25.2 : Designing, fabricating, testing, protection, installing and fixing in position semi(grid) unitized system of structural glazing (with open joints) for linear as well ascurvilinear portions of the building for all heights and all levels, including:a) Structural analysis & design and preparation of shop drawings for the specifieddesign loads conforming to IS 875 part III (the system must passed the proof testat 1.5 times design wind pressure without any failure), including functional designof the aluminum sections for fixing glazing panels of various thicknesses, aluminiumcleats, sleeves and splice plates etc. gaskets, screws, toggles, nuts, bolts, clampsetc., structural and weather silicone sealants, flashings, fire stop (barrier)-cumsmokeseals, microwave cured EPDM gaskets for water tightness, pressureequalisation & drainage and protection against fire hazard including:b) Fabricating and supplying serrated M.S. hot dip galvanised / Aluminium alloy of6005 T5 brackets of required sizes, sections and profiles etc. to accommodate 3Dimentional movement for achieving perfect verticality and fixing structural glazingsystem rigidly to the RCC/ masonry/structural steel framework of building structureusing stainless steel anchor fasteners/ bolts, nylon seperator to prevent bimetalliccontacts with nuts and washers etc. of stainless steel grade 316, of the requiredcapacity and in required numbers.c) Providing and filling, two part pump filled, structural silicone sealant and onepart weather silicone sealant compatible with the structural silicone sealant ofrequired bite size in a clean and controlled factory / work shop environment ,including double sided spacer tape, setting blocks and backer rod, all of approvedgrade, brand and manufacture, as per the approved sealant design, within and allaround the perimeter for holding glass.d) Providing and fixing in position flashings of solid aluminium sheet 1 mm thickand of sizes, shapes and profiles, as required as per the site conditions, to seal thegap between the building structure and all its interfaces with curtain glazing tomake it watertight.e) Making provision for drainage of moisture/ water that enters the curtain glazingsystem to make it watertight, by incorporating principles of pressure equalization,providing suitable gutter profiles at bottom (if required), making necessary holesof required sizes and of required numbers etc. complete. 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. Performance Laboratory Test for Air Leakage Test (-50pa to – 300pa) & (+50pa to+300pa) as perASTM E-283-04 testing method for a range of testing limit 1 to 200 mVhr”2. Static Water Penetration Test. (50pa to 1500pa) as per ASTME- 331-09 testingmethod for a range up to 2000 ml.”3. Dynamic Water Penetration (50pa to 1500pa) as per AAMA 501.01-05 testingmethod for a range upto 2000 ml”4. Structural Performance Deflection and deformation by static air pressure test(1.5 times desing wind pressure without any failure) as per ASTME-330-10 testingmethod for a range upto 50 mm”5. Seismic Movement Test (upto 30 mm) as per AAMA 501.4-09 testing method forQualitative test” Tests to be conducted on site6. Onsite Test for Water Leakage for a pressure range 50 kpa to 240 kpa (35psi)upto 2000ml”

25.6 : Providing and supplying Spandrel Glass Panels comprising of 6 mm thick heat strengthened monolithic Providing and supplying Spandrel Glass Panels comprising of 6 mm thick heat strengthened monolithic float glass of approved colour and shade with reflective soft coating on surface # 2 of approved colour and shade so as to match the colour and shade of the IGUs in the vision panels etc., all complete for the required performance as specified, as per the architectural drawings, as per the approved shop drawings, as specified, and as directed by the Engineer- in - Charge. For payment, only the actual area of glass on face # 1 of the glass panels (but excluding the area of grooves and weather silicone sealant) provided and fixed in position, shall be measured in sqm. (Payment for fixing of Spandrel Glass panels in the curtain glazing is included in cost of relevent item*).(ii) Coloured tinted float glass 6mm thick substrate with reflective soft coating on face #2, + 12mm Airgap + 6mm Heat Strengthened clear Glass of approved make having properties as visible Light transmittance (VLT) of 25 to 35%, Light reflection internal 10 to 15%, light reflection external 10 to 20%, shading coefficient (0.25 - 0.28) and U value of 3.0 to 3.3 W/m2 degree K etc. The properties of performance glass shall be decided by technical sanctioning authority as per the site requirement.
