Fabrication of MS platform in pumping station , MS stairs from platform to ground level, fabrication of base frame, foundation block and saddle block for suction line of newly installed pumping unit no 2 along with allied works at Lift Irrigation St

Fabrication of MS platform and stairs:-Fabrication of platform inside the pumping room at lift irrigation station, Nikowal old by way of providing, fitting and fabrication of 16.5 ft x 4 ft platform made up of MS channel and MS Strip. The platform should be made in L shape with 1 ft x 4 ft of extension on entry side of lift station for easy loading and unloading of materials using chain pulley. The platform should be made up of 100 mm MS C section and 50 x 5 mm MS strips should be welded between theframe made up of MS channels with 25 mm gap between the strips. The sides of 100 mm MS channel should be grouted inside the walls of lift stations for support. Centre supports must be provided and welded at the base of platform to support the weight. Fabrication of MS stairs with the width of 3 ft., the stairs should consists of side channels made up of ISMC 100 mm and fabrication of stairs with 10 inch thread and 9 inch riser. 50 x 5 mm MS strips must be used for construction of thread portion. The stairs must start from the fabricated platform and ends on the floor level at lift irrigation station with bottom end grouted in floor. Painting of fabricated structure with red oxide paint and then with black enamel paint. Painting of pumping unit no. 1 including, motor, pump, suction, delivery and control valves with enamel paint following proper colour code. Fabrication of foundation block and base frame:-Dismantling of the 5 cusecs split casing pumping unit no I (old pumping unit) at lift irrigation station, Nikowal 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. Fabrication of foundation block for the pumping unit by laying of new RCC foundation block of size length – 5 ft x width- 2.5 ft x depth- 3 ft by way of making surface even for laying of new RCC foundation block. Fabrication of iron mesh out of 10 mm TMT bars members placed at an equidistance of 6 inches. 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 with the pumping unit. Fabrication and grouting of 6 number 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 levelling and fastening with foundation bolts. Curing of foundation block for 5 days. Fabrication of new base frame by means of providing and fitting of 4 inch ISMC channel and fabrication of base frame (for foundation of 5 feet length x 2.5 ft width) by means of welding the ISMC channels to form the base frame as per the site requirement. The job includes providing and fabrication of base support for motor and pump with height as per alignment of pump and motor. Holes have to drilled on the base frame in alignment with the foundation bolts. Installation of pump and motor over the base frame with alignment of the pumping unit. The firm should quote rates including rebate on base frame and allied material. Fabrication of saddle block/ anchor block for suction pipe:-Fabrication of saddle block for newly installed pumping unit no 2, by way of excavation of 5 ft- length x 2 ft- width x 3 ft deep pit below the suction pipe. The size of the block above the ground level should be in alignment to the suction pipe. The block shall be filled with rich mixture of concrete and stones 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 load of suction pipe and flow of water. Four number foundation bolts of 3 ft length needs to be embedded in saddle block along the length to hold the suction pipe at different positions. MS channel of 100 mm should be used for clamping suction line at both positions in such a way that suction pipe should rest over the MS channel and other MS channel of same length should be used for fastening of pipe using existing foundation bolts embedded in concrete block. The MS channels should be drilled with holes as per the size and dimensions of foundation bolts. The alignment and position of saddle block should be kept as per the suction line already laid at site. Complete job includes cost of material, welding charges, carriage charges, fabrication charges. The material has to be carried on head load from road side to lift irrigation station. The size can vary as per site conditions. 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.
