What We DoTransportation





For projects that involve roadways, intersections, interchanges, facilities, pathways, or related studies, clients look to the expertise we’ve earned over more than 75 years serving Northern California’s transportation needs. Many of the region’s notable and award-winning projects originated from our engineers’ designs.

Start-to-finish engineering services include innovative, yet cost-sensible solutions that help clients design, manage, create, or upgrade:

Streets and highways
Pedestrian and bike pathways
Facilities
Interchanges
Bridges
Planning studies
Transit facilities


In addition to engineering and related surveying services, we help clients minimize confusion by working with community members to arrive at and communicate agreed-upon solutions.

We offer conceptual design to final engineering drawings of bridges, roadways, and structures, and provide all engineering-related services for transportation projects, including:

Caltrans project reports
Construction staging and traffic routing
Cost studies
Drainage analysis and reports
Public outreach
Right of way engineering
