No single product on the interior finishes list is the risk. The risk is that a section reading like one continuous scope is actually a dozen separate assignment questions stacked on top of each other, and the split changes from item to item inside the same schedule.
Item by item
- Suspended acoustical ceilings. Grid and tile per the reflected ceiling plan and finish schedule, trim, transitions, seismic requirements where specified. Reliably yours, no split to chase.
- Architectural millwork and casework. Installation of shop-fabricated millwork, running trim, standing-and-running woodwork — yours. But check the supply-versus-install split per item, not once for the whole schedule; it changes line to line. When the documents split supply from install outright, shop fabrication and finishing belong to the fabricator, and your obligation starts at delivery.
- Wall coverings and special wall surfacing. Vinyl and textile wallcoverings, acoustic panels, specialty surfacing per the finish schedule. Yours, straightforward.
- Interior specialties. Toilet partitions and accessories, wall and corner protection, lockers, signage — the Division 10 items the tender actually assigns here. Not automatic: confirm rather than assume every Division 10 item lands with this trade by default.
- Entrance mats and grilles. Recessed mats, frames, foot grilles. The recess itself is concrete's to form; pricing the frame without confirming who built the pocket it sits in is a classic miss.
- Demountable and operable partitions. Often their own supplier-installed system entirely, priced and scheduled separately from the standard install labour covering the rest of the section. Don't fold it into the wallcovering or millwork line just because it sits in the same part of the spec — a supplier-direct system with its own commissioning requirements is a different bid altogether.
- Ceiling clouds and specialty ceilings. Wood, metal, felt and baffle systems are premium products with genuinely long lead times. Price and order them as their own line items, not folded into a standard acoustical allowance — missing the lead time here is a schedule problem before it's a cost problem.
- Interior protection. Temporary protection of finished floors, walls and vertical transportation, where the documents carry it as its own scope: materials, duration, who maintains and removes it.
What belongs to the trade next door
- Gypsum board assemblies and framing — drywall's. This scope finishes surfaces drywall already built; it doesn't build the wall, even where the two trades' work sits inches apart.
- Flooring and painting — separate schedules, separate sequencing. Where this scope depends on when flooring or paint runs, and it usually does, confirm the dependency rather than assume a typical sequence.
Five things the RCP and finish schedule don't mention
- Seismic and engineering requirements for ceilings. Categories, perimeter bracing, compression posts — real engineering cost, usually stated once in a general note rather than repeated on every ceiling detail.
- Ceiling plenum congestion. Overlay the RCP against the mechanical drawings, not just read it alone — that's what reveals a tight plenum that slows grid installation and forces sequence changes.
- Backing and blocking. Accessories, partitions and wall protection all need backing, and the documents put that duty in an inconsistent place. Usually drywall's wall, but when it's missing at rough-in, solving it becomes this trade's problem, on schedule.
- Attic stock and spare tiles. Percentage requirements stated one line deep inside each individual section, which is exactly why they're easy to price at zero by accident.
- Owner-supplied items. OFCI accessories and equipment this trade installs need their supply-versus-install language checked per item, not assumed from whichever one you read first.
Who you're sharing the ceiling with
| Trade | What to reconcile before you price |
|---|---|
| Mechanical & electrical trades | Fixtures, diffusers and sprinklers in the grid — layout ownership, cutting, and who moves what when the RCP and services collide. |
| Drywall trade | Bulkhead and soffit interfaces with the grid, plus backing inside walls for this trade's mounted items. |
| Flooring trade | Sequence at millwork and partitions — what installs first decides scribe and base conditions. |
| General contractor | Conditioned space and dust control before ceilings and wallcoverings go in, plus attic stock handover at closeout. |
The one pass worth repeating
Read the finish schedule and reflected ceiling plan together once, for the product list. Then go back through it a second time, hunting only for supply-versus-install language on demountable partitions, specialty ceilings and entrance mats. The first pass tells you what to install. The second is the one that keeps this from turning into a closeout argument.
