In this presentation Don Hazelden looks at the current state of concrete high rise envelope design in the Vancouver area.  His presentation spotlights the top twenty areas of design and construction “faux pas” that give rise to water ingress problems.  He points out the issues and delivers practical approaches to head off the problems.  He focuses on the mating of concrete elements with the roofing, window wall, curtain wall and metal panel cladding systems that make up the majority of today’s high rise apartment building envelopes.  Practical guidance is presented for the design of the concrete outline which will allow enclosure elements to work successfully.
