Project Details

Bridge Point I-5 | Portland, Oregon


The Bridge Point I-5 project involved the construction of two industrial tilt-up distribution centers totaling 677,000 square feet. GBI’s scope of work for this project included the clearing and preparation of the 37-acre site, which is located roughly five miles from downtown Portland.


The project site was a former landfill, so the initial scope of work included the demolition of 12 existing steel buildings, along with the crushing of 32,000 CY of concrete. Additionally, GBI imported 283,000 CY of dirt, 83,000 CY of cement-treated soil, and 1.48M SF of geogrid. Once the surcharge was complete, GBI placed 90,000 CY of cement-treated soil and completed 10,000 CY of structure excavation. GBI also dug, laid, and backfilled more than 50,000 LF of pipe. The second phase of the project included site grading and utility installation. GBI successfully navigated the challenge of importing 283,000 CY of dirt from 12 different sites and working with 83,000 CY of concrete-treated soil with a minimum of 300 PSI compressive strength. The GBI project team also had to contend with bad weather, surcharge sequencing, and the presence of landfill gases.
