A Change Order is used to exchange or modify materials and/or work listed on the Scope for other materials or work. An Addendum is used to add additional work (labor and/or materials) to the Scope.

What are the types of change orders? The four most common types of change orders in construction are: lump sum (when the change can be quantified in price); zero cost (no change in price); time and material (cost cannot be estimated); and unitary cost (a change in scope that can be defined by measurement units).

The purpose of a change order It acts as an extension of the contract and ensures that all parties understand their new duties and expectations. It codifies the specific changes the client wants, and provides legal notice of any adjustments to the price and timeline that the client should expect.

A change directive or force account work is not the same thing as a change order. A change order requires agreement from the owner and other parties involved. A change directive is used to direct the contractor to perform additional work when there is not an agreement between the owner and contractor.

In construction, a change order refers to the documentation of an agreement to add or subtract work, alter the design, revise the schedule, modify the price, or deviate from the original project in some other way.

An amendment is typically used to change something that's part of an original contract. Think of amendments as modifications to the earliest agreement (for example, altering an agreed-upon deadline). An addendum is used to clarify and add things that were not initially part of the original contract or agreement.
