Certified payroll for concrete subs (C-8) in California
What certified payroll actually looks like in the concrete trade on California public works, plus live registration activity for the classification.
Data updated 2026-09-19
The concrete trade's certified payroll reality
Concrete work touches more crafts per square foot than any other trade on a public job: cement masons on placement and finish, laborers on prep and cleanup, carpenters on formwork, ironworkers on reinforcing steel where your scope includes it, and operators on the pump. Five crafts, five rate lines, one certified payroll. Overtime discipline matters doubly, since pours run long by nature and daily overtime multipliers in the determinations apply on top of the base split. Site work also puts concrete subs on Caltrans and city street projects, where the legacy compliance program rules change what gets filed where: check the awarding body before assuming the standard DIR path.
Whatever the craft mix, the mechanics are the same statewide: rates come from the project county's published determination (DIR lookup), the eCPR goes directly to DIR on non-exempt projects, and the federal WH-347 rides along weekly where federal funds apply. The full picture is in the complete guide.
