(b) Fabricating and supplying serrated M.S. hot dip galvanised / Aluminium alloy of 6005 T5 brackets of required sizes, sections and profiles etc. to accommodate 3 Dimentional movement for achieving perfect verticality and fixing structural glazing system rigidly to the RCC/ masonry/structural steel framework of building structure using stainless steel anchor fasteners/ bolts, nylon seperator to prevent bimetallic contacts with nuts and washers etc. of stainless steel grade 316, of the required capacity and in required numbers (c) Providing and filling, two part pump filled, structural silicone sealant and one part weather silicone sealant. (d) Providing and fixing in position flashings of solid aluminium sheet 1 mm thick and of sizes, shapes and profiles, as required as per the site conditions, to seal the gap between the building structure and all its interfaces with curtain glazing to make it watertight.

(e) Making provision for drainage of moisture/ water that enters the curtain glazing system to make it watertight, by incorporating principles of pressure equalization, providing suitable gutter profiles at bottom (if required), making necessary holes of required sizes and of required numbers etc. complete. This item includes cost of all inputs of designing, labour for fabricating and installation of aluminium grid, installation of glazed units, T&P, scaffolding and other incidental charges including wastages etc., enabling temporary structures and services, cranes or cradles etc. as described above and as specified. The item includes the cost of getting all the structural and functional design including shop drawings checked by a structural designer, dully approved by Engineer-incharge. The item also includes the cost of all mock ups at site, cost of all samples of the individual components for testing in an approved laboratory, field tests on the assembled working structural glazing as specified, cleaning and protection till the handing over of the building for occupation. In the end, the Contractor shall provide a water tight structural glazing having all the performance characteristics etc. all complete, complying with the relavant standard specification and as directed by the departmental officers.

Providing, assembling and supplying of laminated glass panels for SKYLIGHT using heat Strengthened clear Glass and toughened glass sandwiched using 1.52 PVB layer. The Glass of approved colour, size and shape as required shade all complete for the required performance, as directed by the Engineer - in - Charge. The heat strengthened clear glass having properties as U value of 4.20 to 5.50 W/m2 or lower degree K etc., Solar heat gain coefficient less than or equal to 0.35. The sandwich panels shall be assembled in the factory/workshop of the glass processor. The certificate obtained from approved agency should be produced for heat soak test for clear glass. For payment, only the actual area of glass on face # 1 of the glass panels (excluding the areas of the grooves and weather silicone sealant) provided and fixed in position, shall be measured in sqm. all complete, complying with the relavant standard specification and as directed by the departmental officers.
