Budget overruns fall into two categories: scope changes (client-initiated, field-discovered conditions, or code-required work) and estimating errors (items omitted or incorrectly priced in the original estimate). Scope changes are documented as change orders — every dollar of added scope is written and signed before work proceeds. Estimating errors are RainFire Builders’ responsibility and are absorbed, not billed to the client. This distinction is defined in the contract, the project’s cost history is tracked transparently in monthly job cost reports, and the client always knows the current authorized contract value and the reason for any change from the original.
