Parking Structure Requires Special Handling of Soil

More than 350 truckloads of concrete pour was required for one of several major pours in the construction of a 1,125-car, $6-million parking structure that will connect Mission Viejo’s Mission Hospital Regional Medical Center with its new 16.5-acre, low terrace addition.

According to soil analysts, the parking structure is positioned atop a prehistoric alluvial fill and in order to support the construction, 147 footings were poured, most of the extended depth to reach below the soft alluvial soil level.

The 370,000-square-foot structure is the second recent building activity to occur on the newly acquired property. A $4-million project began in July to provide tenant improvements for a new five-story medical office building that was part of the property purchase.
