When is it permissible to direct a contractor to perform a task that is not within the contract's scope of work?

It is permissible to direct a contractor to perform a task outside the contract's scope of work when both parties agree to the change, typically through a written change order or amendment. This ensures that the contractor is compensated appropriately for the additional work and that there is clarity on the expectations. Additionally, the change should not significantly alter the project's original intent or objectives. Always consult the contract terms for any specific procedures regarding modifications.
