Section 5— Payment

Clause 51.2

Payment Certificates — Interim

Purpose

The PM issues interim payment certificates at each assessment date until the Defects Certificate is issued. Each certificate covers the period since the last certificate.

Practical Application

Interim certificates provide regular cash flow. The Contractor submits an application before each assessment date showing the value of work done.

Common Pitfalls

If the Contractor does not submit a timely application, the PM assesses based on available information, which may understate the amount due.
