Earthing of quarters and public building in Belpahar Integrated Township, Lakhanpur Area, MCL

Supply, installation and commissioning of maintenance free earthing system, earth resistance upto 01 ohm with test certificate . Specification: Earthing electrode-50/3 MTPCB, 3M X 58mm , THK:50, 250 Micron copper coating on GI Pipe, Terminal Size-40/6, Inner strip-25x3, Filling material-BFC silica base bentonite powder 50Kg, Earth pit digging by spiral machine, Pit Cover- Poly Plastic (BIG) Primary earthing electrode (outer pipe) of 99.9% pure copper coating(250micron) on GI Pipe( diameter 58mm)X3mtrs . The hollow space of the electrode is duly filled with a highly conductive and non-corrosive compound (graphite power) which safeguards the secondary electrode getting corrode over a long period of time under the soil. Also the compound ensures the easy distribution of leakage/fault current lands on the electrode, Both the ends of the electrode are permanently sealed and the top portion of the earth electrode is compressed to form and extended lead with 2 holes on the terminal for connecting to the load/equipment.Warranty-5 years.

Supplying and laying 6 SWG G.I. wire at 0.50 metre below ground level for conductor earth electrode, including connection/ termination with GI thimble etc. as required.

Demolishing lime concrete manually/ by mechanical means and disposal of material within 50metres lead as per direction of Engineer- in-charge-Nominal concrete 1:3:6 or richer mix (including equivalent design mix)

Providing and laying in position excluding cement concrete of level: specified grade the cost of centering and shuttering - All work up to plinth-1:2:4 (1 cement : 2 coarse sand (zone-Ill) derived from natural sources : 4 graded stone aggregate 20 mm nominal size derived from natural sources)

Supplying and drawing following sizes of FRLS PVC insulated copper conductor, single core cable in the existing surface/ recessed steel/ PVC conduit as required-1 x 1.5 sq. mm

Total impact of GST plus Labour Cess [@ 1 % (BOCW Cess to be deducted from the RA bill as per the value of the work progress)] for the purpose of CTC
