David A. Schnerch

Associate Principal

 
Experience

Since joining WJE in 2005, Dr. David Schnerch has completed a wide range of failure investigations, structural evaluations, load tests, and repair designs of buildings, bridges, parking garages, and other structures. This work has included evaluation of reinforced, prestressed, and post-tensioned concrete as well as masonry, steel, and wood structures.

Before joining WJE, Dr. Schnerch studied the repair of concrete and steel structures using ultra-high modulus fiber reinforced polymer (FRP) materials. This work focused on the repair and strengthening of existing structures and has been published in the Journal of Bridge Engineering, Transportation Research Record: Journal of the Transportation Research Board, and other publications.
