Mass Timber

Timber is a renewable, fire resistant, structurally sound, and viable alternative to steel, concrete, or masonry. As the need for sustainable building continues to grow across North America, PCL is supporting the use of mass timber to help reduce the carbon footprint of the buildings we build.


Accelerated project delivery - Mass timber offers many construction efficiencies, including opportunities to modularize, up to 20 percent schedule acceleration, 90 percent reduction in construction traffic, 75 percent fewer workers onsite, and minimal tolerance issues. 

Carbon and waste reduction – Wood is a renewable and sustainable resource. It assists with carbon sequestration and requires significantly less embodied energy than concrete and steel to manufacture and install. Because of the prefabrication and manufacturing options available, using mass timber can reduce impacts to water quality in comparison to other systems. 

​Preconstruction services and value engineering​Mass timber provides many design efficiencies due to its high strength-to-weight ratio which allows for smaller foundations and lower forces for seismic resistance. Wood structures can have excellent fire ratings with char layer protection and an up to three-hour fire rating. It also allows f​​or biophilic design with enhanced design aesthetics and exposed structural wood throughout. 


This six-floor structure was one of the tallest contemporary wood buildings in North America at the time of construction. The primary structure is 100 percent wood and used construction methods that virtually eliminated the use of concrete above grade.
Colorado State University Pavilion at Laurel Village​
The Pavilion is a cross-laminated timber stru​​​cture with a stone, glazing, and metal panel exterior. Key project ​elements include passive heating and cooling systems within the katabatic tower and trombe walls, a sloped green roof rising from the performance green, and a living green wall.
