using coarse aggregate and fine aggregate derived from natural sources, portland pozzolana / ordinary portland /portland slag cement, admixtures in recommended proportions as per is: 9103 to accelerate / retard setting of concrete, to improve durability and workability without impairing strength; including pumping of concrete to site of laying, curing, carriage for all leads; but excluding the cost of centering, shuttering, finishing and reinforcement as per direction of the engineer-in-charge; for the following grades of concrete. note: extra cement up to 10% of the minimum specified cement content in design mix shall be payable separately. in case the cement content in design mix is more than 110% of the specified minimum cement content, the contractor shall have discretion to either re-design the mix or bear the cost of extra cement all works upto plinth level concrete of m30 grade with 52.00 minimum cement content of 350 kg /cum all works above plinth level concrete of m30 grade with 39.00 minimum cement content of 350 kg 4.1 4.1.1 5 5.1 providing and laying factory made precast concrete solid blocks of 200 mm thickness of grade m10 from approved manufacturer in superstructure above plinth level up to floor v level cement mortar 1:6 (1 cement : 6 coarse sand) sub total non schedule items providing and fixing of self supported arch shaped mechanically seamed trussless galvalume roofing system such as proflex, spider/equivalent , made of superior quality structural grade steel, having 350 mpa yield strength, pre coated galvalume sheet as per astm a 792 m of base thickness 1.4 mm to 1.6 mm ( tolerance +/- 0.02mm) with minimum coating mass as per azm 150. total coated thickness 1.45 mm to 1.65 mm (tolerance +/- 0.04mm). roofing should be designed as per asce 7-20 international building code 2002. the analysis shall be carried out for span and center arch- rise considering the required live load, wind load, dead load and the seismic factor. the roof panel formation shall be done as per the required length and curvature using hydraulic profile machine to give it the trapezoidal shape in required curvature. in this process the width of the sheet reduces from 0.914 meter to 0.61 meter (tolerance +/- 0.02m). the roof panel shall be lifted using a suitable crane and using a spreader bar and sling evenly placed to ensure no distortion of the panels during lifting and placing. the crane shall hold/support the panel till the alignment is done and completed using a plumb and a water tube and bolted into beam. these curved panels have interlocking formation and are crimped together using mechanical seaming machine, which imposes a oad of approximately five tones to ensure the seaming of required rigidity. after seaming, a clear epoxy lacquer is applied on the inner side of panel end in 15cm width to form a protective layer between panel and concrete beam. these panels, are installed over existing water proof concrete/ms gutter beams having beveled edge to receive (support) curved panels. beam shall design for arch reaction and vertical loads. plaster shall not be applied on the beam. schmidt hammer test of the concrete should be carried out before erection to ensure that the anchor bolt can be securely fixed on support. in case of steel structure a steel runner plate of 6mm or more (as per design requirement) thickness and g.i sheet/ms sheet gutter of suitable size(ms shall be paid seperatly in respectively agreement item) shall be provided for installation of panels, gi anchor bolt of required sizes and type with g.i washer and neoprene washers shall be provided as per design. after installation of panels, trapezoidal voids are created between gutter-beam and panels which should be covered by a flashing fabricated or brick masonry which is to be paid separately. area of this roof shall be measured along the periphery of hem-top between end to end of panels. ridge and valley shall not be taken into consideration for measuring length. transverse to periphery. the rate includes supplying, fixing, loading unloading, hire charges of all plants machineries, anchors, fasteners, washers, bolts, epoxy, paint and all wastage etc. complete. the rate excludes supplying and fixing accessories and fixtures like: hangers/clamps for installation of lighting/fixtures/utility/duct ,turbo ventilators etc. as per requirement. this item shall be executed only by the approved supplier or authorised installer, which has all require manufacturing machineries and necessary expertise. agency shall be entirely responsible for the damage of the same during transport, installation and even after installation. note:--agency will submit roof stability certificate having 25 years of warrenty from original equipment manufacturer (oem)/approved supplier or authorised installer. entire roofing installation carried out at minimum 8 m height at end and 11 m at center. nothing extra will be paid for this activity. with sheet of (base matel) thickness 1.4 to 1.6 mm
