Construction Systems

Mass Timber Construction Systems

There is an ever-evolving number of options and systems when it comes to mass timber. Using various combinations and sizes, mass timber products can serve as beams, columns, floors, roofs, and walls considering the directional strength of each wood products. In contrast to conventional concrete and steel systems that tend to follow standard templates, mass timber systems offer the potential for greater flexibility, albeit not without some challenges.

Types of mass timber framing systems include:


Post-and-beam mass timber systems are a popular choice, and resemble the common approach used in historic heavy timber buildings of the past. It is a skeletal framework of decking, beams and posts supported on a foundation. The upright wood members are referred to as posts and the horizontal wood members referred to as beams. The post and beams are connected using mechanical steel fasteners. This system of construction requires no load-bearing walls. Glulam frequently serves as posts and beams. Decking systems can be made of panelised mass timber products such as NLT, CLT or others. The post-and-beam system works well for open plan designs such as offices and commercial buildings.

Mass timber floor and wall systems

In contrast to post-and-beam, designers can take advantage of mass timber panel’s two-way spanning capability. This can include mass timber panels constructed to form a honeycomb structure well-suited to handle both vertical and lateral loads. In these systems, mass timber panels—similar to reinforced concrete and steel—form both floor and wall, with the walls bearing the load of the structure. In some instances, mass timber may form the core of a building, in place of concrete.

Hybrid mass timber systems

Hybrid mass timber systems is a broad category that refers to any combination of wood, steel, concrete and other possible materials and building systems. Capitalising on the performance and strengths of each building material, hybrid systems offer lots of flexibility. This can include a nearly all-wood solution that combines light-frame wood construction with mass timber panels, where only the foundation is concrete, and the connecters are metal.

One of the greatest attributes that people and organisations share within the global mass timber construction sector is unity. Unity is what binds us, helps us to be better, to achieve more together and drive a different future.

Above all else, the mass timber construction sector is special and unique for its diversification for technology, process and methods of working.
