TL;DR: Concrete Flatwork contractors at $1M-$12M in commercial new construction target 19-24% gross margin. Under $1M the target is 22-27% because overhead is a higher percentage of revenue at lower volume. Gross margin below the lower end of the range almost always has an identifiable cause: markup confusion, overhead rate understatement, or job costing that blends high-cost and low-cost work types into a single rate.

Benchmark Table
Concrete Flatwork Gross Margin by Revenue Band
These benchmarks apply to commercial new construction work. Maintenance contracts, service work, and residential work have different margin structures. Gross margin below the lower end of any band almost always has an identifiable fix.
| Revenue Band | Gross Margin Target | Typical Overhead Rate | Target Net Profit |
|---|
| Under $500K | 24-27% | 16-22% | 6-10% |
| $500K-$1M | 22-27% | 14-18% | 6-10% |
| $1M-$3M | 19-24% | 13-16% | 7-10% |
| $3M-$6M | 19-24% | 12-15% | 7-11% |
| $6M-$12M | 18-22% | 11-14% | 7-11% |
FAQ
Frequently Asked Questions
What is a good gross margin for concrete flatwork contractors?
Concrete Flatwork contractors at $1M-$12M in commercial new construction typically target 19-24% gross margin. Under $1M revenue the target is higher at 22-27% because overhead as a percentage of revenue is greater at lower volume. At $6M-$12M the target compresses slightly to 18-22% as overhead dilutes with scale.
Why do concrete flatwork contractors have lower gross margins than expected?
Three consistent causes: markup confusion where 20% markup is mistaken for 20% margin (it is actually 16.7%), overhead rate understatement where SG&A is missing owner compensation at market rate or equipment depreciation, and job costing that does not separate cost by work type allowing high-cost work to be priced at average rates. Pump cost allocation is the most common gross margin distortion in concrete flatwork. When pump rental and operator cost is booked to overhead rather than allocated to specific pours the cost per SF on elevated pours appears artificially low. Elevated deck priced at parking lot rates is the fastest way to compress flatwork margins.
How does concrete flatwork job costing improve gross margin?
By making cost per unit visible by work type weekly rather than at closeout. Pour size affects production rate and therefore cost per SF significantly. A 5,000 SF parking lot pour and a 400 SF mechanical equipment pad both use the same mobilization cost. The mechanical pad costs more per SF in overhead allocation. Blending small and large pours in estimating understates the cost of miscellaneous work. SPM builds ControlQore cost codes aligned to the concrete flatwork estimate structure so actual cost per unit posts weekly against estimated rate.
What overhead rate should a concrete flatwork contractor use?
Concrete Flatwork contractors typically run 12-17% overhead depending on revenue level. The overhead rate must include full owner compensation at market rate, vehicle fleet, equipment depreciation, and technology costs. Understating any of these understates the overhead rate and underprices every bid.
