Building Design & Inspection

Comprehensive building design and condition assessment. Grand Canada Engineering Limited (GCE) delivers rigorous technical assessments that protect structural integrity, improve energy efficiency, and resolve envelope failures.

Building Sciences & Structural Protection

Engineering Resilient Enclosures for Extreme Canadian Climates

The building envelope serves as the critical physical barrier between interior conditioned spaces and severe exterior climatic conditions. In Canada, building enclosures endure intense thermal fluctuations, driving rain, freeze-thaw cycles, and wind loads. Failures within exterior wall assemblies, air/vapor barriers, or fenestrations lead to uncontrolled moisture ingress, hidden mold growth, insulation degradation, and severe corrosion of structural anchors.

GCE Approach

GCE combines structural engineering principles with advanced building science to evaluate, diagnose, and remediate enclosure assemblies. Our engineering evaluations identify the root causes of envelope failure, delivering actionable repair specifications that restore air, water, and thermal performance.

Key Service Capabilities

Comprehensive Building Envelope Services

Cladding, Exterior Wall, Roofing & Window Wall Performance Evaluations

Physical reviews of exterior cladding systems, including precast concrete panels, brick masonry veneer, exterior insulation and finish systems (EIFS), metal composite panels, and siding assemblies.
Evaluation of glazed window wall, punch window, and curtain wall fenestrations to assess structural anchoring, gaskets, and thermal performance.
Condition reviews of commercial and multi-residential roofing assemblies, including inverted membranes, conventional built-up roofs (BUR), podium deck waterproofing, and parapet cap flashings.

Moisture Penetration, Thermal Bridging & Air Barrier Inspections

Comprehensive water infiltration testing and forensic leak tracing to determine exact paths of water ingress through roofs, walls, and foundation interfaces.
Air and vapor barrier continuity reviews to minimize uncontrolled air leakage, interior condensation risks, and interstitial envelope damage.
Thermal bridging assessments and infrared thermography evaluations to identify heat loss zones, missing insulation, and cold-weather moisture points.
Durability and lifecycle reporting, projecting remaining serviceable lifespans and preventative maintenance actions for property managers and building owners.

Remediation Design for Facades, Masonry Deterioration & Sealants

Targeted engineering drawings, specifications, and scopes of work for building envelope rehabilitation and capital renewal.
Remediation design for deteriorating exterior masonry, spalling brickwork, failing mortar joints, structural repointing, and replacement of corroded wall ties.
Engineering specifications for perimeter joint sealant rehabilitation, expansion joint replacement, and elastomeric wall coatings.
Modernization design to integrate high-performance continuous insulation and contemporary rainscreen cladding systems.
