Bridge Inspection
Since 1978, WSP has inspected more than 34,000 bridges; everything from world class suspension bridges to masonry arch culverts in pastoral settings.

Bridge Rehabilitation
Our bridge engineering experts possess knowledge in the assessment of existing bridges and provide investigation reports of structures, as well as developing innovative solutions. In addition to our bridge inspecition services, we provide bridge assessment and remediation, strengthening and reconstruction as well as deconstruction plans. We have extensive experience with a wide variety of structures, from historic cast-iron beams and masonry arches to modern steel-girder and concrete superstructures.

Bridge Diagnostics
Our bridge engineers understand the role that condition assessment and prioritization of repair needs play in managing bridge assets. Our bridge diagnostic technology - utilizing field instrumentation, load testing and finite element analysis, can determine actual capacity and help identify potential weak spots. We combine this technology with our assessment technology, which can evaluate the level of corrosion through the structure - by utilizing non-destructive techniques to determine the remaining service life of the bridge in a proactive versus reactive manner.
