Prevailing wages (government minimums)

- Wage:
- the hourly pay in the worker's paycheck, before taxes, at straight time.
- Overtime and double time:
- the wage × 1.5 and × 2. Federal contracts require time and a half after 40 hours a week; when double time applies (for example Sundays, holidays or after 10–12 hours) is set by each union contract.
- Benefits:
- paid by the employer on top of the wage into the worker's health insurance, pension and annuity, and apprenticeship training funds (sometimes vacation and holiday pay). Not in the paycheck.
- Total comp:
- wage + benefits for one straight-time hour.
Journeyman rates only; shift premiums and per diem are not included. Source: Davis-Bacon general wage determinations on SAM.gov.
Apprentices: rates above are for journeymen. Apprentices are usually paid a percentage of the journeyman rate, typically starting around 40–60% and rising about 10 percentage points every 6 months to a year until they reach the full rate. Exact steps vary by trade and local.
