Keep in mind: Investigate material variance in context. Check whether scope, quantity, specification, timing, exclusions, tax, or classification changed before drawing a conclusion from a percentage.

1. Pre-Construction

How to use the Variation Log

Record proposed changes before authorising work and follow the variation process in the contract and applicable law. Verbal changes can create cost, scope, authority, and evidence disputes; obtain written details and advice where appropriate.
