Extension

In procurement, an extension is a modification to the timeframe of a contract arrangement to allow more time for outputs and/or deliverables to be completed. An extension is typically arranged when unexpected or unavoidable delays impede goods or services from being provided within an agreed timeframe. A modification agreement signed by both the buyer and the supplier is required for an official extension to be recognised as part of the agreement. The included modifications must not significantly alter the deliverables or purpose of the original agreement, and typically only alter the due dates associated with certain aspects of the project.
