Transportation

SDA provides innovative highway and bridge design, as well as traffic engineering solutions to fit our clients' ever-changing transportation needs. Our professional experience spans a wide range of facilities for hundreds of miles of rural and urban highways, bridges, and railroad structures. Our expertise and innovative ideas enable us to provide economical designs for function, safety, and constructability while enhancing the quality of life for those it serves.

SDA has developed design and traffic control plans for hundreds of miles of rural and urban roadway, bridges, and railroads that carry a variety of traffic volumes. The firm's experience and innovation in road, bridge, and traffic engineering enables our design to be within budget and on schedule for state, counties, and municipal communities.

Our team of professionals possess an in-depth knowledge of the design, engineering, and construction standards associated with the Michigan Department of Transportation (MDOT), as well as requirements for the National Bridge Inventory System, National Highway System, and other federal programs. SDA's positive working relationship with Federal, State, and County agencies offers time and cost efficiencies to clients requiring coordination or compliance with these agencies.

In addition, SDA has made a commitment to quality control by engaging an internal Quality Management System (QMS) representative to oversee the progress of each transportation project. Our QMS representative periodically reviews the project's scope, design schedule, and constructability. These reviews promote quality assurance both internally and externally resulting in highly efficient projects for our clients.
