The Cedar Rapids office has been providing geotechnical and CMET services for the new U.S. Federal Courthouse since April 2009. The geotechnical scope of work consisted of performing a site bedrock study using a combination of soil borings advanced to bedrock and seismic refraction. Terracon also provided subsurface exploration and foundation recommendations for the two on-site tower cranes. The CMET services consisted of performing a site precondition survey of the neighboring properties and pavements prior to construction. During construction, Terracon provided full-time observation of driven pile installation, concrete placement for the foundations, slabs on grade, and elevated composite deck slabs, and unit masonry construction. Terracon also provided periodic observation and testing of structural fill placement, and spray-applied fireproofing. Construction of the project is expected to be completed in November 2011.
