DESCRIPTION: Construction is currently underway for the expansion of the Pastega Regional Cancer Center at the Good Samaritan Regional Medical Center in Corvallis, Oregon. The expanded facility will allow collaboration with Stanford Cancer Center to enhance cancer care, education and clinical research in the region. The new addition is a 24,000 SF, 2‑story steel-framed building. Tall retaining walls were required for the new building and modular block walls were built at the perimeter of the site to develop the sloping terrain.
SERVICE: Foundation Engineering, Inc. provided geotechnical services throughout design and construction of the project. Design elements included spread footings, slabs, pavements and retaining walls. Due to the project’s proximity to the existing cancer center and utility lies, oversteepened cut slopes were required. Foundation Engineering worked with OSHA, Devco Engineering and the contractor to develop a safety plan to allow foundation and retaining wall construction adjacent to ±20-foot tall cuts. Foundation Engineering provided daily monitoring of the cut slopes and recommendations for mitigating sloughing, retaining wall construction and backfilling.
