RCC ESR Capacity of 25000 Liters, for 12 Meter Staging Item No.1 Designing (aesthetically), and constructing RCC elevated service reservoirs of following capacity with RCC staging consisting of columns, internal and external bracings spaced vertically not more than 4.5 meters centre to centre for E.S.R. having capacity 500 m3 & not more than 6 m c/c for E.S.R.having capacity above 500 m3 including excavation in all types of strata, foundation concret, cement plaster with water proofing compound to the inside face of the container including refilling disposing of the surplus stuff within a lead of 50 meters, all labour and material charges including lowering, laying, erecting, hoisting and jointing of pipe assembly of inlet, outlet, washout, overflow and bypass arrangements as per departmental design. providing and fixing accessories such as M.S. ladder, C. I. manhole frame and covers water level indicatiors, lightening conductor, G. I. pipe railing around walk way and top slab, providing spiral staire case from ground level to roof level, M.S.Grill gate of 2 Mtrs height with locking arrangement, B.B. masonry chambers for all valves, ventilating shafts, providing and applying three coats of cement paint to the structure including roof slab and epoxy paint to internal surface & anti-termite treatment for underground parts of the structures and giving satisfactory water tightness test as per I.S. code, The job to include painting the name of the scheme and other details on the reservoir as per the directions of Engineer-in-charge. For raft Fundation Increase vate by 7.5% Notes: 1. The design of the structure be in accordance with relevent (I.S.3370 - 1965 or revised) 2 3. For design having more than 6 columns, Providing of internal bracing is obligatory,. External bracking is also obligatory. 4.. The entire structure shall be in M/300mix only. 5. Plain round mild steel bars grade - I confirming to I.S,432 Part-I or high yield strengh 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 gound level. 7. These rates include providing, M.S. ladder for E.S.R's upto 2 lakhs liters capacity and providing sprial staircase for E.S.R. above 2 lakhs liters capacity. 8. Stagging shall have to be designed with stresses of M-200 for ESR. However all RCC construction should be done in M-250 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. For ESR upto 500cum capacity C.I.D. double flanged pipes upto 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 thick ness up to 500mm dia. 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 foundations with individual footing with bearing capacity of 20 tonnes per square metre. For raft foundations, these rates shall be increased by 7.5% where safe bearing capacity (SBC) is 5 MT per sqm and by 5% where SBC is more than 5 MT/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 foundation to raft, actual increase in concrete and steel 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 increased by another 10%. These rates are applicable where raft is not feasible. For pile foundations 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.The rates are applicable for staging height of 12 M. These rates shall be increased or decreased for per metre 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 & 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& 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 zones plan before estimation and adopt appropriate rates as per actual seismic zones.
