NBC Part 4 structural provisions, load types, referenced design standards, and the architect's coordination role with the structural engineer.
Every Structural Coordination practice question links back to the reference you'd use in the real exam.
National Building Code of Canada
Structural reference
Seismic reference
Examitect drills each of these areas. The list below maps to the question categories you'll see inside.
Why this topic matters. Structural coordination questions test whether you understand load paths well enough to coordinate with the engineer. Examiners reward candidates who know the difference between NBC structural requirements and architectural decisions.
Architects don't design structure, but they coordinate it. That means knowing where loads come from (gravity, lateral, environmental), how they travel through the structure to the foundation, and which CSA standards the NBC references for design. Part 4 covers Part 3 buildings; Part 9 has its own simplified structural provisions.
Section 4.1 sets out structural loads (dead, live, snow, wind, seismic) and references design methodologies. Section 4.3 references material-specific design standards: CSA O86 (wood), A23.3 (concrete), S16 (steel), and S304 (masonry). The architect's role is coordination, not design.
Dead loads are permanent. Live loads vary by occupancy (e.g., 1.9 kPa for residential, 2.4 kPa for office, 4.8 kPa for assembly). Snow loads come from Appendix C. Wind loads come from Appendix C. Seismic loads use Section 4.1.8 with site coefficients. Importance categories run from Low to Post-Disaster.
Watch for distractors that have the architect specifying member sizes or load paths. The structural engineer designs. The architect coordinates: confirms the grid, accommodates structure in the design, identifies conflicts. Alternative solutions for structural equivalency use Division A, 1.2.1.1.

Estimated study time. Most candidates spend 8 to 12 hours on Structural Coordination. Adjust up if you don't see this work in your day job, down if you do.

No. The architect coordinates with the structural engineer. The engineer designs and stamps the structural drawings.
Dead loads from materials, live loads from occupancy (Table 4.1.5.3), snow and wind from Appendix C, seismic from Section 4.1.8.
Part 9 Sections 9.3 through 9.23 cover structure for small buildings. It's prescriptive (sizes from tables) rather than engineered design.
8 to 12 hours. The goal is fluency in the engineer's language, not design competence.
