Studs, trim, and casework — board-fed to the nearest hour.
Pilrs reads framing plans, wall sections, and finish schedules to count studs, plates, headers, and rim joists for rough carpentry, plus doors, trim, and casework for finish carpentry — all with board-foot yields and stick counts.
Carpentry covers two radically different scopes — rough framing priced by stud count and board feet, and finish carpentry priced by linear feet, door count, and hardware groups. A mid-size commercial tenant improvement might have 8,000 LF of wall framing (28,000 studs), 400 doors, 12,000 LF of base trim, 200 LF of casework, and 60 windows — each scope with its own takeoff discipline, waste factor, and labor productivity.
The takeoff bottleneck is opening accounting. A 100-foot wall at 16" o.c. has 76 studs from a flat formula, but every door adds king studs (2), trimmers (2), header (1-3 plies of 2x10 or LVL), and cripples above and below. A wall with 8 openings adds 80-120 sticks beyond the field studs. Manual estimators apply "wall LF × studs per foot" and miss 12-18% of stick count on opening-dense walls — every miss is $4-8 of material and 0.15 labor hours.
Door and hardware reconciliation is the finish-carpentry killer. A commercial door schedule lists HW-1 through HW-14, each with a unique component list (3 hinges, lockset, closer, kick plate, silencers, threshold, weatherstripping). Missing one hardware component on 200 doors is $200-680 per door of unbid material plus the field labor to retrofit. Estimators tracking hardware groups by hand miss 15-25% of components on multi-group projects.
A 100 LF wall at 16" o.c. has 76 field studs — but a wall with 6 doors and 2 windows adds 16 king studs, 16 trimmers, 8 headers (each 1-3 plies), and 24-32 cripples. That single wall has 140-160 sticks total, not 76. Manual estimators using wall LF × density miss 60-80 sticks per opening-dense wall.
A header callout of "(3) 1-3/4 x 11-7/8 LVL" at 4,500 plf design load means 3-ply LVL at $14-18/LF per ply. Substituting 2-ply at the same depth fails the load check. Manual estimators reading the header schedule but not verifying ply count under-purchase $4-8 per LF on every header — a $2,000-4,000 miss on a typical commercial project.
A door casing is 17 LF per opening (head + 2 jambs + 1 LF transition); on 80 doors, that is 1,360 LF plus 12-15% waste = 1,560 LF needed. Window trim adds another 800-1,200 LF. Base trim runs 95-105% of room perimeter LF after door deductions. Estimators applying flat wall-LF × 2 multipliers miss the per-opening trim component and the waste compounding.
Base cabinets at $145-280/LF, upper cabinets at $95-180/LF, tall cabinets at $220-380/LF. Specialty cabinets (sink base, drawer base, blind corner) cost 25-40% more than standard. Countertops at $42-180/SF depending on material. Manual takeoffs lump casework as "linear feet of cabinet" and miss the size and specialty premiums by 15-25%.
HW-3 might be: 3 ball bearing hinges (BB1199 4.5x4.5), Sargent 8200 mortise lockset, Norton 8501 closer, kick plate (10x34 stainless), wall stop (FB13), 3 silencers, weather stripping (perimeter set). Each item has an SKU, vendor, and lead time. A 200-door project with 6 HW groups has 1,200+ component lines. Manual estimators miss 15-25% of components on first pass.
IBC and IRC nailing schedules for shear walls vary by wind/seismic zone — perimeter nailing at 4" o.c., field at 6" or 8" o.c. depending on shear capacity required. Hurricane zones and seismic D2 zones require 3" perimeter spacing. Manual takeoffs apply standard 6/12 nailing pattern and undercount fastener requirements by 35-50% in high-seismic or hurricane areas.
The line items that slip between plan sheets — and the dollars that leave with them.
Grab bars, cabinets, handrails, TV mounts, and partition wing walls all need 2x blocking. A typical commercial project has 2,000-4,000 LF of blocking at $1.40/LF — frequently a $3,000-6,000 miss in bid scope.
Fire blocking required at floor lines, ceiling lines, soffits, and chases. On a 4-story building, 800-1,200 LF of fire blocking at $2.20/LF is $1,800-2,600 of often-missed code requirement.
Hollow metal frames typically arrive shop-primed but need field paint to match spec. Painting scope coordination at $14/frame for 200 frames is $2,800 — sometimes split-bid wrong between trades.
Cores, keys, and master keying systems run $40-120 per door beyond the lockset. On 200 doors, that is $8,000-24,000 of often-missed scope.
IBC 2024 fire-blocking and energy code requirements are tightening framing scope on every commercial project. Continued lumber and engineered wood pricing volatility plus the 32% commercial carpenter shortage make speed and accuracy in takeoff critical. Pilrs cuts a 7-hour TI carpentry takeoff to 90 minutes and lets contractors bid 4-5x more work per estimator.
Rough carpentry takeoffs fail on stud math. A 100-foot wall at 16" on center has 76 studs (100 feet times 0.75 per foot, plus one for the starter and doubles at corners), plus a continuous double top plate and single bottom plate, plus extra studs at every opening. The stud count scales with framing complexity, not wall length alone. A spreadsheet that applies a flat "studs per foot" multiplier is always wrong by a predictable amount, which is better than random but still not good.
Openings are the second killer. A typical exterior wall has a door every 40 feet and a window every 15 feet. Each opening adds a header (two 2x10s with a 1/2" plywood spacer for a 2x4 wall), a king stud each side, a trimmer each side, and cripple studs above and below the opening at the same spacing as the field studs. Over 30 openings, that is 90 to 150 extra sticks unaccounted for in a simple "linear feet of wall times studs per foot" model.
Finish carpentry fails on scope boundaries. A door schedule lists the door, frame, and hardware group. A commercial door might include: door leaf (solid core HP), frame (HM 16-gauge), three butts, lockset (Schlage L9050 or equal), closer (LCN 1461), kick plate, silencers, weatherstripping, and thresholds. Pricing the door alone and forgetting the hardware is a $150 to $400 miss per door. On a 200-door TI, that is real money.
Pilrs reads framing plans and wall sections for rough carpentry — counting studs, plates, headers, trimmers, cripples, blocking, and sheathing. For finish carpentry, it reads the door schedule, finish schedule, casework schedule, and millwork drawings to quantify doors with hardware groups, trim by LF with substrate (MDF, poplar, pine, hardwood), and casework by LF of cabinet run with tops, splashes, and fillers.
Studs per wall calculated at spec spacing with double-top-plate, bottom plate, corners, and blocking included.
Every door and window opening adds header, king studs, trimmers, and cripples — counted automatically from the opening schedule.
Beams, headers, and rim joists in LVL, PSL, or glulam quantified per spec with embed and connector counts.
Each door tagged with leaf type, frame type, and hardware group from the schedule. Hardware groups expanded into their component items.
