Providing/Replacement, Testing and Commissioning of 03 cusec x 10 meter pump set along with its allied works of Unit-I & Construction of new 100 KVA electric substation along with its allied infrastructure including its testing & commissioning at LIS KhawasKhan.

Dismantling of the 2.5 cusec end section HC pump coupled with 12.5 HP motor from its foundation after disconnecting the electrical connection of unit-I at lift irrigation station Khawas Khan by way of cutting the old rusted nuts and bolts, decoupling the motor pump from coupling pulleys, suction joints, delivery joints, attachment pipes and then extracting out the pump and motor from the pumping room using tools and tackles and manual labour. Digging out the old foundation block and then extracting out the base frame after cutting the nuts from foundation bolts using the electric cutter /gas cutter. Breaking the old RCC foundation block (4.5’ x 2.5’ x 3.5’) with the help of chisel, concrete cutter, electric jack hammer and other tools / tackles. Cutting of steel members with the help of cutter step wise during the process of breaking the RCC block and stacking. Complete removal of broken concrete, soil and TMT bars from pump room in such way that the machinery and electric equipments of other pumping machinery are not damaged/ effected. Disposing of the excavated material to a distance not less than 100mtrs (approx.) from the pump room at such a place where irrigation land and water source is not polluted. Laying of new RCC foundation block of size 4 ft x 3 ft x 4 ft approx. (as per size of the new base frame) by way of making surface even for laying of new RCC foundation block. Fabrication of steel mesh out of 10 mm steel bars placed vertically and horizontally at an equidistance of 6 inches duly welded on 40 mm MS angle outer frame. Laying of 6 inch concrete base at the bottom to level the surface. Placing of fabricated iron mesh in foundation pit and levelling / aligning it as per the new base frame. The job may include any other fabrication work required for proper fitting/alignment of pumping unit as per site conditions. The foundation bolts are to be welded to steel reinforcement of foundation block in proper alignment and spacing with respect to base frame properly levelled and sealed to the required position. Placing of base frame on newly constructed RCC foundation block and the already welded 06 No. foundation bolts of size 2.5 ft in foundation block. Laying of RCC foundation block of size 4 ft x 3 ft x 4 ft approx. (as per size of the base frame) by filling the concrete in the ratio of 1:1.5:3. The size of the block may vary slightly as per space availability and ground condition and should be in alignment with respect of suction and delivery pipes. The block shall be filled with rich mixture of concrete with using vibrator for compaction. The entire block as one unit is to be laid in such a way that it can damp all types of mechanical vibrations created by dynamic load of pumping unit without causing any defect to the pumping unit as well as to the block itself. Fixing of the base frame after levelling and fastening with foundation bolts. Complete job includes cost of material such as cement, sand, steel, form work, charges for concrete mixture, vibrator charges and labour charges of skilled as well as semiskilled labour, curing charges. The job includes Providing, Fitting, Installation, Testing and commissioning of new Raw water mixed flow 03 cusec discharge x 10 meter head pump with motor of 20 HP or compatible to the size of pump, coupling pulley and base frame at Lift irrigation station Khawas Khan. Make of Pump: Kirloskar, KSB, L&T or any other ISI standard Type of Pump: Mixed flow pump (end suction) Make of Motor: Kirloskar, GEC, Mather Plant or any other ISI standard Material of construction:- Impeller: Bronze/ Stainless Steel Pump Shaft: Carbon Steel Base frame: Mild steel Shifting of pumping unit to Lift irrigation station Khawas Khan by way of mechanical transport. Unloading of pumping unit at roadside using crane/ manual labour. Carriage of pumping unit to pump room by manual labour. The base frame should be fabricated out of MS channels of totally welded construction and of sturdy design, adequate dimensions having true and machined surface suitable to withstand load and vibrations of the pumping unit. Base frame should have holes for fastening motor and pump. The base frame must be levelled to avoid any misalignment of pumping machinery. Fitting and Installation of motor, pump with coupling pulley and then fitting on base frame with help of skilled manual labour using tools and tackles. Fitting the suction and delivery line to the pump body by P/F of rubber sheet joints along with new nuts, bolts and washer required after ensuring the proper alignment of suction and delivery line and if required amendment in manifold by way of fabrication, cutting /welding of required sizes of flanges/pipes. Giving all the electrical connection from motor to starter by P/F of thimbles of appropriate rating/sizes and insulation complete at site. Complete job. includes cost of material, consumable, handling, loading, unloading, transportation charge, labour charges for both skilled/semi-skilled labour and hiring charges for crane, tripod stand, tools and tackles required during the execution of the job at site. The job also includes shifting of the dismantled pumping machinery along with base frame to road side loading them in mechanical transport and transporting to divisional store at Canal Road, Jammu or any other requisite place desired by the executing authority including unloading and placing properly. Complete job includes cost of material, consumable, handling, loading, unloading, transportation charge, labour charges for both skilled /semi-skilled labour.
