level. 7. These rates include providing M. S. ladder for ESR's up to 2 lakhs liters capacity and providing spiral staircase for E.S.R. above 2 lakhs liters capacity. 8. Staging will have to be designed with stresses of M – 200 for ESR. However all construction should be done in M-250. except concrete in contact with water shall be designed & constructed 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 conditions 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 condition conditions is included in the rates mentioned below. 11. 75 % part rate shall be payable for reinforced concrete and plastering items of containers of ESR till satisfactory hydraulic testing for water tightness is given: and till that work shall be treated as in complete. 12. The rates indicated in the table are excluding the cost of pipes, specials and valves required for inlet, outlet, washout, overflow and bypass arrangemnet. The scope of work, however, includes cost of erecting, laying and jointing of pipes and valves including cost of jointing materials upto 5 M beyond outer face of outer most column. 13. For ESR up to 500cum capacity C.I.D double flanged pipes up to 300mm dia shall be provided and C.I. specials shall be used. For ESR above 500 cum capacity C.I/M.S pipes assembly with minimum 8mm thickness up to 500mm dia and minimum 10mm thickness above 500mmdia can be used with proper anti-corrosive epoxy treatment from inside and out side. 14. Below mentioned rates are for foundation with individual footing with bearing capacity of 30 tonnes per square meter. For raft foundatons, these rates shall be increased by 7.5 % where safe bearing capacity (SBC) is 5 MT per sq. m and by 5% where SBC is more than 5MT /sqm and upto 10 MT / sqm. This % of 5 % or 7.5 % is applicable for estimation of amount of lumpsum item of ESR. for extra item due to change from individual footing foundation to raft, actual increase in concrete and steel quantities be paid as per relevant DSR item. 15. The rate shall be increased by 30% for bearing piles upto depth of 10 M and for further increased in depth by 5 M each, it shall be incerased by another 10%. These rates are applicable where raft is not reasible. For pile foundation sulphate 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 of decreased for per meter variation in this staging height as below. 12 to 16 M staging - 2 % per metre 16 to 20 M staging - 3 % per metre 20 M and above - 4 % per metre For 17 M staging height, percentage calculation will be like below: 12 to 16 M --- 4 x 2 = 8% 16 to 17 M --- 1 x 3 = 3% Total = 11 % For 21 M staging height, percentage calculation will be like below: 12 to 16 M --- 4 x 2 = 8% 16 to 20 M --- 4 x 3 = 12% 20 to 21 M --- 1 x 4 = 4% Total = 24 % 17. Following rates are for seismic zone III. For zone IV, these rates shall be increased by 5% and for zone II, these rates shall be decreased by 5%. Concerned Executive Engineer shall confirm the seismic zone for the scheme from seismic zone splan before estimation and adopt appropriate rates as per actual seismic zones. (Seismic maps attached in this CSR) Notes Condition from Sr. No. 1 to 10 shall form a part and parcel of the tender papers and must be included in the draft tender paper for work of R.C.C. E.S.R Condition from Sr. No. 11 to 16 are for estimation purpose only and shall not appear in the tender. 'Cost of 6.25 Lakh Liter & 18 M staging With piping & valve Arrangements 1
