Dismantling of old wornout HC pump at pumping station Kaghote of same capacity by way of disconnecting of all incoming electrical connections, decoupling of pump and motor and then unfastening from base frame, suction and delivery . Cutting of worn out suction and delivery bends, pipes, dismantling of old unserviceable sluice valves, reflux valves fitted with suction/delivery lines, plugging of open end of delivery pipe line near manifold by Fabrication/fitting of blind flange of suitable thickness with rubber gasket, nuts, bolts etc. to withstand the pressure as well as velocity head created during running of other pumping units. Cutting of base frame from RCC foundation block with gas cutting by using oxygen acetylene gas. Dismantling / breaking of old existing RCC block by way of deploying skilled and un skilled labour by using pneumatic hammer, high carbon chisels and other tools and tackles etc. up to the depth of approx. 2 meters and cutting of wornout steel mesh. The job includes earthwork in bulk excavation around the foundation block on each of the four sides of the block up to the depth of about two meters so as to form a size of 8’x4’x6’.Dumping of excavated material outside the pump room at a distance of 100 meters approximately. Providing and fabrication of 6 no. foundation bolts of suitable diameter one meter long by threading them at one end and making of anchor to other end. Laying of bed concrete of 1:4:8 mix using 20 percent aggregate, laying of RCC of 1:1.5:3 mix including supply/fixing of form work / shuttering, aggregates, sand and cement, reinforcement steel from 12mm complete with cutting, bending, placing in position and binding, angle iron for supporting / alignment base frame, welding, placing of foundation bolts with base frame and making proper alignment of base frame horizontally as well as longitudinally, deployment of vibrator, mixer, welding set, tools and tackles etc. and curing complete. Job further includes dragging of pump motor set from the stacking place and then placing them on the base frame by manual labour and other tools and tackles. Leveling of pump motor set on the base frame by using laminated sheet, strips and coupling thereof. Laying of 150mm dia GI suction and 100mm θ GI delivery pipe lines to the pump set by providing and cutting of 150 / 100 mm dia GI pipe as per site requirement in the convenient lengths with the help of oxygen acetylene gas. The cut edges shall be grinded with grinder to give them a smooth and even surface and then laying, aligning, welding of suction and delivery pipes in continuous weld including providing, fabrication and fitting of 150 / 100mm dia MS bends, flanges, expanders, reducers, gaskets, as per requirement, providing and fitting of 150mm dia CI sluice valve one no. alongwith nut, bolts, flanges, gaskets etc. on the suction side and cast steel sluice valve and NRV with bypass system one no. each including nuts, bolts, gasket, flanges to the delivery pipe of pump set. Job further includes cutting of manifold and then making gas welded joint of delivery pipe end with manifold using oxygen acetylene gas system including cost of gas, suction delivery flanges etc. and connecting with manifold. The weld should free from below hole to have leak proof water tight joint. Job includes installation of 140 ampere LT control panel Providing / fitting of 250 ampere MCCB-01no. of Havells / L&T or other equivalent make, on the board of the pump room by replacing damaged MCCB alongwith nuts, bolts and thimbles. Job further includes providing and laying of 95mm2 rating copper cable confirming to ISI standard from bus bar to panel and further upto motor as per site requirement approx. 40 meters in length alongwith 185mm sq. aluminum cable 4 core armoured from transformer to pole and from pole to voltage stabilizer approximately 35 meters in length complete with thimbling and insulation material. Job also includes testing of pump motor set with allied accessories on no and on full load. Complete job includes cost of material and machinery, transportation charges, manual carriage charges, skilled and unskilled labour charges, hire charges of tools and tackles etc. (complete job).
