ONE PROBLEM, IN DETAIL

CIVIL: CHANGED CONDITIONS AND THE EXCESS DIRT DISPUTE

QUICK ANSWER

The ground never matches the geotech report. Quantities move, hauling distances grow, and the change order dispute starts after the cost is already spent.

This page covers one problem. The full picture for this trade, including the other places margin leaks, is on the civil operating system page.

WHAT BREAKS

WHERE THE MONEY GOES.

Changed conditions and the excess dirt dispute

Covered in full in the quick answer above. The sourced numbers and what controls it are below.

Rock, spoil, and the changed-conditions dispute

The ground never matches the report. D2 Excavating v. Thompson Thrift started as a $630K excavation subcontract, produced far more spoil than planned, and ended at the Fifth Circuit with a judgment for the sub above half a million dollars. The cost is spent before the dispute starts.

WHAT THE NUMBERS SAY

THE COST, SOURCED.

WHAT THIS TRADE SHOULD EARN

THE NUMBER TO MEASURE IT AGAINST.

Civil contractors have about 7% net profit at $1M to $5M, rising to roughly 10% at $5M to $10M. The CFOS net profit target is 10.5% 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 21% to 23%,against CFOS targets of 23.5% and 25.5%.

COMMON QUESTIONS

FREQUENTLY ASKED.

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.
