Section 4: Construction and Practice

The ExAC blueprint lists about 130 multiple-choice questions for Section 4, making it the largest multiple-choice section of the exam. Those questions span four topics across contract negotiation, construction administration, and practice management, so plan for a meaningful share of your overall exam workload. Examitect's practice bank mirrors the official ExAC Study Plan weighting.

Most interns don't have direct contract-administration or construction-phase exposure yet. The section assumes practising-architect familiarity with field reviews, payment certification, change orders, and substantial performance. If you've only worked in early design phases, plan to over-prepare on Office Functions and Field Functions.

No, but you should know the document's article structure cold, the role of each party, and the major clauses around payment, changes, substantial performance, and ready-for-takeover. Examiners test whether you can find a clause quickly, not whether you can recite it.

Construction Office Functions covers paperwork from the desk: shop drawing reviews, RFIs, CCNs, change orders, payment certificates, and contract administration logs. Construction Field Functions covers site work: field reviews, observation reports, deficiency tracking, substantial performance certification, and takeover.

Yes. Several questions per sitting touch on the regulator's role, conflict of interest, complaint procedures, and the architect's fiduciary duty during payment certification. Treat ethics questions as process questions, not personal-opinion questions.

Bidding and Contract Negotiations is the topic most candidates underestimate. CCDC 2 is dense, the article structure takes time to learn, and the supplementary conditions trip people up. Construction Field Functions is a close second if you've never run a site visit, written an observation report, or certified substantial performance.

Plan for 50 to 70 hours of focused study, roughly 12 to 18 hours per topic. Spend more on Bidding and Contract Negotiations and the two construction-phase topics if those are outside your day-to-day work, and less on Project and Business Management if you already handle fee proposals or run files in your firm.

Many candidates do. Sections 1 to 3 cover design, codes, and the technical work that feeds Section 4's paperwork, so writing Section 4 last lets your other prep carry into it. That said, the four ExAC sections are written and graded independently, so you can sit them in any order that fits your schedule.

ExAC sitting rules can vary by year and jurisdiction. Check the current CACB ExAC handbook for the rule that applies to your sitting. Examitect's practice bank treats Section 4 as closed-book because that's the harder default to train against, and most candidates report stronger performance when they can answer without flipping through CCDC 2 or CHOP.

Multiple-choice only. Section 4 has about 130 multiple-choice questions and no short-answer questions; written responses appear only in Sections 1 and 3. Many stems are still scenario-based, where you read a short project situation and the right option hinges on a clause in CCDC 2 or a process step in CHOP. The Examitect practice bank mirrors this format.

Section 4 is a three-hour session. The ExAC runs as four three-hour sessions over two consecutive days, one session per section. With about 130 multiple-choice questions in three hours, you have roughly 80 seconds per question, which is why mock-exam practice under time pressure is so valuable.

A CCN (Contemplated Change Notice) is the consultant asking the contractor to price a possible change before any work begins. A Change Order is the signed document that confirms a change to contract price, time, or scope; the Consultant prepares it, and the Owner and Contractor sign it. A Change Directive is what the Owner uses when the parties can't agree on price or time but the work has to proceed anyway. ExAC tests this sequence directly.

Substantial Performance is reached when the Work is ready for use or being used for its intended purpose, triggered by a formula in provincial construction lien legislation. Ready-for-Takeover is a 2020 CCDC 2 addition: the contractor delivers certificates, manuals, training, and commissioning, and the Owner can take over the building. Total Performance is when every deficiency is corrected and every contract obligation is complete. Each milestone changes the holdback and warranty clocks.

A field review is the architect's periodic, general visit to the site to determine whether the Work is, in general, in conformance with the contract documents. CHOP and CCDC 2 GC 2 both define it as periodic and general, not continuous supervision and not direction of means and methods. Frequency varies by project complexity and is set out in RAIC Document 6 or the architect's services schedule. Document every visit in writing.

Basic services under RAIC Document 6 cover the standard architect-led phases: pre-design, schematic design, design development, construction documents, bidding and tender, and contract administration. Additional services are anything outside that scope, like building information modelling beyond the contract, post-occupancy evaluation, expert-witness work, or redesign caused by an owner change. Section 4 fee-proposal questions often test whether you can identify a request as basic or additional and propose the right billing method.

Statutory holdback is set by provincial construction lien legislation, often 10 percent of the value of work certified. The Owner withholds the holdback from each payment to the Contractor until the lien period expires after publication of Substantial Performance, at which point the lien holdback is released. A separate final holdback is released after Total Performance. CCDC 2 GC 5 tracks the contract side; the provincial lien act tracks the statutory side.

A bid bond guarantees that the winning contractor will sign the contract and provide further security after award; it is in place during the tender period only. A performance bond covers the Owner if the Contractor fails to complete the Work according to the contract. A labour-and-materials payment bond covers payments owed to subcontractors and suppliers. All three are issued by a surety, not by the contractor's bank.

Read CHOP's construction-administration chapter first, then CCDC 2 cover to cover. If you can, sit down with the architect running CA on a project in your office and walk through the paperwork. The exam doesn't test how many sites you've visited; it tests whether you know what each CA document is for and which party owns which step. The CA acronyms in the Numbers to memorize card are the highest-yield study list.

Section 4 prep is the section that most directly trains your professional judgment. Programming and Cost Management decisions from Section 1 are framed by the Section 4 contract you'll later sign. Construction Documents and Specifications work from Section 3 becomes the contract documents your Section 4 paperwork references. The lane-discipline habit you build for Section 4 carries everywhere on the exam.

No, but you should read the practice-management, bidding, and construction-administration chapters cover to cover. CHOP is the spine of Section 4, and those chapters are the most-tested portion of the entire reference. The earlier chapters on project setup are useful for Project and Business Management. The rest can be skimmed.
