Frequently asked questions

What is the difference between a lump sum and unit price contract for heavy civil projects?

A lump sum contract sets a fixed total price for the entire project, while a unit price contract pays based on measured quantities of work (e.g., per cubic yard of excavation). Unit price is common in heavy civil when quantities are uncertain.

Do I need a performance bond for a heavy civil construction contract?

Often yes, especially for public projects. Many government agencies require performance and payment bonds to protect against contractor default. Private owners may also request them for large projects.

What are retainage and how does it work?

Retainage is a percentage (typically 5-10%) withheld from each progress payment until project completion. It protects the owner against defects or unfinished work. The contract should specify the percentage and conditions for release.
