The Gallup Organization (Gallup) entered into a contract with the City of Omaha to redevelop a portion of Omaha's downtown industrial area into a new Gallup training and technology campus along Omaha's riverfront corridor. Terracon provided subsurface exploration, geotechnical analyses, foundation and site preparation recommendations for the office complex, as well as, the review and monitoring of environmental services conducted by the City of Omaha. The Phase I project site fronts the Missouri River on the site of a previous scrap metals recycling facility, a fertilizer and asphalt storage/dock facility, and the previous alignment of Abbott Drive. Environmental concerns related to this project included subsurface contaminants from metals, ammonia fertilizer, and petroleum attributed to past site use and hazardous waste activities. Terracon's services to Gallup included: subsurface assessment, confirmation sampling, risk-based evaluation of potential vapor intrusion into future structures, review of documents (assessment results, remedial action plans, restrictive covenants), and collaboration with state regulatory personnel. Terracon also provided construction-phase testing and Special Inspection services for the office complex.
