A Lincoln, Neb.-based construction company is suing Woodbury County, Iowa, and companies involved in the design and construction of the $70-million Woodbury Law Enforcement Center in Sioux City, Iowa, claiming it is owed $5.7 million for work on the project that was delayed by 17 months due to problems that the contractor says were not its fault and that it has suffered reputational harm related to county-initiated publicity.
