The benefits of a positive acoustic experience extend beyond traditional classrooms. Their relevance can be heard in gyms, aquatic centres, auditoriums, cafeterias, offices, theatres, band rehearsal rooms, recording and broadcast studios, fabrication shops, media centres, and more.

The National Research Council Canada (NRC) is working to integrate climate resiliency into building and infrastructure design, guides, and codes. In this article, the authors present a framework for climate-resilient design of commercial roofs that will become part of the Canadian Standards Association (CSA) A123.26, Performance Requirements for Climate Resilience of Low Slope Membrane Roofing Systems.

The North American steel industry has developed necessary tools to meet code requirements for acoustic separation in cold-formed steel frame construction in response to changes in the National Building Code of Canada (NBC). The code now considers additional paths for sound waves, including flanking transmissions through shared ceilings and floors.
|
The acoustic requirements in the 2015 National Building Code of Canada (NBC) have changed. As a consequence, designers and architects need to pay more attention to sound transmission via the junctions between floors and walls.

As we move toward taller timber buildings, fire and acoustics considerations for dwelling units above dwelling units is increasingly important. This article shares the results of National Research Council of Canada testing of various sound control assemblies to comply with new National Building Code of Canada (NBC) requirements. The results are beneficial for architects and specifiers working on wood-framed, multifamily structures.

You are probably thinking, “Oh great, another article about codes.” However, it is always surprising so many in the design/construction industry do not fully understand how building codes work (nationally and provincially), how they are developed, and how they impact individual firms.

The Canadian Commission on Building and Fire Codes (CCBFC) has invited design/construction professionals and other interested parties to participate in its public review of proposed changes to the National Building Code of Canada 2015 (NBC), National Fire Code of Canada 2015 (NFC), and National Plumbing Code of Canada 2015 (NPC). The review will run on Codes Canada website until January 2, 2018.

It may seem pressure-treated wood has been around forever. Some may view it as an old product with very little, if any, innovation. While the former statement may have some element of truth, the latter is far from accurate. Treated wood products, in some form or fashion, have been around for millenia.

Annex D of Canadian Standards Association (CSA) A23.3-04, Design of Concrete Structures, introduces a new and comprehensive limit states design (LSD) procedure for determining factored tension and shear resistance of both cast-in-place (CIP) anchors and pre-qualified post-installed mechanical anchors installed in cracked and uncracked concrete.
