A pre-engineered metal building is a hybrid scope: the manufacturer furnishes primary and secondary framing, cladding, and trim, while the metal building foundation, erection, insulation, doors, and finishes are bid separately. If you send us the PEMB drawings, erection drawings, and foundation plans, we take off the entire anchor-bolt-to-ridge package so nothing falls between the dealer quote and your bid. That package is what most contractors mean when they ask for a metal building takeoff, and it is the only way to compare a dealer quote against your own numbers line by line.

We organize the takeoff by CSI MasterFormat division, starting with Division 03 concrete for slab on grade and pier footing work, then Division 05 metal building systems, Division 07 thermal and moisture protection, Division 08 openings, and Division 09 finishes. Division 13 special construction items such as pre-engineered structures are tagged where the spec places them there. Foundation quantities are also grouped under Division 31 where earthwork and backfill belong to your scope. Our team uses Bluebeam Revu, PlanSwift, and RSMeans data with ZIP-code-adjusted pricing, so the material and labor rates reflect your market. Turnaround is 24–48 hours for most projects, with rush available.
You need this service when you are bidding a PEMB project and the dealer's quote only covers the building package, when the foundation drawings and the PEMB drawings show different anchor bolt layouts, or when you need a second set of eyes on a scope that crosses trades. We work from the bill of materials on the erection drawings, flag every request for information item, and reconcile the shop drawings against the bid package before we price a line. The takeoff includes marked-up plan sets so you can see exactly where every line item came from. Related scopes like structural steel estimating and miscellaneous metals estimating can be combined into the same package, and concrete estimating services cover the foundation side when you want the slab and footings priced by the same team.

How we build a pre-engineered metal building takeoff
- Anchor bolt reconciliationWe overlay the foundation plan anchor bolt layout against the PEMB column reactions and the anchor bolt plan. Bolt diameter, embedment, projection, and template plate size must match across all three. If the foundation drawings show 3/4 in bolts and the PEMB reactions call for 1 in, we flag it before pricing.
- Primary frame by piece markWe read the erection drawings and bill each rafter, column, endwall post, and crane runway beam by piece mark. Weight comes from the mill-certified schedule or is calculated from section properties. We include connection plates, stiffeners, and field-bolted splice material that is often shown only on the erection sheets.
- Secondary framing and bracingPurlins and girts are taken off by gauge, depth, and span, then extended by bay spacing to get total linear feet and pounds. Flange braces, sag rods, X-bracing, and portal frames at overhead doors are counted from the erection drawings, not the architectural sheets, because that is where they appear.
- Cladding and trimRoof and wall panel areas are measured from elevations and roof plan, then adjusted for panel direction, clip spacing, and end laps. Trim is taken off by profile: eave, rake, corner, base, jamb, head, sill, and gutter. Closure strips and sealants are added at every panel end, eave, ridge, and rake.
- Openings and penetrationsEvery framed opening is counted from the architectural drawings and cross-checked against the PEMB drawings for blocking and trim. Roof curbs for HVAC, exhaust fans, and skylights are taken off with their flashing. We note the structural framing required at each opening, including headers and jamb studs.
- Foundation and slabWe take off spread footings, pier foundations, and slab-on-grade from the foundation plan, including formwork contact area, rebar, vapor barrier, and thickened slabs at column lines. Grout under base plates and leveling nut allowance are added as separate lines. Concrete is priced by ZIP-code-adjusted ready-mix rates.
- Erection and final assemblyErection is priced by crane size and days, ironworker crew days, and equipment. We include torque and bolting, touch-up paint, galvanized repair at field cuts, and final cleaning of panel surfaces. Crane pad or matting on soft subgrade and sales tax and freight are added where the project requires them.

Worked example: takeoff of a PEMB roof panel system
This example shows how we take off a standing seam roof for an illustrative 100 ft × 200 ft PEMB with a 1:12 gable roof. The dimensions are illustrative and do not represent any specific project. We start with the roof plan and elevations from the PEMB drawings.
Step 1: Roof area. The building footprint is 100 ft × 200 ft = 20,000 SF. The roof slope is 1:12, so the slope factor is √(1² + 12²)/12 = 1.0035. The sloped roof area is 20,000 × 1.0035 = 20,070 SF. We round to 20,070 SF. This is the actual surface area to be covered.
Step 2: Panel count. The specified panel is 24 ga standing seam, 16 in wide, with a 2 in major rib. Effective coverage is 16 in = 1.333 ft. The number of panels across the 100 ft width is 100 / 1.333 = 75 panels. Each panel runs the full 200 ft length without end laps. Total linear feet of panel = 75 × 200 = 15,000 LF.
Step 3: Clips. Clips are spaced 24 in o.c. along each panel. The number of clips per panel is 200 ft / 2 ft = 100 clips. Total clips = 75 × 100 = 7,500 clips. We add 5% waste: 7,500 × 1.05 = 7,875 clips, rounded to 7,900.
Step 4: Trim. Eave trim runs along both eave lines: 2 × 200 ft = 400 LF. Rake trim runs along both gable ends: 2 × 100 ft = 200 LF. Ridge cap runs the length of the ridge: 200 ft. Total trim = 400 + 200 + 200 = 800 LF. We add 10% waste for cuts: 800 × 1.10 = 880 LF.
Step 5: Closure strips. Foam closures are required at eave, ridge, and rake. Eave: 400 LF; ridge: 200 LF; rake: 200 LF. Total = 800 LF. Add 10% waste: 880 LF.
Step 6: Sealant. Butyl sealant tape is applied at panel laps and trim joints. Panel laps: 75 panels × 200 ft = 15,000 LF. Trim joints: 800 LF. Total = 15,800 LF. Add 10% waste: 17,380 LF.
Step 7: Fasteners. Each clip requires two fasteners. 7,900 clips × 2 = 15,800 fasteners. Trim fasteners: 880 LF / 1 ft per fastener = 880 fasteners. Total fasteners = 16,680. Add 5% waste: 17,514, rounded to 17,600.
Step 8: Waste factor. We apply waste as a separate line after calculating net quantities. For panels, waste is typically 5–8% for standing seam. For this example, we use 5%: 20,070 SF × 1.05 = 21,074 SF. We round to 21,100 SF.
Step 9: Summary table. The table below shows the final quantities with waste applied as a separate column. All quantities are illustrative.
| Item | Net Qty | Unit | Waste % | Order Qty |
|---|---|---|---|---|
| Standing seam roof panel | 20,070 | SF | 5% | 21,100 SF |
| Clips | 7,500 | EA | 5% | 7,900 EA |
| Eave trim | 400 | LF | 10% | 440 LF |
| Rake trim | 200 | LF | 10% | 220 LF |
| Ridge cap | 200 | LF | 10% | 220 LF |
| Closure strips | 800 | LF | 10% | 880 LF |
| Sealant tape | 15,800 | LF | 10% | 17,380 LF |
| Fasteners | 16,680 | EA | 5% | 17,600 EA |
This takeoff is then priced with ZIP-code-adjusted material and labor rates. The same method applies to wall panels, but with different waste factors and clip spacing. For a complete PEMB takeoff, we extend this to primary and secondary framing, foundation, and openings.
What moves a PEMB cost estimating number
Relative impact on a typical estimate for this trade, based on estimator judgment. Select a bar for details.
Bay spacing
Wider bays reduce the number of frames but increase purlin and girt sizes and may require deeper rafters. A 25 ft bay versus a 30 ft bay changes the secondary framing weight by 10–15 percent on a typical building. We price the bay spacing shown on the erection drawings.
Wider bays reduce the number of frames but increase purlin and girt sizes and may require deeper rafters. A 25 ft bay versus a 30 ft bay changes the secondary framing weight by 10–15 percent on a typical building. We price the bay spacing shown on the erection drawings.
A 1:12 slope uses different panel profiles and closure details than a 4:12 slope. Long clear spans increase rafter depth and weight per square foot. We take these from the PEMB drawings and apply the correct panel and trim profiles.
Vinyl-faced blanket at R-19 is common, but foil-faced or spray foam changes the labor and material line. Long-tab or taped vapor barrier at purlins adds labor. We price the R-value and facing specified, not a default.
Each overhead door, walk door, window, and roof curb requires framing, trim, and flashing. A building with six overhead doors and four roof curbs carries more miscellaneous steel and trim than a warehouse with one door. We count every opening from the schedules.
Crane size, crew days, and matting depend on building height, site access, and subgrade. A 40 ft eave height requires a larger crane than a 20 ft eave. Soft subgrade may require crane mats. We include these as separate line items.
Higher wind speeds or exposure categories increase the number of clips, fasteners, and may require heavier purlins. Seismic zones add bracing and anchorage. We check the adopted code edition with the local building department and price accordingly.
Standard painted finish is common, but galvanized or epoxy coatings add cost. Touch-up paint and field cuts require compatible coatings. We include the specified finish and note any field repair requirements.
Distance from the manufacturer to the site affects freight cost. Oversize loads may require permits and escorts. We add freight as a separate line based on the project location.
Scope gaps we catch in a metal building bid estimating package
PEMB bids fail when the foundation drawings, erection drawings, and architectural sheets disagree. These are the gaps we look for on every project.
- Anchor bolt assemblies and templates are often shown on the foundation drawings, not the PEMB drawings. We reconcile the two and include bolt assemblies in the metal building scope.
- Grout under column base plates and leveling nut allowance are rarely shown on either set. We add them as separate line items with a note.
- Flange braces, sag rods, and wind bracing connections appear only on the erection drawings. We take them off by piece mark and include them in the secondary framing weight.
- Roof and wall insulation, including long-tab or taped vapor barrier at purlins and girts, is often omitted from the dealer quote. We price it by R-value and facing.
- Closure strips, foam closures, and sealants at eave, ridge, rake, and panel ends are small but add up. We count them by linear foot of panel end.
- Gutters, downspouts, splash blocks, and roof drain tie-ins are shown on architectural sheets but missed in metal building bids. We include them with the correct profile and material.
- Framed opening trim — jamb, head, sill, and corner trim around every door and window — is often left to the erector. We take it off from the elevations and schedules.
- Roof curbs for HVAC units, exhaust fans, and skylights, including curb flashing, are added late by the owner. We include them if shown and note if they are pending.
- Fall protection anchors, roof walkway, and roof hatch are often added late by the owner. We flag them as potential change orders if not shown.
- Touch-up paint, galvanized repair at field cuts, and final cleaning of panel surfaces are labor items that erectors sometimes exclude. We include them in the erection scope.
- Erection crane, rigging, and crane pad or matting on soft subgrade are site-specific. We include them as separate lines so you can adjust for your site.
- Sales tax, freight to site, and crane unload at the jobsite are often excluded from dealer quotes. We add them where the project requires.
Cladding and metal building insulation: what changes in the takeoff
The choice of roof and wall cladding and insulation changes the quantity of panels, clips, trim, and labor. This table compares common options by gauge, R-value, and span capability.
| System | Gauge / Thickness | R-value | Span / Application |
|---|---|---|---|
| Standing seam roof | 24 ga | N/A (roof only) | Spans purlins at 5 ft o.c., concealed clips, for low-slope roofs |
| Through-fastened R-panel roof | 26 ga | N/A (roof only) | Spans purlins at 2.5–3 ft o.c., exposed fasteners, for agricultural |
| Insulated metal wall panel | 2 in | R-14 | Spans girts at 5 ft o.c., foam core, for commercial walls |
| Single-skin R-panel wall | 26 ga | N/A (wall only) | Spans girts at 3 ft o.c., requires separate insulation |
| Vinyl-faced blanket insulation | 6 in | R-19 | Installed over purlins and girts, long-tab or taped joints |
| Foil-faced blanket insulation | 4 in | R-13 | Similar to vinyl-faced but with foil facing for radiant barrier |
| Spray foam insulation | 2 in | R-14 | Applied in field, requires closed-cell foam and thermal barrier |
Codes and standards that affect PEMB estimating
Model codes
PEMB projects are governed by the International Building Code (IBC) or International Residential Code (IRC) for residential accessory buildings, with structural provisions referencing ASCE 7 for wind, snow, and seismic loads. The adopted edition varies by state and municipality. The International Energy Conservation Code (IECC) sets minimum R-values for roof and wall insulation, which directly changes insulation quantities and thickness. The National Electrical Code (NEC) applies to lighting and power, affecting Division 26 scope. Always confirm the adopted code edition with the local building department.
Industry standards
Estimators should reference standards from the American Institute of Steel Construction (AISC) for steel design and fabrication, the American Society for Testing and Materials (ASTM) for material specifications (e.g., ASTM A992 for wide-flange shapes, ASTM A653 for galvanized sheet), and the Metal Building Manufacturers Association (MBMA) for PEMB design practices. The American Concrete Institute (ACI) 318 governs concrete foundations and anchor bolt embedment. The Sheet Metal and Air Conditioning Contractors' National Association (SMACNA) provides guidance on metal panel installation. These standards influence material selection and connection details.
Specification sections
CSI MasterFormat sections that drive cost include Division 05 13 00 Pre-Engineered Metal Building Systems (framing, cladding, trim), Division 03 30 00 Cast-in-Place Concrete (foundations, slabs), Division 07 41 13 Metal Roof Panels (gauge, finish, clips), Division 07 42 13 Metal Wall Panels (insulated vs. single-skin), Division 07 21 00 Thermal Insulation (R-value, facing), Division 08 36 13 Sectional Overhead Doors (size, insulation, hardware), and Division 09 29 00 Gypsum Board (interior finishes). Each section's requirements for submittals, testing, and warranties can add cost.
Local amendments
Local jurisdictions may amend the IBC for wind speed, snow load, seismic design category, and energy code requirements. For example, coastal areas often adopt higher wind speed maps, which increase the number of clips, fasteners, and may require heavier purlins. Some states have their own energy codes that exceed the IECC. Always verify the adopted edition and any amendments with the local building department before finalizing the estimate.
Who uses this metal building estimate for contractors
General contractors
You need a complete PEMB scope to compare against dealer quotes and subcontractor bids. Our takeoff gives you a line-by-line breakdown so you can see where the dealer quote is thin and where your erector's bid is missing trim or insulation.
PEMB erectors
You bid erection only and need to know the tonnage, panel square footage, and trim linear feet to price crane days and crew days. Our takeoff gives you the quantities to back into your labor and equipment rates.
Developers and owners
You want a budget before committing to a dealer. Our estimate shows the full installed cost, including foundation, erection, and finishes, so you can compare a PEMB against a conventional steel or tilt-up building.
Architects
You specify the cladding, insulation, and openings and need to know if your details are buildable and priced. Our marked-up plan sets show where we had to make assumptions about trim or flashing.
