Pipe (Medium Class, conforming to IS:1239) railings in three horizontal rows on both sides of the stairs and the entire 1.0 m wide balcony. Vertical posts for the railing shall be securely grouted into the RCC at intervals not exceeding 1.2 m, finished with smooth-welded joints and silver/anti-corrosive paint. Spiral G.I. Ladder & Landings: Fabrication and fixing of a 0.5 m wide Industrial G.I. Ladder extending from the Pump House operating floor down to the Intake Well Raft. The ladder shall be constructed using 50x50x6 mm Angle Iron side-rails with 20 mm dia. ribbed MS/GI rounds as anti-skid rungs. To ensure structural stability, the ladder shall run spirally inside the well, supported by Intermediate R.C.C. Landings at every 2.5 m to 3.0 m height. Structural Supports: Each landing and the ladder frame shall be firmly anchored using G.I. Channels (ISMC series) and vertical posts spaced at intervals of no more than 1.0 m. The base of the ladder shall be securely fixed into a dedicated R.C.C. Foundation Block at the raft level. All steel components used in the well interior must be Hot-Dip Galvanized or treated with three coats of coal-tar epoxy to resist constant humidity and corrosion. Finishing: Supply and laying of premium quality 20mm to 25mm thick polished Kota Stone of approved size and shade for the Pump House floor and 1.0m wide balcony. Stones shall be laid over a 20mm thick base of cement mortar (1:4), true to line and level. Joints shall be filled with matching cement slurry and finished with fine machine polishing (min. 3-4 rounds) including edge rounding (moulding) for the balcony edges to ensure a smooth, slip-resistant finish.Doors & Windows: Fabrication and fixing of heavy-duty door and window frames using 50x50x5 mm M.S. Angle Iron (IS:2062). To prevent corrosion in the high-moisture intake environment, all steel sections shall be treated with Epoxy-based Zinc Rich Primer and finished with Automotive-grade Industrial Enamel Paint. Shutters shall be partly panelled with 6mm thick Aluminum Composite Panels (ACP)—which are lightweight, rust-proof, and weather-resistant—and partly glazed with 6mm thick Wired Glass (Safety Glass) to withstand vibrations and impact.
