Foundation Engineering has completed geotechnical investigations and site‑specific seismic hazard studies for over 20 new and existing buildings on the Oregon State University (OSU) Corvallis campus. A selected list of recently completed projects is provided below.
Oregon State University completed a seismic upgrade to Strand Agriculture Hall, located on the west side of SW Waldo Place. The 4‑story, ±100‑year old structure consists of a north, south and middle section built with unreinforced brick and mortar. The retrofit structurally upgraded the building to resist collapse. The upgrade also included the construction of a new canopy structure at the west building entrance. The canopy is supported by spread footings.
Foundation Engineering provided a site-specific seismic hazard assessment for the retrofit. Our scope of work also included field exploration, laboratory testing, engineering analysis, and development of recommendations for foundation design and construction.
This 5‑story, ±90,000 GSF concrete and steel hybrid structure includes a basement and an 8,000 SF exterior glass-covered canopy. This project achieved LEED Gold certification utilizing a number of sustainable designs: energy efficient and day lighting, passive/natural ventilation, and highly efficient mechanical, plumbing, and electrical systems.
Our work included a site-specific seismic hazard study, field exploration and lab testing, basement wall and a sub‑slab drainage system design, and recommendations for site preparation, foundation design, and construction. Analyses suggested the silty sand was susceptible to liquefaction. Therefore, ground improvement utilizing Geopiers was selected to mitigate the liquefaction hazard and increase the bearing resistance of the foundation soils.
The Centro Cultural Cèsar Chàvez is a single‑story, 3,565 SF building that serves the university’s Latino students and 17 student organizations.
We completed the geotechnical work for the project that included a review of previous subsurface data from the area, engineering analysis and design for spread footings, and development of wet weather construction recommendations for site preparation, foundation design and construction. Foundation Engineering provided construction observations services during building pad and foundation preparation.
This 5-story structure houses approximately 350 international and domestic students, new classrooms, offices for faculty and support services, a 110-seat classroom auditorium, and retail space that houses a coffee shop and market.
Foundation Engineering provided a site specific seismic hazard study, rigid and flexible pavement design and development of recommendations for site preparation, foundation design and construction. This project included the redesign and construction of SW A Avenue and SW 16th Street that border the north and east sides of the site.
This four story, 100,000 square-foot structure includes ten classrooms, a 250-seat auditorium, more than 70 offices, a café, and event space. The site was challenging due to potentially liquefiable soils that were identified across the ±25,500 SF building footprint.
We completed a site specific seismic hazard study, field exploration, field and lab testing, engineering analysis, and recommendations for site preparation, foundation design, and construction. Analyses suggested the silty sand was susceptible to liquefaction and liquefaction-induced settlements. Therefore, ground improvement consisting of vibro-replacement stone columns was selected to mitigate the hazard and increase the bearing resistance of the foundation soils.
This 4-story state of the art facility has a partial, ±12,100 SFbasement extending ±17 feet below-grade. Foundation Engineering conducted a geotechnical investigation and seismic hazard study for the new building. The basement presented geotechnical challenges including construction dewatering and shoring, and required the evaluation of static and seismic lateral loads on the basement walls. The investigation included evaluation of seismic hazards including liquefaction, ground amplification, and settlement.
This ±34,000 SF Student Success Center marked 80+ successful projects completed by Foundation Engineering for OSU over the previous 30 years. The Center includes classrooms, a computer lab, study lounge and commons area as well as academic counseling and advising offices, meeting rooms, and tutorial spaces. The second and third floors are home to two transition programs for students, September Scholars and the BEST Program, a similar program for student-athletes.
Our services included exploratory drilling, laboratory testing and preparation of the geotechnical investigation and seismic hazard study report. We were also on-site during site preparation and foundation construction to verify the subgrade conditions and foundation design criteria.
This all-weather park hosts three lit turf fields, a 1/3-mile track, a 10-court tennis complex, a basketball court, and a pavilion. The fields support a variety of purposes including drop-in recreation, Intramural Sports, Sports Clubs, and Physical Activity Course (PAC) classes.
Foundation Engineering provided geotechnical design and construction-phase services. On-site water storage was ultimately selected based on the low permeability native soils. The geotechnical work also included developing mitigation options for expansive soils, foundation design for the new pavilion, and wet weather construction recommendations.
This facility includes an indoor track, 22 Olympic platforms, 45 pieces of cardiovascular equipment and free weights, and the Beaver wrestling area and player lounge.
Foundation Engineering provided field exploration, foundation analysis and design. A site-specific seismic hazard study was completed to address geotechnical and geologic hazards such as seismic sources, liquefaction, and ground amplification.
Over the years, OSU has made numerous improvements to its football stadium, currently named Reser Stadium. Since 1990, Foundation Engineering has provided geotechnical services for stadium improvements and expansions. Between 2003 to 2007, we provided geotechnical services for the east side expansion that increased the seating capacity from 35,362 to 43,300 and the south end zone that increased seating capacity from 43,300 to its current capacity of 45,674.
One of OSU’s most historic structures built in 1902 was gutted and rehabilitated to current building code and seismic standards. Foundation Engineering’s work included a foundation investigation and site-specific seismic hazard study. Analyses included evaluation of the liquefaction hazard and ground response. Recommendations were provided to retrofit existing foundations to resist seismic loads using a combination of tension anchors and increased footing sizes.
Foundation Engineering provided field investigation and design of rigid and flexible pavements for numerous projects on and around campus. Projects included complete reconstruction of Campus/City of Corvallis streets using flexible or rigid pavements and grind and inlay. Several of these projects utilized porous pavements to manage runoff.
Foundation Engineering also provided foundation design recommendations for a bridge on campus.
This 4-story, ±34,500 SF state‑of‑the‑art facility includes two regulation courts on the first and third floors along with locker rooms, satellite training and medical areas, and service and mechanical spaces.
We provided geotechnical services for the project using existing information developed for the Center and verifying foundation subgrade conditions during construction. The south wall of the new facility is separated from the north wall of the Center by a 4-inch wide seismic gap. Therefore, design challenges included widening the existing (north wall) footing of the Center to accommodate the additional wall load of the Basketball Practice Facility.
School of Chemical, Biological, & Environmental Engineering - Johnson Hall
Johnson Hall will be the new home for the School of Chemical, Biological, and Environmental Engineering (CBEE) in the College of Engineering. The new, 3-story, ±60,000 SF building will also include pedestrian improvements and new concrete and asphalt parking. Foundation Engineering completed a geotechnical investigation and site specific seismic hazard , exploratory drilling and seismic cone penetrometer testing (SCPT), laboratory testing, engineering analyses, and development of recommendations for site preparation and foundation design and construction.
