Running Cost 1 : Specialized Payroll

Payroll Baseline

You must budget $87,083 per month for specialized payroll in 2026, covering your 9 core full-time employees. This includes the Principal Geotechnical Engineer earning $185,000 annually. This fixed monthly expense needs funding regardless of when your first project invoice pays out.

Calculating Staff Cost

Estimate this cost by multiplying headcount by target salaries plus employer burden (taxes, benefits). The $87,083 figure covers 9 FTEs for 2026. What this estimate hides is the cost of recruiting and the lag time before new hires become fully productive on site.

Need 9 FTEs budgeted for 2026.
Engineer salary is $185k/year.
Total monthly cost is $87,083.

Managing Staff Spend

Payroll is sticky; it doesn't flex down when project work slows. Avoid hiring ahead of secured contracts, especially for high-cost roles. If onboarding takes 14+ days, churn risk rises due to project delays. Keep the core team lean until revenue supports expansion.

Tie hiring to confirmed backlog.
Watch out for hidden benefit costs.
Delay non-essential roles.

Fixed Cost Pressure

This $87,083 monthly payroll is a heavy fixed operating expense. Compare this against your direct costs, like project energy consuming 140% of revenue in 2026. You need serious, high-margin project volume just to cover salaries and operating costs first.

Running Cost 2 : Facility & Yard Rent

Facility Overhead Fixed Cost

You need $15,000 monthly just for the yard and equipment maintenance space. This fixed cost is separate from your $6,000 headquarters office rent. Together, facility overhead totals $21,000 before any project starts. This baseline expense must be covered by project margins to achieve profitability.

Yard Cost Inputs

This $15,000 covers the yard and maintenance facility required for your specialized Artificial Ground Freezing (AGF) gear. It's a fixed cost, meaning it doesn't change with project volume. You must budget this $180,000 annually, separate from the $72,000 annual office rent. This space is critical for staging.

Covers specialized equipment staging.
Fixed at $15,000 monthly.
Annual cost: $180,000.

Managing Yard Commitments

Since this is fixed overhead, reducing it means negotiating lease terms or finding a cheaper location suitable for heavy equipment. Avoid signing multi-year commitments until you secure consistent project flow. A common mistake is locking in high rates before revenue stabilizes, especially when COGS are high.

Negotiate shorter initial leases.
Ensure yard supports heavy machinery.
Benchmark against local industrial rates.

Baseline Fixed Burn

Facility rent, combined with $8,500 for professional insurance and $87,083 for specialized payroll, sets your initial monthly burn rate high. You need sufficient project pipeline to cover these structural costs before tackling variable expenses like energy or drilling, which consume over 100% of revenue initially.

Running Cost 3 : Project Energy & Refrigerant

Energy Cost Crisis

Your energy and refrigerant costs are currently a huge drag. In 2026, these direct costs of goods sold (COGS) eat up 140% of project revenue. That means for every dollar earned, you spend $1.40 just on power and coolant. While this improves to 120% by 2030, you're losing money fast until then.

Energy Inputs

This line item covers the power needed to run the chillers and the cost of circulating the refrigerant fluid. To model this accurately, you need the projected energy draw (kW/h) per installed pipe segment multiplied by the local utility rate. Since it's 140% of revenue early on, it defintely dominates your initial negative cash flow.

Power draw for chiller units
Refrigerant fluid replacement costs
Pumping energy requirements

Cutting Power Waste

You must aggressively manage energy consumption per project hour. Since this cost is tied directly to operational time, focus on faster freezing cycles or better insulation around the pipes to reduce heat ingress. Avoid letting equipment run idle between phases. Anyway, the goal should be getting that 140% down to 100% within 18 months.

Negotiate industrial utility rates
Optimize insulation R-values
Minimize standby power usage

Profitability Hurdle

The fact that COGS exceeds revenue by 40% in 2026 means your pricing structure isn't viable yet, or your operational efficiency is too low. This cost category must drop below 100% quickly, otherwise, every job you win actively burns cash, regardless of how many clients you land.

Running Cost 4 : Subcontracted Drilling

Drilling Cost Shock

Outsourcing drilling is your biggest initial cost of goods sold (COGS). In 2026, this subcontractor expense consumes 100% of revenue. You need aggressive volume scaling or rate negotiation to bring this down to 80% by 2030. That's a tough starting margin, honestly.

Drilling Cost Inputs

This covers hiring specialized drillers to install the refrigerant pipes. Because this cost starts at 100% of revenue, your gross margin is effectively zero early on. You need firm quotes per linear foot drilled to model this against project scope.

Input: Quotes per linear foot.
Impact: Zero initial gross margin.
Context: Major COGS component.

Cutting Drilling Rates

You must drive the unit rate down faster than the projected 20% reduction by 2030. Negotiate volume tier pricing based on expected annual footage, not just single projects. Avoid relying on spot market pricing, which defintely kills early margins.

Target volume tier pricing.
Lock in rates early.
Minimize spot market use.

Total Direct Cost Pressure

Subcontracted drilling, combined with Project Energy costs (which are 140% of revenue in 2026), means your total direct costs far exceed revenue initially. You must achieve scale fast to cover these operational requirements before fixed overhead sinks you.

Running Cost 5 : Professional Insurance

Fixed Liability Cost

You must budget for specialized liability coverage as a baseline operating expense. This fixed cost of $8,500 monthly protects against errors in engineering design or execution related to ground stabilization, independent of project risk premiums. This cost is mandatory before securing the first contract.

Liability Cost Detail

This $8,500 covers Professional Liability Insurance, which protects against claims arising from faulty engineering advice or service errors, not physical damage. It's a fixed overhead, unlike variable project premiums. Budgeting this means setting aside $102,000 annually just for this baseline coverage.

Covers design/advice errors.
Fixed at $8,500/month.
Excludes project premiums.

Managing Fixed Risk

Since this is fixed, optimization focuses on minimizing the need for claims, not cutting the base premium. High-quality engineering documentation directly reduces potential liability exposure. If onboarding takes 14+ days, churn risk rises, increasing overall exposure time.

Focus on documentation quality.
Shop annual policies aggressively.
Ensure project premiums are clearly separated.

Risk Threshold Context

Never confuse this baseline fixed cost with variable project premiums that scale with contract size. If your initial fixed costs, including payroll ($87,083/mo) and facility rent ($21,000/mo total), push you too close to break-even, securing projects becomes a zero-sum game focused only on risk transfer.

Running Cost 6 : Marketing & CAC

Initial Marketing Load

You are budgeting $120,000 for marketing in 2026, accepting a high Customer Acquisition Cost (CAC) target of $15,000 per client. This spend directly dictates your initial client intake rate for securing specialized geotechnical contracts, meaning you can only afford about 8 new clients this first year.

CAC Budget Allocation

This $120,000 annual marketing line item funds lead generation aimed at landing large civil engineering firms. Based on the target $15,000 CAC, this budget supports acquiring only 8 new clients in 2026. You must track the actual cost per qualified bid versus the final contract win rate to validate this high acquisition price.

Annual spend target: $120,000.
Target cost per client: $15,000.
Implied annual clients: 8.

Lowering Acquisition Risk

A $15,000 CAC is high, but it's only sustainable if the project revenue is substantial. Focus marketing on high-probability targets, like repeat business with public transit authorities, rather than broad outreach. This spend is defintely high, so you must ensure client lifetime value (LTV) is at least three times the CAC to maintain margin.

Prioritize repeat clients.
Target known infrastructure needs.
Ensure LTV significantly exceeds CAC.

CAC Threshold Check

If your average project revenue doesn't immediately support a $15,000 upfront cost, you must lower the CAC or secure much larger initial contracts. This marketing commitment is fixed until you prove otherwise through successful contract execution.

Running Cost 7 : Site Logistics

Logistics Cost Drag

Site Mobilization and Logistics costs are currently too high, eating up 50% of revenue in 2026. Your primary operational goal must be aggressive optimization to pull this variable expense down to 42% by 2030. That 8-point reduction is where margin gets built, defintely.

Logistics Scope

This category covers moving specialized equipment, temporary site setup, and demobilization after the freezing process ends. It scales directly with project volume and complexity. For 2026, this 50% slice of revenue is a major drain, meaning every dollar earned must cover $0.50 just for site movement.

Distance to job site.
Required heavy equipment count.
Duration of site presence.

Cutting Logistics Drag

Reducing Site Logistics from 50% to 42% requires standardizing mobilization kits and negotiating fixed rates with transport vendors. You can't eliminate this cost; it's tied to physical work. Focus on increasing project density within geographic zones to reduce travel frequency.

Standardize equipment staging areas.
Negotiate multi-year transport contracts.
Improve project scheduling accuracy.

Margin Impact

Hitting the 42% target by 2030 frees up 8% of revenue, which is critical margin. Given that Project Energy is 120% of revenue in 2030, this logistics saving is the only way to offset direct COGS pressure and achieve profitability.
