Construction Phase: Office Functions

Construction Phase: Office Functions on the ExAC: the 3 sub-categories you need to know

Examitect's ExAC study plan splits Construction Phase: Office Functions into three sub-categories: 10.1 covers the roles of the architect and other participants, 10.2 covers the office tasks themselves, and 10.3 tests your ability to use the right form for each task. All three appear in Section 4 of the exam and draw primarily from CCDC 2, CCDC 24, and CHOP.

What office-side CA is, and what it produces

Office-side construction administration (CA) is the desk-based half of contract administration. It covers the documentation, certification, and change management tasks the architect carries out from the office rather than from the construction site. Field-side CA (site reviews, mock-up inspections) falls under sub-categories 11.1 and 11.2.

Six office tasks appear in almost every ExAC question set for this topic:

1. Reviewing shop drawings and submittals for general conformance with design intent
2. Responding to Requests for Information (RFIs)
3. Issuing Supplemental Instructions (SIs) for clarifications with no price or time change
4. Managing contract changes through the Proposed Change, Change Directive, and Change Order sequence
5. Certifying monthly progress payments
6. Maintaining project records: meeting minutes, field review reports, correspondence logs, and the Summary of Changes

10.1 Understand the roles of the architect and other participants in construction administration

What sub-category 10.1 tests. Sub-category 10.1 of Examitect's ExAC study plan, drawn from the CACB blueprint, is "Understand the roles of the architect and other participants in construction administration." The primary references are CHOP Chapters 3.8 and 6.6, and CCDC 2 Part 2.

Questions here ask you to identify who has authority over what, when, and in relation to whom. Most scenarios involve a three-party relationship: the owner, the architect (acting as Consultant), and the contractor.

The three-party structure under CCDC 2

CCDC 2 Part 2: the Consultant's authority

• GC 2.1 Authority of the Consultant. The Consultant acts on behalf of the owner only to the extent provided in the contract documents. Authority can be modified only with written consent of all three parties: owner, consultant, and contractor.
• GC 2.2 Role of the Consultant. The Consultant visits the site at intervals appropriate to the progress of construction, evaluates payment applications, issues Certificates for Payment, issues Supplemental Instructions, reviews shop drawings and submittals, prepares Change Orders and Change Directives, and conducts reviews for Substantial Performance. The Consultant's certificates are "to the best of the Consultant's knowledge, information and belief" but do not guarantee the work is correct or complete (GC 2.2.16).
• GC 2.2.5. The Consultant is not responsible for construction means, methods, techniques, sequences, or procedures. The Consultant is not responsible for the contractor's failure to perform.
• GC 2.2.6. The Consultant is the first interpreter of the contract documents in the event of dispute.
• GC 2.3 Review and Inspection. The owner and Consultant have access to the work at all times. If the contractor covers work before required tests are done, the contractor bears the cost of uncovering it.
• GC 2.4 Defective Work. The contractor must promptly correct defective work rejected by the Consultant. If correction is not practical, the owner may deduct the difference in value.

CHOP 3.8: risk management context for CA roles

CHOP Chapter 3.8 covers risk management and professional liability throughout the project life cycle, including during CA. It reinforces that the architect's authority as Consultant is defined by the client-architect agreement (RAIC Document 6) and the construction contract (CCDC 2). Key risks during CA include: taking on contractor responsibilities (cost: liability transfer), failing to respond to RFIs in a timely way (cost: delay claims), and inadequate shop drawing review records (cost: dispute over design intent).

10.2 Understand the office-function tasks associated with the construction phase

What sub-category 10.2 tests. Sub-category 10.2 of Examitect's ExAC study plan is "Understand the office-function tasks associated with the construction phase." Primary references include CHOP Chapters 5.3 and 6.6, CCDC 2 Parts 5 through 8, and CCDC 24. This is the broadest sub-category: it covers submittals, RFIs, SIs, change management, and payment certification. It is split across two study cards here for clarity.

Shop drawings and submittal review

The contractor submits shop drawings, samples, and product data to show the architect how they intend to build a portion of the work. The architect's job under GC 2.2.13 is to "review and take appropriate action." Four points examiners test repeatedly:

1. Review is for general conformance with design intent. The architect checks whether the proposed system, material, or detail is consistent with what the contract documents require. The architect does not verify the contractor's dimensions, quantities, means and methods, or site safety measures.
2. The contractor remains responsible for accuracy. Reviewing a shop drawing does not transfer the contractor's liability for errors in that drawing to the architect. The shop drawing cover letter and stamp must be worded carefully to make this clear (CHOP 6.8, Section 5.3).
3. Submittals flow through a hierarchy. CHOP 6.6 recommends reviewing system performance documentation first, then product specifications, then samples, so that decisions at the top of the hierarchy inform the review of items lower down.
4. Timeliness matters. Delay in reviewing submittals can extend the contract time and trigger claims. A log of all shop drawings and samples (CHOP 6.8, Form 5.4) tracks status and due dates.

Requests for Information (RFIs)

An RFI is a formal written request from the contractor for clarification when the contract documents are unclear, incorrect, or missing information. The architect must respond to every RFI. The response triggers one of two paths:

• No change in price or time: issue a Supplemental Instruction (SI).
• Change in price or time: initiate the change management process with a Proposed Change (PC), also called a Contemplated Change Notice (CCN).

Contractors sometimes abuse the RFI process by submitting unnecessary requests to build a paper trail for delay claims, or to make the architect responsible for information that is already available in the contract documents. CHOP 6.6 notes that the architect can add a supplemental condition to CCDC 2 allowing the cost of responding to unnecessary RFIs to be charged back to the contractor through a credit on the Certificate for Payment.

Supplemental Instructions (SIs)

An SI is an instruction that clarifies or interprets the contract documents with no change to contract price or contract time. CCDC 2 defines a Supplemental Instruction as "an instruction, not involving adjustment in the Contract Price or Contract Time, in the form of Specifications, Drawings, schedules, samples, models, or written instructions." If the Consultant realizes mid-issuance that the instruction involves a price or time change, a Proposed Change must be issued instead.

10.2 continued: the change management sequence

Change management is one of the highest-tested areas within sub-category 10.2. Under CCDC 2 Part 6 and CHOP 6.6, the process follows a defined sequence of forms. Knowing which form comes when is essential for the ExAC.

Step 1: Proposed Change (PC) / Contemplated Change Notice (CCN)

When a change to the work is identified, the architect prepares and issues a Proposed Change to the contractor. CCDC recommends the term "Proposed Change," but many offices still use "Contemplated Change Notice" or "Proposed Change Notice." The purpose is to alert the contractor to the proposed change and request a quotation covering any additional cost (or credit) and any adjustment to the contract time. PCs are assigned consecutive numbers and entered immediately on the Summary of Changes form.

Step 2a: Change Order (CO) when price is agreed

Under CCDC 2 GC 6.2, a Change Order records an adjustment to the contract scope that changes the contract price and/or contract time. It is prepared after the owner and contractor have agreed on the adjustments. A CO is signed by both parties. It is the final document in the change process when agreement is reached.

Step 2b: Change Directive (CD) when price is not agreed

Under CCDC 2 GC 6.3, if the contractor's price cannot promptly be agreed to, the architect may issue a Change Directive on behalf of the owner. A CD instructs the contractor to proceed with the change without waiting for a price agreement. It avoids delays when time-sensitive work is involved. The CD must be within the general scope of work described in the contract documents. Price is determined afterward, either by negotiation or by the methods set out in GC 6.3 (force account, unit prices, or quantum meruit).

The Summary of Changes

All PCs, CDs, and COs are tracked on a Summary of Changes form (CCDC 24). This form shows each change number, description, amount (credit or extra), and the running revised contract price. It is an essential document for certifying payment and for managing any future dispute about the final contract value. A cancelled PC retains its number so the sequence stays traceable.

10.2 continued: payment certification

Certifying payment is one of the most tested office tasks under sub-category 10.2. The architect does not pay the contractor; the architect certifies the amount the owner must pay. The owner then makes the payment. This distinction is tested in almost every ExAC Section 4 exam.

The monthly payment cycle

1. Contractor submits the Application for Payment. Monthly, using the CCDC 24 Application for Payment form, with supporting documentation tied to the agreed Schedule of Values.
2. Schedule of Values. Before the first application, the contractor submits a Schedule of Values breaking the contract price across trade sections. Under CCDC 2 GC 5.2.4, this must be submitted prior to the first payment application and must be approved by the Consultant.
3. Architect reviews and conducts a field review. The architect compares the application to the Schedule of Values and visits the site to confirm the percentage of work complete matches what the contractor is claiming.
4. Certificate for Payment issued. The architect issues the Certificate for Payment stating the amount owed. Under CCDC 2 Article A-5, the owner pays the certified amount, including any applicable Value Added Taxes.
5. Holdback retained. A statutory holdback percentage (varies by province) is retained from each progress payment until Substantial Performance is reached.

Key CCDC 2 payment provisions

• GC 5.4 Substantial Performance of the Work. Sets out how the contractor applies for, and the Consultant reviews and certifies, Substantial Performance as defined by the lien legislation at the Place of the Work.
• GC 5.5 Payment of Holdback upon Substantial Performance of the Work. Once Substantial Performance is reached, the retained holdback becomes due. In most provinces this is triggered by publication of a Certificate of Substantial Performance.
• GC 5.7 Final Payment. After Ready-for-Takeover and submission of all final documentation, the Consultant issues the Final Certificate for Payment covering the remaining contract balance.
• GC 5.8 Withholding of Payment. The architect may withhold certification in whole or in part if work does not conform to the contract documents.
• GC 12.3 Warranty. After Ready-for-Takeover, the contractor provides a one-year warranty. The owner, through the Consultant, notifies the contractor in writing of observed defects during this period.

Dispute resolution under CCDC 2 Part 8

When the contractor and owner disagree on a Consultant's finding, Part 8 sets out the process: first referral to the Consultant (GC 8.1, Authority of the Consultant), then negotiation, mediation, and finally arbitration (GC 8.2), with GC 8.3 preserving the parties' rights. Statutory adjudication, where provincial prompt-payment legislation provides for it, runs alongside the contract process rather than as a numbered GC. The Consultant's interpretation is the starting point, not the end point.

10.3 Demonstrate the use of administration forms

What sub-category 10.3 tests. Sub-category 10.3 of Examitect's ExAC study plan is "Demonstrate the use of administration forms." The primary references are CHOP Chapter 6.8 and all CCDC 24 model forms. Questions in this sub-category ask you to name the correct form for a given task, describe what content it must contain, or identify what a stamp notation means.

CCDC 24 model forms

CCDC 24 is not a contract. It is a guide to model administrative forms intended for use alongside CCDC 2. The most frequently tested forms are:

CHOP 6.8 forms

CHOP Chapter 6.8 provides forms that supplement CCDC 24, covering the broader project management record. The key forms are:

• Field Review Report (Form 3.1). Documents the architect's site observations: work in progress, deficiencies observed, actions required. Distributed within 48 hours of the visit.
• Minutes of Meeting (Form 1.3). Records decisions and action items from site meetings. Includes who is responsible for each action and the due date.
• Shop Drawing and Submittals Log (Form 5.4). Tracks the status of every required submittal: date received, date reviewed, review result, and date returned.
• Shop Drawing Review Stamp. Applied to each drawing reviewed. Typical notations are: "Reviewed" (general conformance confirmed), "Reviewed as Noted" (acceptable with noted conditions), "Revise and Resubmit" (changes required), and "Not Reviewed" or "For Information Only" (no review performed by the architect).

CHOP 6.8 explicitly states that it does not duplicate CCDC 24 forms. The two publications are complementary: CCDC 24 covers contractual forms; CHOP 6.8 covers office management and documentation forms.

How each reference fits the Construction Phase: Office Functions sub-categories

Each reference in Examitect's ExAC study plan for this topic contributes something distinct. Reading the right chapter at the right depth saves time and prevents gaps.

Key Construction Phase: Office Functions terms (glossary)

Application for Payment

The contractor's monthly submission requesting payment for work completed. Submitted using the CCDC 24 form and tied to the agreed Schedule of Values. The contractor submits it; the architect does not issue it.

Certificate for Payment

The architect's certification of the amount the owner must pay the contractor for a given period. The owner pays based on the certified amount, not based on what the contractor claimed.

Change Directive (CD)

A written instruction from the owner (via the architect) directing the contractor to proceed with a change when the parties cannot agree on the price. Issued under CCDC 2 GC 6.3. Price is determined afterward by negotiation or a prescribed method.

Change Order (CO)

The final agreed change to the contract scope, price, and/or time. Signed by both owner and contractor. Issued after the contractor's quotation has been accepted. Cannot be issued unilaterally.

Consultant

CCDC 2's term for the architect in the role of administering the construction contract. The Consultant acts on behalf of the owner only to the extent provided in the contract documents.

Contemplated Change Notice (CCN)

An informal term for a Proposed Change. CCDC recommends "Proposed Change," but many offices use CCN. Both request the contractor's quotation for a proposed change before a Change Order is issued.

Defective Work

Work rejected by the Consultant as failing to conform to the contract documents. Under CCDC 2 GC 2.4, the contractor must promptly correct it at the contractor's expense.

Holdback

The statutory percentage retained from each progress payment until Substantial Performance is reached. The percentage is set by provincial lien legislation and varies by province. It protects subtrades and suppliers who have lien rights.

Proposed Change (PC)

The CCDC-recommended term for a notice to the contractor describing a proposed change and requesting a quotation. It initiates the change management process. PCs are numbered sequentially; a cancelled PC keeps its number.

Ready-for-Takeover

CCDC 2's contractual term describing the point when the work is available for the owner's use. Defined in GC 12.1. Not the same as Substantial Performance, which is a statutory lien-act term.

Request for Information (RFI)

A formal written request from the contractor for clarification when the contract documents are unclear, incorrect, or missing information. The architect must respond to every RFI.

Schedule of Values

The contractor's breakdown of the contract price across trade sections or work elements. Submitted before the first Application for Payment and used as the basis for certifying monthly progress payments.

Shop Drawings

Under CCDC 2, "drawings, diagrams, illustrations, schedules, performance charts, brochures, Product data, and other data which the Contractor provides to illustrate details of portions of the Work." The architect reviews for general conformance with design intent; the contractor is still responsible for accuracy of dimensions, quantities, and means and methods.

Substantial Performance

A statutory milestone defined by provincial lien legislation. When reached, the lien holdback becomes due for release. The architect certifies the date of Substantial Performance. Definition varies by province; not the same as "Ready-for-Takeover" under CCDC 2, which is the milestone that starts the one-year warranty period under GC 12.3.

Summary of Changes

A running log of all Proposed Changes, Change Directives, and Change Orders, showing each item's status, credit or extra amount, and the revised contract price. Updated immediately when a change is initiated.

Supplemental Instruction (SI)

An instruction from the Consultant clarifying or supplementing the contract documents with no change to contract price or contract time. Defined in CCDC 2 as "not involving adjustment in the Contract Price or Contract Time." If a change to price or time results, a Proposed Change must be initiated instead.

Warranty Period

The one-year period following Ready-for-Takeover during which the contractor is responsible for defects. Under CCDC 2 GC 12.3, the owner notifies the contractor through the Consultant of defects observed during this period.

How Construction Phase: Office Functions questions are asked on the ExAC

Questions across all three sub-categories tend to be scenario-based: the examiners describe a situation during construction and ask what the architect should do, which form to use, or who is responsible. Multiple-choice distractors often give you a plausible-sounding answer that crosses a role boundary or uses the wrong form.

Common ExAC traps in Construction Phase: Office Functions questions

Six patterns account for most wrong answers in this topic. Knowing them in advance means you will see the trap before you hit it.

1. Confusing Change Directive with Change Order. A Change Directive is issued when the price has not been agreed and the work must proceed. A Change Order is issued when both parties have agreed on price and time. The exam often presents a situation where agreement is still pending and asks what to issue: the answer is Change Directive, not Change Order.
2. Saying the architect "approves" shop drawings. The architect reviews for general conformance with design intent. Using "approves" suggests the architect has verified all dimensions, quantities, and means of construction, which shifts liability incorrectly. The correct language is "reviewed" or "reviewed as noted."
3. Confusing a Supplemental Instruction with a Change Order. An SI clarifies without changing price or time. If the situation involves any cost or schedule impact, an SI is not the right form. You must initiate a Proposed Change first, then issue a Change Order or Change Directive.
4. Having the architect pay the contractor. The architect certifies payment; the owner pays. Distractors will describe scenarios where the architect "pays" the contractor or "releases" the holdback. The architect issues the Certificate; the owner writes the cheque.
5. Mixing up Substantial Performance and Ready-for-Takeover. "Substantial Performance" is the provincial lien-act milestone that triggers holdback release. "Ready-for-Takeover" is CCDC 2's contractual term. They are not the same, even though they often occur close together on a project.
6. Treating CCDC 24 as a contract. CCDC 24 is a guide to model forms. It is not a contract. Questions that ask whether a contractor is "bound by CCDC 24" are testing whether you know its nature. The contractor is bound by CCDC 2; CCDC 24 supports its administration.

Tips for Intern Architects studying Construction Phase: Office Functions

• Read CCDC 2 Part 2 closely. GC 2.1 through 2.4 are four clauses that appear directly in ExAC questions. Know what each clause covers, not just its title. GC 2.2.5 (not responsible for means and methods) and GC 2.2.16 (certificate does not guarantee the work) come up in scenario questions regularly.
• Learn the change sequence, not just the names. You need to know: RFI leads to SI or PC/CCN; PC/CCN leads to CO if agreed, or CD if not. The exam gives you a scenario and you must identify where in the sequence the project is and what comes next.
• Memorize the payment cycle steps. Five steps: (1) contractor submits Application; (2) architect reviews against Schedule of Values; (3) architect conducts field review; (4) architect issues Certificate for Payment; (5) owner pays. Knowing which party does which step prevents the most common payment errors.
• Know CCDC 24 form names and their issuers. The contractor issues the Application for Payment. The architect issues the Certificate for Payment. Knowing who issues each form prevents role-confusion errors. This is a fast point on the exam if you have memorized the table.
• Read CHOP 6.6's appendices. The checklists for the pre-construction meeting agenda, the shop drawing review process, and the field review items are all testable. Examitect questions draw on these checklists directly.
• Understand holdback at a provincial level. Know that holdback is statutory, that the percentage is set by lien legislation (not CCDC 2), and that it is released after Substantial Performance. You do not need to memorize every province's percentage, but you must know the principle.
• Keep field and office functions separate. Sub-categories 10.1 to 10.3 test office-side work. Sub-categories 11.1 and 11.2 test field-side work (site reviews, mock-ups, field instructions). When the exam asks an office functions question, the answer should not involve the architect going to the site to resolve the issue.
• Practise with Examitect questions for all three sub-categories. 10.1 (roles), 10.2 (tasks), and 10.3 (forms) each have a different question shape. Practising across all three builds the pattern recognition you need to answer quickly and correctly on exam day.

How to study Construction Phase: Office Functions in 15 to 20 hours

1. Hours 1 to 2: Read CCDC 2 Part 2 (GC 2.1 to 2.4) and Part 5 (GC 5.1 to 5.7). Focus on clause purpose, not just the heading.
2. Hours 3 to 4: Read CCDC 2 Part 6 (Changes) and scan Parts 7 and 8. Know the difference between GC 6.2 (Change Order) and GC 6.3 (Change Directive).
3. Hours 5 to 8: Read CHOP Chapter 6.6 in full. This is a long chapter: work through the office functions section, the change management sequence, the submittal review guidance, and the payment certification procedures.
4. Hours 9 to 10: Read CCDC 24 in full. For each model form, read the Guideline section and the sample form. Note what content each form must contain.
5. Hours 11 to 12: Read CHOP 6.8. Focus on the shop drawing stamp language, the Field Review Report content, and the Summary of Changes form.
6. Hours 13 to 14: Skim CHOP 3.8 for the risk management sections that apply to CA. Pay attention to the GO/NO GO context and the professional liability implications of CA decisions.
7. Hours 15 to 20: Work through Examitect practice questions for all three sub-categories. Flag questions where you are unsure of the correct form or role, and return to the relevant clause in CCDC 2 or CCDC 24 to confirm the answer.
