CIVIL & EARTHWORK CLUSTER · CFOS TRADE OPERATING SYSTEM

WHY DEMOLITION CONTRACTORS LOSE MARGIN WITHOUT KNOWING IT.

QUICK ANSWER

Demolition margin is lost to three specific things: the survey skipped, the gate rate, and the untracked paycheck in the pile. Demolition subcontractors at $1M to $5M run 20 percent gross and 5.5 percent net, against CFOS targets at $1M to $5M of 25 percent gross and 10 percent net. All three are measurable, and all three are invisible without job costing that reads against the estimate.

Demolition contractors at $1M to $5M net 5.5 percent, rising to 8.5 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. Hazmat discovered mid-swing stops the machine and adds $2 to $7 per square foot under abatement protocol. The pre-demolition survey is a billed line and a change-order trigger, or it's the most expensive thing the contractor never charged for.

THE THREE BIG LEAKS

THE MATH BEHIND THE MISSING CASH.

LEAK 01

The Survey Skipped

Hazmat discovered mid-swing stops the machine and adds $2 to $7 per square foot under abatement protocol. The pre-demolition survey is a billed line and a change-order trigger, or it's the most expensive thing the contractor never charged for.

LEAK 02

The Gate Rate

Disposal runs 20 to 30 percent of project cost, and tipping fees moved about 10 percent in a year to roughly $62 per ton. Per-ton actuals tracked against the bid rate is the trade's simplest, highest-value variance report.

LEAK 03

The Untracked Paycheck in the Pile

Salvage is contract consideration: ferrous drives the tonnage, non-ferrous drives the margin, and disputes go to court. A per-job scrap ledger with grading, weights, and settlement documentation turns a guess into revenue. (cfos-job-profitability-system) ---

Tipping fees eat 20 to 30 percent of the job
Salvage is revenue and it belongs on the estimate

Industry figures are Demolition 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.

Demolition contractors at $1M to $5M net 5.5 percent on average, rising to 8.5 percent by $25M to $50M; the CFOS target at $1M to $5M is 10 percent. The margin leaks in three places: unbilled hazmat discoveries, tipping fee drift, and salvage revenue nobody reconciles. Every net profit figure here is stated before taxes, the same basis CFMA reports on, so the two are directly comparable.
The contract decides, which is why the pre-demolition survey and a hazmat discovery clause belong in every bid. Discovery stops work, triggers licensed abatement at $2 to $7 per square foot over baseline, and without a documented change-order process the demo contractor eats the delay while the abatement sub gets paid.
Bid the current gate rate per ton with a dated basis, track actual tons and actual rates per job, and reconcile the variance weekly. Disposal is 20 to 30 percent of the job and the national average moved about 10 percent in a year; a stale rate assumption donates the increase on every load.
Three ways: the contractor keeps scrap and bids lower, scrap gets credited against the invoice, or a recycler grades and settles. Courts treat salvage as part of the contract consideration, so name the structure in writing and keep a per-job ledger of grades, weights, and settlements; ferrous carries the tonnage, non-ferrous carries the margin.
Because the trade carries the heaviest iron per revenue dollar in the dirt group: excavators with shears and processors, lowboys, service trucks, and a yard. At 16 percent overhead against a 20 percent gross margin at the small end, equipment cost allocation is the whole ballgame.
Yes, as separate cost histories. Full structural work is machine production at $9 to $22 per square foot by class; selective demo is hand labor, protection, and dust control. One blended history misprices both and hides which division earns its keep.
A bookkeeper records history. Survey billing, hazmat change-order protocol, tipping variance tracking, salvage ledgers, and equipment allocation are a control system, which is CFO work. SPM operates that financial control function for demolition contractors. ---
CFOS serves commercial demolition 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.
