Subcontractor Onboarding: Why Compliance Starts Before the First Day of Work
Non-compliant subcontractors are the leading cause of certified payroll deficiencies and audit findings on federal projects. A structured pre-construction onboarding process eliminates most compliance gaps before they start.

Why Subcontractor Compliance Failures Are So Common
On most federally funded construction projects, the general contractor is responsible for the compliance of every subcontractor on the project — not just their own workforce. A subcontractor that misclassifies workers, submits late or inaccurate certified payroll, or fails to document Section 3 participation creates a compliance deficiency that the GC must resolve, often at significant cost and delay.
The root cause of most subcontractor compliance failures is not bad intent — it is lack of preparation. Subcontractors who have not worked on federal projects before are often unaware of the specific requirements, the weekly reporting deadlines, and the consequences of non-compliance. A structured onboarding process addresses this before work begins.
What a Compliance Onboarding Package Should Include
Every subcontractor should receive a written compliance onboarding package before mobilizing. This package should include: a copy of the applicable wage determination with the relevant trade classifications highlighted, a summary of certified payroll requirements and submission deadlines, login credentials and setup instructions for the compliance platform (Elation, LCPtracker, or B2Gnow), Section 3 worker self-certification forms, MWBE certification verification requirements, and contact information for the compliance consultant or GC compliance coordinator.
Do not assume that a subcontractor who has worked on federal projects before is familiar with your specific platform or agency requirements. Requirements vary significantly between HUD, GLO, TDHCA, and City projects.
The Pre-Mobilization Compliance Meeting
Before any subcontractor begins work, conduct a pre-mobilization compliance meeting — either in person or by video call. Walk through the certified payroll requirements, the weekly submission deadline, the classification requirements for the work that subcontractor will perform, and the consequences of late or deficient submissions.
Document that the meeting occurred, who attended, and what was covered. This documentation protects the GC if a subcontractor later claims they were not informed of the requirements. It also establishes a direct line of communication between the subcontractor's payroll contact and your compliance team.
Setting Up Workers in the Compliance Platform
One of the most time-consuming parts of subcontractor onboarding is getting workers set up correctly in the compliance platform before the first week of work. Each worker must be entered with their correct name, Social Security number (or last four digits, depending on the platform), trade classification, and wage rate.
Errors in worker setup — particularly classification errors — propagate through every subsequent certified payroll submission and can require retroactive corrections across multiple pay periods. Require subcontractors to submit their worker roster for review before mobilizing, and verify that each worker's classification matches the work they will perform.
Ongoing Monitoring After Onboarding
Onboarding is the beginning of compliance management, not the end. Establish a weekly review process for each subcontractor's certified payroll submissions. Review for completeness, classification accuracy, wage rate compliance, and fringe benefit calculations. Flag deficiencies immediately and require correction within the same week.
Track each subcontractor's submission history throughout the project. A subcontractor that consistently submits late or with errors is a compliance risk that needs to be addressed directly — either through additional training, more frequent check-ins, or in serious cases, escalation to the funding agency.
