Definition
A reflected ceiling plan draws the ceiling as if mirrored on the floor, showing suspended ceiling types and levels, cornice details, and positions of lights, AC diffusers, smoke detectors and access panels.
Why it matters on a project
It is where interior design meets MEP. Without it, or without coordination, electricians and HVAC trades place outlets where they like and the ceiling design is lost.
Measurement and pricing
Ceilings in square metres per type, cornices and shadow gaps in linear metres, lights and outlets by number.
Common mistake
Approving the ceiling plan after ducts and conduits are installed, so levels clash with beams and ductwork.
Frequently asked questions
Why is it called reflected?
Because the ceiling is drawn as if mirrored on the floor, so it keeps the same orientation as the floor plan.
Who prepares the ceiling plan?
The interior designer or architect, coordinated with the electrical and HVAC designers.
