Section 5— Payment

Clause 51.4

Payment Certificates — Correction

Purpose

The PM may correct any certificate in a later certificate. The correction applies retrospectively.

Practical Application

The PM may adjust an earlier certificate if new information emerges or an error is discovered. The adjustment is made in the next certificate.

Common Pitfalls

Late corrections can disrupt cash flow. The Contractor should track cumulative amounts paid versus expected to detect corrections disguised in later certificates.
