Gerwick has pioneered the development and application of large diameter tubular piling, and off-site prefabrication and overwater installation of large foundation substructure elements. Our solutions reduce the time for construction, while minimizing risks and improving safety. 

Additional services include seismic and soil-structure-interaction analyses, FE modeling, assessment of ice loads, debris impact loads, ship impact protection systems, waterway traffic studies, ship collision risk analyses, cofferdams, float-in construction, hydraulic modeling, coastal engineering, geotechnical engineering, and foundation solutions for areas with weak soils.
