With four levels and a maximum total height of 47 feet, Hollister Retail and Parking Structure offers 188 parking spaces and 10,700 square feet of retail space on the ground floor level. The concrete structure is supported on a prestressed driven pile and grade beam foundation. The columns and walls are constructed of conventionally reinforced concrete with prestressed concrete suspended slabs and beams. For this major downtown development project, Earth Systems performed the initial geotechnical investigation and the environmental preliminary site assessment. During construction, the Earth Systems team provided observation and testing of engineering fills and pile driving inspection.
