Early Mass Timber Collaboration: A Journey from Design Assists Pre-Construction through Construction
Course Overview In this session attendees will be taken through the evolution of the mass timber structure design for the Sam Centre at the Calgary Stampede. We will explore the varied forms of collaboration from design and pre-construction through construction to completion. During the talk the value of collaboration will be examined from a design assist trade to the early onboarding of a mass timber erector, to the engagement of a mass timber specialists examining topics from erection tolerances to moisture and construction protection, to storage procedures, to fire retardant impregnation, and the aesthetic and performance outcome of each. Particular attention will be paid to how the process of collaboration at the various stages aided the design and successful execution of the mass timber connection details. A tour of the project could also be offered given its proximity to the conference. The Sam Centre is a year-round immersive experience that brings the ‘world of the Calgary Stampede’ – past, present and future – to life through technology, story-making, and Western hospitality. The use of Mass timber was a key strategy in connecting to the history of the Stampede and its historic structures. Sam Centre is a linear volume characterized by a large horizontal pitched roof. The structure uses a repetitive hybrid steel frame with exposed mass timber beams and a Nail Laminated Timber Roof Deck, adding warmth to the interior and creating a distinct profile offering a modern yet durable nod to traditional barn construction. Creating deep overhanging soffits which mitigate heating and cooling loads, the roof also evokes the welcoming verandahs of traditional Alberta architecture. Learning Objectives Learn how design assist supported the design of the mass timber connections and how those details would be built to ensure the structure was built efficiently and effectively. Learn about the importance of bringing on a mass timber erector early in the design process to ensure that the construction system and any tolerances required are correctly captured in drawings. Understand the value of a collaborative approach between design team, consultants, trades, and building science team to ensure all facets of mass timber construction are noted across project phases.

Unlocking Affordable Timber Innovations in Structure, Prefabrication, and Code
Course Overview Bond Tower is a 7-storey mixed-use prototype that asks a critical question: how can mass timber be made cost-effective in the Prairies, where supply chains are limited, demand is low, and timber construction is often reserved for flagship projects. Funded by the Green Construction through Wood Program from Natural Resources Canada, the project develops both prototypes and a built demonstration to advance affordable timber solutions in a region underserved by the current market. The design leverages nail-laminated timber (NLT) as its primary system, applied in diagrid trusses, floor assemblies, and shear walls. NLT presents a cost-effective alternative to other manufactured products and provides great versatility due to its custom nature. Lateral and gravity-induced forces are carried by a diagrid timber truss fabricated from readily available dimensional lumber and using simple mechanical fasteners. Floor assemblies comprised of NLT are constructed without a concrete topping or proprietary sound attenuation systems, reducing both cost and embodied carbon. Prefabricated wall panels, stairs, and modular service pods further minimize waste and construction time. Another challenge lies in building code classification. Currently, all structures above six storeys are deemed high-rise, requiring costly and difficult to achieve [in timber] two-hour fire-resistance ratings and fire-safety systems. The Bond Tower design team, working with code consultants, is developing an alternative solution that leverages the inherent 1.25-hour FRR of NLT floor assemblies. This approach suggests a pathway toward a new mid-rise category, making timber projects of seven or eight storeys more financially viable. Alongside a single-stair configuration, which can increase efficiency by reducing non-rentable floor area, these strategies point to a replicable model for affordable timber construction across Canada. Learning Objectives Learn how NLT and prefabrication strategies can reduce cost, waste, and construction time, making timber more feasible in the Prairies. Explore structural detailing approaches that simplify connections and reduce cost, while addressing fire, durability, and acoustic performance in timber design. Examine how alternative solutions can improve the financial feasibility of 6–8 storey timber projects and support broader code updates across Canada.

A Zero Carbon Hybrid Wood Supertall Future
Course Overview With buildings generating 40% of global carbon emissions, we need to achieve net-zero by 2050 to meet the Paris Agreement target and limit global warming to 2°C. Timber sequesters an average of 1.9 metric tons of carbon-dioxide equivalent emissions per cubic meter (Sathre & O’Connor, 2010). While a purely mass timber tall building may not be the most cost-efficient solution, a hybrid structure can maximize the overall use of wood by volume in the most cost-efficient manner. Floor systems in buildings contribute as much as 73% of the environmental impact of a high-rise building’s structure (Lankhorst et al., 2019), making them an excellent target for reducing embodied carbon. DIALOG’s patent- pending Hybrid Timber Floor System (HTFS) takes advantage of the benefits of cross-laminated timber (CLT) combined with pre-stressed concrete to achieve a 12-metre column-free span. The HTFS is proposed as part of our Hybrid Timber Tower, a 105-storey mixed-use prototype that is being evaluated and tested by DIALOG and EllisDon. The prototype structure consists of the hybrid timber floor, combined with a concrete core and an external steel frame. Fire safety is achieved in the floor panels as the exposed wood chars to form a protective layer, while the non-combustible concrete and steel band continues to support the panel. The exposed CLT panels also provide a biophilic appeal, which has shown to support cognitive function as well as physical and psychological well-being (Vidovich, 2020). DIALOG, EllisDon, FPInnovations and other partners have completed the first phase of small-scale testing on over 40 panels. We are scheduled for fire testing of the panels in Ottawa with NRCan this fall with full scale testing of the 12-meter panels starting in late 2022. Learning Objectives Describe how hybrid mass timber systems—such as the Hybrid Timber Floor System (HTFS)—reduce embodied carbon and support zero‑carbon goals in high-rise, mixed-use developments. Explain the structural, fire safety, and performance characteristics of hybrid CLT–concrete floor assemblies, including how charring, concrete bands, and steel elements contribute to long-span capability and code compliance. Evaluate the role of multidisciplinary research, prototyping, and large-scale testing in validating hybrid timber technologies for supertall applications, including their impacts on sustainability, biophilia, and cost efficiency.
