Michael J. Drerup, P.E.

Mr. Drerup has over 12 years of structural engineering and building technology experience with an emphasis on the long-term performance and durability of contemporary and historic structures and building envelope systems.

Mr. Drerup has planned and executed numerous building performance studies that have included both in-situ and laboratory test programs. He has directed and participated in studies to evaluate the long-term performance and durability of concrete, wood, steel and masonry structural systems. Mr. Drerup also specializes in the diagnosis and remediation of water intrusion issues and the durability of cladding materials exposed to severe weathering environments. He has investigated performance issues with a variety of façade types including metal and glass curtain wall systems and exterior insulation and finish systems (EIFS). He has also planned and executed load tests and non-destructive structural surveys of existing buildings.

Mr. Drerup has investigated numerous damage claims resulting from a variety of natural and man-made causes, including weather events, explosions, fire, impact events, construction activities, and defective design or construction.
