Building Theory Recognized for Structural Precast Concrete & BIM Engineering Excellence in BMO Centre Expansion

Building Theory is proud to celebrate the BMO Centre expansion’s recognition with the CISC Ontario Region Award of Excellence and the ENR Cultural Project Award of Merit. This achievement highlights our leadership in structural engineering services, advanced precast design, and integrated BIM architecture and engineering solutions. Building Theory’s technical mastery is on full display in the BMO Centre expansion, where we utilized cutting-edge digital workflows, architectural 3D modeling and Finite Element Method (FEM) analysis to solve complex structural and aesthetic challenges. Our team’s ability to deliver structural precast concrete solutions for irregular geometries and extreme wind loads ensured millimetre-level precision and preserved critical construction schedules.

The BMO Centre expansion in Calgary stands as a masterclass in emerging architectural ambition with engineering precision. As the largest convention centre in Western Canada, the facility now offers over 1 million sq. ft. of total space, featuring state-of-the-art exhibit halls, meeting rooms, and the nation’s second-largest ballroom.

Engineering Challenges & Structural Solutions:

Building Theory played a pivotal role as the Precast Concrete Engineer and Modeller, delivering advanced precast detailing services and overcoming significant technical challenges created by the building's unique geometry:

• Custom Load Engineering: Each of the 150+ unique precast panels was developed using precise precast panel design methodologies to withstand site-specific wind loads determined through rigorous wind tunnel testing.
• Innovative Connections: To navigate irregular steel framing, the team utilized Finite Element Method (FEM) analysis to design custom steel brackets. This approach ensured seamless integration of structural precast concrete elements without altering the primary structural steel, preserving the project schedule.
• Complex Geometry: The grand entrance features 3D-modelled precast coping elements that twist and slope along curved profiles, achieved through meticulous digital coordination.

Technology-Driven BIM & Engineering Precision

The project's success was driven by a fully integrated BIM architecture and engineering workflow. Using Tekla Structures and proprietary in-house engineering tools, Building Theory ran complex simulations to validate designs against exacting tolerances. This high-level coordination within a fully integrated BIM environment (Autodesk BIM 360) ensured millimetre-level accuracy between the precast components and the steel structure.

Our BIM and architecture approach enabled:

• Real-time collaboration across project teams
• Advanced simulation and design validation
• Accurate architectural 3D modeling and detailing
• Millimetre-level alignment between precast and structural systems

This digital-first methodology ensured precision, reduced rework, and enhanced overall construction efficiency.

Award-Winning Excellence

The expansion’s seamless blend of aesthetic beauty—defined by its custom thin-brick "Norman bond" finish—and technical mastery has earned it prestigious recognition, including:

• ENR Cultural Project Award of Merit
• CISC Ontario Region Award of Excellence
• CEA Award of Excellence

This award-winning project reinforces Building Theory’s expertise in structural engineering, precast design, and BIM solutions showcasing what is possible when engineering innovation meets visionary architectural design.
