What we count on an
ACT takeoff

Tile, grid, trim, suspension and every edge condition — because on a ceiling package the perimeter is where the labour lives, not the field. A room with twice the perimeter and the same area is a different job, and the workbook shows it that way.

  • Ceiling areas by ceiling type and tile specSF / m²By tile size, edge detail (square lay-in, tegular, concealed), NRC and CAC class, and finish — each ceiling code its own line, by room and level.
  • Suspension grid by profileLF / mMain tees, cross tees and the face width the spec calls for — 15/16", 9/16" narrow, slotted — counted separately.
  • Perimeter trim by conditionLF / mWall angle, shadow moulding, channel and trim at bulkheads, soffits, columns and glazing heads — by the condition, not by room perimeter alone.
  • Hanger wire and suspension pointsEAFrom the grid layout and the ceiling height, with long drops flagged.
  • Seismic bracing and compression strutsEAWhere the structural and ceiling details call for them.
  • Ceiling height changes and level transitionsLF / EA
  • Clouds, floating panels and open-cell ceilingsSF + LF perimeterArea and the full edge run, which is usually where the cost sits.
  • Linear, baffle and specialty ceilingsSF / LF

METHODHow we measure itBasis stated in writing

How we measure
acoustic ceilings

Everything comes off the reflected ceiling plans, tied to the ceiling type legend and checked against the sections for height. Field area is the easy part — what we spend the time on is the perimeter, the height changes and the interfaces, which is where a ceiling package is won or lost.

RCP FIRST

The reflected ceiling plan is the drawing that matters

Ceiling types come off the legend with tile size, edge detail, grid profile and acoustic ratings recorded for each. Areas are then measured room by room against that list, with the ceiling height noted, so a 2700 mm ceiling and a 4000 mm ceiling of identical area never share a line.

PERIMETER

Edge conditions are counted by condition, not by room

Wall angle against gypsum, shadow moulding at a feature edge, trim at a bulkhead and trim at a glazing head are four different details and four different rates. We measure each run by the condition it meets, which is why the perimeter often has more lines than the field does.

GRID

Grid is measured as grid, not derived from area

Main tee and cross tee quantities depend on the module and the direction the grid runs, and a room's shape changes both. We take the grid off the layout rather than multiplying area by a rule of thumb, and mains, crosses and trim are reported separately.

SUSPENSION

Hangers follow the height, and long drops get flagged

Hanger counts come from the grid layout and the structure above. Where the deck is high — open ceilings, atriums, back-of-house over exposed structure — the drops are long enough to change the install rate, and those areas are separated so you can price them honestly.

INTERFACE

The bulkhead line is named, not assumed

Where a ceiling dies into a drywall bulkhead, the framing can fall to either trade depending on the spec. We quantify the interface in lineal feet and name which division the spec puts it in — the same condition we flag from the other side on drywall takeoffs.

SEISMIC

Bracing is read out of the details, not guessed

Ceiling bracing and compression strut requirements come from the ceiling details and the structural notes. They're quantified as counts against the areas they apply to, rather than carried as a lump allowance you can't defend in a scope meeting.

REPETITION

Typical floors are measured once and extended, visibly

A typical floor is measured in full and extended across the levels it applies to. The workbook shows which levels were measured and which were extended, and any level that differs is measured on its own. You can audit the multiplier.

UNITS

Metric or imperial, whichever you bid in

Commercial and institutional sets in Canada are commonly metric; residential work is often imperial. The workbook arrives in the units you price with, or both columns, with the ceiling type codes carried through exactly as the legend writes them.

GAPSScope gaps we flagCaught before you bid

Scope gaps we flag
on ceiling packages

The six that cost ceiling subs money most often. Each one lands on the assumptions and exclusions page with the sheet it came from, so you can qualify it in your bid instead of meeting it in a change order.

DIVISION LINE

Who frames the bulkhead the ceiling dies into

It reads as one continuous surface on the RCP and it is two trades on site. Depending on how the spec is written, the bulkhead framing is yours or the drywall sub's. Both of you assuming the other has it is the single most common gap on an interiors job.

PERIMETER

Trim priced off room perimeter

Perimeter length and trim length aren't the same number. Columns, returns, bulkhead faces, soffits and glazing heads all add edge that a room outline doesn't show. On a plan with lots of small rooms, that difference is most of the labour.

SEISMIC

Bracing carried as an allowance

Bracing and compression struts are detailed requirements with real counts attached. Carried as a lump-sum allowance they're either padding you didn't need or a shortfall you can't recover, and neither reads well in a scope review.

HEIGHT

Long drops averaged into the field rate

A ceiling hung two metres below a high deck installs nothing like one tight to the structure. Averaged in with the standard field area, the extra suspension, the access and the time all vanish from your number.

SPEC

Attic stock buried in the specification

Extra tile percentages sit in the Division 09 spec, not on any drawing. It's real material, ordered at the start and delivered at the end, and it's easy to leave out of a bid built only from the plans.

RATED ASSEMBLIES

Rated ceilings counted as standard ACT

A fire-rated ceiling membrane carries different tile, different clips and hold-down requirements, and different inspection. Same square footage on the RCP, different assembly — so it gets its own line with the rating attached.

More of these by trade in the bid traps list, and the cost side in what a construction takeoff costs in Canada.

FAQACT takeoff questions

Acoustic ceiling takeoff FAQs

How much does an acoustic ceiling takeoff cost?
From $450 — the same tier as the other single-trade finish takeoffs. What moves the fixed price is sheet count, how many ceiling types are in the legend, how many levels there are, and how much of the set genuinely repeats. A written fixed quote comes back within 4 business hours and doesn't move afterwards. Full schedule on the takeoff pricing page.
How fast is it delivered?
Next business day on single-trade ceiling sets. Larger or multi-building sets get a firm delivery date with the quote. Same-day rush is +50%. If it lands after the date on the quote, you pay half.
Do you count grid separately from tile?
Yes. Tile goes in by area and ceiling type; mains, cross tees and perimeter trim go in by lineal foot and profile. Grid quantities depend on the module and the direction it runs, so they're taken off the layout rather than derived from area with a multiplier.
Do you handle the bulkhead interface with the drywall sub?
We quantify it and name it. Every run where a ceiling meets a drywall bulkhead or soffit is measured in lineal feet, and the assumptions page says which division the spec puts the framing in. That way you price it or exclude it deliberately, and the same condition is flagged from the other side on the drywall takeoff.
Are light fixtures and diffusers counted?
They're counted as cut-outs and integration points from the reflected ceiling plans. The fixtures and diffusers themselves are mechanical and electrical scope, which SharpBid does not take off, but the cuts and the coordination they create in your grid are yours and they're quantified.
Can the workbook use our own cost codes?
Yes. CSI MasterFormat is the default; send your cost code list and the workbook is built to it, so quantities drop into your estimating system without re-mapping.
What's excluded?
Pricing, unless you add price placeholders. Mechanical and electrical entirely — SharpBid doesn't take off Divisions 21 through 28. Anything the drawings genuinely leave undetermined is listed on the assumptions page instead of buried in a quantity.
