Why CCDC 24 matters for the ExAC

CCDC 24 is the document the ExAC reaches for when a question asks "which form should the architect issue" or "what information should that form contain." Examitect's ExAC study plan lists it as a primary resource for two Bidding and Contract Negotiations objectives (procedures for awarding a contract; evaluating bids) and two Construction Phase Office Functions objectives (the office-function tasks of construction administration; demonstrating the use of administration forms).

The language of the exam also tracks the language of CCDC 24. Terms like Proposed Change, Change Order, Change Directive, Supplemental Instruction, Application for Payment, and Certificate for Payment come straight from the model forms in this guide and the General Conditions in CCDC 2. Knowing which instrument fits a given situation is one of the more reliable ways to move from a 60-percent answer to a confident answer on Section 4 questions.

If you only had time to study one CCDC document beyond CCDC 2 itself, this would be it.

Section 4

What CCDC 24 is

CCDC 2 refers, either expressly or by implication, to a series of administrative processes and forms. CCDC 24 is the guide that brings those processes together in one document and provides example model forms for each one. According to its own introduction, the purpose is to help users of CCDC 2 meet the administrative requirements set out in that contract by providing a short explanation of each process, a narrative on how to use the form, a checklist of what the form should contain, and an example of the model form itself.

CCDC 24 covers prequalification of contractors, financial information disclosure by the owner, the payment process, supplemental instructions, the change process, notifications, and warranty notices. It also reproduces three related CCDC standard forms in its appendices: CCDC 11 (Contractor's Qualification Statement), CCDC 12 (Project Financial Information), and CCDC 9A and 9B (Statutory Declarations). The 2016 edition was developed for use with the CCDC 2 (2008) contract, and the forms remain in active use on projects administered under the newer CCDC 2 (2020) edition.

Inside CCDC 24, the processes and forms

CCDC 24 is organized as a sequence of administrative processes. Each process begins with a short guideline explaining when it is used, followed by a checklist of required content and an example model form. Knowing the shape of the guide saves time during open-book practice and during the exam.

ProcessForms coveredWhere it lands on the ExAC
Prequalification of Contractors Contractor's Qualification Statement (CCDC 11, reproduced in Appendix A). Section 4, Bidding and Contract Negotiations objectives 9.3 and 9.4.
Financial Information Required of the Owner Project Financial Information (CCDC 12, reproduced in Appendix B). Section 4, Bidding and Contract Negotiations.
Payment Process Application for Payment, Schedule of Values and Work Performed, Certificate for Payment, Statutory Declarations (CCDC 9A and 9B in Appendix C), and Certificate of Substantial Performance. Section 4, Construction Phase Office Functions objectives 10.2 and 10.3.
Supplemental Instruction Process Supplemental Instruction Form. Section 4, Construction Phase Office Functions.
Change Process Proposed Change, Change Order, Change Directive, Summary of Changes, and a Combined Proposed Change and Change Order form. Section 4, Construction Phase Office Functions objectives 10.2 and 10.3.
Notification Process Notice Form (the standard format for written notices under the contract). Section 4, Construction Phase Office Functions and Field Functions.
Warranty Notification Warranty Notice and Product Warranty Notice forms. Section 4, Construction Phase Office Functions (project closeout).
Appendices CCDC 11, CCDC 12, CCDC 9A and 9B (standard forms reproduced in full), and the Definitions from CCDC 2 (2008). Reference material used across most Section 4 objectives.

The Change Process and the Payment Process carry the heaviest exam load. Read each as a connected sequence of forms, not as isolated documents.

Key CCDC 24 terms every ExAC candidate should know

CCDC 24 uses the defined terms from CCDC 2 (capitalized in the guide). Learn the ones below early so you spend exam time choosing the right form, not parsing the question.

TermWhat it means in CCDC 24
PrequalificationThe process of selecting bidders based on capacity, skill, and experience before issuing tender documents. Supported by CCDC 11.
Proposed ChangeA document the Consultant issues to the Contractor describing a possible change to the Work and requesting a price and schedule impact, without committing to proceed.
Change OrderA document signed by Owner, Consultant, and Contractor that authorizes a change in the Work and adjusts the Contract Price, Contract Time, or both.
Change DirectiveA written instruction from the Owner, prepared by the Consultant, directing the Contractor to proceed with a change in the Work before the cost or time impact has been agreed.
Supplemental InstructionA written instruction from the Consultant that clarifies the Contract Documents or orders minor adjustments without changing the Contract Price or Contract Time.
Application for PaymentThe Contractor's monthly request for payment, supported by an updated Schedule of Values and Statutory Declarations.
Certificate for PaymentThe Consultant's written confirmation that an Application for Payment is in order and that the certified amount is owed by the Owner.
Substantial PerformanceThe point in construction, defined by provincial lien legislation, at which the project is sufficiently complete to be used for its intended purpose. Certified using a model form in CCDC 24.
Statutory Declaration (CCDC 9A and 9B)A sworn statement by the Contractor (9A) or a Subcontractor (9B) confirming proper distribution of payment for previously certified work.
Notice in WritingA formal communication issued under the contract, with delivery and content rules set out in CCDC 2 and supported by the Notice Form in CCDC 24.
Warranty NoticeWritten notification to the Contractor of defective Work observed during the one-year warranty period that begins at Substantial Performance.
Project Financial Information (CCDC 12)Information the Owner provides to confirm that the funds required to pay for the Work are in place at the time of contract award.

How to study CCDC 24 for the ExAC

  • Read the introduction and the table of contents once so you can find any model form by name during a question.
  • Open CCDC 24 and CCDC 2 side by side. Trace each administrative process in CCDC 24 to the numbered General Conditions clause in CCDC 2 that triggers it.
  • Memorize the four change instruments (Proposed Change, Change Order, Change Directive, Supplemental Instruction). Know who signs, when each is issued, and which trigger a cost or schedule change.
  • Walk the payment chain end to end: Application for Payment, Schedule of Values, Statutory Declarations (CCDC 9A and 9B), Certificate for Payment, and Certificate of Substantial Performance.
  • Read CHOP Chapters 6.5, 6.6, and 6.8 in parallel. They place the CCDC 24 forms inside the architect's wider role on a project.
  • Drill scenario-based practice questions. Most ExAC questions on this document ask you to pick the right form for a situation, not to recite its fields.

ExAC sections CCDC 24 supports

Tips for Intern Architects reading CCDC 24

CCDC 24 is short, but it is dense. If you're early in your internship under the Internship in Architecture Program (IAP) or its provincial equivalent, the tips below help convert reading time into exam-day recall.

Tip 1, study the four change instruments as a set. Proposed Change, Change Order, Change Directive, and Supplemental Instruction are the most common scenario triggers in Section 4. Build a one-page chart showing who issues each, who signs each, and whether each adjusts the Contract Price or Contract Time. Carry it everywhere until the distinctions are automatic.

Tip 2, treat the payment process as one chain. Application for Payment, Schedule of Values, Statutory Declarations (9A and 9B), Certificate for Payment, and Certificate of Substantial Performance are not separate topics. Study them as the monthly cycle they actually are, and the exam questions get easier to read.

Tip 3, watch the edition gap. CCDC 24 was developed for CCDC 2 (2008), and Examitect's ExAC study plan lists CCDC 2 (2020). The forms remain in use, but some defined terms and clause numbers have moved. When you study a CCDC 24 form, confirm the related clause in the current CCDC 2 (2020) rather than assuming a one-to-one match.

Tip 4, pair CCDC 24 with CHOP. Examitect's study plan cites CHOP Chapters 6.5, 6.6, and 6.8 alongside CCDC 24 for every category. CHOP explains the architect's role in the process; CCDC 24 supplies the form. Reading them together is faster than reading them separately.

Tip 5, write your own one-page form summary. For each model form, write one page in your own words covering when it is used, who issues it, who signs it, and what it triggers. The act of writing the summary forces recall in a way that re-reading does not.

Tip 6, ask to see real forms at work. Many firms keep CCDC 24 model forms (or in-house adaptations) on every construction file. Ask your supervising architect to walk you through a recent Change Order or Certificate for Payment package. The conversation gives you a scenario you can anchor exam answers to.

Tip 7, recognize Notice in Writing as a formal step. Many Section 4 questions hinge on whether a written notice was required, who issued it, and within what time window. CCDC 24's Notice Form sits at the centre of that workflow; the answer often turns on the rules in CCDC 2 General Conditions Part 8.

Common ExAC scenarios where CCDC 24 is the answer

These question types come up across ExAC sittings. If you see one, your first instinct should be to ask "which CCDC 24 form fits this situation."

  • The Owner wants to add a small scope item and asks the architect to confirm cost impact before proceeding. Which instrument is appropriate, and what happens if the Contractor disagrees with the price?
  • The Owner instructs the Contractor to proceed with extra work before the price has been agreed. What document does the Consultant prepare, and how is the cost ultimately settled?
  • The Consultant needs to clarify a drawing discrepancy that does not change cost or time. Which form is correct, and what makes it different from a Change Order?
  • The Contractor's monthly Application for Payment is missing the latest Statutory Declaration. What is the Consultant's responsibility before issuing the Certificate for Payment?
  • The project reaches Substantial Performance. Which CCDC 24 model form is used to certify the date, and what does that date trigger under provincial lien legislation?
  • The Owner wants to prequalify three contractors before tender. Which form do bidders complete, and what categories of information does it gather?
  • A defect appears nine months after Substantial Performance. Which notice does the Consultant issue, and to whom?

Each scenario points back to a specific CCDC 24 model form. Knowing which form fits is most of the answer; the form's content is the rest.

How Examitect reinforces CCDC 24

Reading CCDC 24 is one half of the work. The other half is recognizing the right form under timed pressure. Examitect's question bank pulls heavily from CCDC 24 for Section 4 questions on bidding procedures and construction office functions. Each answer explanation cites the relevant CCDC 24 process and the related CCDC 2 clause, so you can re-read just the pages you need rather than the whole guide.

You also get scenario-based questions that put the CCDC 24 model forms into a real project context, full-length mock exams that mirror ExAC pacing, and free study notes for every section. Try a few sample questions first, then check pricing when you want the full bank.

CCDC 24 and ExAC FAQ

CCDC 24 (2016) is the Canadian Construction Documents Committee's Guide to Model Forms and Support Documents for use with CCDC 2. It explains the administrative processes referenced by CCDC 2 and provides model forms for prequalification, payment, supplemental instructions, change management, notifications, and warranty notices.

Yes, for parts of Section 4. Examitect's ExAC study plan lists CCDC 24 as a primary resource for two Bidding and Contract Negotiations objectives (procedures for awarding a contract; evaluating bids) and two Construction Phase Office Functions objectives (office-function tasks; use of administration forms).

Section 4 (Construction and practice). CCDC 24 supports Bidding and Contract Negotiations and Construction Phase Office Functions. It does not show up as a primary resource for any Section 1, 2, or 3 category on Examitect's study plan.

The current edition is CCDC 24 (2016), and that is the edition Examitect's ExAC study plan lists. It was developed for use with CCDC 2 (2008), but the model forms remain in use for projects administered under the newer CCDC 2 (2020) contract.

CCDC 2 is the standard stipulated price contract between owner and contractor. CCDC 24 is the guide that explains the administrative processes CCDC 2 refers to and provides example model forms for those processes, such as Application for Payment, Change Order, Change Directive, and Notice.

CCDC 11 is the Contractor's Qualification Statement, a standard form used to collect information on the capacity, skill, and experience of contractors bidding on a project. It is reproduced in Appendix A of CCDC 24 and supports the prequalification process.

CCDC 12 is the Project Financial Information standard form. The owner uses it to disclose that the funds to pay for the work are in place at the time of contract award. It is reproduced in Appendix B of CCDC 24.

CCDC 9A and 9B are the Statutory Declaration standard forms. CCDC 9A is the contractor's declaration of progress payment distribution; CCDC 9B is the subcontractor's declaration. Both are reproduced in Appendix C of CCDC 24 and support the payment process.
