Experience
Steve Lauer has gained specialized experience through his involvement with the inspection, instrumentation, retrofit, load rating, and design of various steel, concrete, and timber 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, concrete, timber, and tensile membrane structures.
