RCPs are difficult due to the separate trades doing design work - architectural,
mechanical, electrical and plumbing (sprinklers). So what is documented depends
largely on the makeup of the project team and your particular discipline.
Regardless of what YOU do, it requires a lot of coordination between the trades,
which is often why ceiling plans are the ones most susceptible to problems
during design and construction.
From an Architect's standpoint, at a minimum, an RCP shows the ceiling finishes
(suspended grid with start points, gyp. bd. soffits w/dimensions) and a complete
lighting layout, including all wall sconces and decorative lighting. Along with
that we also document the specifications for lighting fixtures, specialty
fixtures (speakers) and any decorative ceiling elements, such as Axiom trim.
Often in renovation work there is something that needs to be done to indicate
existing/relocated fixtures.
Equally important is to indicate emergency lighting location and function, which
is required to get a permit.
The design for interior lighting and layout is under the purview of the
architects. Engineers must deal with the electrical requirements, but lighting
is a high design area. Often it is dictated by other architectural elements such
as furniture layout, and directly tied into other areas such as LEED ("Green"
building) certification
Often we will draw switching, particularly for complex layouts with multiple 3-
or 4-way switches, but sometimes we do not and just indicate special things in
notes if it's a design build type situation.
With MEP folks, they add their HVAC return/supply grilles and sprinkler heads,
along with other Life Safety equipment (C02 detectors). You may have security
consultants add their own things, like motion detectors or specialty ceiling
panels.
These other disciplines may document this on their drawings (using the
architectural RCP as a background), or submit their RCPs back to the Architect
to be composed into a single complete Ceiling Coordination Plan.
