Steel Erection Estimate Template
Download a steel erection estimate template to calculate erection labor, cranes, lifts, welding, rigging, equipment, overhead, profit, and bid pricing.
Build Detailed Steel Erection Estimates From Tonnage Through Final Price
A steel erection estimate gives structural steel contractors a structured way to calculate erection labor, cranes, aerial lifts, welding, bolting, rigging, temporary bracing, decking, equipment, mobilization, subcontractors, overhead, and profit before submitting a bid. Breaking the work into erection sequences and measurable assemblies makes it easier to account for building height, piece count, crane reach, connection complexity, access, and project phasing.
This Steel Erection Estimate Template is designed for structural steel erectors, miscellaneous metals contractors with erection crews, steel subcontractors, estimators, project managers, operations managers, and construction business owners.
What Is a Steel Erection Estimate?
A steel erection estimate is an internal pricing document used to calculate the expected cost of unloading, staging, hoisting, connecting, plumbing, aligning, bolting, welding, decking, temporary bracing, crane operations, access equipment, mobilization, supervision, and related field work. Depending on the project, it may also include joists, joist girders, stairs, rails, ladders, embeds, miscellaneous framing, loose steel, and other erection responsibilities.
Steel tonnage is important, but it is not the only production driver. A low-rise warehouse with repetitive bays and good crane access can require a different erection plan than a multistory frame with tight access, numerous small pieces, complex connections, multiple crane setups, or extensive field welding. A useful estimate keeps tonnage, piece count, connection type, elevation, crane requirements, and labor productivity visible.

How to Use the Template
- Enter the customer, project, estimate number, bid date, drawings, specifications, addenda, estimator, and schedule information.
- Break the erection scope into areas, levels, sequences, grid lines, structural assemblies, or another location system that matches the project.
- Enter steel tonnage and piece counts for columns, beams, girders, joists, braces, stairs, miscellaneous framing, and other included steel.
- Identify connection types and estimate bolt-up, field welding, plumbing, alignment, and connection labor separately where useful.
- Build labor hours using crew size and production assumptions appropriate for the building height, piece size, connection complexity, crane access, and erection sequence.
- Estimate crane requirements using anticipated picks, piece weights, working radius, setup locations, operating duration, mobilization, and standby assumptions.
- Add boom lifts, scissor lifts, telehandlers, welding equipment, generators, rigging, temporary bracing, and other support equipment.
- Estimate metal deck, bridging, stairs, rails, miscellaneous metals, or loose steel separately when those items are part of the erection package.
- Add project management, supervision, travel, per diem, consumables, testing, subcontractors, remobilization, and other indirect costs where applicable.
- Separate base scope from allowances, alternates, unit prices, exclusions, and work by others before applying overhead, profit, and applicable taxes.
A steel erector prices a two-story commercial building with 285 tons of structural steel, approximately 1,050 primary steel pieces, 48 tons of joists and joist girders, and 92,000 square feet of metal deck. The estimate separates column and beam erection, joist placement, bridging, deck installation, bolt-up, field welding, plumbing and alignment, crane mobilization, two crane setup areas, boom lifts, telehandlers, rigging, temporary bracing, supervision, and punch work. A separate alternate covers weekend erection requested to accelerate the structural schedule.
Best Practices for Steel Erection Estimates
- Use current structural drawings, specifications, addenda, connection information, and available erection sequencing documents.
- Track both steel weight and piece count rather than relying on tonnage alone.
- Separate repetitive framing from complex or high-labor steel assemblies.
- Review connection types and field-welding requirements before assigning labor productivity.
- Check crane capacity and working radius assumptions against planned setup locations and anticipated piece weights.
- Include crane mobilization, demobilization, setup, standby, and additional mobilizations where applicable.
- Account for access equipment by crew, level, or erection phase rather than carrying one broad allowance.
- Identify temporary bracing, plumbing, alignment, deck closures, openings, and punch work.
- Adjust production assumptions for building height, congestion, restricted access, winter conditions, night work, or phased erection.
- Use completed-job labor hours, crane hours, piece counts, and tonnage to refine future estimates.
Common Steel Erection Estimating Mistakes
- Pricing the entire frame from steel tonnage without reviewing piece count
- Failing to distinguish simple bolted framing from connection-heavy or field-welded work
- Underestimating crane setup, relocation, mobilization, or standby time
- Ignoring crane reach and working-radius constraints
- Omitting unloading, staging, shakeout, and material handling
- Failing to include boom lifts, telehandlers, welders, generators, and support equipment
- Omitting temporary bracing, plumbing, alignment, bridging, or punch work
- Using open-site production rates for congested, multistory, or restricted-access work
- Failing to account for remobilization, overtime, travel, per diem, or schedule acceleration
- Submitting pricing without clearly documenting scope boundaries, exclusions, and work by others
Frequently Asked Questions
What should be included in a steel erection estimate?
Include erection labor, cranes, aerial lifts, rigging, bolting, welding, temporary bracing, unloading, staging, equipment, supervision, mobilization, subcontractors, consumables, indirect costs, overhead, and profit as applicable to the project.
Should steel erection be estimated by ton or by piece?
Both can be useful. Tonnage helps measure overall steel volume, while piece count can better reflect the number of picks, connections, and handling operations. Many estimates benefit from reviewing both measures together.
How should crane cost be estimated?
Estimate the required crane type and capacity, setup locations, working radius, operating hours or days, mobilization, demobilization, operator requirements, expected relocations, and likely standby. Use current crane-vendor pricing when the crane is subcontracted or rented.
How should steel erection labor productivity be estimated?
Use production assumptions that reflect steel weight, piece count, building height, connection type, crane access, staging, work sequence, crew composition, and project-specific restrictions. Historical completed-job data can provide a useful estimating reference.
Should field welding be estimated separately?
It is often useful to separate field welding when it is a meaningful part of the work. Track weld location, connection type, quantity, expected labor, access requirements, equipment, consumables, and any project-specific inspection or testing responsibilities.
How should metal deck be estimated?
Track deck by area, type, gauge or designation, level, edge condition, openings, closures, fastening or welding requirements, equipment access, and labor. Separate roof and floor deck when their installation conditions differ.
What steel erection unit prices are useful?
Useful internal or customer-facing unit prices may include erection by ton, steel piece, square foot of deck, crane hour, lift day, field-welding hour, or miscellaneous steel item, depending on the scope and contract structure.
Can the estimate become the job budget after award?
Yes. The approved estimate can provide a baseline for labor hours, crane time, access equipment, erection sequences, subcontract commitments, change management, and job-cost review.
Turn Steel Quantities and Erection Logistics Into Reliable Pricing
A structured steel erection estimate connects tonnage and piece count with crews, crane requirements, connection work, access equipment, temporary measures, logistics, and project-specific assumptions before the bid is submitted.
A spreadsheet is a practical starting point for repeatable estimating. As estimate volume grows, construction management software such as SimplySub can help connect estimates with customers, jobs, and job-cost information.
