Among contract documents, the Conditions of Contract stipulates the change order procedures to follow for change orders (variations) of a construction project. Conditions of Contract is one of the volumes of contract documents as well as in tender documents, and consists of terms and conditions which govern the contracting parties’ rights and responsibilities, hence is important for parties to understand the contractual requirements for submitting legitimate change orders including, but not limited to, notice provisions, timing, structure of the change orders, information required to support the change orders, acceptance and approval procedures.

It is important for the parties to consistently follow the change order procedures in the contract. Failure to do so may set a precedent for handling change-related situations outside of the contract, or gives rise to disputes, or may be perceived as a waiver of contract requirements.
