For this $310M Collaborative Design-Build Stadium Development project at the former SDCCU Stadium site, Group Delta, an NV5 Company, provided design geotechnical recommendations, as-needed design phase consulting to the Design-Build Team, plan and specification review, and construction phase services including geotechnical testing and observation, import fill management, and settlement monitoring coordination. Geotechnically significant components included large mat and shallow foundation systems supported on over 2,000 stone column ground improvements used for foundation reinforcement and liquefaction mitigation, multiple 40-foot tall Mechanically Stabilized Earth and reinforced concrete basement walls, deep remedial grading to remove surficial compressible materials, settlement monitoring, and screening over 100,000 cubic yards of imported fill for MSE Wall backfill, structural fill, and general grading material.
