Six years after the launch of the concept, project partners Dialog and EllisDon could be just a year or so from hitting the market with their new Hybrid Timber Floor System. Using a prototype composite of post-tensioned concrete, cross-laminated timber, rebar and an engineered coating, the invention with its 40-foot panels would allow mass timber–based floor systems to be used in non-residential long-span construction such as office and institutional, sectors that until now have been limited to traditional building materials. Dialog, an architectural firm, and EllisDon hosted a project update event at the University of Toronto on Jan. 24 in collaboration with WoodWorks and the Mass Timber Institute. The event was billed as Hybrid Timber – Low Carbon and Long Spans. …To capture the attention of owners, designers and engineers, the partners created the floor plate for prototypical use in a 105-storey office building.
