Earthwork in excavation by mechanical means ( hydraulic excavator) in trenches for foundations, drains, pipes, cables etc.( notexceeding1.5 mtr in width ) and for shafts, wells,cesspits and the like ramming of bottoms lift upto 1.5 mtetr , including getting out excavated earthand disposal of excavated as ,All kinds of Soil

Providing and welding of medium ERW MS?GI pipes by laying of rising main in the excavated trenches , rocky surface and open as per site condition, leveling, cutting aligning the pipe, circumference welding of 125 mm dia pipe with ISI marked welding rods to fill the groves between the pipes. The welding to be done by special / skilled workman, handling of pipes with proper tools/ tackles employing semiskilled workman. Tools and tackles can be tripod stand, chain pulley blocks etc for lowering ang raising of pipe and workability, proper and edge leveling.The deviation / bends are to be fabricated from available pipes. The complete job includes cost of pipes, welding rods, gas for cutting and charges of equipment, tools, skilled and semi-skilled labour.
