Fabrication of New Pontoon (02 Nos.) in complete aspect and fabrication of floating drum structures (03 Nos.), making of Sheds for Pump -Set on Pontoons to be installed for Monsoon 2026 (08 Nos.) at Bina Project.

Part (A): Fabrication Part

Fabrication of 2 Nos. Pontoon of desired shape and size with MS channel, angle, plate, GI pipe etc, Complete in all respect including shifting of material from the store, fabrication, assembling of all blocks and testing of all blocks for obtaining desired buoyancy as per instruction of Engineer/Site Incharge. Material required for 01 pontoon base channel (100X50X6)-708.4 Kg, Bracing, cleat & clamp etc. Angle (50X50X6mm) 2161.35 kg, MS plate 3.15 mm- 3115.94 Kg. GI pipe 150 mm (40 mtr. Approx)- 900 kg. Total Iron & Steel = 6885.69 Kg each i.e, 6.88 MT) (Iron & steel and gas will be arranged by Bina Project NCL, welding/cutting electrode, welding machine and nut & bolts required for assembling of blocks, will be arranged by the contractor.)

Painting of all blocks of each pontoon with "supply of chloride zinc phosphate red oxide primer paint & two coat painting at the surface of pontoon both inside and outside including cleaning degreasing, de-rusting of the area to be painted complete" as per instruction of EIC (02 Nos. pontoon x 196 Sqm. each)

Painting of all blocks of each pontoon with "supply of anticorrosive rubber paint and two coat painting on inner & outer both side of the surface of pontoon up to 1 mtr. Height complete" as per instruction of EIC (02 Nos. pontoon x 196 Sqm. each)

Fabrication of 03 Nos. floating drum structure (with 12 drums) with cutting, welding, testing of drum and jointing etc. (The dimensions of 01 floating drum structure(LxWxH) is 365cmX180cmX60cm with railing of 365cmX60cm), Material required for 01 floating drum structure is Angle (65X65X6 mm) = 352 kg including 10% wastage, MS plate 6 mm- 170 Kg including 10% wastage. Total quantity of Iron & Steel= 03 Nos. Floating drum structure X 522 KG each = 1566 Kg i.e. 1.57 MT (Approx), (Iron & steel and gas will be arranged by Bina Project NCL, welding/cutting electrode, welding machine

Painting of 03 Nos. floating drum structure with "supply of chloride zinc phosphate red oxide primer paint & two coat painting at the surface" as per instruction of EIC (03 Nos. pontoon x 25 Sqm. Each, Total = 75 Sq. mtr)

Painting of 03 Nos. floating drum structure with "supply of anticorrosive rubber paint and two coat painting on inner & outer both side of the surface" as per instruction of EIC (03 Nos. pontoon x 25 Sqm. Each, Total = 75 Sq. mtr)

Part-(B): Making of shed on Pontoons to be installed for Monsoon 2026

Structural steel work riveted, bolted or welded in built up sections, trusses and framed work, including cutting, hoisting, fixing in position and applying a priming coat of approved steel primer all complete, for Shed on Pump - Motor Set to be installed at Pontoons for Monsoon 2026. (Quantity =198 kg X 8 Nos.+ 10% wastage = 1742.40 Kg i.e 1.74 MT (Approx) shed on pontoon, as per instruction of Engineer Incharge/Site Incharge. ( Iron & steel and gas will be arranged by Bina Project - NCL, welding/cutting electrode and welding machine to be provided by contractor)

Providing and fixing precoated Galvanised iron profile sheets (size, shape and pitch of corrugation as approved by Engineer-in-charge) 0.50mm (+0.05%) total coated thickness with zinc coating 120 grams per sqm as per IS:277, in 240mpa steel grade, 5-7 microns epoxy primer on both side of the sheet and polyester top coat 15-18 microns. Sheet should have protective guard film of 25 microns minimum to avoid scratches during transportation and should be supplied in single length upto 12 meter or as desired by Engineer-in-charge. The sheet shall be fixed using self drilling/self tapping screws of size (5.5 x 55mm) with EPDM seal, complete upto any pitch in horizontal/vertical or curved surfaces, excluding the cost of purlins, rafters and trusses and including cutting to size and shape wherever required. ((Iron & steel and gas will be arranged by Bina Project NCL, welding/cutting electrode, welding machine) (32.4X8 = 226.8 = 260 SqM Approx)
