(xi) No further maintenance or periodic watering or recharge shall be required in earthing during its guarantee period of over 03 years in all type of soil including soft/ disintegrated or hard rock.

(xii) During the guarantee period, if earth resistance is not maintained less than 1 ohm the contractor has to redo or rectify at no extra cost to Govt till desired result is maintained. (xiii) A security deposit of value equal to 2.5 % of the rate quoted for chemical earthing for each earthing shall be retained from payment due to the contractor from final bill for the guarantee period. (xiv) The electrode shall carry manufacturer's name . (xv) The connection clamp shall be permanentlly welded to the copper bounded rod to avoid any kind of connectivity loss,.The pre-welded copper bounded rod shall not need any additional clamp for termination. (xvi) The acceptable earth resistance at earth busbar/ test point shall not be more than 0.1 ohm. (xvii) Earth work such as auguring and making good the surrounding area shall carried out in any type of soil. (xviii) The contractor shall submit CPRI India certified document for copper bounded rod to ensure genuineness of material.

(xix) Sign board of mild steel sheet 2 mm thick duly painted with two coats of synthetic enamel paint over a coat of red oxide Zinc chrome primer showing result of earthing shall be fixed near the earth pit after completion as directed by engr -in- charge.
