15.4 Construction Process: Participating in Change Management

15.4 Participating in Change Management

Quick Answer: Changes during construction are documented through four instruments: bulletins (design clarifications that may have cost), AIA G710 Architect's Supplemental Instructions (minor changes with no cost or time impact), AIA G714 Construction Change Directives (direct the contractor to proceed before cost is finalized), and AIA G701 Change Orders (formal contract modifications signed by all parties when scope, cost, and time are agreed). Every change must be documented in writing and, if it affects cost or schedule, approved by the owner.

Why Change Management Matters

Changes are inevitable in construction. Unmanaged, they destroy budget, schedule, and trust. Managed through a documented process, they are routine. On the IDPX, change management is tested through the distinction between the four change instruments, the approval authority for each, and the cost and schedule implications of each.

The Four Change Instruments

Bulletins

A bulletin (sometimes called a design bulletin) is a designer-issued document that clarifies or changes the design intent. A bulletin that only clarifies an existing requirement has no cost; one that adds or changes scope may have cost and schedule impact and must be priced and approved as a change order. Bulletins are a project-management instrument, not a specific AIA numbered form.

AIA G710 — Architect's Supplemental Instructions (ASI)

The AIA G710, Architect's Supplemental Instructions, is the formal AIA form for additional instructions, interpretations, or minor changes that do not change the contract sum or contract time, authorized under AIA A201 §7.4. If the contractor believes the instruction does change cost or time, the contractor must notify the architect promptly so the change can be handled as a CCD or change order instead.

AIA G714 — Construction Change Directive (CCD)

The AIA G714, Construction Change Directive, is used when the owner and contractor have not yet agreed on the contract sum or time change, but the work must proceed expeditiously. Authorized under AIA A201 §7.3, the CCD is signed by the owner and architect only—the contractor's signature is not required. The contractor must promptly proceed; the cost adjustment can be proposed as a lump sum, unit price, or cost of the work plus a fee. Once cost and time are later agreed, a G701 Change Order incorporates the adjustment into the contract.

AIA G701 — Change Order

The AIA G701, Change Order, is the formal contract modification used when all parties have agreed on the change, including any adjustment to the contract sum and contract time. Authorized under AIA A201 §7.2, the G701 is signed by the owner, architect, and contractor and records the change description, the prior and new contract sum, and any change to the contract time and date of substantial completion.

Change Document Comparison

The Change Process

1. Need identified — owner request, RFI clarification, field condition, or contractor substitution proposal.
2. Designer documents the change — bulletin, sketch, or ASI.
3. Contractor prices the change — submits cost and schedule impact.
4. Owner approves or directs — if agreed, a G701 Change Order; if urgent and not agreed, a G714 CCD.
5. Change recorded — in the contract documents, ASI log, CCD log, and change-order log.

Substitutions and Value Engineering

A substitution is a contractor-proposed alternative product claimed equal to the specified product. Under AIA A201 §3.4.2, a substitution after award requires the Owner's consent after evaluation by the Architect, and is implemented by Change Order or Construction Change Directive. The designer reviews for conformance with the design intent—performance, materials, finish, and aesthetics—and accepts or rejects. An accepted substitution may carry a cost credit to the owner.

Value engineering (VE) is a contractor-initiated cost-reduction proposal suggesting alternative materials, systems, or methods that maintain function. The designer reviews VE proposals for design-intent conformance: a cheaper ceiling tile that does not meet the specified NRC rating must be rejected even if it saves money. Accepted VE proposals are implemented through a change order with a cost credit.

Cost, Schedule, and Recording

Every change affecting the contract sum or time must be documented in a G701 Change Order or G714 CCD. Schedule extensions must be justified against the baseline schedule and recorded in the change order. Changes are tracked through several logs that keep the contract record intact:

• ASI log — all G710 supplemental instructions.
• CCD log — all G714 directives and their later conversion to change orders.
• Change order log — all G701 change orders with cumulative contract sum and time.
• Architect's Supplementary Reports (ASRs) — in some contract forms, the designer's periodic field reports; the modern AIA equivalent is the site visit report and the ASI log.

Keeping these logs current is the designer's responsibility and the primary defense against end-of-project disputes.

Exam Scenario

An owner wants to add a custom reception desk after construction has started. The designer documents the change in a bulletin, the contractor prices it at $18,000 with a 5-day schedule extension, and the owner accepts the cost and time. The change is implemented through a G701 Change Order signed by the owner, architect, and contractor. If the owner wanted the work to start immediately before the contractor's price was finalized, a G714 Construction Change Directive would be used instead, with a G701 to follow once the cost is agreed.

Key Reminders

• G710 (ASI) = minor change, no cost or time.
• G714 (CCD) = proceed before cost is agreed, signed by owner and architect.
• G701 (Change Order) = agreed change, signed by all three parties.
• Substitutions and VE proposals require designer review for design-intent conformance.
• Every change must be documented in writing and logged.
