The Engineers and Geoscientists BC and AIBC Joint Professional Practice Guidelines - Encapsulated Mass Timber Construction up to 12 Storeys were developed in response to BC Government changes to the BC Building Code and the BC Fire Code to permit construction of mass timber buildings up to 12 storeys based on the new classifications of building size and construction relative to occupancy: Article 188.8.131.52EMTC. Group C, up to 12 storeys, Sprinklered, and Article 184.108.40.206EMTC. Group D, up to 12 storeys, Sprinklered. Sentence 220.127.116.11.(7), Division A, lists the local authorities within which the EMTC provisions apply.
Please note: An overview of the guidelines was presented in a webinar on September 21, 2021 and is available in the Online Store. Attendees of this online workshop are strongly encouraged to view the overview webinar and read the guidelines prior to attending.
The guidelines cover minimum qualifications, professional practice, roles and responsibilities, and quality assurance for encapsulated mass timber construction (EMTC) projects. They also identify issues to be taken into consideration, provide sources of information, and, in some instances, design options when providing architectural, building enclosure, fire protection, acoustical, structural, mechanical, and electrical design services for EMTC buildings up to 12 storeys, or parts of such buildings.
The discipline-specific segments will focus on the following:
- The architectural session will cover approaches to managing integrated systems; changes to systems, structural member sizes and grids, and assemblies; and prefabrication.
- The enclosure session will cover how the EMTC provisions impact the design, detailing, material selection, and construction of building enclosures; moisture control requirements and strategies to protect the mass timber during construction; and considerations for prefabricated enclosure elements.
- The fire protection section will cover common misconceptions on the calculation of char and rules for exposed mass timber; firestopping and concealed spaces, specifically around connections; and construction fire safety.
- The acoustics section will cover the importance of establishing the design intent and targets early in the project; assembly/layering requirements; and interior separations and noise isolation, including the various transmission paths.
- The structural section will elaborate on the char calculations and concepts introduced in the fire protection section and will cover considerations and coordination required to determine appropriate gravity systems; limitations of shearwalls and code compliant lateral systems; and connections and services routing.
- The mechanical section will cover fire protection and general considerations for running services, especially those containing water, in concealed spaces; structural and acoustical considerations for services routing; and the requirement for encapsulation during construction as it relates to installation and testing of services.
- The electrical section will cover the Canadian Electrical Code requirements; general design considerations including services routing and coordination with other professionals; and construction sequencing as it relates to installation and testing.

Principal, Read Jones Christoffersen Ltd.
A respected champion for innovations in wood design and increases in the use of mass timber systems, Grants work has pushed the height limits of traditional wood framed structures both in practice and through code development. He also leads highrise and developer oriented projects, considering costs and buildability to develop the right solution to maximize pro formas and deliver architectural vision. While his projects are often complex in nature, he brings simplicity to design, seeking practical, effective solutions. His practical sense comes from his life lessons working with wood and concrete on personal projects.
Grant graduated from the University of Calgary in 1989 and completed his master’s at McGill University. He is a member of the BC Advisory Group on Advanced Wood Design Solutions, co-authoring guidelines that support code changes revising the 4-storey limit to 6-storey both in the BCBC and NBCC. He has authored several guides, given numerous presentations, and provided support for Michael Greens Tall Wood Study, and FP Innovations CLT Guideline and Tall Wood Guideline. Grant is now working with the AIBC and Engineers and Geoscientists BC on a guide for Encapsulated Mass Timber Structures moving to 12 storeys. His involvement with tall high-rise structures up to 50 storeys and long history with wood structures made him a natural to push the status quo far beyond 4-storeys. Grant also helped develop Engineers and Geoscientists BC’s Practice Guidelines for Structural, Fire Protection and Building Envelope Professional Engineering Services for 5- and 6-storey wood frame buildings.
