GRAEF offers a wide range of bridge services for highway, railroad, pedestrian, and utility bridges. Our services vary from structural consulting and maintenance inspections to complete project management.

Design and Rehabilitation
The GRAEF staff has the background to design single or multiple span bridges, with structural systems that best meet your site’s requirements. We have designed bridges over small streams for local townships and architectural or commercial clients, grade separation structures for state and federal agencies, and bridges over railroads and large rivers for municipalities.

Aesthetics
GRAEF embraces the challenge of inspecting and designing repairs or reinforcements for older bridges that sometimes require an artful blend of old and new structural systems. We do this while paying attention to aesthetics, budgets, and public concerns.

Inspections

GRAEF has inspected many bridges for state inspection programs in Wisconsin and  Illinois, more than 800 of which included load ratings. In addition, our PONTIS Bridge Management System inspectors are available to provide this specialized inspection.
