| 3 | Description:- Providing and fixing of self supported arch shaped mechanically seamed trussless galvalume\rroofing system such as proflex or similar as approved by Engineer-in-charge, made of superior quality structural\rgrade steel, having 350 MPA yield strength, pre coated galvalume sheet as per ASTM A 792 M of base thickness\r1.0mm (tolerance +/- 0.02mm) with minimum coating mass as per AZM 150. Total coated thickness 1.075mm\r(tolerance +/- 0.02mm). Roofing should be designed as per ASCE 7-20 international building code 2002. The\ranalysis shall be carried out for span and center arch-rise considering the required live load, wind load, dead load\rand the seismic factor. The roof panel formation shall be done as per the required length and curvature using\rhydraulic profile machine to give it the trapezoidal shape in required curvature. In this process the width of the\rsheet reduces from 0.914 meter to 0.61 meter (tolerance +/- 0.02m). The roof panel shall be lifted using a\rsuitable crane and using a spreader bar and sling evenly placed to ensure no distortion of the panels during\rlifting and placing. The crane shall hold/support the panel till the alignment is done and completed using a plumb\rand a water tube and bolted into beam. These curved panels have interlocking formation and are crimped\rtogether using mechanical seaming machine, which imposes a load of approximately five tones to ensure the\rseaming of required rigidity. After seaming, a clear epoxy lacquer is applied on the inner side of panel end in\r15cm width to from a protective layer between panel and concrete beam. These panels are installed over existing\rwater proof concrete gutter-beams having beveled edge to receive (support) curved panels. Beam shall design\rfor arch reaction and vertical loads. Plaster shall not be applied on the beam. Schmidt Hammer test of the\rconcrete should be carried out before erection to ensure that the anchor bolt can be securely fixed on support. In\rcase of steel structure a steel runner plate of 6mm thickness and G.I. sheet gutter of suitable size shall be\rprovided for installation of panels, G.I. anchor bolt of required sizes and type with G.I. washer and neoprene\rwashers shall be provided as per design. After installation of panels, trapezoidal voids are created between\rgutter-beam and panels which should be covered by a flashing fabricated or brick masonry which is to be paid\rseparately. Area of this roof shall be measured along the periphery of hem-top between end to end of panels.\rRidge and valley shall not be taken into consideration for measuring length transverse to periphery. The rate\rincludes supplying, fixing, loading unloading, hire charges of all plants machineries, anchors, fasteners, washers,\rbolts, epoxy, paint and all wastage etc. complete. The rate includes supplying and fixing Accessories and fixtures\rlike hangers/clamps for installation of lighting/fixtures/utility/duct as per requirement.
