Detailed guides and case studies on structural feasibility and land-use compliance under the National Building Code of Canada.
This article walks through the full seismic load path for a 10-storey steel moment frame building. It covers diaphragm forces, collector beams, and connection design per NBC 2020. The guide includes a worked example with real column and beam sizes, so engineers can compare their own assumptions against a documented case.
Read full articleThis article explains how to classify mixed-use occupancies under NBC Part 3 and apply the correct fire separation ratings. It uses a three-storey building with ground-floor retail and two residential floors as the base case. The text covers sprinkler trade-offs, exit stair pressurization, and common classification mistakes that delay permit approval.
Read full articleThis article examines how municipal zoning bylaws interact with NBC requirements for infill developments on narrow lots. It covers minimum setback distances, building height limits, and the impact on fire access routes. The discussion includes a real scenario from a Toronto laneway project where zoning and code requirements conflicted, and how the conflict was resolved.

We evaluate the proposed building’s gravity and lateral load paths, foundation capacity, and seismic resistance against NBC Part 4 and Part 9 requirements. The study identifies code gaps early, so you can adjust column grids, floor systems, or bracing before detailed design begins.
We review the municipal zoning bylaw alongside NBC occupancy classifications, fire separations, and accessibility standards. The process includes checking permitted uses, setback distances, floor area ratios, and parking requirements. Any conflicts are documented with a clear path to resolution.
Not always, but it reduces risk significantly. Many municipalities in Canada expect a preliminary code review for projects with unusual structural systems, mixed occupancies, or sites in seismic zones. A study can prevent costly redesigns after permit submission.
We flag each non-compliance item and propose alternative solutions — like increasing fire-resistance ratings, adjusting egress widths, or adding structural bracing. Our reports include specific code references so your design team can implement fixes without guesswork.
For a mid-rise commercial building, expect two to four weeks. The timeline depends on the complexity of the structural system, the number of occupancy types, and how quickly we receive architectural drawings and geotechnical reports.
Scope and interpretation notes
Our structural feasibility studies address gravity and lateral load paths, foundation capacity, and seismic force resistance as prescribed by Division B of the National Building Code of Canada. We do not include geotechnical borehole interpretation unless explicitly commissioned as a separate scope item.
No. Each review cross-references municipal zoning with NBC occupancy classifications, fire separation distances, and accessibility requirements under Section 3.8. The final deliverable identifies conflicts between local land-use permissions and code-mandated building attributes.
Heritage retrofits follow the NBC’s alternative solution provisions (Division C, Clause 1.2.1.1.). We prioritise existing material assessment—masonry, timber, steel—before proposing discreet structural upgrades. The heritage designation does not override life-safety requirements; any variance must be accepted by the authority having jurisdiction.
Our reports serve as professional opinions prepared by licensed engineers registered in the province of the project. They are intended to support permit applications but do not guarantee approval. Final acceptance rests with the local building official and any required peer review.
A standard study excludes cost estimation, construction scheduling, environmental site assessment, and detailed energy modelling. These can be added as separate work packages. Our scope is strictly limited to structural and land-use code compliance under the NBC.
