Partner's Group Headquarters

Location: Broomfield, CO


Overview: An office campus consisting of two multi-story office buildings was constructed in the Interlocken Subdivision in Broomfield, Colorado. This site presented geologic hazards and geotechnical concerns including very highly expansive soil and bedrock with estimated ground heave of up to 18 inches, and potential slope instability.


CTL provided recommendations to support the buildings on deep foundations.  We also provided support of excavation (SOE) design consisting of anchored solider pile and lagging to facilitate safe excavation within the property boundaries. Our value engineering approach saved the owner cost and reduced risk of poor foundation performance.

Services Provided: Geotechnical Investigations, Retaining Wall Design, Fill Compaction, Foundation Installation Observation, Retaining Wall Construction Inspections and Observation, Steel Inspections, Weld Inspections, Concrete Testing, Fireproofing Inspections, Pavement Design.

Steilhang Hut

Arapahoe Basin Ski Area’s newly added Steilhang Hut was completed for the 2021 ski season. A warming hut complete with restrooms near the 13,050-foot summit on the Lewanee Face, Steilhang means “steep slope” in German. Along with soils work, foundation observation and geotechnical testing, the Summit team designed the septic system, which is among the highest in the country, using an infiltrator system with a sand filter and composting toilets.

National Jewish Center for Outpatient Health

CTL|Thompson performed geotechnical engineering services and environmental engineering consultation, in addition to construction observation and materials testing. Additional engineering consultation was needed when they constructed the Sky Bridge and it’s stairwell adjacent to the existing hospital. The new five-story Center is designed to help serve increasing numbers of children and adults, while also providing additional space for research, education, and other clinical services.

CSU Health and Medical Center

CTL|Thompson performed a geotechnical investigation and COMT services for the 113,000 square-foot, four-story medical building that houses a range of services to Colorado State University faculty, staff, and community members. The center is located at the southeast corner of Prospect and College in Fort Collins. The medical center is a 113,000-square foot, four story building with a partial basement.
