Construction Time
With positive net growth in North American forests, timber is a readily available renewable material. Requiring less embodied energy, heavy timber has a lighter carbon footprint compared to other traditional building materials. Rather than producing carbon, as is the case for concrete and steel, timber sequesters carbon. Mass Timber?
Combining aesthetic beauty with enhanced air quality, acoustics, thermal comfort, and energy efficiency, heavy timber is natural choice for the healthier work environment. Additionally, the biophilic quality of being connected to nature creates a happier and more comfortable space for occupants to enjoy.

Why
Occupant Experience
With advancements in technology, heavy timber construction can be shipped to the site in prefabricated sections and assembled quickly and safely. With reduced on-site labor and an accelerated construction schedule, heavy timber buildings are becoming more affordable and can result in direct cost savings.

As one of the oldest and widely used mass timber products, glulam’s application is broad and includes virtually all building types. It is particularly well suited to long-spanning structures and custom curvilinear shapes, and combines well with hybrid assemblies and building systems.
Glulam is composed of individual wood laminations, selected and positioned based on their performance characteristics, and then bonded together with durable, moisture resistant adhesives. The grain of all laminations runs parallel with the length of the members, which can be customized to create elements that are straight, curved, arched, and tapered.

Cross-Laminated Timber
Sourced from: Mass Timber Design Manual – Volume 2 developed by WoodWorks and Think Wood.
Cross-laminated timber (CLT) is a wood panel system consists of layered lumber boards stacked and glued crosswise at 90-degree angles, delivering excellent structural rigidity in both directions. Alternating grains improve CLT panels’ dimensional stability. Finger joints and structural adhesive connect the boards. Common applications include floors, walls, and roofs. Other applications include cantilevered floors and balconies, loadbearing elevator shafts, and stairs. The panels’ ability to resist high racking and compressive forces makes them especially cost-effective for multistory and long-span diaphragm applications. In structural systems, CLT panels serve as load-bearing elements and are well suited to taller timber construction. CLT can be left exposed in building interiors—up to 8 or 9 stories in Type IV-C buildings under the 2021 IBC (depending on occupancy), offering additional aesthetic attributes..

Historically, industrial buildings often used NLT construction to span between solid timber posts and beams and form sturdy solid floors. Many of these buildings are sought after for their historic appeal and continue to serve today as refurbished office and residential spaces. NLT’s revival is due in large part to domestic availability. The mass timber product does not require a dedicated manufacturing, and can be fabricated with readily available dimensional lumber.
Dowel-Laminated
Timber Why Mass Timber? Pickard Chilton15
Dowel-laminated timber (DLT) is a mass timber product commonly used in Europe and gaining popularity in North America. Panels are made from softwood lumber boards stacked on end and friction-fit together with dowels, typically made from hardwood lumber. Similar to NLT, DLT panels can be used for walls, floors and roofs, stairs and elevator shafts, or bent and assembled to create curved structures. DLT’s all-timber design, with no metal connectors, means it can be easily processed and cut using CNC machinery. Alternating patterns of lumber can be used to create various aesthetic appearances. DLT panels can also accommodate mechanical services and sound absorbing insulation, tucked away as part of its cut and design.
A century-old building construction material, nail-laminated timber (NLT) is made from dimension lumber stacked on edge and fastened together with nails or sometimes screws to form a solid structural element. Applications for NLT include floors, decks, roofs, and walls, as well as elevator and stair shafts.

At the core of each office building, a four-story atrium creates a communal area within the workspace and visual connections to adjacent floors. The palette of warm wood and local stone across ATCO Park responds to the adjacent Rocky Mountains and provides an inviting and welcome contrast to the winter climate. Timber is an essential component of the natural identity of Alberta. In addition to the sustainable carbon sequestration benefits, equivalent to the removal of 134 cars per year from the roads, each building’s timber heart roots it culturally in its environment.

Pairs of sensually curved laminated timber structures branch from the center of the great hall, parting to allow a continuous skylight to slip through the ridge of the leaf-shaped cantilevered roof with cross-laminated timber decking.
