Case Study: Commercial Redevelopment—Soil Nailing

Client: Regional automotive dealership Location: Kitsap County (Bremerton), WA Contact for geotechnical projects: John Peterson

Project Background & Challenges

A client sought to redevelop an 11-acre property for commercial reuse. Because this site has severe physical constraints — steep slopes and nearby public rights-of-way — a variety of geotechnical solutions were required. The site required regrading, excavation and fill (25,000 cubic yards), and construction of a support-wall system using soil-nailing techniques. It features three commercial buildings and staged, graded benches.

Solution

Aspect’s technical support for this project began during the design phase and continued through the construction phase. Our work included geologic site exploration, geotechnical engineering design, and on-site construction management. We developed design criteria for road pavements, building foundations, and detention ponds, as well as support-wall, drainage, and fill-compaction systems. The use of the soil-nail support wall was instrumental to the project’s success.
