ABNA provides structural design and project management on many types of facilities: bridges, tunnels, retaining walls, specialty structures, prestressed concrete for industrial buildings and parking structures, and platforms for transit structures and specialty structures. Our structural engineers have facilitated seismic designs for a variety of bridge projects along major interstates in addition to bridge inspections. We have provided in depth inspections of rebar, steel bolt, girder and shear stud connectors, coordinated with various authorities to prepare design and construction reports, and provided value engineering and structural design reviews to determine structural integrity of bridges.
