Construction Payroll every rate, every job.
Construction payroll for contractors who pay different rates on different jobs, bid public works, and need labor coded to every project.
Construction payroll is rarely one rate per person. A carpenter may earn a private-job rate on Monday and a prevailing wage rate on Tuesday, with fringes, overtime, and workers' comp classes that change with the work. California public works projects require contractor registration with the Department of Industrial Relations, prevailing wage rates by craft and county, and certified payroll records. Federally funded projects can add Davis-Bacon requirements. TreeStar processes payroll by job and classification, helps prepare certified payroll reports, tracks union or benefit fringe contributions, and keeps the records your workers' comp premium audit will ask for.
Where it gets complicated
- 01 Multiple rates per week
One employee can work at several rates in a single week. Overtime has to be calculated correctly across all of them, and an error repeats every pay period.
- 02 Certified payroll deadlines
California public works call for certified payroll records submitted to the Department of Industrial Relations, and federal projects have their own forms. Late or inaccurate reports can hold up payment and bring penalties.
- 03 Prevailing wage and fringes
Prevailing wage includes a base rate and a fringe amount, which can be paid in cash, into benefit plans, or a mix. Documenting how each hour's fringe was satisfied is a common audit question.
- 04 Union fringe reporting
Union contractors send monthly reports and contributions to several trust funds. Hours have to agree with payroll, or a trust fund audit may find the gap.
- 05 Workers' comp classes
Premiums are based on payroll by job classification. Hours left in the wrong class can raise your premium at the annual audit.
