Time and again our clients tell us they chose Schnabel as a design partner for their highway and bridge projects for the same reasons: We bring unmatched specialization and expertise to help them manage underground risks and identify cost-effective solutions to complex geotechnical problems. And they recognize we understand DOT requirements and processes for both traditional and alternative delivery projects.

Schnabel has over 100 engineers and scientists with experience on thousands of highway and bridge projects, including new alignments, roadway widening, bridge rehabilitation, interchange modifications, and interstate corridor projects in both rural and urban settings. We also have specialized experience with heavily loaded bridge foundations for water crossings, embankments over soft ground, retaining wall design, accelerated bridge construction, seismic analysis, and geohazards mitigation including karst and slope stabilization.
