Change order versus construction change directive

Construction work changes after award for many reasons: concealed conditions, owner requests, design coordination, code requirements, or product availability. The contract needs a controlled way to authorize a change, define its scope, and track its effect on price and time. A change order and a construction change directive are related tools, but they are not interchangeable labels in every contract.

What a change order does

A change order is a written amendment that identifies the changed work and adjusts the contract documents as applicable. In common standard forms, the owner, contractor, and architect or other designated contract administrator sign or approve the change order. It typically states the change in scope, the adjustment to the contract sum, any adjustment to the contract time, and the effective date or related schedule treatment.

What a construction change directive does

Some standard form contracts provide a construction change directive as a mechanism for directing a change before the parties agree on the final adjustment to price, time, or both. It lets the project proceed under the contract's stated process while the adjustment is documented or later resolved. A directive is available only if the governing contract includes and authorizes that mechanism; a project participant cannot invent one by using the phrase on a field memo.

Why the distinction matters

If the owner requests a scope change and all required parties agree on the price and schedule effect, a change order can capture that agreement. If the work must be directed before the adjustment is settled, an authorized directive may provide a path forward. The contract determines who can issue it, what records must be kept, how costs are valued, and how a disagreement is handled.

Document the change before the work drifts

• Identify the contract clause and the person authorized to request, approve, or direct the change.
• Describe the changed scope precisely, including drawings, specifications, exclusions, and affected trades.
• Record the proposed or agreed cost, schedule effect, and method for measuring any unresolved adjustment.
• State whether the work is authorized to proceed and what notice or reservation is required.
• Update the change log, schedule, budget, subcontracts, and payment records after approval.
• Retain the supporting proposal, field reports, correspondence, pricing detail, and signed instrument.

Example

An owner asks for a different storefront configuration. The contractor prices the revised material and labor, the designer confirms the revised details, and the owner accepts the price and a three-day extension. The parties document those terms in a change order before the revised work is incorporated. If the project form allows a construction change directive and the owner directs the change while the final price remains disputed, the contractor documents labor, material, equipment, and schedule effects using the contract's directive procedure.

Common exam traps

• Assuming every construction contract includes a construction change directive.
• Treating a directive as a substitute for written notice, cost records, or contract authority.
• Ignoring time impacts because the dollar price is the most visible part of the change.
• Starting changed work based only on an informal conversation when the contract requires written authorization.
• Confusing a request for proposal or field report with approval to change the contract.

How to answer a contract question

First determine whether the parties have agreed on the change and its price and time effect. Then check which instrument the contract authorizes and who may issue it. Use “change order” for the documented agreed amendment; use “construction change directive” for a contract-defined direction that may proceed before the adjustment is fully agreed. Qualify the answer by the specific contract form.

Key takeaway

A change order records an agreed contract change. A construction change directive may direct changed work before agreement on the adjustment, but only where the contract authorizes it. Scope, signatures, pricing, time, and dispute procedures come from the executed contract.
