Bridges & Structures

If the most important element for you is speed of construction in the field, we can figure out how to replace your bridges very quickly, perhaps in as little as a weekend.

Meeting unique client needs often requires creative project delivery methods. Our bridge teams have partnered with clients to complete more than 50 design-build projects. We’ve served as program managers, managing both costs and risks in a results-oriented environment, used construction management/general contractor delivery methods, developed public-private partnerships and more — all in an effort to find the best approach to ensure success. 

We conduct studies that measure the structural response of a bridge under a variety of load conditions to determine its structural integrity. This provides data to make informed decisions about asset management.

We're at the forefront of BIM for Bridges and Structures, harnessing information at its origin to drive decisions, create better visualizations and improve communication between designers and contractors.

Our experienced engineer/inspectors maintain certifications and qualifications to inspect and evaluate all types of bridges and tunnels as required by the Federal Highway Administration. Our staff is comprised of National Bridge Inspection Standards (NBIS)-certified Team Leaders, National Certified Tunnel Inspectors (NCTI) Team Leaders in accordance with the National Tunnel Inspection Standards (NTIS), Fracture Critical Member (FCM)-certified Team Leaders, Society of Professional Rope Access Technicians (SPRAT)-certified inspectors (Levels I, II and III), and American Society for Nondestructive Testing (ASNT)-certified NDT Technicians (Levels 1 and 3). We continue to manage numerous bridge and tunnel inspection contracts for clients across the country, helping to maintain safe infrastructure for the traveling public.

Our clients face significant challenges in addressing the needs of their aging infrastructure, including how to cost effectively preserve and maintain their bridges to support overall highway mobility. From repairing to retrofitting, we develop innovative designs and approaches for long-term preservation, and we assist our clients in making informed decisions in establishing infrastructure resiliency.

Combining both art and science to bring form together with function, our bridge architects partner with our designers and our clients to develop and deliver solutions that achieve the community's vision. 

Using advanced 3D modeling, our engineers and architects can quickly develop multiple design concepts that meet specified needs and adapt designs quickly when modifications are needed. 

In regions where earthquakes are a concern, owners can modify existing structures to make them more resistant to seismic activity, ground motion or soil failure that can accompany earthquakes. We've led seismic retrofits of simple-span to long-span bridges, including some of the most recognizable in the U.S.

Different modes of transit have different bridge needs. We've designed client-driven solutions for pedestrians, streetcars, light rail, buses and more.
