Terracon conducted geotechnical investigations to evaluate general subsurface conditions at the proposed site with respect to the design and construction of the new Raleigh Civic and Convention Center and associated underground parking deck. The scope of services included test borings, laboratory testing and engineering analysis. Terracon performed Phase I environmental site assessments (ESAs) at 19 separate property parcels on approximately two and a half city blocks (approximately 10 acres) that will comprise the future site of the convention center. The property parcels consisted of developed and undeveloped properties, including the site of a former manufactured coal gas plant, vehicle maintenance facilities, service stations, dry cleaning facilities and the site of a former garbage incinerator. The Phase I ESAs also included a comprehensive survey and sampling of building materials for the presence of asbestos and lead-based paint. Based on the Phase I ESA, Terracon identified numerous onsite and offsite recognized environmental conditions from current and historical activities that have warranted Phase II intrusive activities. The Phase II limited site investigation is ongoing at the site, and consists of installing groundwater monitoring wells to assess the impact to groundwater and subsurface soils at the site from both onsite and offsite activities. Terracon currently is providing special inspections and construction materials testing during construction of the convention center. The inspections and testing program includes soil sub-grades, soil density testing, secant wall inspection and testing, soldier pile wall inspection and testing, concrete inspection and testing, reinforcing steel inspection, and structural steel inspection and testing, Terracon also is providing final documentation review and project design/specification review for the project.
