BRIDGES AND HIGHWAYS

 

Construction of concrete and steel bridges, tunnels, deep foundations, and retaining walls is often technically challenging. This type of work is one of KBA’s specialties. Through attention to detail and persistent follow-through, KBA helps achieve the desired durability and quality of the structures while minimizing the impacts generated during the intensity of construction.
