Definition
A suspended ceiling is a second ceiling hung below the structural slab on a metal grid, made of gypsum board or removable tiles. It hides services and houses lighting and AC.
Why it matters on a project
The void between slab and ceiling must fit ducts and pipes, so it is coordinated with the section and MEP routes before work starts.
Measurement and pricing
Measured in square metres; bulkheads and openings in linear metres or by number.
Worked example
A 4 × 5 m room: 20 m² of suspended ceiling and 18 linear metres of perimeter lighting bulkhead.
Common mistake
Closing the ceiling before testing the services above, or without access panels at valves and AC units.
Frequently asked questions
How deep should the ceiling void be?
The services above set it; AC ducts need more depth than lighting alone.
Does a suspended ceiling need access panels?
Yes, at valves, AC units and junction boxes.
