Change order audit for general contractors

Direct answer

How do general contractors audit change-order leakage?

Audit change-order leakage by reconciling field directions and daily records against the change log, approval status, job-cost ledger, pay applications, invoices, and cash received. The leakage is any authorized or performed extra work that was never priced, submitted, approved, billed, or collected—or a cost incurred without a recoverable change path.

Operational completeness check

Field-to-log completeness

Every directive, RFI cost effect, daily ticket, and revised drawing has a change-event record.

Cost capture

Labor, material, equipment, and subcontract commitments are assigned to the correct change event.

Status aging

Requested, priced, submitted, revised, approved, rejected, billed, and paid dates are distinct.

Billing reconciliation

Approved changes reach the contract value, SOV, pay application, invoice, and receivables ledger.

Root cause

Each leak is assigned to late notice, missing backup, unclear authority, pricing delay, or billing handoff.

This is a process-control audit. Disputed entitlement, notice compliance, or contract interpretation should be reviewed by qualified project and legal advisers.

Every GC has a version of the same exposure: change orders that got a verbal yes in the field and never made it into writing before the work happened. Reviewing the documentation before a dispute forces the issue is the only time it's cheap to fix.

“Under field conditions, where issues arise unexpectedly, approval is often verbal, and there is pressure to remain on schedule. Contractors and subs often proceed without first securing written authorization from the owner.”

“I am running two jobs at the same time and STILL authorizing subcontractor work and material purchases the same way I was on that job.”
