Providing and Fitting of MS Gantry for extraction of foot valves and suction pipes along with allied works at LIS Rathua

Amount

Design, Fabrication, installation, testing & Commissioning of gantry with 2Ton capacity Chain pulley Block with accessories for extraction of Foot valves/ Suctions Pipes from sump at LIS Rathua. The job involves providing and fitting of MS gantry by way of laying RCC Concrete block of Size (6 ft x 6 ft x 7 ft) adjacent to the suction pipes for anchoring of vertical section. The job involves excavation of trench of size (6.25ft x6.25 ft x 7.25 ft) by excavating soil, removal of excavated material and disposing off the same to a safer distance from working area. Laying of crushed stones of 40mm size throughout the block, laying of one layer of 1:4:8 concrete mass for 100mm depth (approx.), with reinforcement of 10mm dia. TMT steel having mesh size 250 sq.mm throughout the block, laying of 1:1.5:3 concrete mass. Fabrication of 01No. 10.0 ft. height (Approx.) vertical section from 200mm MS pipe. Fabrication of foundation plate of size (425 mm x 425 mm) from 25 mm thick M.S sheet to be welded to one end of vertical member. The job involves drilling of 04 nos. holes of 25mm dia. to M.S support plate and welding the plate to the vertical section pipe along with support braces. Grouting the 04 nos. foundation bolts of size 5 ft long and 25mm dia. properly into the foundation block. The job involves providing and fixing of 2no. tapered roller bearings() alongwith pin of size 100mm dia. along with chuck nut and lock and required number of flanges at a height of approx. 5 ft. from the base in the vertical section pipe. Erection of vertical section by fastening the foundation plate with foundation bolts with nuts. Providing and Installation of ISMB 200 of length 25 ft. (approx.) as cantilever section to be fixed with the top of vertical member with the help of welding/flanges and nut bolts arrangement. Providing and installation of the overhead movable trolley along with chain pulley block of 02T capacity for lifting of foot valves/suction pipes and fixing the mechanism with the help of nut/bolts/welding it with the cantilever section and providing/fitting of steel chain of suitable capacity along with other accessories. The trolley should have the horizontal movement over the cantilever section. Length of the steel chain should be minimum 15 ft for trolley and 15 ft. for chain pulley block. Providing and fixing of a cage made out of 50 mm x 50mm x6mm MS angle and flat to be used as counterweight at the other end of the cantilever section. The cantilever also has to be provided with fixed suitable trusses made out of 75 mm dia. GI pipe for strengthening of the overall gantry. The job includes the cost of material, labour charges for fabrication of overhead gantry, cantilever type near suction pipes, hiring charges of welding set & Oxy-acetylene gas equipment, DG set, hiring of crane/tripod stand charges, transportation charges, skilled/semiskilled labour charges at the site of installation.
