Another long wet winter is taking its toll on the local slopes. On March 15, 2017, a 150-foot long section of slope above Kalama River Road failed, covering the road with trees and mud. The only available detour was over an hour long and involved several miles of private logging roads. Foundation Engineering helped Cowlitz County and their contractor assess the remaining slopes and develop an approach to safely remove the debris and reopen the road. Removal of the debris was complicated by stumps that were too large to fit in a dump truck, but the road was cleared and ready to reopen by March 31.
Oregon State University has begun the expansion of its College of Forestry facilities on the Corvallis campus. Two new buildings will replace Peavy Hall to create the Forest Science Complex. The Complex will include a new, 4‑story, 90,000 SF classroom and office building (Peavy Building) constructed with engineered wood products, and the new 18,000 SF A.A. “Red” Emmerson Advanced Wood Products Lab for testing and developing new engineered wood products. The A.A. “Red” Emmerson Lab will be home to the National Center for Advanced Wood Products Manufacturing and Design, a collaboration of architecture, wood science, and engineering programs driven to innovate sustainable building components in Oregon.
In keeping with OSU’s goals for sustainability, construction of the new Forest Science Center was developed with recommendations to support Resource-Sensitive Engineering. The demolition of Peavy Hall generated tons of debris and left a large, ±12‑foot deep hole in the ground that would require filling with structural fill to support a portion of the new Peavy Building. Foundation Engineering, in consultation with the design team and contractor, developed a plan to leave portions of the existing basement slab and walls in‑place, and process and re-use thousands of tons of concrete as on-site fill. Our firm developed gradation recommendations for processing and a performance specification for placement and compaction, and we are currently providing construction support and observations services for the project. The processing and re-use kept approximately 2,500 tons (±1,400 yd3) of concrete out of local landfills.
The Port of Newport is replacing several corroding, 14-inch diameter steel piles with 16-inch diameter, galvanized steel piles on Dock 5 and Dock 7. The project will increase the integrity of the floating docks, prevent the risk of damage to docking vessels, and remove three piles deemed hazardous to navigation.
Foundation Engineering was retained by the Port to provide geotechnical consultation and construction observation services.
Senior Engineer Tim Pfeiffer, P.E., G.E. is providing debris flow safety training to Oregon and Washington counties. Tim is Foundation Engineering's landslide and rockslide expert and provides emergency responses services to landslide-prone cities and counties. Tim's training presentation was developed at the request of County officials preparing response crews for the upcoming winter rains.
Foundation Engineering is excited to provide geotechnical engineering for the new Corvallis Museum! The Benton County Historical Society (BCHS) plans to build this new two-story, ±19,000 square-foot museum at the corner of SW 2nd Street and SW Adams Avenue in Corvallis, Oregon with projected completion in mid‑2018.
Our firm was proud to host Susan Conrad, Ph.D. for her seminar on Effective Writing for Civil Engineers.
In her seminars, Dr. Conrad presents real-life examples of engineering proposals, memos, and other writing in order to demonstrate the best way to convey exactly what the writer intends. She points out common mistakes that confuse readers and may even imply guarantees or liability unintentionally. Her seminar is informative and engaging, and we highly recommend her to other engineers.
This week, the men and women who have dedicated their lives to maintaining and improving our nation's quality of life are being celebrated for their contribution. Their hard work makes our daily lives possible. Unfortunately, their effort often goes unnoticed, and many of the functions they provide are relegated to background noise. We take for granted that our waste disappears from our homes, that we can drive to the grocery store, or that our lights will turn on. When we do notice public works, it's after disasters or when infrastructure or services fail.
This week, be mindful of the public works projects and services that make our communities possible, and remember that they can only work with the funding we provide them. Investing in public works is investing in our quality of life.
Foundation Engineering has completed the exploratory drilling, laboratory testing, and an evaluation of the foundation options for Linn County's rehabilitation of the Gilkey covered bridge crossing Thomas Creek on Goar Road. The bridge is a ±82-foot long by ±24-foot wide, four-span timber trestle structure built in 1950. The existing structure is structurally deficient with a Sufficiency Rating of 22.5. Rot has been found in some of the timber piling supporting the bridge, and the bridge deck and stringers have various degrees of weathering and/or deterioration.
The US Army Corps of Engineers (USACE), Portland District plans to construct ±6,000 linear feet of setback levee as part of the Columbia Stock Ranch (CSR) project in the Lower Columbia River Estuary. In addition to the new ±15 to 25‑foot high levee, the project includes:
- 12,000 linear feet of tidal channel excavation
- Overflow channel excavation
- Breaching the existing levee in three places
- Construction of a tide box structure
- Construction of a levee closure structure for the railroad
- Construction of access roads and haul roads
- Construction of two channels under the railroad embankment
Material from the tidal channel, excavations, plus material from a local dredge disposal site will be used to construct the new levee with balanced excavation to embankment volumes. Foundation Engineering is providing geotechnical services including site analysis, recommendations for design and construction, and evaluation of the borrow soils.

The Oregon Department of Fish and Wildlife is planning to decommission the Ferry Creek dam in Bandon, Oregon, which sprang a leak in 2014. Foundation Engineering is working with The City of Bandon to complete feasibility study for a water storage reservoir to replace the water source provided by the Ferry Creek dam.
Just after Christmas, Foundation Engineering completed the subsurface exploration for the replacement of six bridges in Astoria linking the City with the popular Riverwalk and waterfront. We are currently working on the foundation design for the bridges. The project will replace the deteriorating timber structures with modern structures that fit with the historic Astoria waterfront.
OSU Valley Football Center Expansion
Foundation Engineering provided geotechnical design and is currently providing construction‑phase services for the OSU Valley Football Center Expansion project. On January 26, 2016, while excavating for the new locker room that will be at field level, the excavation subcontractor uncovered bone-like material and immediately stopped work. Upon further investigation, it was determined by OSU archaeologists and anthropologists that the bones and bone fragments were from an ice-age woolly mammoth. The area was cordoned off and over the next 24 hours, careful excavation of the bones led by a team of OSU archeologists and anthropologists uncovered an intact woolly mammoth femur (damaged upon removal from the excavation), pelvis and hundreds of other bone fragments. In addition to the mammoth bones, bones from a camel and bison were also identified.
The geologic significance of this find is the bones were uncovered deep within the Willamette Silt deposit, approximately 12 feet below the surrounding grade. Willamette Silt is a predominately fine-grained, alluvial deposit from the great Missoula Floods that occurred over a period of ±15,000 to 12,000 years ago. Therefore, were the animals victims of the flooding or did they die prior to the flood deposits? The OSU archaeology department will radio carbon date to aid in determining the relative geologic age of the bones and stratigraphic sequence. We will keep everyone updated as the information becomes available.
Several days of rain saturated the slopes, followed by intense rainfall during the night of December 8th resulting in dozens of shallow slope failures and debris flows effecting Kalama River Road and similar roads in steep-sided valleys.
Foundation Engineering has been called in to provide geotechnical services to the Cowlitz County Public Works Department.

October 27, 2015, Oregon State University celebrated the grand re-opening of the Strand Agricultural Hall. 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.
As reported by the Gazette Times,
"it is one of the most structurally sound buildings in the state"
Oregon Field Guide featured the Lava Butte US 97 Wildlife Crossings. These unique structures provide deer, coyotes, black bears, and other wildlife with a safe passage across roads, and include guide fences to funnel animals to these safe zones. Providing an alternative to move between territories prevents wildlife from entering the roadway, endangering human and animal life. Since their installation, these crossings have substantially reduced the number of roadside carcasses, and ODOT estimates that the $1.5 million cost will be saved in 12 years of prevented collisions.
This is a an exciting project that we were proud to provide geotech for.
This upcoming Monday, October 12th, renowned expert on the Cascadia Subduction, Chris Goldfinger, will be presenting at the Corvallis Science Pub,
Goldfinger was a major resource for The New Yorker's "The Really Big One" feature article that shook the Pacific Northwest. He will be speaking on his research and the risks associated with the breaks along the Cascadia.
The City of Corvallis is replacing a four-span timber trestle bridge that spans Oak Creek in southwest Corvallis. Bridge inspections uncovered rot in the timber piling and stringers rendering the original bridge structurally deficient and load restricted. The bridge is located on SW Morris Avenue and provides local access to residences and several apartment complexes that house Oregon State University students.
The new bridge will be an 84-foot long, 39-foot wide single-span, pre-stressed concrete structure supported on 16-inch diameter, driven pipe piles. Foundation Engineering completed two deep borings at each abutment, laboratory testing, pile analysis and design, and developed recommendations for site preparation and foundation construction. Construction began in July 2015 and expected to be completed in October, 2015.
