Managing Scope Creep & Construction Changes

Managing Scope Creep & Construction Changes

Managing changes effectively is the hallmark of a skilled project manager. Uncontrolled changes during design erode architectural profitability, while mishandled changes during construction lead to contractor delay claims, budget blowouts, and adversarial dispute proceedings.

Scope Creep vs. Design Refinement

A frequent source of financial loss for architectural firms is failing to recognize the boundary between normal design detailing and client-driven scope creep:

Design Refinement

• Definition: The natural, iterative process of translating broad conceptual designs into coordinated, constructible assemblies without altering the programmatic requirements, building footprint, functional performance, or quality tiers established in the agreement.
• Examples: Sizing structural steel members following engineering calculations; detailing roof flashing flash-points; coordinating ductwork drop locations through joist spaces; selecting standard hardware finishes within the specified allowance.
• Contract Status: Fully covered under the Architect's Basic Services (AIA B101 Article 3). The architect cannot bill additional fees for standard detailing and interdisciplinary coordination.

Scope Creep

• Definition: The continuous, unmanaged growth of the project's physical scope, spatial program, performance standards, or deliverable requirements without a corresponding increase in architectural fees or schedule adjustments.
• Examples: An owner adding a commercial teaching kitchen to an elementary school design after schematic sign-off; upgrading an exterior envelope from painted stucco to imported terracotta rainscreen panels; adding 3,500 square feet of office shell space; requesting three-dimensional photorealistic marketing renderings not included in Article 4.
• Contract Status: Constitutes an Additional Service under AIA B101 Section 4.2.1. The project manager must provide prompt written notice to the Owner's Designated Representative and receive formal written authorization before performing the work.

Construction Phase Change Instruments: The Big Three

Once the construction contract is executed (AIA Document A101/A201), the architect cannot unilaterally alter the contract between Owner and Contractor. Construction modifications are strictly categorized into three administrative instruments:

                    CONSTRUCTION CHANGE INSTRUMENTS
                                   │
         ┌─────────────────────────┼─────────────────────────┐

1. AIA Document G701: Change Order

AIA Document G701–2017 is the formal instrument used to modify the construction contract when there is complete mutual consensus among all three parties.

The Tripartite Signature Rule

Under AIA Document A201–2017 Section 7.2.1, a Change Order requires the agreement and signatures of:

1. The Owner
2. The Contractor
3. The Architect

Core Elements Documented on Form G701

• Detailed description of the change in the Work;
• The original Contract Sum;
• Net change by previously authorized Change Orders;
• The Contract Sum prior to this Change Order;
• The amount by which the Contract Sum will be increased or decreased;
• The new Contract Sum including this Change Order;
• The adjustment in Contract Time (number of calendar days added or deducted);
• The revised date of Substantial Completion.

Legal Significance and Finality

A signed Change Order records agreement on the described scope, price, and time. Its release language determines the extent of settled claims. Document reservations and unresolved impacts rather than assuming every G701 automatically releases all later or unrelated claims.

2. AIA Document G714: Construction Change Directive (CCD)

In fast-paced construction, situations arise where modifications must proceed immediately to prevent project paralysis or structural damage, but the Owner and Contractor have not yet agreed upon adjustments in cost or contract time. In these scenarios, the architect issues an AIA Document G714–2017 Construction Change Directive.

The Two-Signature Rule

Under AIA Document A201–2017 Section 7.3.1, a Construction Change Directive requires the signatures of:

1. The Owner
2. The Architect

Crucially, the Contractor's signature is NOT required to issue a valid CCD. It is a unilateral directive backed by the owner's financial authority.

The Contractor's Mandatory Duty to Proceed

Under A201 Section 7.3.6, upon receipt of a valid CCD signed by Owner and Architect, the Contractor shall promptly proceed with the change in the Work. The contractor cannot strike, halt construction, or delay the critical path while arguing over pricing.

Contractor Response Scenarios

• Agreement: If the contractor agrees with the proposed adjustment in Contract Sum and Time stated on the G714, the contractor signs and returns the document. Under Section 7.3.7, such agreement becomes effective immediately as a Change Order.
• Disagreement: If the contractor disputes the proposed cost or schedule adjustment, the contractor proceeds with the work, and the final adjustment is determined under Section 7.3.4.

The Four Methods of Determining Cost Under A201 § 7.3.3

When a CCD is issued, the adjustment to the Contract Sum is calculated using one of four contractual methods:

1. Mutual Acceptance of a Lump Sum: An itemized, agreed lump sum properly supported by substantiating data.
2. Unit Prices: Unit prices stated in the Contract Documents or subsequently agreed upon.
3. Cost Plus Fee: Cost to be determined in a manner agreed upon by the parties and a mutually acceptable fixed or percentage fee.
4. Architect's Determination Under § 7.3.4 (Force Account / Time and Materials): If the parties cannot agree on methods 1–3, the cost is determined by the Architect based on actual expenditures.

Allowable Costs Under A201 § 7.3.4

Under Section 7.3.4, the contractor must maintain daily itemized records (time cards, material receipts, equipment invoices). The Architect determines the cost based on strictly defined allowable expenditures:

• Direct payroll costs for workers and jobsite supervisory personnel, including social security, old age, unemployment insurance, and fringe benefits;
• Costs of materials, supplies, and equipment, including delivery and transportation costs;
• Rental costs of machinery and equipment (exclusive of hand tools) rented from the contractor or others;
• Costs of premiums for all bonds, insurance, permit fees, and sales/use taxes related to the work;
• Additional costs of jobsite supervision and field office personnel directly attributable to the change.

3. AIA Document G710: Architect's Supplemental Instructions (ASI)

Not every field clarification involves monetary adjustments or schedule extensions. When minor design clarifications are required, the architect issues an AIA Document G710–2017 Architect's Supplemental Instructions (ASI).

The Single Signature Rule

Under AIA Document A201–2017 Section 7.4, the Architect has the unilateral authority to order minor changes in the Work that do not involve an adjustment in the Contract Sum or an extension of the Contract Time, and that are consistent with the intent of the Contract Documents. An ASI requires only the Architect's signature.

Typical ASI Applications

• Clarifying an ambiguous dimension between two non-bearing interior partition walls;
• Specifying paint color selections from the manufacturer line already identified in specifications;
• Adjusting the layout of ceiling supply diffusers to coordinate with lighting fixtures without altering equipment counts or duct sizes;
• Providing an enlarged detail clarifying a standard window sill flashing condition.

The Contractor's Recourse If Cost or Time Is Affected

Under A201 Section 7.4, the contractor must evaluate every ASI upon receipt. If the Contractor believes that the instructions in an ASI will cause an increase in the Contract Sum or Contract Time, the contractor must NOT proceed with the work. The contractor must give prompt notice to the Architect and not proceed under § 7.4; any subsequent claim also has the applicable Article 15 requirements. If the contractor proceeds without providing timely written notice, the contractor waives any right to claim an increase in price or time.

Comparative Analysis of AIA Construction Change Instruments

Service changes and construction changes use different agreements. Review a proposed change for engineering redesign, professional fee, critical-path effect, construction cost, permitting, and owner financing. A signed construction Change Order does not automatically amend B101 or C401. Likewise, a service amendment does not change the contractor's price or time. Do not assume that verbal directions always forfeit all compensation or that every change order automatically releases unrelated claims; authorization and release wording matter.
