Frequently asked questions

What is a Change Order Request?

A COR is a contractor's formal, priced request to perform work outside the original contract scope, documenting the cost and time impact for the owner's approval.

What is the difference between a COR and a change order?

A COR is the contractor's proposal; it becomes a change order once the owner approves and it is executed as a formal amendment to the contract.

What should a COR include to get approved faster?

Clear scope, itemized labor and material pricing, schedule impact, and a reference to the RFI, directive, or drawing that caused the change.
