Reinforcement Material Supply and Refractory Gunning Application for Space Centre Infrastructure

This tender, under Bid Number GEM/2026/B/7758857, is issued by the Indian Space Research Organisation, a key entity within the Department of Space. The Satish Dhawan Space Centre Shar is the specific office managing this procurement. The opportunity involves the "Supply of reinforcement material and application of gunning" with a Bid End Date of 16-10-2026 at 4:00 PM and a Bid Start Date of 15-10-2026 at 11:00 AM, making it crucial for interested parties to submit their proposals within this timeframe. The detailed Bill of Quantities (BOQ) specifies the provision and installation of various SS310 grade components, including M16 anchor fasteners with 20mm diameter sleeves, 8mm diameter rods of standard 6m length, and 2D V anchors of 6mm diameter in both 30mm and 50mm heights. Furthermore, the tender encompasses the supply of meltextract SS310 fiber with specific length (20-25mm) and width (0.38-0.51mm) parameters. Crucially, the scope of work extends to the dismantling of existing gunning grade refractory lining on JDD ridge wedge floor and wall portions, followed by the meticulous installation of M16 anchor fasteners on JDD floor and wall portions. A significant part of the process involves sand blasting 25mm thick Mild Steel plates, thorough cleaning of the sand blasted surface, and the application of an anti-corrosive coat. The tender also requires the welding of SS310 3D V anchors of 155mm and 60mm heights to JDD ridge wedge portions, as well as the welding of SS310 2D V anchors of 30mm height to the JDD SS310 grid at JDD floor divergent portion-2 and walls, and 50mm height anchors to the JDD SS310 grid at JDD floor divergent portion 1. Finally, the successful bidder will be responsible for the application of CUMICRETE CA 392G gunning grade refractory cement on JDD ridge wedge floor and walls, including necessary testing. The total quantity for this comprehensive project is listed as 245807 units.
