Design, fabrication and construction of CGI shed along with replacement of suction delivery pipes for drought lift irrigation station at Seelam

Design, fabrication and construction of CGI shed along with replacement of suction delivery pipes for drought lift irrigation station at Seelam.

Design, fabrication and construction/ erection CGI shed of 10’x 10’x 10’ for drought lift irrigation station at Seelam 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 2’x2’x3’ at appropriate places for erection of vertical sections and by doing earth work of (1’wide x1’depth) up to the total length for 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 ISMC 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. Two number centre supports of 50 x 50 x 5 mm MS angle iron have to be welded between each side wall of frame. Two no.s purlin 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 the fuel tank must be made in the shed. 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 Seelam Installation of drought pump inside the newly fabricated shed using crane. Connecting suction and delivery pipelines. 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. Providing, fitting, welding and laying of MS suction and delivery pipeline of 150 mm diameter of min 5 mm thickness 40 feet in pieces from sump to pump and then from pump to delivery point. Removing of damaged/ rusted suction pipeline from installed position by way of excavation of earth up pipe level and dismantling of existing suction and delivery pipeline by way of cutting rusted, damaged nuts, bolts with gas welding. Providing, fitting of 02 number MS plate flanges of 150 mm internal diameter with suction pipe at different lengths. Welding of the flanges at the ends of pipes with double layered welding to avoid any leakages as per site conditions. Fabrication of two number MS long bend of required angle as per alignment of suction and delivery pipelines from 150 mm diameter MS Pipe with welding of 150 mm diameter MS plate flanges on both ends of bend. 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. Designing and fabrication of angle iron structures to support the delivery and suction pipeline. 50 x 50 x 5 mm angle iron should be used for fabrication. The structure should be properly grouted in concrete to support the load and vibrations of delivery pipeline. Painting of complete pipeline with one coat of red oxide primer and black paint. Painting of drought pump with enamel paint. Complete job includes cost of material, consumable, handling, labour charges for both skilled /semi-skilled labour and hiring charges for Crane, 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 including the rebate on old material 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.
