Example Projects:

Project: Jordan Park Gabion Basket Wall

Location: Portland, Oregon

Contractor: Terrafirma Foundation Systems

This project utilized 73 HA150 helical tiebacks to support up to a worst case 20,000lb working load from gabion basket tiered retaining walls. Gabion basket wall heights ranged from 3ft to 9ft of exposed wall. Steel channel walers were used to gather load from the gabion baskets and transfer to the tiebacks.

Project:  Fort Riley, KS Building 211
Location: Fort Riley, Kansas
Contractor:  Foundation Recovery Systems

This Design-Build project will renovate historic Building 211 located in the Main Post area of Ft. Riley, KS. The facility is listed on the National Register of Historic Places Inventory. This structure was built in 1889 of native limestone. The scope includes the renovation and repair of an existing 41,062 sq ft two-story administrative building with a basement into an Education Center. This facility is currently in use but has failed or failing components including heating and air conditioning system, plumbing, electrical, and interior finishes. The historic limestone and concrete floor structure will be renovated and repaired to provide suitable modern offices, training space and classrooms, and bring deteriorated components and systems in the building up to current building codes and Life Safety standards, Americans with Disabilities Act (ADA), National Plumbing, ASHRAE Mechanical, and National Electrical Code requirements, Unified Facilities Criteria as well as DoD Minimum Antiterrorism Standards For Buildings and DA Seismic Standards.

Project:  DeSoto High School Underpinning
Location: DeSoto, Kansas
Contractor:  Foundation Recovery Systems

This project consisted of a foundation shoring along a 56 foot long section of a stepped concrete foundation with a masonry wall above to allow for excavation for construction of a basement addition to the high school.  The design incorporated 14 push piers 11 helical lateral restraints and a 350 sq.ft reinforced shotcrete wall with 23 helical soil nails.
