Wall panel takeoff software.

What wall panel takeoff software needs to do

I have priced all three kinds of wall panel work, and the trap is treating them as one trade because the word is the same. A panelized wall plant estimates lumber or light-gauge steel per panel. A metal panel sub estimates a rainscreen by the square foot with a long list of accessories. An interior contractor counts acoustic or FRP panels by the piece against a finish schedule. Different drawings, different spec sections, different units, so this page takes them one at a time.

Prefab framed wall panels: panelized wall takeoff

Panelized wall takeoff starts with linear feet of wall by wall type and plate height. Pull the wall types from the plan legend and the framing plans, separate exterior from interior and bearing from non-bearing, and measure each run at its actual plate height. A 9 ft plate on the first floor and an 8 ft plate on the second are different panels with different stud lengths.

Then break the wall into panels. If the set includes a panel schedule or layout, count panels directly and check total length against your wall measurements; if not, set the breaks yourself at corners, openings and maximum shipping length. Each panel then gets its own material list: studs at the specified spacing plus extras at ends, corners, intersections and each side of every opening; top and bottom plates; headers by opening width from the header schedule; cripples, sills and jack studs per opening; sheathing by panel face area; and the hardware the structural drawings call out, holdowns and straps on wood, clips, bridging and screws on light-gauge steel.

Deduct the rough opening area from sheathing, but not from stud count, because a window adds studs rather than removing them. Corners and intersections add plates and studs that a linear-feet-times-studs-per-foot calculation never sees. Read 06 12 00 for structural wood panels and 05 40 00 for cold-formed metal framing, and check the structural general notes, which usually override both on fastener schedules. See framing takeoff software and how AI automates framing takeoff for the wider framing scope.

Exterior architectural panels: ACM, insulated metal, precast, fiber cement

Exterior panel takeoff is an elevation exercise. Plan views compress the facade, so measure net wall area from every elevation by panel type and finish, subtract openings above whatever threshold the spec or your fabricator uses, then add everything that lives around the panels, which on a rainscreen system is where the money hides.

Metal composite material (ACM) and plate panels. Net square feet by finish, then panel count if the elevations show a layout or the spec calls for a panel schedule. Behind them: linear feet of sub-girts or hat channels at the specified spacing, clips, extrusions at every joint, and flashings and closures at every edge, corner, parapet, window head and sill. Corners and returns are counted separately because they are fabricated pieces priced each or by the foot, not folded into field area.

Insulated metal panels (IMP). Square feet by thickness and profile, panel count by length where the layout is fixed, then trims, clips, fasteners and sealant per joint. IMPs are often laid horizontally, so joint count comes from panel width and wall height, which area alone never tells you.

Precast and tilt-up concrete panels. Count each panel from the panel elevations and schedule, with per-panel square feet, thickness, finish, and the embeds, connections and lifting inserts the structural drawings call out. Tilt-up adds casting bed and bracing.

Fiber cement and similar sidings. Net square feet by product, trim by linear foot at corners, openings and transitions, plus starter strips, furring where a rainscreen gap is specified, and fasteners by exposure.

Spec sections: 07 42 00 for wall panels, with metal, composite and insulated panels in their own subsections, 03 45 00 for precast, 03 47 00 for tilt-up, and 07 46 00 for siding. Read the spec for waste allowance and minimum order per finish color.

Interior wall panel systems: acoustic, FRP, demountable

Interior panels are a finishes takeoff, and the finish schedule carries the scope. Acoustic wall panels: count pieces by size and fabric from the finish schedule and interior elevations, carry square feet as a check, add clips or Z-bar per panel. FRP in kitchens, restrooms and wash-down areas: net square feet per room at the scheduled height, sheets against the specified sheet size, moldings and divider bars by the linear foot, adhesive and rivets per sheet. Demountable partitions: modules by type and height from the partition plans, then doors, glazed modules, corner posts and end conditions each as a piece.

The spec references live in Division 09. Interior panel work is where the finish schedule and the interior elevations disagree most often, so reconcile them before you count. Our drywall takeoff software page covers the substrate side of the same walls.

Panel types, what you count, and the unit

The mistakes that cost money on a wall panel takeoff

• Measuring exterior panels from the plan instead of the elevations. Plan length times an assumed height misses parapets, stepped roofs, and any facade that is not a flat rectangle.
• Carrying area only on a system priced by the piece. Corners, returns, column covers and soffit transitions are fabricated pieces. Ten feet of outside corner is not ten square feet of field panel.
• Deducting openings the wrong way. Deduct opening area from sheathing and cladding, but openings add framing, trim, flashing and sealant. A wall with twenty windows has more framing than a blank wall of the same length.
• Forgetting the layer behind the panel. Sub-girts, hat channels, clips, air barrier tie-ins and insulation are often in the panel sub's scope and always missing from an area-only number.
• Using one waste factor for everything. Field panels on a simple elevation might waste five percent; a facade with many finishes and short panels wastes far more, and minimum order per color can matter more than the waste line.
• Picking a side when the schedule and the elevations disagree. That is an RFI, not a coin flip. Note the conflict and price the more expensive reading until it is resolved.

How Pilars automates wall panel takeoff

Pilars reads the whole set rather than one sheet at a time, which is what wall panel work needs. Upload the plans and the spec book, and it reads the elevations for net facade area by panel type, the wall type legend and framing plans for linear feet of wall by type and height, the panel, header and finish schedules with each entry tied back to its sheet, and spec sections 05 40 00, 06 12 00, 07 42 00 and the Division 09 finish sections for the accessories, waste allowances and fastening requirements that never show up on a drawing.

The output is a takeoff summary and an Excel or BOQ export: linear feet of wall by type, panel counts, net square feet by finish, openings deducted with the framing and trim they add carried separately, corners and returns on their own lines, and girts, clips and fasteners per the spec. Every quantity is confidence-scored and sourced to the sheet, so review means checking flagged items rather than re-measuring the facade. Manual: 40 to 80 hours. Pilars: minutes plus your review.

It runs in the browser on any machine at $100 per trade per plan set, unlimited projects and users. The fastest way to judge it is to run it on your own set; how AI takeoff works explains the pipeline first if you prefer.
