Vancouver-based Fast + Epp Structural Engineers has released a free online timber design tool that its in-house inventors say has the potential to save architects and developers countless hours in the early stages of project design.

Fast + Epp senior engineer Tobias Fast said in a recent interview the firm’s new Timber Bay Design Tool has already been tested out by thousands of architects, designers and builders in its first few weeks online.

The app gives users instantaneous feedback on volumes and configurations of timber use in proposed projects by providing specific member sizes, volume outputs and a 3D visualization of mass timber grids being contemplated.

Calculations based on user inputs are performed to size up the deck, purlins, girders and columns and displayed in 3D, and output tables display the results along with material takeoffs.
