Remaining works of Public Health College, Jodhpur (Including GST) (Excluding Cost of Cement and Electrical works)

Providing and laying in position cement concrete including curing, compaction etc. complete in specified grade excluding the cost of centering and shuttering - levelling course etc up to floor five level

M15 grade Nominal Mix 1: 2: 4 (1 cement : 2 coarse sand : 4 graded stone aggregate 20mm nominal size).

Providing and mixing integral crystalline admixture for waterproofing treatment to RCC structures like basement raft, retaining walls, reservoir, sewage & water treatment plant, tunnels/subway and bridge deck etc. at the time of transporting of concrete into the drum of the ready mix truck, using integral crystalline admixture @ 0.80% (minimum) to the weight of cement content per cubic meter of concrete or higher as recommended by the manufacturer's specification in reinforced cement concrete at site of work.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. The crystalline admixture shall be capable of self-healing of cracks up to a width of 0.50 mm. The work shall be carried out complete as per specification and the direction of the Engineer-in-charge. The product performance shall carry guarantee for 10 years against any leakage.

Providing and applying integral crystalline slurry of hydrophilic nature for waterproofing treatment to RCC structures like retaining walls of basement, water tanks, roof slabs, podiums, reservoir, sewage & water treatment plant, tunnels/subway and bridge deck etc.The material shall meet ACI-212-3R-2010 requirements 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.

For vertical surface two coats @ 0.70 kg per sqm

For horizontal surface one coat @ 1.10 kg per sqm

Providing and applying swellable type water stop tape, 19 mm × 25 mm thick in linear meter (expansive nature) for construction joints treatment of RCC structures such as raft slab, retaining walls, water storage tanks and junctions of raft slab with retaining walls etc. After cleaning the surface, one coat of required primer for swellable water stop tape shall be applied throughout the length of the joint @ 3.78 litre per 240 running meter. Over the primed surface swellable water stop tape shall be placed. The work shall be carried out complete as per specification and direction of Engineer-in-charge. Product performance shall carry guarantee for 10 years against leakage.

Providing and applying crystalline mortar by mixing in ratio 4.5:1 (4.5 parts crystalline mortar : 1 part water) for treatment of faulty construction joints, cracks, tie rod holes and honeycombed surfaces of RCC underground structures like basement, water tanks and bridge deck etc. to ensure water tightness. The crystalline mortar shall conform to EN 1504-3 having compressive strength Class R4/45 MPa and adhesive bond strength Class R3/1.5 MPa.

For sealing cracks and faulty construction joints, routed out/making U-shape groove size 25×25 mm and priming area with integral crystalline slurry @ 0.05 kg/running meter and filling groove with crystalline mortar @ 1.50 kg/running meter. After touch dry, two coats of integral crystalline slurry @ 0.05 kg/running meter per coat.

For patching of tie rod holes, prepared tie rod hole surface and primed with integral crystalline slurry @ 0.070 kg/sqm and filled with crystalline mortar @ 0.040 kg per hole.
