Frequently asked questions

Why do I need a subcontractor agreement specific to heavy civil construction?

Heavy civil projects involve unique risks like site safety, environmental compliance, and public works regulations. A tailored agreement addresses these issues and ensures your subcontractor understands their responsibilities, reducing the risk of disputes and project delays.

What is a flow-down clause and why is it important?

A flow-down clause makes the subcontract subject to all terms of the prime contract between you and the owner. This ensures that the subcontractor is bound by the same obligations, including specifications, schedules, and dispute resolution, which is critical for maintaining consistency and avoiding conflicts.

How does retainage work in this agreement?

Retainage is a percentage (typically 5-10%) withheld from each progress payment until the work is completed and accepted. This protects the prime contractor against defects or incomplete work. The agreement specifies the retainage percentage and conditions for release.
