# Change Order (Variations) Clause

Sets a formal process for agreeing scope, price and timeline changes to work already contracted.

## Ce que c'est

A change order clause governs how the parties agree variations to the agreed scope of work (additional or reduced work, design changes, or new requirements). It defines who may request a change, how it is priced, and when it becomes binding.

## Pourquoi c'est important

Most disputes in projects arise from uncontrolled scope creep. A clear variation procedure prevents informal instructions from becoming unpriced obligations and protects both margin and schedule.

## Comment l'appliquer

- Require every variation to be in writing and signed before work begins.
- Specify how additional work is priced: agreed rates, cost-plus, or quotation.
- State the effect of a variation on the completion date and any milestones.
- Address reductions (minderwerk) and how credits are calculated.

## Conseils de négociation

- • Contractors should reserve the right to refuse changes that are technically unsafe.
- • Clients should cap the cumulative cost of variations or require pre-approval above a threshold.

## Pièges courants

- • Performing variations on a verbal instruction, then being unable to bill for them.
- • No agreed pricing mechanism, leaving the cost of changes to later dispute.

## Foire aux questions

Questions courantes sur cette clause.

- **Q:** Must a change order always be in writing?
  **A:** Not strictly by law, but a written, signed order is the only reliable way to prove the agreed scope and price.

- **Q:** Can a contractor charge for extra work the client did not formally approve?
  **A:** Only if the client should reasonably have understood it would increase the price; clear procedures avoid this argument.

- **Q:** Does a change order affect the project completion date?
  **A:** It should, if the variation affects critical path activities. A well-drafted clause requires the parties to agree a time extension at the same time as they approve the change.

- **Q:** What happens when the client instructs a reduction in scope?
  **A:** The contractor is generally entitled to a credit but also to loss of profit on the omitted work if the clause covers minderwerk. This must be stated explicitly.

- **Q:** Can the client instruct unlimited changes without the contractor's consent?
  **A:** No. Courts will refuse to enforce instructions that fundamentally alter the nature of the contract. A cap on cumulative variations is the cleaner contractual solution.
