STRUCTURE & ENVELOPE CLUSTER · CFOS TRADE OPERATING SYSTEM

WHY STRUCTURAL STEEL CONTRACTORS LOSE MARGIN WITHOUT KNOWING IT.

QUICK ANSWER

Structural Steel margin is lost to three specific things: the paper gate, the idle crane, and the ton tape. Structural Steel subcontractors at $1M to $5M run 23 percent gross and 6.5 percent net, against CFOS targets at $1M to $5M of 24 percent gross and 10 percent net. All three are measurable, and all three are invisible without job costing that reads against the estimate.

Structural steel contractors at $1M to $5M net 6.5 percent, rising to 9.5 percent by $25M to $50M; the CFOS target at $1M to $5M is 10 percent. The distance between the trade average and the CFOS target isn't a pricing problem in this trade. It sits in the three mechanisms below, each of which moves margin without appearing as a failure on any single job. Nothing fabricates until shop drawings clear the EOR, and most rejections trace to coordination gaps the fabricator controls. Every review cycle moves the mill order, the delivery, and the crane schedule, and the detailing phase is billed or it's donated.

THE THREE BIG LEAKS

THE MATH BEHIND THE MISSING CASH.

LEAK 01

The Paper Gate

Nothing fabricates until shop drawings clear the EOR, and most rejections trace to coordination gaps the fabricator controls. Every review cycle moves the mill order, the delivery, and the crane schedule, and the detailing phase is billed or it's donated.

LEAK 02

The Idle Crane

The most expensive spread on the project idles when foundations, inspections, or access aren't ready, and erection crews are rarely the cause. Crane cost coded by lift plus same-day standby documentation converts the GC's unreadiness into a claim instead of a loss.

LEAK 03

The Ton Tape

Steel up 18 percent in a year on tariffs, fabrication benchmarked at $1,800 to $3,200 per ton, sold into fixed-price contracts. Without escalation clauses and dated price bases, the steel contractor is trading commodities with a crane. (cfos-job-profitability-system) ---

HOW CFOS FIXES IT

WHAT CHANGES IN THE FIRST 60 DAYS.

The shop-drawing gate (nothing fabricates until paper approves)
Steel price and fabrication cost (the 2026 tape)
The crane clock (the most expensive hour on site)
Erection stability and the Subpart R burden
The fab/erect split (one contract, two businesses)

Industry figures are Structural Steel contractors' AVERAGE for each revenue band, not a floor. The CFOS net profit target is set at 10 percent before taxes or 3.5 points better than your trade's average at your revenue, whichever is higher, and the gross margin target is set at whatever gross margin produces that net profit once your overhead is paid, and never below your trade's own average. Gross minus overhead equals net on every column, so the rows tie out.

Range reflects the three tiers below. Which one you're in depends on how much of the work you want off your desk. No payroll. No hidden line items.

Core

You stop guessing.

You get the CFO work. Job costing built against the way you estimate, a 13 week cash forecast, monthly WIP, and a meeting every month that ends in decisions rather than a report.

Your bookkeeper keeps doing the books.

Executive

You stop touching the books.

Everything in Core, and we run the bookkeeping and the controllership as well. Nobody in your office is answering coding questions or chasing a reconciliation at month end.

We do the books. No payroll.

Strategic

Every job shows its margin while it's still running.

Everything in Executive, plus the job costing and WIP platform set up, loaded with your cost codes, and managed for you every month. You never have to learn it.

We do the job costing.

COMMON QUESTIONS

FREQUENTLY ASKED.

Structural steel contractors at $1M to $5M net 6.5 percent on average, rising to 9.5 percent by $25M to $50M; the CFOS target at $1M to $5M is 10 percent. The trade's margins are among the healthier on the site; the cash timing around detailing, fabrication, and crane schedules is where companies bleed. Every net profit figure here is stated before taxes, the same basis CFMA reports on, so the two are directly comparable.
Every review cycle pushes fabrication release, mill delivery, and the crane schedule downstream, and most rejections trace to coordination gaps and missing connection information the detailing team controls. Bill detailing as its own SOV line, put approval milestones on the cash forecast, and run internal QC against the current AISC standard before submission.
The paper decides. Industry delay analysis is blunt: foundations, inspections, and access cause most erection delays, not erection crews. Code crane cost by lift, document site-readiness failures the day they happen, and the standby claim writes itself; skip the documentation and the erector donates the most expensive hours on the project.
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 hides which side earns and misprices both, and on subcontracted splits the contract interface is where the schedule risk lives.
Date-stamp the price basis, carry an escalation clause indexed to a published steel reference, and buy out mill orders early on long jobs. Steel moved about 18 percent in a year on tariffs; a fixed bid without a clause is an unhedged position measured in tons.
A bookkeeper records history. SOV-billed detailing, crane cost codes, standby documentation, escalation clauses, and divisional tracking are a control system, which is CFO work. SPM operates that financial control function for structural steel contractors. ---
CFOS serves commercial structural steel subcontractors doing $1M to $12M. Pricing starts at $1,900 per month for companies under $1M and runs to $13,500 per month at the top published band. Onboarding takes 60 days.
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. Executive is where you stop touching the books, because we run the bookkeeping and the controllership as well. Strategic is where every job shows its margin while it is still running, because the job costing and WIP platform is set up and managed for you. No payroll. No scope gaps.
