Control variations and changes

A written variation is a decision record. It should make the change clear to both sides, not merely add a price.

Record the complete change

  • Reason and requested-by party
  • Original and revised scope
  • Price addition or deduction
  • Programme effect
  • Drawing or specification revision
  • Approval date and parties

Handle urgent site discoveries proportionately

Ask for photographs, an explanation, options and the cost/time effect. If immediate safety action is required, record what was made safe and keep the permanent solution as a separate decision.

Maintain a running total

Update the agreed contract sum and completion forecast after each approved variation so the project position remains visible.

Before you move on

  • No material change rests only in chat
  • Price and time effects recorded
  • Drawing revisions identified
  • Running total updated

General education only. Requirements depend on the property, proposed work, approvals and contract. Check the current agency guidance and use an appropriate qualified professional when the work or dispute needs one.
