About Timberlab INC.

From timberlab.com

Tanya Luthi is a structural engineer and the Director of Engineering at Timberlab, a full-service mass timber company with expertise from preconstruction to manufacturing, fabrication, and installation. Tanya’s undergraduate degree is in political science, but a change of heart after graduation sent her back to school for a master’s degree in civil engineering at The University of Texas at Austin. She began her career in New York City primarily designing large-scale institutional projects in steel and concrete. After moving to Vancouver, Canada in 2011, she discovered a love for mass timber design, which stayed with her after returning to the US in 2016. In 2023, after nearly 20 years as a design consultant, she joined Timberlab, whose turnkey approach to mass timber buildings allows her and her team to optimize their designs for fabrication and construction. In addition to her design experience, Tanya co-authored the US and Canadian Nail-Laminated Timber Design and Construction Guides, and she gives regular talks on timber design at architectural and engineering conferences across North America. She is a former member of the WoodWorks Board of Directors and an active member of the New York City structural code committee advocating for the wider adoption of mass timber.
