This live web event has ended. Thank you for attending.


Using a special application of timber concrete composite, the KF Aerospace Spiral Stair is comprised of doubly curved and warped CLT with a concrete topping throughout the full spiral. Addition of concrete provides the required mass to control vibrations in the 70ft long free span. Creating composite action between the concrete and the CLT significant increases the overall stiffness of the stair, removing the requirement for any support columns and maintaining a highly aesthetic structure that serves as a welcoming showcase for the aerospace museum, and a tribute to continually pushing the boundaries of what is possible with timber construction.

  • Lucas Epp, P.Eng., P.E.

    Lucas Epp is a structural engineer with more than 18 years of experience working in Canada, the UK, Asia, and New Zealand. His expertise with complex geometry and challenging structures has led him to be involved in projects where the intimate interaction of architecture and structure is critical to the success of the project. He is passionate about timber engineering and has built a team at StructureCraft of more than 50 timber engineers and designers hailing from around the world. Lucas currently leads both engineering and drafting departments at StructureCraft. His proficiency in Rhino + Grasshopper, programming, and computational design techniques facilitate and enable use of next-generation technology to create holistically efficient timber structures, from design through to manufacture and construction. Lucas speaks and writes widely across North America on mass timber design and construction, and has lectured at the Architectural Association in London, ETH Zurich, and the University of British Columbia. He is extensively involved in timber code development and was a member of the Structural Working Group for the ICC Tall Wood Code Committee, and also sits on various CSA O86 timber code committees. He is an author of the Nail Laminated Timber Design Guide, and is an author of the recently published U.S. Mass Timber Floor Vibration Design Guide.
