Mass Timber Design Guide CrossLam® CLT | GlulamPLUS® | Mass Timber Building Systems U.S. VERSION Penticton Lakeside Resort, Penticton, BC, Canada Mica Heli-Ski Lodge, Mica, BC, Canada Beautifully engineered to change an entire industry. At Structurlam, it’s been our goal for more than 50 years to innovate and push the boundaries of our industry in order to create new limits of what it means to build with wood. Through our experience in bringing buildings to life, we’ve been proud to be part of developing and producing structures in exciting and efficient new ways. In fact, as the industry moved toward evolved, Structurlam has pioneered the use concrete and steel in commercial buildings, of cutting-edge technology and systems to we stayed true to ourselves. We understood bring your project from concept to reality. the advantages of building with wood and of From prefabrication of structural elements to laminating lumber into beams that could be erection on-site, BIM modeling permits the use used in larger structures. We embraced new of mass timber to be highly precise, efficient technology, such as 3D modeling and robotic and cost competitive. machinery, to fabricate complete mass timber By working with us, you’re always assured packages. This allowed us to introduce wood engineering expertise and design efficiency that into buildings where it was never considered reduces time and cost on-site. No job is too in the past. simple or too complex, and we’ll always work to The result is an array of high-performance mass help you build whatever you dream. So go out timber structures that are environmentally there and be creative. friendly, cost-effective and aesthetically stunning. As the mass timber industry has 2 INTRODUCTION | U.S. Mass Timber Design Guide U.S. Mass Timber Design Guide | INTRODUCTION 3 Commercial Transportation Educational Mission Office, Kelowna, BC, Canada Fort McMurray Airport, F. McMurray, AB, Canada Okanagan College, Kelowna, BC, Canada Multi-Family Industrial Virtuoso, Vancouver, BC, Canada BC Passive House Factory, Pemberton, BC, Canada The Structurlam Advantage Structurlam is more than a fabricator of the highest-quality CNC machines for fabrication. Finally, our 3D model is used engineered wood products. We operate at the front lines of to develop a material list for efficient purchasing of steel and innovation in mass timber design, engineering, 3D modeling hardware components. Loading diagrams are then created and precision manufacturing. One of the biggest benefits with to optimize freight and assembly drawings are produced to Winner of 2016 Governor General’s Award for Architecture mass timber buildings as compared to other types of structures provide instruction for quick and efficient installation. is the ability to prefabricate the entire structure. This saves precious time and money on-site because the installation Design teams who leverage our fabrication services receive Healthcare process becomes more efficient. Since the 1990s, Structurlam aesthetically appealing buildings with optimized structural Ronald McDonald House, Vancouver, BC, Canada has been leveraging state-of-the-art 3D modeling software performance and rapid assembly; where every piece fits to virtually construct each building before it is produced. Our and no detail is missed. Because mass timber structures are team begins with the two-dimensional drawings and creates relatively new, many of our first-time customers come to a 3D model. This model includes all of our components: us with a concrete building already designed and ask us to GlulamPLUS®, CrossLam® CLT, steel connections and associated offer an option with Structurlam Mass Timber solutions using hardware. Virtual construction allows our highly-trained GlulamPLUS® and CrossLam® CLT. While this is possible, it is detailers to detect potential problems and prevent issues in always better to design with the structural system of choice. the field. The work to build the model often takes three times With CrossLam® CLT, optimum sizes are 7'10.5" x 40' and longer than the actual time to produce the components, but 9'10.5" x 40'. This is the best way to ensure an efficient it’s necessary for a smooth assembly process on-site. design, optimal panel spans and layout and the most cost- effective structure. Once the design work is complete, the model is used to create manufacturing lists for CrossLam® CLT and GlulamPLUS®.
