Units of measure for flooring
Each piece of flooring work has its own unit, and keeping them apart is what makes the estimate checkable. These are the units estimators use and how each is measured.
| Item | Unit | How it's measured |
|---|---|---|
| Resilient, tile, carpet tile | SF | Room area by material from the finish schedule. |
| Broadloom carpet | SY | Area ÷ 9, laid out on roll widths to account for seams. |
| Cartons or boxes | each | SF with waste ÷ SF per carton, rounded up. |
| Base | LF | Room perimeter less door openings. |
| Transitions | each or LF | At every change of material and at doorways. |
| Underlayment and prep | SF | Where specified; tool adds 5% to underlayment. |
How estimators take off flooring
- Group rooms by finish. Use the finish plan or schedule to tag each room with its flooring, base and any special prep.
- Measure net area. Room length × width, with casework and fixed equipment deducted if flooring doesn't run under them.
- Apply waste by material and layout. The takeoff tool's defaults: 5% for carpet tile, 7% for LVT plank and 12% for porcelain tile. Diagonal layouts and small rooms need more.
- Round to cartons. Order quantities round up to full cartons, and attic stock is added if the spec calls for it.
- Add base, transitions and prep. Count transitions at every material change and measure base by perimeter. Price floor prep and moisture testing as separate lines.
Waste factors and order quantities
Waste covers cut-offs, breakage, laps and spillage, and it's added to the net quantity before rounding up to what the supplier sells. Figures marked as tool defaults are the same ones the Trade Takeoff Worksheets start with, and you can edit them there.
| Item | Factor | Notes |
|---|---|---|
| Carpet tile | 5% | Tool default in the sample takeoff, square rooms. |
| LVT plank | 7% | Tool default in the sample takeoff. |
| Porcelain tile | 12% | Tool default; 10 to 15% for tile or diagonal layouts. |
Crew production rates
Labor is quantity divided by production. These rates are per 8-hour crew-day for commercial work, from the same library as the crew-day production estimator: typical mid-range planning values with a low-to-high range, not a promise of output. Crew skill, layout, access and weather move them, and your own crews' records beat any library.
| Activity | Crew | Low | Typical | High | Labor |
|---|---|---|---|---|---|
| Luxury vinyl tile | 2 installers | 600 | 800 SF | 1,000 | 2.0 hrs per 100 SF |
| Carpet tile | 2 installers | 1,000 | 1,300 SF | 1,600 | 1.2 hrs per 100 SF |
- Luxury vinyl tile 600 to 1,000 SF, typical 800
- Carpet tile 1,000 to 1,600 SF, typical 1,300
Worked example: 9,000 SF of luxury vinyl tile
The activity is luxury vinyl tile, with a crew of 2 installers at the typical rate of 800 SF per crew-day:
- Crew-days: 9,000 SF ÷ 800 = 11.3 crew-days.
- Labor hours: 11.3 crew-days × 2 workers × 8 hours = 180 hours.
- Range: 9 crew-days at the high rate to 15 at the low rate, a spread of 6 crew-days on the same quantity.
Multiply the labor hours by your burdened hourly cost to price the labor. The spread between the low and high rate is why production is the assumption to check first on a flooring bid: the same takeoff can carry very different labor. Run your own quantities in the crew-day production estimator, and get the burdened rate from the labor burden calculator.
What drives the cost
- Floor preparation. Patching, leveling and moisture mitigation can cost more than the flooring on a bad slab.
- Pattern and layout. Diagonals, borders and mixed patterns raise both waste and labor.
- Room size. Small rooms and corridors have more cuts and transitions per SF than open areas.
- Occupied or phased work. Moving furniture and working in phases cut production.
Common exclusions and clarifications
A flooring price is only as good as the scope it describes. These exclusions come from our scope library for flooring (CSI 09 60 00); list the ones that apply so the GC levels your number fairly.
- Moisture testing and moisture mitigation systems.
- Floor leveling beyond standard preparation.
- Removal of existing flooring and adhesive unless listed as included.
- Moving furniture and equipment.
- Attic stock beyond the quantity specified.
Clarifications that often go with them:
- Standard preparation up to 1/8 inch of patching included; leveling beyond that is extra.
- Moisture testing and mitigation by others unless listed.
