OVERTIME COST

OVERTIME COST IN JOB COSTING.

QUICK ANSWER

Overtime is the most expensive labor decision in construction, and the one made most often without a clear picture of the true cost. The premium on the base wage is 50 percent, time and a half, but in most cases the burden is calculated on the full overtime rate rather than on the base. True overtime cost per hour can run 1.6 to 1.8 times the regular fully loaded hour depending on your burden structure.

The decision gets made on the schedule, not on the money. A job slips two weeks, the foreman asks for Saturdays, and the yes takes about ten seconds because nobody in that conversation can say what a Saturday costs. Then the job closes light and the labor overrun gets blamed on production. Overtime coded as regular labor is invisible by design, so the same call gets made again on the next job. Code it on its own and the second call comes with a figure attached to it.

THE DEFINITION

WHAT IT MEANS.

Overtime cost in job costing is the premium wage plus the burden charged on that premium, coded to the job that consumed the hours instead of buried inside one labor total.

Overtime gets authorized for three different reasons, and the three carry very different money. A GC directing acceleration is billable work. Schedule recovery on your own production problem comes straight out of margin. Weather sits between the two and depends on what the contract says. If all three post to the same labor code, the billable hours never get billed.

WHAT WE SEE IN THIS BUSINESS

WHERE THE PREMIUM DISAPPEARS.

01

You're using overtime to fix schedule problems without seeing the true cost

When a project falls behind, the instinct is to authorize overtime. The foreman says the crew needs it, the GC wants the milestone, and the hours get approved that afternoon. Most contractors have no clear picture of what that decision cost the job, because the system doesn't separate the overtime premium and the burden riding on it from regular labor.

02

Overtime burden is higher than you think

The premium on the overtime base wage is 50 percent, time and a half, and most contractors stop the math right there. In most cases the burden cost on overtime hours is calculated on the full overtime rate and not on the base wage, so the burden climbs with the premium. True overtime cost per hour can run 1.6 to 1.8 times the regular fully loaded hour depending on your burden structure.

03

You're not seeing overtime cost by job

If overtime cost isn't coded separately in job costing, you can't see which jobs are consuming it, whether a GC change order authorized it, or whether job conditions make it a recoverable claim. The hours sit inside total labor, so the only signal you get is a labor overrun at closeout. By then the documentation that would have supported a claim doesn't exist.

THE ARITHMETIC

WHAT IT LOOKS LIKE IN DOLLARS.

The premium and the burden on it

Time and a half puts the wage at 1.5 times base, and that's where most estimates stop. The burden riding on those hours is usually calculated on the full overtime rate, which is why a loaded overtime hour comes in at 1.6 to 1.8 times a regular loaded hour. The distance between the 1.5 everybody assumes and the 1.6 to 1.8 they're paying is the part no bid carries.

HOW SPM FIXES IT

HOW THE HOURS GET CODED AND PRICED.

Overtime as a separate cost code in job costing

SPM sets up overtime as a separate labor cost code in ControlQore, distinct from regular labor, so every job's overtime cost is visible on its own. You can compare it against what the estimate carried and against what somebody authorized. A cost in its own column is a cost somebody can question before the job closes out.

True overtime cost calculation

SPM builds true overtime cost rates into the ControlQore labor rate structure, accounting for the premium wage rate and the burden charged on that premium rate. The rate you approve overtime against is the loaded rate, not the base wage times 1.5. That's the difference between an approval and a guess.

Authorized against unauthorized overtime tracking

SPM tracks overtime cost by authorization source, whether GC directed, schedule recovery, or weather related, so the documentation supporting a change order claim exists at the time the hours are worked. Contemporaneous records are what a GC accepts and what a reviewer won't argue with. Records rebuilt six months later are what claims die on.

COMMON QUESTIONS

FREQUENTLY ASKED.

It makes sense when the overtime cost comes in under the cost of the delay, when it's recoverable from the GC, or when an early completion bonus covers it. It's rarely justified as a routine productivity tool, because the true cost per hour almost always exceeds what a night crew or an added crew would cost for the same output. The test is worth running each time, because the answer changes with the job and with who caused the delay.
Yes, if the delay was GC caused and the contract permits acceleration recovery. It requires contemporaneous documentation of the delay, the authorized overtime, and the cost. SPM tracks overtime by job and by authorization source, so that record is built while the work is happening rather than reconstructed from memory when the claim goes in.
