Let's run a real example. A $200K mid-size excavator used 150 days/year at a daily rental rate of $900.
| Cost Component | Buy | Rent (150 days/yr) |
|---|---|---|
| Year 1 out-of-pocket (down + payments or rental) | $40K down + $36K payments = $76K | $135K rental |
| Annual ownership cost (yrs 2–5) | $36K payments + $8K maint + $4K ins = $48K/yr | $135K/yr rental |
| 5-year total cost | ~$268K (+ residual value ~$80K) | ~$675K rental |
| Net 5-year advantage | Buy wins by ~$327K | — |
At 150 billable days/year, buying wins significantly. At 60 days/year, the math flips — ownership costs exceed rental at that utilization level. The utilization assumption is everything. Run it honestly before you sign the loan documents.
It depends on utilization rate. If equipment will be used 60%+ of the time on billable jobs, buying typically wins over 3–5 years. Below 40% utilization, renting is almost always cheaper when you factor in depreciation, insurance, maintenance, financing, and idle time.
An internal equipment rate is the cost per hour or day assigned to owned equipment when used on a job. It covers depreciation, maintenance reserve, insurance, and financing. Without it, equipment costs disappear into overhead — and job margins look better than they actually are.
A financed equipment purchase requires 10–20% down plus monthly payments. The down payment is an immediate cash event — $50K–$150K for most commercial equipment. If the equipment isn't generating enough utilization to offset ownership costs, it becomes a cash and margin drain.
Set an internal equipment rate — a daily or hourly charge per machine. When equipment works a job, the job gets charged at that rate. SPM builds this into ControlQore so equipment costs flow to jobs automatically and overhead allocation stays accurate.

| Cost Component | 3-Week Impact | Recoverable? |
|---|---|---|
| Idle crew (10 people × $4,500/day all-in × 15 days) | ~$67,500 | Yes — with daily log and written notice |
| Extended supervision and project management | ~$12,000 | Yes — with documented general conditions |
| Equipment standby (lifts, conduit benders) | ~$8,500 | Yes — with equipment logs |
| Delayed billing (1 pay app cycle = 30 days at 60-day terms) | ~$80K–$150K cash gap | No — structural delay in cash receipt |
| Retainage extension (1 month × 10% on $2M job) | ~$20,000/month | No — retainage releases at project close |
The recoverable costs require a daily delay log and formal GC notification. If you don't have the log, you don't have the claim. SPM helps clients build the financial documentation discipline that makes delay cost recovery possible — not as a legal strategy, but as a standard part of how the job is managed financially.
MEP coordination delays stop installation — and installation drives billing. If crews are waiting for coordination models to resolve, your billed percentage falls behind your cost percentage — creating an underbilling gap that tightens cash flow exactly when costs keep accumulating.
Sometimes, but it requires daily documentation and formal GC notice from Day 1. Delay costs — idle crew time, extended supervision, equipment standby — need to be tracked daily. If you can't show contemporaneous records, the GC has no obligation to pay them.
On a $1.5M MEP sub with a 10-person crew at $4,500/day all-in, a 3-week full-stop delay costs roughly $88K in potentially recoverable crew and equipment costs — plus a 30-day billing delay that creates another $80K–$150K cash gap from the pay-when-paid cycle.
Daily. Start a formal delay log the day the delay begins: date, cause, scope stopped, crew hours, equipment standby, and written GC notification sent same day. Courts and arbitrators consistently side with subs who maintained contemporaneous daily records over those who reconstructed them later.
One call. We'll show you how to forecast around delays — and document the costs that are yours to recover.
