Differentiate between a Change Order and a Construction Change Directive in A201.

• A. A Change Order is a written agreement adjusting the contract sum and time; a CCD is an interim directive authorizing a change before agreement on price/time, later resolved by a Change Order.
• B. A CCD adjusts the contract sum and time; Change Order authorizes a change before agreement.
• C. A Change Order is issued by the Architect; a CCD is issued by the Owner.
• D. A CCD permanently changes the contract price without time adjustment.

Answer: (D)

The key idea is that a Change Order is the formal, signed agreement that actually adjusts the contract sum and the contract time. It finalizes the change with specific numbers for cost and any schedule impact, and it reflects the negotiated agreement between the owner and contractor (with the architect often facilitating).

A Construction Change Directive is different: it is an interim directive from the architect that authorizes a change in the work to proceed before the price and time are settled. It keeps the project moving while the parties negotiate or determine the final terms. The CCD itself does not finalize the price or the schedule; the final changes are made later through a Change Order (or other agreed settlement).

So, the CCD is a temporary authorization to change the work pending later agreement on cost and time, whereas the Change Order is the final, signed amendment that actually changes the contract sum and/or the contract time.
