Webinar – Structural Grids, Fire Resistance and MEP: Holistic Coordination in Mass Timber Design

October 13, 2021 – 12:00 pm - 1:00 pm




As of October, 2021 we will be moving our webinar platform to Zoom.

Join at 10 am Pacific, 11 am Mountain, 12 pm Central, 1 pm Eastern

Designing a mass timber building that is efficient—both in its use of timber fiber and application of code provisions—requires a high level of preconstruction coordination across all facets of design. Delivered by experienced structural and mechanical engineers, this presentation will address some of the critical decisions that should be made as early as possible in mass timber projects. These decisions can have a big impact on cost and either increase or limit opportunities later in design (the ripple down effect). Topics will include the unique role of the supply chain in the efficiency of a mass timber project, construction types, fire ratings, column grids and beam/panel spans, and MEP integration.
