How Do I Verify Milestone Completion before Releasing the Corresponding Payment?

Treat the milestone schedule in the contract as the binding guide. Before each payment, arrange a third‑party inspection that matches the written drawings and permits, and obtain a formal inspection report. Compare the site progress with the contract drawings, and record any defects in a dated log with agreed deadlines for rectification. Require the contractor to supply as‑built drawings, warranties and supplier manuals before final payment. Keep back a portion of the payment until all punch-list items are completed to a satisfactory standard. Include remedies for late completion or missed milestones, and specify how change orders will be handled in writing. Only release funds when the certificates, photos or reports confirm completion; avoid verbal assurances. Finally, ensure the handover package (permits, warranties, manuals, access keys, and as‑built drawings) is all in one package before the last payment.
