We address complex challenges resulting from continued growth, high-traffic volume, overworked transportation networks, and aging infrastructures. With significant experience in alternative project delivery methods, our superior local knowledge is backed by the deep resources and stability of a national company. We are committed to safety and the well-being of our communities, and it’s an integral part of how we approach every project.

Our Expertise


We are committed to delivering infrastructure solutions and services that improve highways. Over the past decade, we have consistently ranked in the top 25 highway designers by Engineering News-Record. We have also delivered more than $6 billion in critical transportation design-build projects for a variety of department of transportation clients.


From simple culverts to complex interchanges and long-span bridges, our respected industry experts use the full spectrum of modern construction techniques and materials, including steel trusses, curved beams, box beams, precast/prestressed concrete, timber, and fiber-reinforced polymer spans, with unique architectural treatments and other features.


Regardless of the project type, we understand the universal rules for work on, over, adjacent to, and under a railroad. We meet the need to maintain operations, ensure safety and security, and minimize disruption to the travelling public and the surrounding environment. We deliver inspection, engineering, and design services for freight, commuter rail, and mass transit agencies.

Ports and Intermodal

We offer expertise in a broad range of port-related planning and engineering services. We work with federal agencies and large port authorities to support the evaluation, rehabilitation, and modernization of piers and docks. Our varied experience allows us to develop recommendations for capital improvements and adaptation strategies to be made over time to improve terminal resilience.
