Providing fitting and replacement of suction pipe rising main along with its allied works at LIS Khawaskhan.

Dismantling the worn out suction line of unit I & II along with foot valves at LIS Khawaskhan by way of cutting the old rusted nuts, bolts and then dragging/pulling out of the canal along with foot valves using crane/chain pulley block and other tools and tackles required. Then providing and laying and fitting MS suction line of 31 feet (approximately) of 8” dia minimum 6mm thickness with 10 No flanges, 01 No. foot valve (make KSB, Kirloskar, L&T or equivalent) of same dia with required nuts, bolts and rubber sheet joints for unit I & II each along with flange after ensuring the proper alignment by way of fabricating the 02 nos bends of suitable angle with the pump body for each unit. Job also involves digging of earth for construction of anchoring block of 7.0”x3.5”x5’ (approximately) by way of making surface even for laying of new RCC block. Fabrication of steel mesh out of 10 mm steel bars placed vertically and horizontally suitably a distance apart duly welded Laying of 6 inch PC concrete base with 40mm stone aggregate at the bottom to level the surface. Placing of fabricated iron mesh in foundation pit then foundation bolts are to be welded to steel reinforcement of anchoring block in proper alignment and spacing with respect to the suction pipes to be anchored. Filling the concrete in the ratio of 1:2:4. The size of the block may vary slightly as per space availability and ground condition and should be in alignment with respect of suction 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. Anchoring of suction pipes of both the units with requisite nos of MS clamps with 32/40mm MS strip with required nut bolts. Dismantling of delivery line of unit I along with sluice valve after cutting the old rusted nuts and bolts and then extracting out the delivery line from the pump room. P/F of 8” dia MS delivery pipe of 13 feet length along with 05 nos. flanges and 02 no bends and fitting of sluice valve along with nuts bolts and rubber sheet joints for flanges. Extracting the old worn out rising main by way of digging the metalled road 10’ wide (approximately) around the existing rising main of 10”dia. Cutting the rising main in pieces using gas cutter for easy extraction. Then providing /laying and fitting of 25mtrs (approximately) MS rising main of 10” dia with 08nos flanges of same dia and bends required (Minimum 2 bends of 90 degree )with required nuts bolts and rubber sheet joint by way of welding, cutting and realigning the rising main to the existing delivery tank/khul. The job further involves fabrication of the manifold using 12” dia MS pipe of 5feet length approximately by way of welding the two no blind flanges on both the side then joining the one end of delivery line of unit I to the manifold after cutting the one side blind flange and then welding the pipe to make leak proof, joining the delivery lines of units II to the newly fabricated manifold from the side to make it look like Y junction and filling up the excavated material around the periphery of the rising main on the road width. Also construction of 03 no supporting block for rising main of appropriate size with PCC works. Testing of all newly laid pipes, manifold etc. for any sort of leakage and full load and plugging their off. Any component / work left out in advertently but required for installation shall be deemed to be included in the job. Complete painting of suction pipes, delivery pipes and rising main with one coat of primer and two coat of black paints. Complete job includes cost of material, hire charges of welding set, gas cutter/crane/any other tools and tackles required to execute the works, carriage/deployment charge of machinery/material used at LIS Khawaskhan.
