Division 09 is the largest single scope in most building interiors, and it is the one most often split across four or five subcontractors. As a finishes estimating company, we take off the full package — gypsum board assemblies, acoustic ceiling tile and suspension grid, flooring, tile, wall covering, and coatings — so you can see the whole picture before you break it apart for bids. If you are pricing a drywall package alone, our Drywall Estimating & Takeoff page covers board, studs, finish levels, joint compound, and tape in detail. For flooring and paint as standalone scopes, see Flooring Estimating Services and Painting Estimating Services.

We work from the architectural sheets, reflected ceiling plans, finishes schedule, room finish schedule, door schedule, and window schedule, plus the specifications in the construction documents. Every line is tied to a CSI section number and a drawing reference, so your estimator can trace a quantity back to the sheet it came from. Board is measured by thickness and type, ceilings by grid and tile area, flooring by material and substrate — porcelain tile, stone flooring, vinyl plank, terrazzo, and carpet — and coatings by substrate and coat count, including stain and varnish on wood. Adjacent scopes that touch finishes — cold-formed framing in Division 05 metals, finish carpentry in Division 06 wood and plastics, concrete floor finishing in Division 03, masonry in Division 04, and joint sealants in Division 07 thermal and moisture protection — are flagged when they appear, so you can decide who carries them. If your project includes fire-rated assemblies, coordinate the tag lines with Fire Protection & Sprinkler Estimating and Fire Alarm & Low Voltage Estimating.
Turnaround is 24–48 hours for most projects, with rush available. Deliverables are Excel and PDF, organized by CSI MasterFormat division, with marked-up plan sets. Pricing is ZIP-code-adjusted for material and labor using RSMeans data, so the numbers reflect your market.

Drywall sheet calculator
Estimate board for a room or area. A full takeoff also separates board types, fire-rated assemblies, finish levels and framing.
Typical waste: 10–15%. Openings are usually not deducted when smaller than about 30 SF. Check the wall types and finish levels on the drawings.

How our finishes estimator performs a quantity takeoff
- Set up the finish scheduleWe extract every room finish tag from the architectural sheets and build a room-by-room matrix of floor, base, wall, and ceiling finishes. This becomes the control document for the takeoff. If the schedule and the plans disagree, we flag the conflict rather than pick one. For example, if a room is tagged with VCT but the plan shows LVT, we note both and ask for clarification. This step ensures that every finish is accounted for and that the takeoff aligns with the design intent.
- Take off board by assemblyEach wall type and ceiling assembly is measured separately. We read the UL or GA file number from the drawing, then apply the correct board type and thickness — 5/8 in. Type X on rated corridors and shafts, 1/2 in. regular on non-rated partitions, moisture-resistant at wet walls. Studs, plates, and blocking are taken off at the same time. For instance, a 1-hour rated corridor wall with 5/8 in. Type X on both sides requires 1-1/4 in. of board thickness, which affects the stud depth and the overall wall thickness. We also note any special conditions such as shaft walls or stairwells that may require additional layers or different board types.
- Measure ceilings from the RCPThe reflected ceiling plan gives grid layout, tile size, and edge detail. We measure the ceiling area, then take off main tee, cross tee, wall angle, and hanger wire separately. Tile waste at perimeter cuts is calculated from the room dimensions, not a flat percentage. For example, a room that is 12 ft 6 in. wide with 2x2 tile will have a 6 in. cut at one side, resulting in higher waste than a room that is an even multiple of 2 ft. We also note any special ceiling features such as soffits, clouds, or linear diffusers that may require additional grid or different tile.
- Measure flooring by substrateFlooring is measured room by room, with substrate noted — concrete slab on grade, elevated slab, or wood subfloor. Moisture testing and mitigation are listed as separate line items when the specification requires them. Transitions, reducers, and thresholds are taken off in LF. For instance, if the spec calls for a moisture barrier under LVT on slab on grade, we add a line for the membrane and note the required test method, such as ASTM F2170. We also note any floor prep required, such as patching or self-leveling underlayment, and measure it in SF.
- Apply coating systems by substratePaint is measured by substrate type — gypsum board, concrete masonry, exposed structure, or wood — and by sheen. The number of coats comes from the specification, not a default. Exterior coatings are measured with surface prep, primer type, and dry film thickness noted. For example, an exterior elastomeric coating over CMU may require a block filler and a primer, and the spec may call for a specific dry film thickness of 10 mils. We take off each coat separately and note the required surface preparation, such as power washing or sanding.
- Reconcile and mark upEvery line is checked against the finish schedule and the specification book. We mark up the plan sheets with color-coded highlights for each scope and deliver the Excel workbook organized by CSI section. Quantities are net; waste factors are shown as separate lines so you can adjust them. For instance, if the finish schedule calls for VCT in a room but the plan shows LVT, we flag the discrepancy and provide both quantities. We also cross-check the takeoff against the spec to ensure that all accessories, such as corner bead and control joints, are included.
What we need from you
- Architectural plansFloor plans, reflected ceiling plans, and interior elevations. We need the sheets that show room boundaries and wall types.
- Finish scheduleThe room-by-room schedule of floor, base, wall, and ceiling finishes. This is the primary control document for the takeoff.
- Specification bookDivision 09 sections with product requirements, coat counts, and installation standards. We read the spec, not just the drawings.
- Wall type detailsPartition types with stud size, spacing, and board thickness. If rated, the UL or GA assembly number.
- Bid date and scopeYour bid deadline and whether you want the full Division 09 package or a single sub-scope like drywall or flooring.
- Ceiling height and plenumFloor-to-floor and floor-to-ceiling heights, and whether the plenum is used as a return air plenum. This affects hanger wire length and grid type.

Units of measure we use
Finishes are measured in mixed units because the accessories do not scale with area. We keep board, trim, grid, and coating quantities on separate lines so nothing gets buried in a square-foot number.
| Item | Unit | How it's measured |
|---|---|---|
| Gypsum board | SF | Measured by wall and ceiling area, by thickness and type |
| Corner bead and trim | LF | Measured along exposed corners, edges, and control joint locations |
| Acoustical grid | SF | Measured as ceiling area; main tee and cross tee taken separately in LF |
| Resilient flooring | SF | Measured net room area plus waste; transitions and reducers in LF |
| Carpet | SY | Measured in square yards; seam layout and pattern match noted |
| Paint | SF | Measured by substrate and coat; sheen schedule applied |
| Sealant joints | LF | Measured at floor-wall, wall-ceiling, and expansion joints |
Worked example: takeoff of a small office suite
This example shows how we take off a small office suite with a mix of finishes. The dimensions are illustrative and are not a substitute for your actual plans. All quantities are net; waste is added as a separate step.
Room dimensions (illustrative):
- Office 1: 12 ft x 14 ft, 9 ft ceiling
- Office 2: 10 ft x 12 ft, 9 ft ceiling
- Corridor: 4 ft x 30 ft, 9 ft ceiling
- Restroom: 8 ft x 10 ft, 9 ft ceiling
Step 1: Gypsum board walls
- Office 1: perimeter = 2*(12+14) = 52 ft; wall area = 52 ft * 9 ft = 468 SF; deduct door 3 ft x 7 ft = 21 SF; net wall board = 447 SF.
- Office 2: perimeter = 2*(10+12) = 44 ft; wall area = 44 * 9 = 396 SF; deduct door 21 SF; net = 375 SF.
- Corridor: perimeter = 2*(4+30) = 68 ft; wall area = 68 * 9 = 612 SF; deduct two doors 42 SF; net = 570 SF.
- Restroom: perimeter = 2*(8+10) = 36 ft; wall area = 36 * 9 = 324 SF; deduct door 21 SF; net = 303 SF.
- Total wall board = 447 + 375 + 570 + 303 = 1,695 SF.
Step 2: Ceiling board
- Office 1: 12*14 = 168 SF
- Office 2: 10*12 = 120 SF
- Corridor: 4*30 = 120 SF
- Restroom: 8*10 = 80 SF
- Total ceiling board = 488 SF.
Step 3: Acoustical ceiling
- Corridor and restroom have suspended acoustical ceilings.
- Corridor: 120 SF; Restroom: 80 SF; total = 200 SF.
- Grid: main tee at 4 ft o.c. along corridor length: 30 ft / 4 = 8 runs * 4 ft = 32 LF; cross tee at 2 ft o.c.: 30 ft / 2 = 15 rows * 4 ft = 60 LF; wall angle: perimeter = 2*(4+30) = 68 LF.
Step 4: Flooring
- Office 1 and 2: carpet tile. Area = 168 + 120 = 288 SF. Convert to SY: 288 / 9 = 32 SY.
- Corridor: LVT. Area = 120 SF.
- Restroom: ceramic tile. Area = 80 SF.
Step 5: Paint
- Walls: 1,695 SF; Ceilings: 488 SF; total area = 2,183 SF. Primer + 2 coats.
- Door frames and doors: 4 doors * 2 sides * 21 SF = 168 SF.
- Total paint area = 2,351 SF.
Step 6: Waste factors (separate lines)
- Gypsum board: 10% waste = 1,695 * 0.10 = 170 SF (walls) + 488 * 0.10 = 49 SF (ceilings) = 219 SF.
- Acoustical tile: 5% waste = 200 * 0.05 = 10 SF; grid: 5% waste on 92 LF = 5 LF.
- Carpet tile: 10% waste = 32 SY * 0.10 = 3.2 SY.
- LVT: 10% waste = 120 SF * 0.10 = 12 SF.
- Ceramic tile: 15% waste = 80 SF * 0.15 = 12 SF.
- Paint: no waste factor; material coverage calculated from spread rate.
Step 7: Accessories
- Corner bead: count exterior corners: Office 1: 4 corners * 9 ft = 36 LF; Office 2: 4 * 9 = 36 LF; Corridor: 2 * 9 = 18 LF; Restroom: 4 * 9 = 36 LF; total = 126 LF.
- Control joints: at 30 ft o.c. in corridor: 30 ft / 30 = 1 joint * 9 ft = 9 LF.
- Base: rubber base in offices and corridor: perimeter of offices and corridor minus doors: Office 1: 52 - 3 = 49 LF; Office 2: 44 - 3 = 41 LF; Corridor: 68 - 6 = 62 LF; total = 152 LF.
- Sealant joints: at floor-wall in restroom: 36 LF.
This is the level of detail you get in the Excel workbook. Each line is tied to a drawing reference and a CSI section.
What moves the finishes cost estimating number
Relative impact on a typical estimate for this trade, based on estimator judgment. Select a bar for details.
Board type
5/8 in. Type X costs more than 1/2 in. regular, and the difference is not linear across the project. Rated corridors, shafts, and stairwells drive the quantity. If the drawings show a rated assembly but the schedule calls out regular board, we flag it before pricing.
5/8 in. Type X costs more than 1/2 in. regular, and the difference is not linear across the project. Rated corridors, shafts, and stairwells drive the quantity. If the drawings show a rated assembly but the schedule calls out regular board, we flag it before pricing.
Level 4 and Level 5 gypsum board finishes require more skim coat and sanding labor than Level 3. The finish schedule may specify Level 5 in lobbies and corridors while the bid is based on Level 3. We take off the level shown and note the difference.
A 15/16 in. exposed tee grid with 2x2 lay-in tile is the baseline. Concealed grid, tegular edge, and specialty ceilings change both material and labor. Seismic zones may require perimeter clips and sway bracing, which are separate line items.
Resilient flooring over a concrete slab on grade needs moisture testing and possibly mitigation. Over an elevated slab, the prep is different. Epoxy coatings require surface profile and may need a primer. The substrate drives the prep line, which is often the largest variable.
Interior paint is usually a primer plus two finish coats. Exterior elastomeric coatings may require a block filler and a specific dry film thickness. The number of coats and the surface prep are specified, not assumed. VOC restrictions in some jurisdictions limit product selection.
Tall walls and complex room shapes increase board and scaffolding labor. A 20 ft high wall in a stairwell requires scaffolding and may need a different board orientation. We measure wall area by height and note any special access requirements.
High NRC ceilings and sound isolation assemblies require specific tile and board types. A sound transmission class (STC) rating may call for resilient channels or double-layer board. These assemblies cost more and are taken off separately.
Common scope gaps we catch
Finishes scopes overlap with framing, concrete, and sealants. These are the lines that get dropped when the package is split across subcontractors.
- Board type substitutions: the drawings show a 1-hr rated assembly requiring 5/8 in. Type X or C, but the bid uses 1/2 in. regular. We read the UL or GA tag and take off the board the assembly requires.
- Corner bead, control joints, expansion joints, and J-trim are measured in LF, not SF. They are often left out of a square-foot bid. We take them off separately and show them on their own lines.
- Acoustical tile waste at perimeter cuts depends on room dimensions. A flat 5% waste factor underestimates a room with a 2 ft 6 in. wide perimeter cut. We calculate waste from the actual layout.
- Floor moisture testing and mitigation are required before resilient or epoxy flooring. The specification may call for it, but it is not a flooring line item. We list it as a separate prep line.
- Carpet seam layout, pattern match, and attic stock are specified in Division 09 but often bid as plain square yards. We note the seam diagram and attic stock quantity when shown.
- Paint sheen schedule and number of coats vary by room. A single square-foot price for all interior paint ignores the difference between eggshell in offices and semi-gloss in restrooms. We take off by sheen.
- Access panels, transitions, reducers, and thresholds are small LF and EA items that disappear in a lump sum. We list them by type and location.
- Blocking for wall-mounted items: toilet partitions, grab bars, and wall guards require blocking in the wall. This is often missed in the drywall scope and becomes a change order. We note blocking locations from the architectural plans.
- Fire-rated joint systems at floor and wall penetrations: Division 09 may include firestop sealants and systems, but they are sometimes left to Division 07. We flag these joints and list them separately.
Material and system pricing drivers
Each finish system has a primary cost driver. This table shows the axis we use when we compare systems and price them.
| System | Primary driver | Secondary driver | Unit |
|---|---|---|---|
| Gypsum board | Board type (Type X, MR, regular) | Finish level (3, 4, 5) | SF |
| Acoustical ceiling | Grid exposure and tile edge | Seismic category | SF |
| Resilient flooring | Substrate prep and moisture mitigation | Wear layer thickness | SF |
| Carpet | Face weight and backing | Pattern match and seam layout | SY |
| Interior paint | Sheen and number of coats | Substrate porosity | SF |
| Exterior coating | Surface prep and DFT | VOC restrictions | SF |
| Tile | Tile size and material | Substrate and waterproofing | SF |
Codes and standards that affect the takeoff
Model codes
Finishes are governed by the adopted building code, typically the IBC or IRC. The IBC sets flame spread and smoke-developed limits for interior wall and ceiling finishes (Chapter 8), which determines whether you need Class A, B, or C materials. It also regulates fire-rated assemblies (Chapter 7) and requires specific board types and thicknesses. The IECC addresses insulation and air sealing, which can affect exterior wall finishes. Confirm the adopted edition with your local building department, as editions vary by state and jurisdiction.
Industry standards
Gypsum board assemblies follow GA-216 (application) and GA-214 (finish levels). ASTM C840 covers installation, and ASTM C754 covers steel framing. Acoustical ceilings reference ASTM C635 and C636. Flooring standards include ASTM F1700 (solid vinyl), ASTM F3261 (resilient floor tile), and ASTM F2170 for moisture testing. Paint standards include ASTM D523 for gloss and ASTM D4414 for DFT. These standards define what the spec requires and how we take it off.
Specification sections
Division 09 sections are the core: 09 20 00 (gypsum board), 09 51 13 (acoustical ceilings), 09 65 00 (resilient flooring), 09 68 00 (carpet), 09 90 00 (paints and coatings). Also read 09 30 00 (tiling) and 09 96 00 (high-performance coatings). Each section specifies products, installation methods, and quality standards. The finish level, coat count, and substrate prep are cost drivers. Cross-reference with Division 05 (cold-formed framing), Division 06 (finish carpentry), Division 03 (concrete floor finishing), and Division 07 (joint sealants).
Local amendments
Local jurisdictions may amend the model codes. For example, some areas require stricter VOC limits for coatings or additional seismic bracing for ceilings. Fire-rated assembly requirements may be modified based on local fire codes. Always confirm the adopted code edition and any amendments with the local building department. The takeoff must reflect the code that is enforced in the project location, not just the model code.
