Sustainable Structural Engineering & Advanced Design

Petra delivers engineered structural solutions designed to maximize asset longevity while withstanding Canada’s demanding climate and structural loads. From commercial developments across Greater Montreal, the Capitale-Nationale, and the Greater Toronto Area to multi-provincial assets in Nova Scotia, Alberta, and British Columbia, our structural engineers combine finite element analysis (FEA) with practical construction methods. We prioritize resilience and sustainability by integrating innovative, corrosion-resistant materials—such as Glass Fiber Reinforced Polymer (GFRP) rebar—alongside mass timber, structural steel, reinforced concrete, and masonry systems. Every design is engineered to exceed OBC, Quebec Building Code, and NBC performance targets—delivering low-carbon, longer-lasting structures built for the future, while maintaining strict cost-efficiency to respect your project budget without ever compromising structural safety.

Core Capabilities

  • Complete structural engineering packages for commercial, industrial, institutional, and multi-unit residential developments.

  • Stamped engineering plans for wall removals, floor additions, change-of-use conversions, and industrial mezzanine retrofits.

  • Precise structural calculations engineered for heavy Canadian ground snow loads, wind uplift, thermal expansion, and ice accumulation.

  • Comprehensive structural field visits, shop drawing reviews, and municipal site compliance certificates to ensure construction matches stamped engineering plans.

Detailed structural engineering drawings and building code permit plans

Engineering Deliverables

Complete stamped structural drawing packages, structural calculation binders, material specifications, and field review certificates required for building permit applications across Quebec and Ontario municipalities.
