Client: Mattamy Homes
Expertise: RB-19 Reporting
Mattamy Homes chose us for our proven ability to deliver value, innovative engineering solutions, and strong regulatory coordination.
Project Overview
Capacity Engineering is providing comprehensive RB-19 reporting and building envelope consulting for three timber-framed condominium buildings within Mattamy Homes’ Locale development. This multi-disciplinary engagement supports Mattamy’s commitment to high-quality construction, risk mitigation, and long-term durability.
Our involvement includes detailed RB-19 documentation for Tarion, envelope design and detailing in collaboration with Kohn Partnership Architects, and a suite of field tests to verify real-world performance. As one of Ottawa’s largest residential developers, Mattamy Homes relies on precise analysis and proactive engineering to ensure their buildings meet both regulatory requirements and long-term performance expectations.
Why Choose Capacity Engineering?
Mattamy Homes selected Capacity Engineering based on our proven track record in risk mitigation and our ability to deliver value-engineered, technically robust building envelope solutions.
We were chosen for our ability to provide:
- Reliable RB-19 reporting supported by accurate field data and clear, defensible analysis
- Value-engineered building envelope detailing that reduces the risk of moisture migration
- Collaborative design coordination with Kohn Partnership Architects to align performance with architectural intent
- High-quality field testing, including water penetration testing and guard rail load testing
- A proactive, detail-oriented approach that supports builders in meeting Tarion and code-compliance requirements
This combination of precision, dependability, and practical engineering judgment made Capacity Engineering the ideal partner for the Locale development.
Scope Of Work
- Completed full Tarion RB-19 reporting for three timber-framed condominium buildings
- Designed and detailed key building envelope elements to improve moisture protection and reduce long-term risk
- Collaborated closely with Kohn Partnership Architects to align envelope solutions with the architectural vision
- Performed fenestration water testing to validate window and glazing performance
- Conducted balcony guard rail load testing to confirm safety and structural reliability
Project Outcome
Capacity Engineering exceeded expectations by:
- Providing clear, comprehensive RB-19 documentation that supported both Mattamy and Tarion in understanding risk levels
- Identifying potential envelope vulnerabilities early, helping reduce costly warranty issues later in the building’s life
- Delivering solutions that balanced performance, cost, and constructibility—true value engineering in practice
- Maintaining responsive communication and consistent coordination across architectural, construction, and warranty teams
- Ensuring all testing was completed efficiently and to the highest standard, reducing delays and improving project confidence
Through a combination of technical depth, field expertise, and collaborative problem-solving, our team added measurable value to the Locale development.
