Engineering vital connections for our communities.

As a multidisciplinary infrastructure practice, we provide innovative solutions to build, preserve, maintain and enhance the world’s bridges. Since our founding, we have planned, designed, inspected, repaired, rehabilitated and constructed well over 1,000 bridges.

We have delivered award-winning designs over road, rail and waterways — from iconic long-span river crossings to unique pedestrian bridges that establish meaningful community connections. We have inspected major structures, led rehabilitation improvement programs, and have delivered cost-effective solutions to help owners extend the life of their infrastructure.
