As Seen at JLC LIVE! this one and half hour seminar covers the best practices I demand from my contractors when they are building plywood walking decks. I show you the various requirements for plywood substrate, sloping, blocking seams, calculating beam deflection and much more.

Deconstructing Berkeley-Designing Waterproof Balconies and Decks

Currently under construction, this seminar will shake the industry to it’s core. I break down each design & construction issue that the failed Berkeley balcony had that led to its failure, killing 6 students and seriously injuring 7 others who were visiting from Ireland. This seminar is for architects that shows you why simpler is better. Decisions have consequences and decisions must be thought out carefully against the clients wants and demands vs what you need to do to design waterproof decks properly.
