General Conditions Cost Management: The Overhead You're Probably Underestimating

General conditions (GC's) — the project-specific overhead of running a jobsite — typically runs 6-12% of direct construction cost on commercial projects. It includes site trailer, superintendent, safety manager, temporary utilities, cleanup, security, project engineer, and dozens of other line items. Contractors who estimate general conditions casually regularly get surprised by real cost at project end. Systematic general conditions estimating and management produces better bids and fewer project-end surprises.
