How is steel detailing priced in the US?
Steel detailing in the US is priced four common ways: by the hour, by the ton of steel, by the drawing sheet, or as a fixed fee for a defined scope. Each method puts the risk of extra hours on a different party, and each can look cheaper or more expensive depending on how complex the steel is.
| Pricing model | How it works | Works well when | Watch for |
|---|---|---|---|
| Hourly | Estimated hours at an agreed rate, billed on hours worked | Documents are incomplete, design changes are expected, or scope is mixed | How hours are estimated, tracked and reported |
| Per ton | A price per ton of steel detailed | Repetitive structural framing where weight tracks effort | Misc steel and complex connections, where effort per ton is much higher |
| Per sheet | A price per drawing sheet | Scope with predictable, standardized sheets | Sheet counts depend on how details are split across sheets |
| Fixed fee | A lump sum for a defined scope and deliverables | Complete, coordinated documents and a clearly bounded scope | What counts as a change, and how changes are priced |
No model is dishonest by itself. Problems arise when a quote's basis does not match the job: a per-ton price on a stair-and-rail package, or a fixed fee on documents that are still changing.
What drives the cost of a steel detailing package?
Detailing cost follows detailing hours, and hours follow complexity rather than weight. Connection complexity, the density of miscellaneous steel, irregular geometry, incomplete contract documents, revisions, compressed schedules and the deliverables required all add hours. Repetition, complete documents and established shop standards take hours away.
| Cost driver | Why it adds hours |
|---|---|
| Connection complexity | Moment, skewed, sloped and thermally broken connections each need individual geometry and checking |
| Miscellaneous steel density | Stairs, rails, ladders and embeds are many unique parts, each with its own detail |
| Irregular geometry | Skewed grids, sloped members and curved framing reduce what can be copied |
| Incomplete contract documents | Gaps create RFIs, holds and rework |
| Revisions | Design changes during detailing force re-modeling, re-checking and reissue |
| Schedule compression | Resequencing work and parallel releases add coordination time |
| Deliverables required | Erection drawings, NC files, bolt lists and submittal packaging each take time |
| Special conditions | Structural thermal breaks, galvanizing details and field-verified conditions add steps |

What does in-house steel detailing cost per hour?
An in-house US steel detailer is estimated to cost about $45–$90 per productive hour once salary, payroll taxes, benefits, equipment and non-project time are counted, before a software seat. These are illustrative industry estimates built from stated assumptions, not quotes and not claims about any company; substitute your own payroll figures to get your number.
| Cost item | Assumed annual range |
|---|---|
| Base salary, US steel detailer | $60,000–$90,000 |
| Payroll taxes, health insurance and retirement (assumed 25–35% of salary) | $15,000–$31,500 |
| Workstation, IT and training | $2,000–$5,000 |
| Detailing software seat (SDS/2 or other) | Vendor-quoted; excluded from the totals |
| Total before software | $77,000–$126,500 |
| Productive detailing hours per year after holidays, PTO and non-project time (assumed) | 1,400–1,700 |
| Cost per productive hour before software | About $45–$90 |
The arithmetic: $77,000 ÷ 1,700 hours ≈ $45 per hour, and $126,500 ÷ 1,400 hours ≈ $90 per hour.
The hourly figure understates one thing: an in-house detailer's cost continues when the backlog is empty. For a fabricator whose detailing demand rises and falls with bid season, idle weeks raise the real cost per hour actually used.
Why are offshore detailing rates lower?
Offshore detailing rates are lower mainly because salaries and overhead in countries such as India are lower than the loaded cost of detailers in the US. A lower rate does not by itself mean a different standard: drawings for US projects should still follow AISC 303, AISC 360, imperial units and US drawing conventions. What changes is the delivery model.
The offshore tradeoffs are real and should be priced in: a time-zone offset that limits same-hour answers, written rather than in-person communication, and onboarding to your shop standards. The guide to outsourcing steel detailing covers those risks and how to manage them. Rates at onshore detailing firms vary by firm and region and are generally higher than offshore rates.
How do you compare two detailing quotes fairly?
Compare detailing quotes on the same scope, the same deliverables and the same assumptions about revisions, not on the headline number. Two quotes can differ by a wide margin simply because one includes erection drawings, NC files and a round of revisions and the other does not. Ask each firm the same questions and put the answers side by side.
| Question to ask | Why it matters |
|---|---|
| What is the pricing basis: hour, ton, sheet or fixed fee? | Determines who carries the risk of extra hours |
| Which deliverables are included? | Erection drawings, NC files, bolt lists and submittal packaging are not always included |
| How are revisions and design changes billed? | Revision terms often decide the final cost |
| Who checks drawings before release, and against what? | Checking limits rework and field fixes |
| How are RFIs handled and logged? | Unmanaged RFIs become schedule and cost problems |
| What schedule is assumed, and what happens if documents change? | A low price on an unrealistic schedule is not a low price |
| Which software and file formats are used? | Matters if you need native models or specific NC formats |
How do hours and rates turn into a package cost?
A package's detailing cost is its estimated hours multiplied by the hourly rate, which is why the hour estimate matters as much as the rate. The example below is hypothetical, for arithmetic only; it is not a typical package size. Real hours depend entirely on the scope, complexity and documents of your project.
| Hypothetical package | Hours | Rate | Detailing cost |
|---|---|---|---|
| 80 hours at the low end of Vertex's range | 80 | $15 | $1,200 |
| 80 hours at the high end of Vertex's range | 80 | $20 | $1,600 |
| 80 hours at an estimated in-house cost | 80 | $45–$90 | $3,600–$7,200 |
Per-ton or per-sheet quotes cannot be converted to hours without knowing the effort behind them, so ask firms quoting on those bases what hours they have assumed. Vertex's own rate and what moves a package within it are on the steel detailing rates page.
How can you reduce what steel detailing costs?
You reduce detailing cost by reducing hours, and most of the levers sit with you rather than the detailer: send complete, coordinated documents, provide shop standards up front, answer RFIs quickly, standardize repeated miscellaneous items, avoid design changes after detailing starts, and set schedules that leave room for normal review cycles.
- Send contract drawings, specifications and addenda together, not in pieces
- Provide shop standards or approved drawings before modeling begins
- Answer RFIs quickly and in writing, with sheet references
- Standardize stair configurations, rail post spacing and embed types where the design allows
- Release the design for detailing once it is stable
- Phase releases, such as embeds first, instead of compressing everything into one date
Frequently asked questions
Is per-ton or hourly pricing cheaper for steel detailing?
It depends on the job. Per-ton pricing can be economical on repetitive framing where weight tracks effort. Hourly pricing is more transparent when documents are incomplete, design is still changing, or the package is heavy on miscellaneous steel.
Why don't most detailing firms publish a price?
Per-ton and fixed-fee prices depend on scope, so many firms quote only after reviewing drawings, which is reasonable. An hourly rate can be published because the uncertainty sits in the hours, which are estimated from the documents.
Does steel detailing cost include revisions?
It depends on the quote. Some include a round of approval comments; design changes after detailing starts are often billed separately. Ask how revisions are billed before comparing prices.
What does Vertex charge for steel detailing?
$15–20 USD per hour, varying with connection complexity, miscellaneous steel density, revision volume and turnaround pressure. See steel detailing rates.
