Where Section 4 candidates lose the most marks

Section 4 (Construction and practice) trips up a predictable set of candidates for predictable reasons. Most of the marks that go missing come from five well-documented gaps: shallow CCDC 2 clause knowledge, fuzzy understanding of the architect's role during construction, confused change management vocabulary, unclear shop drawing responsibilities, and thin coverage of professional practice basics. This post names each pattern, explains why it catches candidates, and tells you what to do about it.

Who this post is for

This post is for Intern Architects preparing for Section 4 of the ExAC who either work in a firm that does not do much construction administration, or who have done CA work but found Section 4 questions harder than expected. It is also for candidates who have already sat Section 4 and want to understand specifically why they missed marks before writing again.

If you have administered multiple contracts under CCDC 2 and read CHOP cover to cover within the last year, some of this will be review. If you are a recent graduate who has mostly worked on design projects, read carefully: Section 4 covers a phase of practice that experience-poor candidates often underestimate until they see their diagnostic feedback.

This is not a full reading list for Section 4. For that, see the 3-month ExAC study plan. This post is about where marks go missing and why, so you can allocate your remaining study time to the right targets.

The Section 4 category map

Section 4 covers four categories. The reading burden is uneven and the exam question weight is uneven. Understanding the shape of the section before you study it is the fastest way to allocate your time well.

Category Primary references Where marks go missing
Bidding and Contract Negotiations CHOP Ch. 6, CCDC 2 Procurement methods, bid irregularities, supplementary conditions structure
Construction Office Functions CHOP Ch. 5 and 6, CCDC 2 GC 5 and GC 8 Progress certificates, holdback, change order vs. change directive, shop drawing workflow
Construction Field Functions CHOP Ch. 5, CCDC 24 General review vs. inspection, site instruction authority, non-conforming work, substantial performance
Project and Business Management CHOP Ch. 3, RAIC Document 6, IAP Standard of care, fee structures, professional liability, scope of services

Construction Office Functions and Construction Field Functions carry the heaviest question loads and share the same root problem: candidates who have not read CCDC 2 closely enough to distinguish the architect's authority from the contractor's authority. The other two categories have their own specific gaps, covered in the sections below.

Pattern 1: CCDC 2 clause knowledge gaps

CCDC 2 is the standard Canadian stipulated price contract between the owner and contractor. Most candidates know it exists. Fewer candidates have read the General Conditions in the detail the exam requires. The questions on this contract are not abstract: they ask what a specific GC says about a specific situation.

The four General Conditions most commonly tested are:

  • GC 2 (Architect). What authority does the architect have? GC 2.1 defines the architect's role as agent of the owner for the purposes of the contract. GC 2.2 says the architect has no authority to issue instructions that alter the contract price or schedule without a change order. Candidates who do not know GC 2 miss questions about when the architect can and cannot direct the contractor.
  • GC 3 (Execution of the work). Who is responsible for temporary works, site safety, and construction means and methods? The contractor, not the architect. GC 3.3 places safety on the contractor. GC 3.5 covers the contractor's responsibility for the work until the date of substantial performance. Candidates who blur this line lose marks on field functions questions.
  • GC 5 (Payment). How does the progress certificate cycle work? The contractor submits a progress claim; the architect certifies the payment certificate within the prescribed period; the owner pays within the prescribed period. GC 5.5 covers holdback. If you cannot describe this cycle from memory, you are not ready for the payment questions in Section 4.
  • GC 8 (Changes). This is the change management General Condition, covered in its own section below. Know that the three change instruments (CCN, CD, CO) are all defined in GC 8 and that the differences between them are regularly tested.

The fix is straightforward: read CCDC 2 once in full, then mark up GC 2, 3, 5, and 8 and re-read them with specific questions in front of you. Do thirty to forty practice questions on Construction Office Functions and Bidding and Contract Negotiations before moving on. The questions will tell you exactly which clauses you understood and which you glossed over.

Pattern 2: The architect's role during construction

The single most tested distinction in Section 4 is the difference between general review and full inspection. It appears in multiple categories, in multiple question types, and in scenarios that look superficially different but test the same underlying principle: the architect is not the contractor's supervisor.

General review means periodic site visits to observe whether the work is generally in conformance with the contract documents. The frequency and scope of visits is a matter of professional judgment. The architect is not on site continuously, does not approve the contractor's schedule, and does not direct the contractor's trades or subcontractors.

Inspection implies continuous presence, monitoring of workmanship at every stage, and verification of compliance at a level the architect's standard engagement does not include. When the exam presents a scenario where the architect "should have caught" a problem that only continuous inspection would have revealed, the correct answer almost always notes that general review is not inspection and that the architect's obligation was met by periodic site visits and reviewing submitted documentation.

The related traps candidates fall into:

  • Verbally accepting non-conforming work. If the architect observes non-conforming work during a site visit, the correct response under CHOP and CCDC 2 is to issue a written site instruction (SI) directing the contractor to remedy the work. Verbal acceptance of non-conforming work is one of the most tested wrong answers in this category.
  • Taking over the contractor's role. The architect does not direct the contractor's means and methods, even when the contractor's approach looks problematic. The architect directs results (conformance with documents), not methods (how to get there). If a scenario offers the option to tell the contractor how to form a slab, that is a distractor: the architect can only require the slab to meet the design intent.
  • Misunderstanding substantial performance. Substantial performance of a contract is a specific legal threshold (typically defined in provincial lien legislation): the work must be capable of use by the owner for its intended purpose, with outstanding items not exceeding a prescribed value. The architect certifies substantial performance. Candidates who think the owner declares substantial performance lose marks.

CHOP Chapter 5 and CCDC 24 cover the architect's construction-phase role in the clearest language in the study materials. Read both before you start Construction Field Functions practice questions.

Pattern 3: Change management terminology

Section 4 regularly presents scenarios involving changes to the work and asks which instrument the architect should use. The three options are almost always: a contemplated change notice, a change directive, and a change order. Candidates who do not know the precise definition of each lose marks consistently.

Here is what each instrument is and when to use it:

  • Contemplated Change Notice (CCN). The architect issues a CCN to ask the contractor to price a potential change. The CCN does not authorize the contractor to proceed and creates no obligation on either party. Use a CCN when you want pricing information before committing to a change.
  • Change Directive (CD). The owner (through the architect) issues a CD when a change must proceed immediately but agreement on price has not been reached. The contractor is obligated to proceed under a CD; the cost is resolved later. Use a CD when time does not permit waiting for price agreement and the owner accepts the risk of an unresolved cost. This instrument is often misunderstood as optional or as requiring contractor agreement; it does not.
  • Change Order (CO). A CO is a formal amendment to the contract: it changes the contract price, scope, time, or some combination. It requires signatures from the owner and contractor (and typically the architect's signature as administrator). A CO is the only instrument that settles a change definitively. Use a CO once pricing is agreed and the change is ready to formalize.

The exam traps candidates by presenting a scenario where the wrong instrument is used: the architect issues a CO before pricing is agreed, or issues a CCN when the owner needs work to start immediately, or issues a CD when the owner and contractor have already agreed on price and a CO was the appropriate next step. Know the sequence and the trigger for each instrument.

All three instruments are defined in GC 8 of CCDC 2. They also appear in CHOP Chapter 5 with a more readable explanation of when to use each. Read both, in that order.

Pattern 4: Shop drawings and submittals

Shop drawing review is a specific, limited act. The architect reviews a shop drawing to confirm it is not in conflict with the design intent and contract documents. The architect is not reviewing it for structural adequacy of the contractor's connections, for the fabricator's production tolerances, or for constructability of the contractor's chosen sequence.

The stamp the architect places on a reviewed shop drawing says something close to "Reviewed for conformance with the design intent" (the exact language varies by firm). It does not say "Engineer of Record for this fabrication." Candidates who answer that the architect's shop drawing review shifts liability for engineering from the fabricator to the architect are wrong, and this is a regularly tested trap.

Three specific patterns that cost marks in this area:

  • Approving shop drawings for items outside the contract documents. If a contractor submits a shop drawing for an item not required by the contract, the architect should note that the item is not part of the contract and return it without review. Approving it without noting this fact creates an obligation the contract did not include.
  • Confusing late submittals with architect delay. The contractor is responsible for submitting shop drawings with enough lead time for the architect's review before the installation date. Delay caused by late submissions is the contractor's risk, not the architect's. When a question presents a scenario where late shop drawings delayed construction and asks who bears responsibility, the answer depends on whose fault the lateness was.
  • Failing to note deviations on the reviewed submittal. If the architect reviews a shop drawing and notes a deviation from the contract documents, that deviation must be noted on the returned submittal in writing. An "approved as noted" stamp with no written notes is a deficient review. The exam tests this procedural detail.

CHOP Chapter 5 covers the submittals process in the context of the construction office. The specific procedure for logging, reviewing, and returning shop drawings is also part of the Construction Office Functions category material.

Pattern 5: Professional practice and fees

The Project and Business Management category is where candidates who have not read RAIC Document 6 lose marks. Document 6 is the standard form of agreement between the client and the architect. It defines the scope of the architect's services, the fee structure, the standard of care, and the conditions under which either party can terminate the agreement.

The specific items most often tested in this category:

  • Standard of care. The architect's obligation under Document 6 is to provide services with reasonable skill, care, and diligence. This is not a guarantee of a defect-free building or a successful project outcome; it is a professional judgment standard. The exam tests whether you know this distinction and can apply it to a scenario where something went wrong on a project.
  • Scope creep and additional services. Document 6 distinguishes between basic services (included in the fee) and additional services (billed separately). If the client asks the architect to do something outside the scope of the base contract, the architect can and should invoice it as an additional service. The exam tests whether you know which services are basic and which are additional.
  • Professional liability insurance. The ExAC tests that you understand the difference between a claims-made policy (which covers claims made during the policy period regardless of when the error occurred) and an occurrence policy. Most Canadian architect errors and omissions insurance is claims-made. Candidates who do not know this lose marks on insurance scenario questions.
  • Client vs. owner. In Document 6, the other party is the "client." In CCDC 2, the other party is the "owner." These are often the same entity in practice, but the exam can test this distinction when asking about the architect's obligations under each contract. Know which contract you are reading and which term applies.

Read Document 6 once in full. It is shorter than CCDC 2 and less dense. CHOP Chapter 3 (practice management) covers the business of running an architectural firm in a way that complements Document 6. Candidates who read Document 6 without CHOP Chapter 3 are missing context on fees, project teams, and quality management that the exam also draws from.

What to skip on purpose

Section 4 has a long reading list. Not everything on it carries equal exam weight. Here is what you can safely deprioritize.

  • Memorizing CCDC 2 article numbers. The exam does not ask you to recite "GC 5.5." It asks what the contract says about holdback. Know the content of the clause, not the number. Time spent memorizing article numbers is time not spent on the content.
  • Reading RAIC Document 9 in depth for Section 4. RAIC Document 9 (the architect-to-consultant agreement) is less tested than Document 6. Know it exists and understand its general structure, but do not give it the same reading time as Document 6.
  • Studying CCDC 5A and 5B at clause level. The construction management contracts appear in the alternate project delivery reading. Know the conceptual difference between a construction manager at risk and a construction manager as agent. Do not memorize their General Conditions. The exam tests the concept, not the clause.
  • Reading every CHOP chapter equally. CHOP is long and not all of it feeds Section 4. Chapters 3, 5, and 6 are the core. Chapter 2 (the profession) is useful background. Read the Section 4-relevant chapters closely and skim the rest.
  • Treating the IAP handbook as a study document. The IAP experience framework confirms your hours and categories; it is not an exam study document. Know the experience categories and their descriptions, but do not allocate study sessions to reading the handbook as if it were a reference book.

If you are short on Section 4 prep time

If you have two weeks or fewer before the exam and Section 4 has not had enough attention, this is the priority order:

  1. Read CHOP Chapter 5 (design project management through construction) and Chapter 6 (the project phases, including construction through closeout). These two chapters cover more Section 4 ground per study hour than anything else on the reading list.
  2. Re-read CCDC 2 GC 2, GC 3, GC 5, and GC 8. Four General Conditions. They cover the architect's authority, the contractor's responsibilities, payment, and changes: most of the Construction Office Functions and Construction Field Functions exam content.
  3. Read RAIC Document 6 once, noting the scope of basic services, the standard of care clause, and the insurance requirements.
  4. Do 80 to 100 Section 4 scenario questions. Focus on the questions you get wrong. Trace each wrong answer back to the clause or chapter it came from and re-read only that part. Do not re-read whole documents at this stage; let the questions tell you what you do not know.

If you have been doing CA work at your firm, your experience with CCDC 2 and the construction phase is genuinely useful: it is easier to retain contract knowledge when you have seen the documents in use. That said, exam scenarios often involve edge cases that may differ from your firm's practices. Trust the documents over your firm's habits when they conflict.

Tools that actually help

For Section 4 specifically, the most useful study tool is a question bank with scenario-based questions that test CCDC 2 and CHOP at a clause level. Generic flashcards and chapter summaries will not surface the specific gaps this post describes. You need to be put in situations where you have to distinguish a change directive from a change order under time pressure, or decide whether the architect's shop drawing approval was appropriate given the facts of the scenario.

Examitect's practice question bank includes questions mapped to each of the four Section 4 categories, with explanations that cite the relevant CHOP chapter or CCDC 2 clause. Start doing those questions now, before you finish the reading. The questions will tell you what to go back and read.

The Examitect study schedule builds in dedicated time for Section 4 with specific daily reading targets for CHOP, CCDC 2, and Document 6. If you are writing all four sections in one sitting, that pacing matters.

FAQ

Section 4 FAQ

Section 4 (Construction and practice) is one of the four sections of the Examination for Architects in Canada. All four sections must be passed independently, so no single section counts for more than the others in terms of your licensure outcome. Within Section 4, the four categories carry different question loads, with the construction-phase categories (Construction Office Functions and Construction Field Functions) typically the heaviest.

Most candidates who flag Section 4 as difficult point to two areas: the architect's role during general review and the details of CCDC 2 change management. Both require you to know precisely what the architect is and is not responsible for during construction, and that line is subtler than it sounds on a first read of the contract.

Yes. Read CCDC 2 once in full, then re-read the General Conditions (Part 6) closely, especially GC 2 (architect's role), GC 3 (contractor's responsibilities), GC 5 (payment), and GC 8 (changes). The exam tests specific clause-level knowledge: who signs what, who carries temporary-works risk, and what the architect's authority is. Skimming is not enough for those four General Conditions.

General review means the architect makes periodic site visits to observe whether construction is generally in conformance with the contract documents. Inspection implies continuous monitoring of workmanship, means, and methods, which is not the architect's standard role. The ExAC regularly tests whether you can identify the architect's limits of authority, and confusing these two terms is one of the most reliable ways to lose marks in the Construction Field Functions category.

A contemplated change notice (CCN) is the architect asking the contractor to price a potential change, with no obligation to proceed. A change directive (CD) is the owner directing a change unilaterally when agreement on price cannot be reached; the contractor must proceed while the price is resolved. A change order (CO) is a formal agreed change to contract price, scope, or time, signed by the owner and contractor. These three documents appear together on Section 4 questions.

The architect reviews shop drawings for conformance with the design intent and contract documents. The architect does not approve the contractor's engineering, fabrication methods, or means and methods. Stamping a shop drawing does not shift the fabricator's engineering liability to the architect; it confirms the submittal has been reviewed and is not obviously at odds with the design intent.

CHOP is the primary reference across all four Section 4 categories. Chapters 3 (practice management), 5 (design project management), and 6 (the project phases including construction administration) account for the majority of Section 4 content. Candidates who read CHOP once without returning to Chapters 5 and 6 with practice questions in hand are underserving the section.

Yes. RAIC Document 6 is the standard client-architect agreement. The ExAC tests how the architect's fee is structured, how the scope of services is defined, what standard of care means for an architect, and how the contract handles disputes and termination. Plan to read Document 6 in full once and note the structure of the client's obligations vs. the architect's obligations.

Many candidates do, but it requires more active reading. If you have not administered a construction contract, CHOP Chapters 5 and 6 carry extra weight because you need to build a working mental model of the construction phase before the exam. Do scenario-based practice questions early so you have time to identify and fill the gaps rather than discovering them on exam day.

Holdback is the percentage (typically 10 percent in Canadian construction contracts) retained from each progress certificate pending substantial performance of the contract. It protects the owner against liens and deficiencies. The ExAC tests holdback in the context of progress certificates, substantial performance, and lien legislation, particularly in the Bidding and Contract Negotiations and Construction Office Functions categories.

Read CCDC 24 for general orientation on the general review role. It is shorter than CCDC 2 and frames the architect's site-visit responsibilities in plain language that supports your reading of the Construction Field Functions category. It does not carry as much exam weight as CCDC 2 or CHOP, so allocate time accordingly.

The architect's standard of care under RAIC Document 6 is reasonable skill, care, and diligence: not a guarantee of perfection or any particular outcome. The ExAC tests whether you understand the architect's obligations, the limits of those obligations, and how professional liability insurance (errors and omissions coverage) relates to claims made against that standard.

Aim for at least 80 to 100 Section 4 scenario questions, with an emphasis on construction administration categories. Scenario questions surface the gaps in your CHOP and CCDC 2 reading faster than re-reading does. Focus on the questions you get wrong: trace each back to the clause or CHOP chapter it came from and re-read only that section.
