Over the past decade, the resurgence of engineered wood products, such as cross-laminated timber for buildings, has inspired a change in the way we build. Driven by an effort of the construction sector to become more sustainable and have lower carbon impacts, cross-laminated timber presented an opportunity to try to build better. Mass timber is not just a building material but rather a design-to-build concept that includes the use of large and massive elements and building components from engineered wood, such as cross-laminated timber (CLT). In fact, most, if not all, mass timber buildings are often a combination of wood, steel, and concrete. This chapter will bring forward three distinct learning objectives revolving around: identifying and defining mass timber construction recognizing the current state of the mass timber construction globally defining the disruptive characteristics and best practices for using mass timber products in construction projects.
