Which pipeline construction and maintenance expenses are fixed, and which move with sales?

Cost classification

Break-even is only useful if fixed overhead and revenue-linked expenses are separated cleanly. In this model, Month 5 break-even depends on not treating payroll, fleet, and yard costs like they vanish when jobs slow.

Expense	Cost	Break-Even Treatment	Common Mistake
Office & Yard Rent	Fixed	Count $5,000 per month in fixed overhead for the active planning range.	Spreading rent across projects and hiding idle-month cash burn.
General Business Insurance	Fixed	Count $1,500 per month as fixed overhead, separate from project-specific coverage.	Blending company insurance into job margin and double-counting coverage.
Project Materials & Consumables	Variable	Apply 13.0% of revenue in the first year, declining to 9.0% by the fifth year.	Using a flat dollar estimate when job size changes.
Direct Project Labor & Subcontractors	Variable	Apply 9.0% of revenue in the first year, declining to 7.0% by the fifth year.	Mixing subcontractor spend with salaried payroll that still runs.
Project-Specific Insurance & Permits	Variable	Apply 2.5% of revenue in the first year, declining to 1.5% by the fifth year.	Treating permit and job policy charges as fixed office overhead.
Project Site Mobilization & Logistics	Semi-variable	Model the revenue-linked portion at 3.5% in the first year, with dispatch minimums tracked separately.	Assuming every mobilization dollar disappears when revenue pauses.
Core Salaried Team	Semi-fixed	Count founder, engineer, technician, business development, operations, and admin salaries by FTE step.	Treating idle crews as variable when payroll still runs.
Vehicle Fleet Lease & Maintenance	Semi-fixed	Count $3,000 per month while fleet capacity is stable; step it up when more units are added.	Modeling the full fleet line like per-job fuel.

How does break-even shift from lean to full pipeline contractor scale?

Scenario table

As fixed overhead rises from $63.4k to $118.8k and variable costs fall from 28% to 20%, break-even revenue climbs, but the profit cushion widens with scale.

Planning case only: these are model assumptions, not guaranteed results.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch mix	$134k	$37.5k	$63.4k	72%	$33k	Near break-even; a small backlog slip can wipe out profit.
Base contractor scale	$569k	$136.6k	$92.1k	76%	$340k	Clear cushion; steady crew use covers overhead and lifts profit.
Full-scale contractor platform	$1.24M	$248k	$118.8k	80%	$873k	Strong cushion; scale only works if backlog and crews stay full.

What breaks the break-even plan for pipeline construction and maintenance?

Stress test

The main break-even risk is timing: a 20% revenue slip cuts cushion to about $139k, and field-cost or overhead creep can erase the rest. Under combined pressure, the plan is only about $42k from a monthly loss.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$881k	$332k cushion	Base plan still clears overhead.
Revenue shortfall	Monthly revenue falls 20%.	$881k	$139k cushion	Slower billing cuts the buffer fast.
Fixed-cost pressure	Fixed overhead rises 15%.	$1,013k	$237k cushion	Headcount and fleet creep eat margin.
Margin pressure	Variable expenses rise from 28% to 36%.	$991k	$225k cushion	Fuel and subcontractor costs squeeze contribution.
Combined pressure	Revenue falls 20%, variable expenses hit 36%, and fixed costs rise 15%.	$1,139k	$42k gap	The plan slips into a monthly loss.

Should you lock the yard lease and heavy equipment before signed work proves break-even?

Founder checklist

Don’t lock the yard lease or buy heavy gear until signed work covers the $13.8K monthly fixed load and the Month 6 cash low of -$113K. Break-even shows up in Month 5, but cash still has to make it through the ramp.

1Backlog cover$55.2K

Use the Year 1 blend — 40 integrity hours at $180, 120 construction hours at $220, 80 repair hours at $200, and 20 emergency hours at $280 — to prove the first work pack is real before you treat the pipeline as covered.

2Lease load$13.8K/mo

Treat the $5,000 yard lease as a hard gate, because fixed overhead is $13.8K a month and should be covered by signed work, not a verbal backlog.

3Contribution margin72% CM

Keep the project cost stack near 28% of revenue so contribution stays around 72%, or the Month 5 break-even target gets pushed back.

4Crew ramp$545K

Hold core hiring to the booked hours you can actually run, because the Year 1 salary load is about $545K and extra FTEs will eat cash before the work lands.

5Cash trough-$113K

Buy or finance the big equipment only if the cash plan still survives the Month 6 low of -$113K after the $450K excavator and other capex hit.

6Receivable timingMonth 5

Line up receivables funding now, because break-even lands in Month 5 but cash still bottoms out in Month 6, so paper profit won't pay vendors fast enough.
