Earth work in excavation by manual means in trenches for foundation, drains,pipes, cables etc. (not exceeding 1.5 m in width) and for shafts, wells, cesspits and the like not ramming of bottoms lift up to 1.5m, including getting out excavated earth and disposal of surplus excavated earth as directed within a lead of 50 mts. a)All kind of Soil 70%

b)Ordinary rock 30%

Providing and welding of medium ERW MS pipe by laying of the rising main in the excavated trenches rocky surface and open as per site condition, leveling, cutting alligning the pipe, circumferential welding of 125/100 mm diameter pipe of 5mm thick with one root layer and two additional layer with 3.14mm and 4mm ISI marked MS 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 semi-skilled works man. Tools/tackles can be tripod stand,chain pulley blocks etc for raising and lowering of pipes and work ability, proper alignment and edge leveling. The initial tack welding and final welding to be perfect circumferential butt welding joints removal of slag before new lay in place and afterwards defects in the welds to be rectified by filling of cavities etc. 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. a)125 mm dia (Medium Class-B)

b)100mm dia (Medium Class-B)

Filling available excavated earth (excluding rock) in trenches, plinth, sides of foundations etc. in layers not exceeding 20cm in depth, consolidating each deposited layer by ramming and watering, lead up to 50 m and lift upto 1.5 m.
