This item includes costof all inputs of designing, labour for fabricating and installation of aluminium grid,installation of glazed units, T&P, scaffolding and other incidental charges includingwastages etc., enabling temporary structures and services, cranes or cradles etc.as described above and as specified. The item includes the cost of getting all thestructural and functional design including shop drawings checked by a structuraldesigner, dully approved by Engineer-in-charge.The item also includes the cost of all mock ups at site, cost of all samples of theindividual components for testing in an approved laboratory, field tests on theassembled working structural glazing as specified, cleaning and protection till thehanding over of the building for occupation. In the end, the Contractor shall providea water tight structural glazing having all the performance characteristics etc. allcomplete as required, as per the Architectural drawings, as per item description,as specified, as per the approved shop drawings and as directed by the Engineerin-Charge.Note:- 1. The cost of providing extruded aluminium frames, shadow boxes, extrudedaluminium section capping for fixing in the grooves of the curtain glazing andvermin proof stainless steel wire mesh shall be paid for separately under relevantitems under this sub-head. However, for the purpose of payment, only the actualarea of structural glazing (including width of grooves ) on the external face shallbe measured in sqm. up to two decimal places.Note:-2. The following performance test are to be conducted on structural glazingsystem if area of structural glazing exceeds 2500 Sqm from the certified laboratoriesaccreditated by NABL(National Accreditation Board for Testing and CalibrationLaboratories), Department of Science & Technologies, India. Cost of testing ispayable separately. The NIT approving authority will decide the necessity of testingon the basis of cost of the work, cost of the test and importance of the work.Performance Testing of Structural glazing systemTests to be conducted in the NBL Certified laboratories1.
