Module 9: Project contractual structure, rights and obligations
Variations
The contract will normally contain a process by which the project owner or project engineer (if one has been appointed) can “vary” or “change” the contract work obligations. For example, change the:
building dimensions
materials to be used
drainage layout
lighting design.
The change can normally only be implemented through a formal written variation issued under the specified contract variation process.
The variation will normally result in any necessary consequent adjustment to:
the contractor’s price
the time the contractor has to complete the works.
