TRADE SERVICE · STRUCTURE & ENVELOPE CLUSTER

FRACTIONAL CFO FOR STRUCTURAL STEEL CONTRACTORS.

QUICK ANSWER

We run the finance function for structural steel subcontractors doing $1M to $12M: job costing aligned to the way you estimate, a 13 week cash flow forecast, monthly WIP, and a CFO in the room every month. Pricing starts at $1,900 per month.

In structural steel nothing gets fabricated until paper clears the engineer of record, so the detailing phase is either billed or donated. AISC's Code of Standard Practice puts shop and erection drawings on the fabricator, most rejections trace to incomplete coordination and missing joint detail, and every review cycle moves the mill order, the delivery, and the crane schedule with it. We code crane cost by lift and document standby the same day, because the most expensive spread on the project idles for foundation problems, incomplete inspections, and poor access, and erection crews are rarely the cause. Then we split fabrication from erection into two P&Ls and put a dated price basis with escalation into the contract, since steel moved roughly 18 percent in a year on layered tariffs against fabrication benchmarked at $1,800 to $3,200 a ton.

WHERE STRUCTURAL STEEL LOSES MONEY

THE THREE THINGS THAT DRAIN THE 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) ---

WHAT WE CHANGE.

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)

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.

Prevailing wage note: Structural Steel work often runs on public bids, which means certified payroll and wage classifications have to line up with the job cost record. ControlQore holds the classification against the cost code, so the certified report and the job cost report come from the same data instead of somebody keying the same numbers twice every week.

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.
