Drilling of Bore well with Rotary Rig per RM Drilling of Bore hole (which may be carried out by pilot bore hole) to a finished dia of 200/225/300/350/450 mm hole (for insertion of 110/140/160/180/200mm PVC Pipe / 175/200mm PVC Blue casing pipe) by Rotary drilling rig in all formations suitable for Rotary drilling such as alluvium, Loamy, clayey, sandy, burried channels, highly disturbed and bouldary zones high sheared and fractured zones followed by jointed to massive soft, medium rock, all formations typical and suitable for rotary drilling etc. including insertion of casing pipe, couplings, cap, plug fixation, and including filling the peripheral gap with rebullied pebbled gravel packing, 1 bore development, conducting yield test, and all other required in the fixation of pipes assembly etc. but excluding the cost of casing pipe, couplings, dummys, clamps etc., as recommended by the departmental Geologist. The bore should be developed with compressor air until clear water free from sand and other materials continuously discharged. The size of gravel used for gravel packing should be as per ISI specification used for rotary tube well. The 117 pebbled gravel packing should be carried out in such a way that the theoritical quantity consumed completely. The entire work to be carried out as per I.S. 2800 Part I & II of 1979 and including cost of all materials and all labour charges and excluding all taxes etc., as per SOR 2026-27
