Become a Subcontractor on SCDOT Projects

SCDOT’s contract is typically with the prime contractor not the subcontractor.
Working as a subcontractor requires less interaction with SCDOT, however, there are still opportunities for interaction. SCDOT’s goal is to provide quick access to the following forms and resources:

Step 1 – Find SCDOT Projects that need your services

SCDOT doesn’t deal directly with subcontractors on projects, but there are a number of resources that you can use to find upcoming projects that need your services.
