Steve L. Lauer

Senior Associate


Steven Lauer has gained specialized experience through his involvement with the inspection, instrumentation, retrofit, and design of various steel and concrete bridge structures. To support these efforts, he has performed nondestructive testing in both the laboratory and on in-service bridges. Mr. Lauer is also well-versed in several structural analysis programs and has used his skills to perform reviews of structural adequacy and code-compliance for a variety of steel, wood, concrete, and tensile membrane structures.

Mr. Lauer’s previous work experience includes the design of both vehicular and pedestrian bridges, which has strengthened his ability to review in place structures. His work as a graduate teaching assistant focused on steel design, structural analysis, and structural dynamics. Mr. Lauer also performed field inspections and conducted research based on damage assessment of failed structures due to earthquake loadings.
