A payment certificate refers to a document issued by a Quantity Surveyor that authorizes payment to a contractor for the work completed during a specific period, based on the terms and conditions outlined in the construction contract. The payment certificate is typically generated after evaluating the progress of the construction work, verifying the accuracy of the contractor’s payment application, and confirming compliance with the contract specifications.

The quantity surveyor assesses the amount of work completed, the materials used, and any other costs incurred by the contractor. The payment certificate then reflects the value of the work done, taking into account any deductions or retentions specified in the contract. This document ensures that the contractor is paid fairly for their work while also protecting the client’s interests by verifying that the agreed-upon scope of work has been executed.
