OCTOBER MEETING

PROTECTED MEMBRANE ASSEMBLY

A SOLUTION TO AN UNUSUAL ROOFING CHALLENGE

Presented by:  John P. Grossmann and Lyudmila Kogan

For our October meeting John P. Grossmann and Lyudmila Kogan will present a roofing project with several unusual challenges.  Challenges included developing a system that would have a useful service life of 30 years, and that could accommodate heavy foot traffic and continual maintenance activities related to existing mechanical and electrical equipment located on the roofs.

The presentation will focus on the process that was used in selecting a new roofing system, and how the performance characteristics of the selected roofing system will meet the client's long term performance objectives.  An overview of the selected roofing system will be presented as well examples of design solutions to atypical roofing conditions.  In addition a review of the quality control plan that was implemented during construction will be presented.  The presentation will conclude with a short discussion of how a similar roofing system might be adapted to a green roof.

Mr. Grossmann is the principal architect of the Grossmann Design Group and has been providing consulting services related to roofing and waterproofing for more than 20 years.  Services have included the analysis of roofing and waterproofing failures, the design of new roofing and waterproofing systems, and the development of guideline design details and specifications.  In addition he has developed several quality control programs related to the application of a variety of roofing types. Ms. Kogan started her career in Architecture in 1989 in Ukraine.  She has a degree in architecture from UC Berkeley.  Since 1999 she has been working for the Grossmann Design Group and specializes in the design of roofing, waterproofing, and exterior building envelope assemblies.  Ms. Kogan has extensive expertise in the detailing of roofing, waterproofing, and exterior building envelope assemblies.
