Guidelines Nearing Completion for Encapsulated Mass Timber Construction up to 12 Storeys

Posted on October 7, 2020

Engineers and Geoscientists BC and the Architectural Institute of British Columbia (AIBC), along with the Government of BC, are developing professional practice guidelines in support of the legislative changes in BC which allow construction of mass timber buildings up to 12 storeys. The guidelines are nearing completion, and Engineers and Geoscientists BC and AIBC are providing this opportunity for industry input.

The Joint Professional Practice Guidelines - Encapsulated Mass Timber Construction up to 12 Storeys are being developed in response to the new 2018 BC Building Code classifications of building size and construction relative to occupancy: Article 3.2.2.48EMTC. Group C, up to 12 storeys, Sprinklered, and Article 3.2.2.57EMTC. Group D, up to 12 storeys, Sprinklered. The new guidelines address the standard of professional practice for architects and engineering professionals when providing professional services related to encapsulated mass timber construction up to 12 storeys. The guidelines cover minimum qualifications, professional practice, roles and responsibilities, and quality assurance for encapsulated mass timber construction projects. These guidelines 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.

The new guidelines will support the Government of BC’s May 2019 announcement that it is proceeding with a regulation to allow construction of mass timber buildings up to 12 storeys. The new provisions are expected to be introduced in the National Building Code 2020, but have been adopted in BC in advance of the national changes.

Engineers and Geoscientists BC registrants who are interested in commenting on the latest draft of the guidelines can contact Allison DenToom at [email protected]. Comments are due by October 16, 2020.
