Which sheet pile installation expenses are fixed, and which move with project volume?

Cost classification

Break-even is only useful if each expense follows the right driver. Yard rent and insurance stay in overhead, while steel, fuel, mobilization, and testing move with job volume.

Expense	Cost	Break-Even Treatment	Common Mistake
Equipment Storage Yard Rent	Fixed	Include the $12,500 monthly yard rent in fixed overhead from Month 1 through Month 60.	Treating yard space as project-only when it’s needed before and between jobs.
General Liability and Marine Insurance	Fixed	Include the $15,000 monthly insurance charge in overhead before calculating required project revenue.	Ignoring marine coverage until backlog is signed.
Crew Wages	Semi-fixed	Include core first-year payroll at about $83,583 per month, then step it up as operators and pile drivers are added.	Assuming idle days disappear just because billable hours rise.
Steel Material Procurement	Variable	Model steel at 15.0% of first-year revenue, falling to 13.0% by the fifth year.	Burying steel price swings inside overhead.
Equipment Fuel and Lubricants	Variable	Model fuel and lubricants at 6.0% of first-year revenue, then 5.2% by the fifth year.	Using old fuel quotes after marine access or haul distance changes.
Project Mobilization Logistics	Variable	Model mobilization logistics at 5.0% of first-year revenue, tied to hauling, setup, and project location.	Underpricing transport, crane setup, and site access time.
Heavy Equipment Maintenance Contract	Fixed	Include the $8,000 monthly maintenance contract in fixed overhead.	Confusing planned service with repair overruns.
Subcontracted Geotechnical Testing	Variable	Model testing at 4.0% of first-year revenue, linked to required project scope.	Forgetting required test scope in bid pricing.

How does break-even change from a lean core crew to a full multi-crew sheet pile operation?

Scenario table

Break-even rises as the model scales, because revenue and contribution improve, but fixed payroll, yard, insurance, and equipment costs also climb. The lean case has the tightest cushion; the full case needs the steadiest backlog.

Planning assumptions only; these scenario figures are not guarantees.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean core crew	$292.5k	$87.8k	$147.5k	70%	$57.3k	Fits one core crew and early backlog, with a thin cushion above break-even.
Base retaining-wall and cofferdam mix	$770.2k	$214.2k	$228.0k	72.2%	$328.0k	Best fit for stronger demand and a wider cushion above break-even.
Full multi-crew operation	$1,319.8k	$337.8k	$327.5k	74.4%	$654.5k	Best fit for multi-crew use, but it needs steady backlog to keep the cushion.

What breaks the break-even plan for this sheet pile contractor?

Stress test

The base plan has a solid cushion, but it tightens fast if revenue drops, fixed overhead rises, or field costs creep up. The combined stress case leaves only about $62K of cushion, so crane idle time, barge standby, and permit delays are the real watchouts.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$1.92M	$1.00M cushion	Strong cushion at the base case.
Revenue slip	Monthly revenue falls 20% to $2.34M.	$1.92M	$419K cushion	A big job delay still clears break-even, but the buffer shrinks fast.
Fixed cost rise	Fixed overhead rises 10% to $1.48M.	$2.12M	$810K cushion	Yard rent, insurance, and bonding eat into profit.
Margin squeeze	Variable expense rate rises from 30% to 35%.	$2.07M	$856K cushion	Fuel, mobilization, and testing overruns push break-even up.
Combined pressure	Revenue falls 20%, variable expense rises to 35%, and fixed costs rise 10%.	$2.28M	$62K cushion	One delay can wipe out the cushion.

What should you verify before you lock in yard rent, crews, and heavy equipment for a sheet pile job?

Founder checklist

Don’t commit until the booked pipeline can carry about $187K a month in revenue, the Year 1 plan can really average $292.5K a month, and you have cash for the Month 6 trough of -$1.135M.

1Backlog cover$187K/mo

Verify signed and late-stage work can support this monthly run rate before you lock in yard rent and the first crew.

2Y1 burn$130.8K/mo

Check that yard rent, insurance, tools, office, bonding, and payroll stay inside this fixed burn, because they hit every month whether jobs slip or not.

3Margin mix70% CM

Hold the Year 1 cost stack near the model, with 30% tied up in steel, fuel, mobilization, and testing, or break-even moves higher fast.

4Crew load10 FTE

Confirm the opening crew can stay busy on booked hours before you add another crew, or payroll, standby, trucking, and supervision will outrun demand.

5Cash trough-$1.135M

Make sure opening cash or committed funding can absorb the Month 6 low, because the model still dips deeply negative before payback starts.

6Capex timingMonth 1-8

Stage the crawler crane, hammers, barge, trucks, and gear to booked work so one-time equipment spend does not crowd out operating break-even.
