Experience
Since joining WJE in 1978, Andrew Osborn has participated in more than three thousand projects. He has conducted a wide range of investigations, repair designs, and load tests of buildings, bridges, water retaining structures, parking garages, tunnels, stadiums, and a lighthouse. These structures have been made of reinforced and prestressed concrete, masonry, steel, and wood. Since 1993, Mr. Osborn has developed expertise conducting investigations for or on behalf of insurance companies. He is also often designated as an expert in litigation matters. Prior to WJE, Mr. Osborn was a project engineer at DeLeuw Cather and Company (now Parsons Infrastructure), where he designed more than twenty-five post-tensioned box girder bridges for the Kuwait Motorway System.
