Foundation block for pumping unit no 3, modification of delivery arrangement for water diversion to upper and lower water delivery channels along with allied mechanical works at Lift Irrigation Station, Kothey Kalyana old.

Dismantling of the 5 cusecs X 25 HP pumping unit no III at lift irrigation station, Kothey Kalyana old by way of demounting the pumping machinery from the bed plate after removing the pump, motor, electric connections, coupling pulleys, suction and delivery pipes and finally removing the base frame. Breaking the damaged RCC foundation block with the help of Chisel, concrete cutter, electric jack hammer, tools / tackles. Cutting of steel members with the help of cutter step wise during the process of breaking the RCC block and stacking. Completely removal of broken concrete, soil and Tmt bars from pump room in such way that the machinery and electric equipment's of other pumping machinery are not damaged/ effected. Disposal of salvage of dismantled foundation away from pumping room up to the distance of 100 m at such place where irrigation land and water source is not polluted. Laying of new RCC foundation block at new position to make space for installation of new pumping machinery. Fabrication of new foundation of size length – 5 ft x width- 2.5 ft x depth- 3 ft after making surface even for laying of new RCC foundation block. Fabrication of steel mesh out of 10 mm TMT bars members at an equidistant of 9 inches. Laying of 6 inch concrete base at the bottom to level the surface. Placing of fabricated iron mesh in foundation pit and leveling / aligning it with the pumping unit. Fabrication and grouting of 6 No. foundation bolts of size 2.5 ft in foundation block. Laying of RCC foundation block of size 5 ft x 2.5 ft x 3 ft by filling the concrete in the ratio of 1:1.5:3. The size of the block above the ground level should be of original size and alignment in 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 leveling and fastening with foundation bolts. Complete job includes cost of material such as cement, sand, steel, shuttering charges, charges for concrete mixture, vibrator charges and labour charges of skilled as well as semi skilled labour, curing charges. The material has to be carried on head load through fields from road side to lift irrigation station (aerial distance approx. 700 meters). Installation of pump over the foundation using highly skilled labor and alignment of the pump with motor. Providing and fitting of new 200 mm diameter cast iron, flanged foot valve with pressure rating of PN 0.2, the door face should consists of rubber with reinforcement of cotton canvas, flange drilling as per IS:1538 after replacing existing damaged foot valve by cutting rusted nuts, bolts with gas cutting at intake source. Job includes providing of new nuts, bolts and rubber gasket. Providing and fitting of 200 mm diameter sluice valve on delivery side of pumping unit 3 Installed at lift irrigation station by way of cutting existing delivery, the delivery should be fabricated in such a way that water can be diverted to upper channel and lower channel from the delivery line of pump at site and welding of 200 mm diameter plate flanges on both ends. Providing and fitting of flanged ends cast iron sluice valve with PN 1.0 conforming to IS 14846 on delivery side of the pumping unit with rubber gaskets, nuts and bolts on the delivery pipeline of pumping unit no. 3.The delivery branch on lower side towards channel should be provided and welded with flange and fastened with blind flange. Fabrication of delivery pipe outside the pumping station for pumping unit no 4, by way of cutting existing delivery, the delivery should be fabricated in such a way that water can be diverted to upper channel and lower channel from the delivery of pump at site and welding of 250 mm dia plate flanges on both ends. Providing and fitting of 250 mm diameter, flanged ends cast iron butterfly valve valve with PN 1.0 (Kirloskar/ KSB/ L&T valves) on delivery side of the pumping unit towards the upper channel with rubber gaskets, nuts and bolts. Complete painting of pumping machinery of unit no 3 and 4 including pump, motor, suction, delivery, valves with coat of enamel paint as per colour code. Complete job includes cost of material, labour charges, carriage charges of material to lift irrigation station to road side and then carriage of material from road to lift irrigation station on head load ( aerial distance approx. 700 meters) and cost of civil works such as closing of walls broken for passing of delivery pipes. The firm should quote rates including rebate on old damaged valve of pumping unit no 3 and other allied accessories. Note:- The tenderers are requested to visit the site and quote the rate as per site conditions. Any modifications/ alterations of the job, absolutely necessary if required at the time of execution may be done as per actual site conditions.
