How to use the construction labor cost calculator
Construction labor cost is built the same way everywhere: multiply the work quantity by the labor-hours it takes to install one unit, then multiply by the hourly cost of the crew. This calculator splits the crew into a skilled trade and a laborer so you can price a single work item the way an estimate line is actually assembled.
The mechanism behind the numbers differs from country to country. Korea uses a government-published productivity standard and a semiannual survey of trade wage rates that public agencies must apply. The United States has no equivalent official standard: productivity comes from commercial data books such as RSMeans or from in-house historical records, and wage floors on public work come from Davis-Bacon prevailing wage determinations rather than a national schedule.
Because a Davis-Bacon determination lists a base rate and a fringe benefit rate separately, both fields are provided here. The productivity adjustment covers night work, restricted access, high work and small quantities where a crew cannot reach normal output.
The output is direct labor cost only. Payroll burden, field and general overhead, and profit are layered on top before a bid number is reached, and prevailing wage compliance should be confirmed against the current wage determination for the project county before the estimate is finalized.
Frequently asked questions
There is no government-issued productivity standard in the United States. Estimators rely on commercial cost databases such as RSMeans, which publish a daily output and labor-hours figure for each crew and work item, or on the contractor own historical production records for similar work.
On federally funded work the Davis-Bacon Act requires contractors to pay the prevailing wage determination for the county and trade, and that determination lists a base hourly rate plus a separate fringe benefit amount. Both parts count toward the required rate, so estimates need them as distinct line items.
No. The result is bare labor cost including fringes only. Payroll taxes, workers compensation, general liability, field overhead and profit are added separately, which is why a fully burdened billing rate is typically far higher than the wage plus fringe figure.
