Bridge Engineering and Inspection

Bridge Engineering and Inspection

As time takes its toll on our country’s aging bridges, the scrutiny that is necessary to provide for their longevity becomes all the more important. Demand for well-educated, motivated bridge engineering professionals who specialize in both inspection and custom bridge design has never been higher. Today’s bridge engineer must simultaneously employ the most sophisticated design techniques while simplifying the most complicated bridge configurations and construction sequences.

CEC can provide design for anything from interchange flyovers to rural stream crossings. CEC designs steel, prestressed concrete, and post-tensioned concrete bridges, retaining walls, sound walls, and drainage culverts, to provide effective transportation solutions. Other services include bridge rehabilitation assessment and plan production and emergency repair consultation.

CEC has contracted with several counties, municipalities and the Oklahoma Department of Transportation to provide bridge inspection services for the past 20 years. The type of structures inspected range from small county road structures to the Pensacola Dam roadway.

“It’s a credit to the engineering profession that bridges tend go unnoticed by most of the general public. Whenever a bridge is closed or lost to use, we are all reminded of the vital role bridges play in connecting communities and enhancing our daily lives. The role we take on to maintain that expectation is a responsibility we both respect and cherish.”
