| 15 | Steel reinforcement for R.C.C. work including straightening, cutting, bending, placing in position and binding all complete above plinth level. |
| 16 | Thermo-Mechanically Treated bars of grade Fe-500D or more. |
| 17 | STONE WORK |
| 18 | Random rubble masonry with hard stone in superstructure above plinth level and upto floor five level, including leveling up with cement concrete 1:6:12 (1 cement : 6 coarse sand : 12 graded stone aggregate 20 mm nominal size) at window sills, ceiling level and the like. |
| 19 | Cement mortar 1:6(1 cement :6 coarse sand) |
| 20 | Dry rubble masonry in foundation and plinth including levelling up with cement concrete 1:6:12 (1 cement : 6 coarse sand : 12 graded stone aggregate 20 mm nominal size) upto plinth level using : |
| 21 | Blasted hard stone |
| 22 | STEEL WORK |
| 23 | Structural steel work in single section, fixed with or without connecting plate, including cutting, hoisting, fixing in position and applying a priming coat of approved steel primer all complete. |
| 24 | WATER PROOFING |
| 25 | Providing and applying integral crystalline slurry of hydrophilic in nature for waterproofing treatment to the RCC structures like retaining walls of the basement, water tanks, roof slabs, podiums, reservior, sewage & water treatment plant, tunnels / subway and bridge deck etc., prepared by mixing in the ratio of 5 : 2 (5 parts integral crystalline slurry : 2 parts water) for vertical surfaces and 3 : 1 (3 parts integral crystalline slurry : 1 part water) for horizontal surfaces and applying the same from negative (internal) side with the help of synthetic fiber brush. The material shall meet the requirements as specified in ACI-212-3R-2010 i.e by reducing permeability of concrete by more than 90% compared with control concrete as per DIN 1048 and resistant to 16 bar hydrostatic pressure on negative side. The crystalline slurry shall be capable of self-healing of cracks up to a width of 0.50 mm. The work shall be carried out all complete as per specification and the direction of the engineer-in-charge. The product performance shall carry guarantee for 10 years against any leakage. |
| 26 | For horizontal surface one coat @1.10 kg per sqm. |
| 27 | Providing and laying water proofing treatment over the concrete surface by applying cement based two component polymer modified water proofing slurry coating (SIKA Topseal 109 or equivalent) after cleaning the surface free from scale, rust, grease, oil etc. preparing the surface to be true and flat and saturated mixing the liquid (A) and powder (B) components in the required ratio, applying in required number of coats with a suitable interval for hardening in between and finally finished by rubbing down with a soft, dry sponge including protecting the applied surface from direct sunlight and strong wind and curing by gunny bags or polythene sheeting upto 5 days etc. complete as per manufacturer recommendations.
