TUNNEL BENCHMARKS.
At $1M to $5M, tunnel contractors average 23% gross margin and spend 16% of revenue on overhead, which leaves 7% net profit before taxes (Run On CFOS Trade Benchmark Reference). The CFOS target is 12% net before taxes, the figure the book CONTROL sets for every trade and every revenue band. Getting there means overhead at 15% and gross margin at 27%, and the distance is almost always overhead that was never loaded into the bid.

Showing $1M to $25M. The full data set for every revenue band is on Run On CFOS.
Industry figures are the AVERAGE for the trade at each revenue band, from the Run On CFOS Trade Benchmark Reference, not a floor. Net profit is stated before taxes. The CFOS target is what we build toward. The third column is what companies at $10M to $25M average, shown for direction of travel; that is a larger company, which is a different thing from a better managed one.

TUNNEL GROSS MARGIN.
How to calculate: Gross margin is Revenue minus Direct Job Costs, divided by Revenue, times 100. Direct job costs include labour, materials, equipment and subcontracted work tied to the job. Not shop overhead, office staff or G and A.
In tunneling the advance rate against daily cost is the entire margin, which puts the four points between the trade average and the target at $40,000 on a $1M year and $200,000 on a $5M year. Cutter and consumable burn changes with the material being cut, grout takes move with the formation, and none of that's legible in a monthly job total. The tunnel gross figure at this revenue is derived from the nearest comparable trade in the SPM 48-trade dataset rather than measured directly, so read it as a reference point while your own per-foot history builds. Advance rate and consumable burn tracked by geotechnical class is the measurement, and in the small-diameter segment where most mid-market contractors live it's per-foot pricing or it's guessing.
GROSS MARGIN BY REVENUE BAND, $1M TO $25M
| REVENUE BAND | INDUSTRY AVERAGE | CFOS TARGET |
|---|---|---|
| $1M to $5M | 23% | 27% |
| $5M to $10M | 24% | 26% |
| $10M to $25M | 25% | 25% |
The gross margin figures for tunnel are derived from the nearest comparable trade in the same dataset, so treat them as a reasonable starting point and not a survey result.
TUNNEL OVERHEAD RATE.
How to calculate your overhead rate: Total overhead divided by Total Revenue, times 100. Overhead is every cost not attributable to a job: office staff, rent, insurance, software, vehicles not charged to work, and owner salary. It moves every month with revenue, which is why a rate set a year ago is wrong in both directions.
In tunneling the plant is the 16 percent overhead rate, and the point down to 15 is worth $10,000 on a $1M year and $50,000 on a $5M year. Separation, ventilation, hoisting, and segment handling equipment rivals the boring machine itself in cost, and shaft economics bookend every drive whether it is 200 feet long or 2,000. The tunnel overhead figure at this revenue is derived from the nearest comparable trade in the dataset rather than measured directly, so build your own before you price a drive against it. Charging plant and shaft cost to the drive that used them is the move, and the trade should reach 13 percent by $25M to $50M.

|---|---|---|
| $1M to $5M | 16% | 15% |

| $10M to $25M | 14% | 13% |

TUNNEL NET PROFIT MARGIN.
Net profit margin formula: Net Profit divided by Total Revenue, times 100. Unlike gross margin this measures what is left after overhead and G and A. It's the number that funds owner draw, debt paydown and growth.
In tunneling the argument over a stopped heading decides the five points to a 12 percent before tax target, worth $50,000 on a $1M year and $250,000 on a $5M year. The burn rate never sleeps, so every hour the face isn't advancing costs full crew, power, and plant, and whether that hour is yours or the owner's depends entirely on what the daily log says. Payment is based on advanced meters and installed lining verified below the surface, with survey, ring records, and grout takes substantiating every pay item. Documentation is the product's second half in this trade, and the five points are in hours nobody attributed.
NET PROFIT MARGIN BY REVENUE BAND, $1M TO $25M

|---|---|---|

Benchmarks for subcontractors from $1M to $25M. This is a partial view of the Run On CFOS benchmark reference, which covers every band up to $500M and above. The full Run On CFOS benchmark reference is on runoncfos.com.
Gross margin and overhead come from figures CFMA, Jones Maresca and other sources publish by trade and size. Net profit is computed, not surveyed: net profit = gross margin minus overhead. Nothing comes out for taxes, interest or other income and expense, so it is a before tax figure, on the same basis as CFMA's net income before taxes.
CFMA's 2025 medians are 7.1 percent before interest and taxes and 6.7 percent net income before taxes. Gross margin minus overhead leaves out interest and other income and expense, so a figure here can come in a little above or below a reported net income on the same business. The bands above the $10M to $25M band are published at runoncfos.com as a modeled extension of the same curves. They have not been reconciled against the licensed CFMA Benchmarker, so read them as a model and not as a survey result.
Trade figures are from the Run On CFOS Trade Benchmark Reference, published by Sulphur Prairie Operations, LLC. Net profit is stated before taxes. CFMA reports net income before taxes too, so the two read on the same basis. Re-validate against CFMA reporting on the normal quarterly cycle, per the benchmark reference's own instruction.
The reference itself is published at tunnel gross margin in the reference itself. The sourcing note behind the 48 trade set is set out at runoncfos.com.
