ONE PROBLEM, IN DETAIL

CONNECTION COUNT JOB COSTING: ERECTION STABILITY AND THE SUBPART R BURDEN

QUICK ANSWER

OSHA Subpart R and AISC's Code of Standard Practice put erection-phase stability on the erector: temporary bracing until the permanent system is in (COSP 7.10), minimum-bolt rules before releasing crane load, plumb tolerances (1:500).

Rather talk it through first? Book a 20 minute call. Nothing gets sold on this call.

Want it set up for you? Onboarding only, from $4,500 one time. Books migrated and job costing built, then your own team keeps it up.

WHAT BREAKS

WHERE THE MONEY GOES.

Erection stability and the Subpart R burden

OSHA Subpart R and AISC's Code of Standard Practice put erection-phase stability on the erector: temporary bracing until the permanent system is in (COSP 7.10), minimum-bolt rules before releasing crane load, plumb tolerances (1:500). Connection details drawn for structural efficiency without erection sequence in mind create field hazards and rework, and the erector absorbs the field fix unless the paper trail points back at the detailer.

WHAT THE NUMBERS SAY

THE COST, SOURCED.

Sourced language

"Fabricators who design connections purely for structural efficiency without considering erection sequence create field safety hazards and OSHA citation exposure." (2026 fabrication guide) "The erector is responsible for stability until the permanent system is in place." (AISC COSP 7.10 summary)

WHAT THIS TRADE SHOULD EARN

THE NUMBER TO MEASURE IT AGAINST.

Structural Steel contractors have about 8% net profit at $1M to $5M, rising to roughly 10% at $5M to $10M. The CFOS net profit target is 11.5% before taxes at $1M to $5M, the trade's average plus 3.5 points, never below 10%. A problem like this one lives in the distance between those two figures rather than in a loss on any single job.

Gross margin over the same bands is 23% to 24%,against CFOS targets of 25.5% and 26.5%.

THE SYSTEM THAT FIXES THIS.

Job Profitability System

Cost codes built against the estimate, so a job can be read while it is open.

COMMON QUESTIONS

FREQUENTLY ASKED.

Yes, as divisions. Fabrication is tons through a shop with AISC certification as the market's credibility floor; erection is crews, cranes, and weather. One blended P&L conceals which side earns and misprices both, and on subcontracted splits the contract interface is where the schedule risk lives.

Three tiers, and which one you are in depends on how much of the work you want off your desk. Core is where you stop guessing: job costing built against the way you estimate, a 13 week cash forecast, monthly WIP, and a monthly meeting that ends in decisions, while your bookkeeper keeps doing the books. Strategic is where every job shows its margin while it is still open: a bookkeeper we choose does the books and the bank reconciliations, and the job costing and WIP software is set up and managed for you, on your own online software or ours. Platinum is where you approve and the money side gets handled: a controller we choose handles your bills and receivables the way an in-house controller would, and you approve every payment. No payroll. No scope gaps.

Sixty days. We migrate your books back to the start of your last taxable year and build your job costing structure from scratch, and on Strategic and Platinum we set up the job costing and WIP software too. Fully operational in two months. The onboarding fee is one time, the same for every tier, and set by your revenue band.
