Construction Change Control Starts Before the Instruction

Construction projects generate change continuously. Some change is formal and visible: revised drawings, employer instructions, additional scope, design modifications or changed specifications. Other change is quieter: meeting comments, coordination adjustments, access resequencing, late approvals, buildability decisions, temporary works implications or requests made directly to site teams. These informal changes are often the most dangerous because they are implemented before entitlement, valuation and time impact are properly understood.

Effective change control starts before the instruction. A project team should be trained to recognise potential change triggers and route them through the correct process. Designers, construction managers, engineers, package managers and commercial teams should understand who has authority to instruct, how notices are issued, when quotations are required, how work proceeds under protest, and how records are captured.

The distinction between clarification and variation is especially important. Employers may see a design comment as clarification; contractors may see it as changed scope. Both positions may be reasonable depending on the contract and facts. The key is not to leave the issue unclassified. A change register should record the event, instruction source, contractual basis, notice status, valuation method, time impact and current assessment.
