SUPERVISION COST IS HIDING IN YOUR OVERHEAD.
Foreman, superintendent, and project coordinator labor is project-specific cost — not overhead. When it lands in overhead, it inflates your overhead rate, understates your true direct job cost, and makes every estimate less accurate. Contractors who correctly allocate supervision as a direct job expense bid more accurately, track real margins, and recover supervision costs from GCs through change orders instead of absorbing them.
Most subcontractors lump supervision into overhead because it's easier. The foreman doesn't install conduit — he supervises the crew. He doesn't pour concrete — he manages the pour. So the thinking goes: he's not "direct labor," he goes to overhead. That's wrong. And it's costing you money on every estimate and every job.
WHY SUPERVISION IN OVERHEAD BREAKS YOUR NUMBERS.
Here's what happens when a superintendent making $95,000/year goes into overhead. Your overhead rate goes up — let's say it was 12% and now it's 15%. You apply that 15% to every job uniformly. A small, fast job and a large, superintendent-intensive job both get charged the same overhead percentage. But the large job actually consumed 80% of that superintendent's time. The small job consumed 5%. You're over-recovering supervision cost on the small job and under-recovering it on the large one. Your estimates are wrong before you submit them.
Now multiply that across a foreman ($75,000), a project coordinator ($60,000), and a safety officer ($70,000). You have $300,000 in supervision labor sitting in overhead, getting spread as a percentage across all jobs regardless of which jobs actually used those people. The jobs that needed heavy supervision look more profitable than they are. The jobs that ran lean look less profitable. You can't see which jobs are actually making money — because the biggest variable cost after direct labor is allocated wrong.
There's a second problem: change orders. If a GC-directed scope change requires two additional weeks of superintendent time, and supervision isn't in your direct job expense cost codes, you have no billing basis for it. The cost exists. The billing vehicle doesn't. It gets absorbed because it was never tracked as a job cost to begin with.
The correct category: Foreman, superintendent, project manager, assistant PM, project coordinator, safety officer, and job-site admin all belong in Direct Job Expense — allocated to the specific jobs they support, tracked against the hours and cost budgeted in the estimate. Only truly company-wide supervision (owner salary, executive PM oversight of all jobs) belongs in overhead.
HOW SUPERVISION COST GETS MISCLASSIFIED.
FOREMAN TIME LUMPED INTO CREW LABOR AT INSTALL RATE
The foreman runs the crew. He also does timecards, attends coordination meetings, manages material deliveries, and handles the daily GC interactions. That non-productive time is real labor cost that isn't producing installed work. When foreman hours are lumped into install labor at the same burden rate as the crew, two things go wrong: the install labor productivity looks worse than it is (foreman hours dilute the install rate), and the supervision cost isn't visible as its own line item. A foreman running a 5-person crew at $72/hour fully burdened, spending 30% of his time on supervision functions, represents $43,200/year in supervision cost that's invisible in the labor report. It needs its own cost code and its own budget line in the estimate.
SUPERINTENDENT SALARY GOING ENTIRELY TO OVERHEAD
A superintendent who manages 3 to 5 active jobs simultaneously is a direct cost to each of those jobs — allocated by time and job size. Putting their full salary in overhead treats them as a fixed company cost, like rent. They're not. Their time, fully burdened, is $8,000–$12,000 per month. On a job where they're on-site 60% of the time, $4,800–$7,200 per month belongs in that job's direct job expense — not spread across all jobs as overhead. This change alone corrects estimated overhead rate by 2–4 percentage points on a typical $4M subcontractor, making every subsequent estimate more accurate.
PROJECT COORDINATOR COST INVISIBLE IN ESTIMATES
Submittals, RFIs, change order documentation, scheduling, procurement coordination — this work is done by a project coordinator or assistant PM and it's entirely job-specific. Most estimators don't budget for it because it's always been in overhead. But on a $1.5M job that runs 9 months, a coordinator spending 25% of their time on that job represents $14,000–$18,000 in direct cost that should be in the estimate under Direct Job Expense. When it's not, you win the job at a price that doesn't recover coordination cost. You can't cut the coordinator — the job needs them. You just didn't price it in.
HOW TO ALLOCATE SUPERVISION ACCURATELY.
WHAT WRONG SUPERVISION ALLOCATION COSTS YOU.
Overhead Rate Is Overstated by 3–6%
A $5M contractor with $300K in supervision in overhead is running a 6% supervision-inflated overhead rate. Removing it and allocating correctly drops overhead to its real level — and makes every bid 3–6% more price-competitive without reducing actual profit.
Supervision-Heavy Jobs Look Less Profitable Than They Are
A job that needed heavy superintendent involvement gets charged average overhead — not the actual supervision cost it consumed. The job looks like it underperformed. The real problem is the cost structure, not the job execution.
GC-Directed Supervision Changes Go Unbilled
Without supervision as a direct job expense line, there's no cost code basis for billing extra superintendent or coordinator time when the GC changes the sequence, delays the schedule, or adds coordination requirements. That cost gets absorbed — every time.
