Andrew E.N. Osborn

Senior Principal


Since joining WJE in 1978, Andrew Osborn has participated in more than one 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, he has developed expertise in investigations performed for, or on behalf of, insurance companies and/or their subrogation counsel. Prior to WJE, Mr. Osborn was a Project Engineer at DeLeuw Cather and Company (now Parsons Infrastructure), where he designed over twenty-five post-tensioned box girder bridges for the Kuwait Motorway System.
