Transportation: Exposure & Performance

Transportation structures must perform under heavy loading, vibration, and long service-life expectations. Many assets are also exposed to chlorides, moisture, and freeze–thaw cycles that accelerate deterioration.

​

Owners and project teams need interventions that fit staging, access, and traffic constraints. The priority is to understand what is happening, confirm why, and select repairs that improve reliability and lifecycle value.

​

BAU supports practical solutions that can be built safely while maintaining service continuity.

Typical Assets and Common Issues

BAU is typically involved where deterioration affects safety, serviceability, or lifecycle cost. Common assets and issues include:

​

• Bridge decks, joints, bearings, and substructures.

• Concrete and steel elements exposed to chlorides and moisture.

• Protective systems such as waterproofing, coatings, and corrosion control.

• Rail-adjacent structures and supporting elements.

How BAU Supports Your Project

Work often starts with inspection and a testing program sized to the decision you need to make. BAU identifies deterioration mechanisms, quantifies extent, and translates findings into repair concepts, durability strategies, and staged scopes.

​

During construction, BAU supports issue resolution when field conditions differ from assumptions. We help teams evaluate deviations and manage their impact on long-term performance.

​

Where needed, BAU provides documentation and technical input that improves coordination between owners, designers, and contractors.
