M&E · Water & drainage
Water and drainage: supply, waste, pumps, tanks — before the ceiling closes
Domestic water, floor and roof drainage, booster and drainage pumps, tanks. Pressure-tested and flushed before concealment. A frequent critical path on factories under FDI projects if left until after plasterboard.
- Risers, floor branches, isolation valves by zone.
- Wet-area, roof, kitchen and WC drainage — falls, access points, traps.
- Pumps, floats, pump boards — live-water commissioning, not a dry spin.
- Chilled-water pipework when in the same HVAC package.
