GeoConcepts provided geotechnical engineering design and materials testing services for a transit-oriented mixed-use development anchored by the WMATA Spring Hill Metro Station, including retail, office and residential components, as well as nine public spaces. The development includes three buildings with 250,000 SF of retail, 40,000 SF of office, and 700 residential apartments.
