Section 4: Construction and Practice

The ExAC Framework Document's Table of Specifications gives 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 objective 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.

Not as a named objective. The published 2026 objectives for topic 12 run 12.1.1 to 12.1.7 and cover the project management process, the roles of the people on a project, the project file, the work plan, team management, quality assurance, and the methods used to calculate the architect's fees. None of them names professional ethics, conflict of interest, complaints, or discipline, and neither the Preparation Guide nor the ExAC Framework Document lists ethics as examined content. Professional judgment still shows up inside scenarios, so read CHOP Chapter 1.3 for the background and treat any ethics-flavoured question as a process question, not a personal-opinion question.

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.

Not the writing order. A first-time candidate writes all four sections in one sitting, four three-hour sessions over two consecutive days, in the published order. The sections are marked pass or fail independently, and only the sections you fail are rewritten at a later sitting. What you can order is your study plan: Sections 1 to 3 cover the design, code, and technical work that feeds Section 4's paperwork, so leaving Section 4 review until last lets your other prep carry into it.

Closed book. Under the ExAC Preparation Guide, paper copies of NBC 2020 and NECB 2020 are permitted during the Section 2 examination only, and books, notes, or reference documents are prohibited items in every other section, Section 4 included. The authority is the ExAC Preparation Guide published by the Committee for the ExAC at exac.ca. Examitect's practice bank therefore treats Section 4 as closed-book, so you train to 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; CCDC calls it a proposed change, and the CCDC 24 model form is the Proposed Change Form. A Change Order confirms a change to contract price, time, or scope, and it carries three signatures on the CCDC 24 Change Order Form: the Consultant signs first recommending the change, then the Owner signs approving it and the Contractor signs approving it. A Change Directive is what the Owner uses when the parties cannot agree on price or time but the work has to proceed anyway; there the Consultant prepares it, the Owner issues and signs it, and the Contractor signs only to acknowledge receipt. 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, and it starts the lien holdback release clock. Ready-for-Takeover is the 2020 CCDC 2 addition: the contractor delivers certificates, manuals, training, and commissioning, the Owner can take over the building, and the one-year warranty period starts under GC 12.3.1. CCDC 2 (2020) has no third milestone called Total Performance; after Ready-for-Takeover the Contractor establishes a reasonable date for finishing the Work (GC 12.1.5) and then applies for final payment under GC 5.5.

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 is where the term is defined (Chapter 6.6 and its Appendix A, Professional Standards for Field Review/General Review). CCDC 2 (2020) never uses the phrase: GC 2.2.2 has the Consultant visit the Place of the Work at intervals appropriate to the progress of construction to determine if the Work is proceeding in general conformity with the Contract Documents. Neither is continuous supervision, and neither is 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 Six (2022) cover seven phases, and Article A13 apportions a fixed or percentage fee across them: pre-design, schematic design, design development, construction document, bidding or negotiation, construction, and post-construction. 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. There is only one holdback under CCDC 2 (2020): the lien holdback, which becomes due no later than 10 Working Days after the statutory holdback period expires (GC 5.4.3). The remaining balance of the Contract Price is paid under GC 5.5 Final Payment once the Work is complete. 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.
