Design, fabrication and construction/ erection CGI shed of 10’x 10’x 10’ for drought lift irrigation station at Khairi by dismantling the suction and delivery pipelines of drought pumps, lifting of existing drought pump from place of installation using crane and other tools and tackle required. Excavation of 08 nos trenches of size 1.5’x1.5’x3’ at appropriate places for erection of vertical sections and (1’widex1’height) up to the total length of all four side walls for laying of plinth and disposing of the excavated material to the permissible dumping site. Welding of 1’x1’ m s sheet of 4mm thickness at the bottom of the vertical post filling of plinth up to the height of 2’ (1’ in the ground and 1’above the ground) and erection of vertical post of 75x50 mm channel by Laying of 1:3:6 grade (1 cement: 3 sands: 6 aggregates) all along the plinth. Levelling of surface 10’x 10’ by filling/ compacting the earth, laying of layer of stones and compacting. Laying of 1:3:6 grade (1 cement: 3 sands: 6 aggregates) on the 10’x 10’ area up to required height. Also fixing the foundation bolts 06 nos of appropriate size at suitable place of the floor for anchoring the base frame for diesel engine driven pump set. Curing of concrete structure for 5 days. The frame of the shed should be fabricated and welded out of 50 x 50 x 5 mm MS iron angle. The sides of frame must be grouted in concrete. Three number supports of 50 x 50 x 5 mm MS angle iron have to be welded between each side wall of frame. Two nos cross members must be welded of same size to support the roof of the shed. Providing and fitting of 0.5 mm colour coated profile sheet with aluminium zinc coating of ISI mark on the fabricated structure with nut, bolts/hooks and washers. The shed must be provided with door of suitable width and height as per size of drought pump, for easy removal of pumping machinery for repairs and maintenance. The door should have heavy duty latch for locking arrangement. The shed must be provided with window of 3’width x 4’ height should be fabricated on side. The shed must have provision for inlet of suction pipe and outlet of delivery pipes. The roof of shed must be inclined from one side to prevent water logging. The appropriate arrangement for hanging/fixing of the fuel tank must be made in the shed. Installation of drought pump set inside the newly fabricated shed using crane. Modification in suction and delivery pipelines by providing, fitting, welding and laying of MS suction pipeline of 200 mm diameter 10 feet (approximately) including fabrication and fitting of 01 no bends and 04 nos flanges of same dia from sump to pump and then then providing and fitting of 20 feet delivery pipe of 200mm dia from pump to existing delivery line after relaying the pipe as per new location of pump set with requisite bends (02 nos) fabricated to required angle and welding of flanges to their ends. Providing and fitting of rubber gaskets between each MS flange joint. Fastening of each length of suction and delivery pipe with hexagonal nuts and hexagonal bolts. The job includes refilling of earth after laying of pipeline. Providing and fitting of 40 ltr oil tank for engine, the tank must be leak proof with sufficient inlet of diesel and have standard outlet for connecting diesel pipe to engine. Providing and fitting of diesel pipe from oil tank to engine. Complete painting of suction pipes, delivery pipes by way of rubbing / scratching the dirt / grease, painting with one coat of primer and two coats of standard quality paint. Electrification of shed by providing and fitting of one no 50 watt LED light inside the shed, 01 no led bulb and one no socket point. Providing and fitting 1/1.5 mm2 copper cable for electric connections and all cables must be properly covered with PVC conduit and should not have any loose connections. Providing and fitting of 01 no DP on/off switch, 03 no on / off switches for light/socket point, switch board and bulb holder etc at drought station Khairi. Complete job includes cost of material including rebate on old parts , consumable, handling, labour charges for both skilled /semi-skilled labour and hiring charges for Crane, welding/ cutting set, shuttering charges, tools and tackles required during the execution of the job at site. 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.
