Which soil stabilization expenses are fixed, and which move with sales?

Cost classification

Break-even is only useful if fixed overhead stays fixed and field costs move with work. In the first operating year, fixed rent and insurance alone are $22,700/month, while materials, mobilization, labor, and compliance rise with job volume.

Expense	Cost	Break-Even Treatment	Common Mistake
Equipment Yard Lease	Fixed	Include in monthly overhead at $12,000 from Month 1 through Month 60.	Waiting for backlog after signing the lease.
Technical Office Rent	Fixed	Include in monthly overhead at $6,500 from Month 1 through Month 60.	Treating office rent as project-driven.
Professional Liability Insurance	Fixed	Include in monthly overhead at $4,200 from Month 1 through Month 60.	Leaving insurance out of break-even.
Chemical Grout Material and Cementitious Binders	Variable	Tie directly to job volume: $4,200 per chemical grouting project and $350 per jet grouting column.	Using one blended material rate across different scopes.
Direct Field Labor and Operator Wages	Semi-variable	Flex with crew days: $2,500 per chemical grouting project and $220 per jet grouting column.	Assuming labor falls to zero when jobs pause.
Equipment Maintenance Fund and Drill Rig Maintenance	Semi-fixed	Model as use-linked overhead at 1.5% and 1.2% of revenue, sitting above direct job inputs.	Pricing only fuel and ignoring maintenance load.
Site Mobilization Logistics	Variable	Use 4.5% of first-year revenue, equal to about $150,750 on $3.350 million of revenue.	Underbidding haul time and setup moves.
Safety Oversight and Environmental Monitoring	Semi-variable	Increase with field activity at 0.6% and 0.4% of revenue, especially on active sites.	Cutting compliance to protect margin.

How does break-even change from a lean launch case to base and full utilization?

Scenario table

The lean case is the launch gate: revenue just covers project costs and fixed overhead. The base case adds real cushion, while the full case tests how much profit stays left when the crew runs near capacity.

Planning assumptions, not guarantees; hiring, equipment, and yard changes can move break-even.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch gate	$121k	$39k	$82k	67.8%	$0	Use this as the go/no-go floor.
Year 1 base plan	$279k	$90k	$82k	67.7%	$107k	Solid first-year cushion if labor stays stable.
Full-utilization capacity case	$409k	$132k	$82k	67.7%	$195k	Good scale case, but overhead can rise fast.

What pushes this soil stabilization plan close to break-even?

Stress test

Base case is above break-even, but the cushion shrinks fast if project starts slip, mobilization runs hot, or fuel and binder costs rise. A 25% revenue dip, 15% overhead jump, or 10-point margin hit still leaves profit, just less.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change to revenue, fixed overhead, or margin.	$121k/month	$158k cushion	There is room, but launch timing still matters.
Revenue shortfall	Revenue comes in 25% below plan.	$121k/month	$88k cushion	A sales miss trims the cushion fast, even before costs move.
Fixed-cost increase	Fixed overhead rises 15%.	$139k/month	$140k cushion	Lease, rent, insurance, and admin creep push the line up.
Margin pressure	Contribution margin falls 10 points from plan.	$142k/month	$137k cushion	Fuel, binder, and rework pressure can move break-even fast.
Combined pressure	Revenue is down 25%, fixed overhead is up 15%, and margin is down 10 points.	$163k/month	$46k cushion	Slow starts plus cost creep can burn most of the cushion.

What should you verify before buying the rig and signing the yard lease for this soil stabilization service?

Founder checklist

Before you commit, prove the backlog can support the $1.12M equipment build and the $18.5K monthly lease pair. The model breaks even by Month 2, but the real test is whether your Year 1 mix, staffing plan, and $810K cash buffer hold through Month 6.

1Backlog Proof$1.12M

Verify signed work can justify the rig, pump, lab, trailer, racking, and workstation spend before you buy.

2Fixed Load$18.5K/mo

Do not sign the $12K yard lease and $6.5K office rent until booked work can carry that monthly drag.

3Year 1 Mix12/450/8/15/60

Check that the first-year mix of 12 chemical projects, 450 jet columns, 8 deep soil mixing sites, 15 compaction projects, and 60 soil reports is real, because that is the launch demand the model assumes.

4Margin Check71%-78%

Contribution margin is what is left after direct costs and variable selling costs, so keep the early mix near 71% to 78% and reprice grout, binders, fuel, nozzles, and lab fees if it slips.

5Staffing Ramp$637.5K/yr

Keep launch payroll near $637.5K a year and 5.5 FTE, or hiring will outrun booked jobs.

6Cash Cushion$810K

Hold at least $810K of cash at the Month 6 low point and lock safety, insurance, testing, permits, mobilization routing, and subcontractor coverage before ramp-up spend.
