BOQ
| Sl. No. | Item Description |
| 1 | Disconnecting and taking down unserviceable earthing any type & size including all accessories from installations/ bldgs/ communication centers complete all as directed by Engr-in-Charge. |
| 2 | Material and Labour for Conductive Concrete Earth Grid of multiple interconnected Earth Electrodes to achieve the earth resistance value of less than < 3 Ω. The excavation is to be carried out in any type of soil including hard rock. The necessary soil treatment to be carried out to achieve the desire result. The approx specification are as under:-(i) Earth Electrodes: Metal conductor - Copper bonded MS rod dia 17.2 mm (+/-.5mm), Length 3 meter with conductive concrete with bore dia 85mm to 100 mm, Length 3 meter of earth electrode. (ii) All earth electrodes should be installed in specially treated soil earth pits of size 1.5 meter x 1.5 meter x 3 meters each (Minimum four Earth Pits) shall be prepared by removing high resistivity soil/ rock. The earth pits to be filled with fresh low resistivity sieved soil and compacted with water. The soil treatment chemical should be non corrosive, highly conductive & there shall not be need of water for electrical conductivity. (iii) Interconnected Strip: All the multiple Earth Electrodes will be horizontally interconnected with metal conductor - Copper strip flat size : 25mm x 3 mm & conductive concrete embedding size : 75 mm².(iv) Test Link : Test links - Copper strip flat size : 50 mm x 6 mm x 200 mm shall be provided, at any one of the four Earth Electrodes of the grid for connection between earth grid pit and application.(v) Pit Cover : RCC pit cover & frame shall be provided at all Earth Electrode (with test links). (vi) Two Nos of earth strip of size 25x3mm shall be laid from earthing to test point and duly embedded in conductive concrete of size 75 mm2.(vii) Each earth pit base to be provided with strip mesh of size 1200mmx1200mm usinbg copper earth strip of size 25x3mm. Mesh shall be made with 7 Nos of GI strip in length and width and embedded in condutive concrete of 100mm thick. |
| 3 | Note :- (a) Bidder shall produce certificate for resistivity of conductive concrete.(b) Fault Current Tested at 35 KA Peak With 17.2mm copper bonded rod of 3mtr length embedded With Conductive Concrete.(c ) On completion of work, Engineer-in-charge will check the earth resistance in presence of user, Contractor will re-do the earth if earth resistance value is found more than 3 Ohm.(d) All connecting strips would be of copper of size 25x3 mm and cost of the same is included in the rate quoted, upto test point.(e) Test certificate of earthing material for ROHS compliance, Resistivity value and fault current test for electrode from certified NABL laboratory shall be submitted. (f) Contractor will annually check the resistance value of earth grids after completion of work if value not found as per contract the necessary action to be taken by the contractor for achieving the desire result. The contactor will maintain earthing for upto 10 year.(g) The contractor to provide CPRI test report for current greater than 20 KA with peak at 38 KA, The report shall not be more than 10 year old from the date of tender. (h) The product should be ROHS compliance. (j) The contractor to submit unconditional guarantee for 10 years for replacement of earthing, if results are not satisfactory. (k) The earthing to be carried out by OEM only. The MOU in this respect to be submitted by contractor before commencement of work to GE. |
| 4 | Supply and fixing of Earth continuity conductor or main earthing lead fixed to wall on batten or recess or chases or burried in ground or drawn in conduit/pipe or fixed to poles or any other indicated situation for loop earthing etc. as required of size 20x3mm copper strip complete all as specified and directed.
