Change and Variation Claims

Variations are an inevitable part of construction projects and a clear understanding of how to properly manage variation claims is critical to maintaining project delivery, protecting contractual entitlements, and minimising the risk of disputes.

This article focuses on common types of variation claims. For more detail on administering variations, including the processes under bespoke and Australian Standards contracts, powers to vary, and valuation methods, we recommend reading our earlier article from our Contract Administration Series. That article can be found via the link in the comments.
