Making of boundary by cutting, welding of departmentally supplied Rail Pole and work of Channel, Angle Iron along a portion of the delivery pipeline of the 1000 G.P.M. Pump in operation at the Main Sump, under Bokaro Colliery, BnK Area

Amount

Excavation of the cable trenches in hard rock not exceeding 1.5 metres in width, and lift upto 1.5 metres, including getting out the excavated soil and disposal of excavated soil as directed within a lead of 50 metres. (0.91 mtr. X 0.91 mtr. X 0.91 mtr. = 0.75 cum x 30 nos. of poles = 22.5 cum

Providing and laying in position cement concrete 1:2:4 (1 cement: 2 coarse sand : 4 graded stone aggregate 20 mm nominal size) in foundation of pump, DG set etc. including form work etc. as required. 0.91 x 0.762 m x 0.762 m = 0.528 cum x 30 nos. of poles = 15.84 cum

Cutting of 6" dia M.S./ G.I. Pipes for smooth surface making as required for flange (Cutting of one no. of 10 metre length of 90 lbs Rail Pole into 6 pieces of 5 feet each = 77.4025 x 5 = 387.01"), Thus, for making 30 no. of pieces = 387.01 x 5 = 1,935.05"

Structural steel work riveted, bolted or welded in built up sections, trusses and framed work, including cutting, hoisting, fixing in position and applying a priming coat of approved steel primer all complete. (Jointing 15 x 2 nos. of 0.5 metre length of 100 mm x 50 mm x 6 mm Channel Iron) equivalent to 15 x 2 x (9.56 kg/m x 0.5 m) = 143.4 kg plus 48 metre length of 50 mm x 50 mm x 6 mm Angle Iron (48 m x 4.5 kg/ m = 216 kg); Total = 359.4 kg
