PeaceHealth RiverBend Campus | Springfield, Oregon

PeaceHealth RiverBend Campus | Springfield, Oregon

DESCRIPTION:  PeaceHealth Hospital constructed a new medical campus in Springfield including a 1,000,000 SF 5-story hospital with a 9-story tower, a 150,000 SF 5‑story Oregon Heart and Vascular Institute (OHVI) building, a 125,000 SF 5-story RiverBend Medical Pavillion (RMP) building, a 30,000 SF central utility plant, and 4-story and 7‑story parking structures with more than 1,000 parking spaces.  The project also included paved roadways and parking lots and extensive underground utilities.    

SERVICE:  Foundation Engineering provided geotechnical consultation for the project beginning with the preliminary planning and extending through the end of construction.

The site is underlain by silt over alluvial sand at depths ranging from 4 to 15 feet.  The compressibility of the silt was a key geotechnical consideration.  Overexcavation and replacement of the silt was used for the OHVI and central utility plant utilizing gravel excavated from the hospital basement and imported granular fill materials.  Geopiers were used to support the parking structures and RMP where the silt was left in place.  The main hospital building has a basement, which extends to the gravel stratum.
