CHING, Building Construction Illustrated for the ExAC

Building Construction Illustrated, by Francis D.K. Ching, is the visual reference for how a Canadian building actually goes together. For the Examination for Architects in Canada (ExAC), Examitect treats the 7th Edition as a core study reference for most categories in Section 1 (Design and analysis) and Section 3 (Sustainability and final project). The official ExAC Preparation Guide names only four primary reference documents, CHOP, the IAP, NBC 2020 and NECB 2020, and does not name Building Construction Illustrated.

Why CHING matters for the ExAC

CHING is the visual spine of Examitect's ExAC reading list. Examitect's study plan treats Building Construction Illustrated (7th Edition) as a core reference for almost every Section 1 category outside of programming, and for almost every Section 3 category. The official Preparation Guide names only CHOP, the IAP, NBC 2020 and NECB 2020 as primary reference documents, and publishes no per-category reference mapping. When a question asks how a wall is built, how a slab on grade handles moisture, or what controls the difference between a curtain wall and a window wall, the answer almost always traces back to a CHING chapter.

The book also teaches you to read assembly diagrams under pressure. ExAC questions in Sections 1 and 3 often include cropped drawings, callouts, or material lists, and candidates who have spent time inside CHING recognize the patterns immediately. Reading CHING closely is one of the highest-yield study activities for those two sections.

If you only had time to study one assemblies-and-building-science reference before the ExAC, CHING would be it.

How to study CHING for the ExAC

  • Skim the whole book once so you know what lives where, then plan a deeper read on Chapters 3 through 8 (foundations, floors, walls, roofs, moisture and thermal protection, doors and windows).
  • Study assemblies by section, not by page. For each chapter, pick the two or three diagrams that explain the assembly logic and re-draw them by hand. The act of redrawing forces understanding.
  • Pair CHING with the NBC, especially Part 5 (environmental separation) and Part 9 (small buildings). The CHING diagrams make the code provisions concrete.
  • Tab the high-yield diagrams: rainscreen wall, vapour retarder placement, typical foundation section, roof drainage, window flashing, and the wall-to-roof intersection.
  • Test recall with scenario-based practice questions. CHING content sticks faster when you apply it to a project situation than when you re-read passages.
  • Anchor every chapter to a real assembly you have seen on a job or a site visit. Diagrams stick when they have a story.

ExAC sections CHING supports

  1. Section 1

    CHING is a core Examitect reference for almost every Section 1 category outside of programming.

  2. Section 3

    CHING is a core Examitect reference for almost every Section 3 category. This is where it carries the most weight.

Twelve Chapters inside CHING

The 7th Edition is organized into twelve chapters and a reference appendix. The chapter and sub-section titles below follow the standard 7th Edition structure; if you have the book open, your headings should match. Because CHING is a printed reference rather than a web publication, the sub-section labels are shown as tags for orientation, not as links.

Key CHING terms every ExAC candidate should know

CHING introduces vocabulary the ExAC reuses without redefining. Learn these terms early so you spend exam time choosing the answer, not parsing the question.

TermWhat it means in CHINGWhere to read in CHING
Bearing wall A wall that supports vertical load from the structure above in addition to its own weight. Contrasted with a non-bearing partition.
  • Chapter 5: Wall Systems
Curtain wall A non-bearing exterior wall hung from the building structure, designed to resist wind and weather while carrying only its own weight.
  • Chapter 7: Curtain Walls
  • Chapter 8: Glazed Curtain Walls
Spread footing A widened base at the bottom of a foundation that distributes load over a larger area of soil. The most common shallow foundation type for low- to mid-rise construction in Canada.
  • Chapter 3: Foundation Systems
Slab on grade A concrete floor cast directly on prepared ground rather than on a structural frame. Requires careful detailing for moisture, insulation, and frost protection.
  • Chapter 3: Foundation Systems
  • Chapter 7: Moisture & Thermal
Platform framing Wood-frame construction where each storey is built as a platform on top of the one below. The dominant residential framing method in Canada.
  • Chapter 4: Floor Systems
  • Chapter 5: Wall Systems
Air barrier A continuous material or system that resists air leakage through the building envelope. Required by the NBC and a recurring topic in Part 5 questions.
  • Chapter 7: Moisture & Thermal
Vapour retarder A material that slows the diffusion of water vapour through an assembly. Placement depends on climate; in most of Canada it sits on the warm side of the insulation.
  • Chapter 7: Moisture & Thermal
Rainscreen A cladding strategy that places a drained and vented cavity behind the exterior face so any water that gets past the cladding can drain and dry.
  • Chapter 7: Rainscreen Wall Systems
Thermal bridge A path through an assembly with lower thermal resistance than the surrounding insulation, such as a steel stud or a balcony slab. A major focus of current NECB-driven design.
  • Chapter 7: Moisture & Thermal
Flashing Sheet material installed to direct water away from joints, openings, and terminations in the building envelope.
  • Chapter 7: Moisture & Thermal
  • Chapter 8: Doors & Windows
Drainage plane The continuous surface in a wall assembly that sheds liquid water to the exterior, typically the back face of the cladding or the face of the sheathing membrane.
  • Chapter 7: Water-Resistive Barriers
Glazing The transparent or translucent part of a window, door, or curtain wall, plus the framing and sealants that hold it in place.
  • Chapter 8: Doors & Windows

Tips for Intern Architects reading CHING

CHING was written for someone learning the craft, which makes it friendlier to read than a code book. The catch is that the diagrams pack a lot of information per page. Here is how to read CHING without skimming past the parts that show up on the exam.

Tip 1, read with a pencil. Annotate every diagram you study. Circle the air barrier, trace the load path, mark the warm side of the insulation. Passive reading does not stick. The reason CHING is a classroom favourite is that it rewards active note-taking.

Tip 2, pair every chapter with the NBC. When you read Chapter 7 on moisture and thermal protection, open NBC Part 5 alongside it. When you read Chapter 3 on foundations, open NBC Part 9. The diagrams in CHING make the code provisions click, and the code provisions tell you which CHING details actually meet Canadian requirements.

Tip 3, focus on the wall section. Most ExAC envelope questions live or die on whether you can read a wall section confidently. Make sure you can identify, from the outside in, every layer of a typical rainscreen wall, and where the air, water, vapour, and thermal control layers sit.

Tip 4, redraw the top five details by hand. Typical foundation, typical exterior wall, typical low-slope roof, typical window head and sill, and a wall-to-roof junction. Redrawing them once will do more for retention than re-reading the chapter three times.

Tip 5, tie Chapter 11 to your project's consultants. When you read the mechanical and electrical chapter, picture the latest mechanical drawing set you saw at the office. Most Section 1 engineering coordination questions are about knowing which decisions are the architect's and which are the consultant's.

Tip 6, do not skip the Appendix. The Appendix carries human dimensions, building live loads and material weights, means of egress, fire-rated construction, acoustics, graphic material symbols, CSI MasterFormat and Uniformat II. There is no cost data in it: A.23 Uniformat II is an elemental classification framework used to organize estimates, not a source of prices. For cost data go to Hanscomb Yardsticks for Costing and RSMeans, and to CHOP 4.2 for the architect's role in cost planning and control. The Appendix is short, scannable, and high-yield for the Section 3 documentation questions.

Tip 7, track gaps against your IAP experience. If you read a chapter and realize you have never seen that assembly built, flag it for your supervising architect. The Internship in Architecture Program (IAP) experience categories overlap heavily with the CHING chapters, and a targeted project assignment can close a study gap and an experience gap at once.

Common ExAC scenarios where CHING is the answer

These question types come up across ExAC sittings. If you see one, your first instinct should be to picture the relevant CHING diagram.

  • A wall assembly is failing inspection because condensation is forming on the interior face of the sheathing. Where is the vapour retarder likely misplaced?
  • A sloped site requires a stepped foundation. Which CHING principle determines the spacing and depth of each step?
  • A curtain wall is being chosen over a window wall for a six-storey office. What does that decision change about load path, anchorage, and floor-to-floor coordination?
  • The architect must choose between platform framing and a hybrid wood-and-steel solution for a small mixed-use building. What trade-offs apply?
  • A flat roof drains poorly after a year in service. Which envelope continuity issue is the most likely cause, and which CHING chapter covers it?
  • A window head detail leaks during a wind-driven rain event. What is missing from the flashing sequence?
  • A schematic design needs an early estimate of building area, cost, and structural depth. Which CHING chapters and Appendix references support that pricing exercise?

Each scenario traces back to a CHING chapter. Chapters 3 through 8 (foundations through doors and windows) carry the most weight, with Chapter 1 (site), Chapter 11 (systems), and the Appendix (accessibility, means of egress, acoustics, drawing standards) close behind.

How CHING compares to other ExAC references

CHING is the assemblies-and-building-science spine of Examitect's ExAC reading list, but it does not stand alone. Use this comparison to decide what to read for which kind of question.

ReferenceWhat it's forHow CHING relates
CHINGThe visual reference for how Canadian buildings are assembled: site, foundations, structure, envelope, openings, finishes, and systems.The reference standard for building-science and assemblies content on the ExAC.
CHOPThe full landscape of Canadian architectural practice: profession, business, project delivery, and every project phase.Different jobs. CHOP is how a project runs; CHING is how a wall is built. Both are tested, in different sections.
NBC 2020The national model building code: technical compliance rules.CHING shows how assemblies are commonly built; the NBC sets what is required. Reading them together accelerates Part 5 and Part 9 study.
NECBThe national model energy code for buildings.CHING shows envelope detailing, including thermal bridging and continuity of insulation. The NECB sets the performance targets.
RSMeans and YardsticksConstruction cost data for early-stage estimating.CHING explains the assemblies behind the cost lines. Once you understand a wall section, the unit prices stop being abstract.
Architectural Graphic StandardsComprehensive American graphic standards covering materials, accessibility, and assemblies.Graphic Standards goes deeper on tabular data and code-related geometry. CHING is faster for assembly logic and reads better cover-to-cover.
Canadian Wood-Frame House ConstructionA Canadian guide to NBC Part 9 wood-frame residential construction.Pairs well with CHING for Part 9 detailing questions; CHING explains the principles, CWFHC gives the Canadian residential specifics.

How Examitect reinforces CHING

Reading CHING is half the work. The other half is recognizing the content under pressure on a timed exam. Examitect's question bank draws heavily from CHING for Section 1 design questions and Section 3 building-science questions. Each answer explanation points back to the specific CHING chapter and page range, so you can re-read just the pages you need rather than the whole book.

You also get scenario-based questions that put CHING's diagrams 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.

FAQ

CHING FAQ

Building Construction Illustrated, by Francis D.K. Ching, is a visual reference covering site work, foundations, framing, envelope assemblies, doors and windows, finishes, mechanical and electrical systems, and materials. Examitect treats the 7th Edition as a core study reference for most categories in Section 1 (Design and analysis) and Section 3 (Sustainability and final project). The official ExAC Preparation Guide does not name the book: its four primary reference documents are CHOP, the IAP, NBC 2020 and NECB 2020.

Not in the official sense. The ExAC Preparation Guide names four primary reference documents: CHOP, the IAP, NBC 2020 and NECB 2020. Building Construction Illustrated is not among them, and it is not named in the guide at all. Examitect still treats it as a core study reference for site analysis, engineering systems, cost management, schematic design, design development, materials, building science, assemblies and detailing, construction documents, specifications, document coordination, and sustainable design literacy.

Section 1 (Design and analysis) and Section 3 (Sustainability and final project). Examitect does not use CHING for Section 2 (Codes), which is covered by the NBC and NECB, or for Section 4 (Construction and practice), which is covered by CHOP and the CCDC and RAIC contract documents.

Examitect teaches from the 7th Edition (Wiley, 2025). The ExAC Preparation Guide does not specify an edition, because it does not name Building Construction Illustrated at all. Earlier editions cover similar material, but their page references will not match.

Skim once for the shape of the book, then study Chapters 3 through 8 in depth. Tab the assembly diagrams you keep coming back to, pair CHING with the relevant NBC Part 5 and Part 9 provisions, and test recall with scenario-based practice questions.

CHING is how a wall is built. CHOP is how a project runs. CHING covers the physical assemblies, materials, and building science behind a building; CHOP covers the architect's practice, contracts, project phases, and site administration. The ExAC tests both, in different sections.

No. Focus on the diagrams that explain assembly logic: how loads travel through a foundation, how a rainscreen wall sheds water, how a vapour retarder is placed for the climate, how a roof drains, and how openings are flashed. ExAC questions test principles, not isolated facts.

CHING shows how assemblies are typically built; the NBC sets what is required. Reading them together is the fastest way to internalize Part 5 (envelope) and Part 9 (small buildings). CHING is also core Examitect reading for the document coordination and code compliance category in Section 3.
