The Oregon Region is currently working in the Portland area on the Bridge Point I-5 project, which is located about five miles west of Portland International Airport. This project is in partnership with Sierra Construction. GBI has worked with Sierra Construction over the years on various projects, including the Portland Portal projects and Project Piper. Bridge Point I-5 project was split into two phases: Phase 1 is $9.5 million; phase 2 is $10.2 million. The project is expected to be completed in the fall of 2020.
The project is located on a 32-acre site and sits atop an old landfill. Once complete, it will have two distribution warehouses that will total 667,500 SF. The first phase of the project included the demolition of 12 steel buildings, crushing of 32,000 CY of concrete, importing of 283,000 CY of soil, 1.48M SF of geogrid, and 83,000 CY of cement-treated soil. Once all of the surcharge is complete, the site will require the placement of 90,000 CY of cement-treated soil, 10,000 CY of structure excavation, and the digging, laying, and backfilling of more than 50,000 LF of pipe. The second phase of the project will include all of the site grading and utilities for the project.
The project has presented a number of challenges, including the difficulty of importing 283,000 CY of dirt from 12 different sites and working with 83,000 CY of concrete-treated soil with a minimum 300 PSI compressive strength. In addition, the project team has had to contend with landfill gases; surcharge sequencing; importing more than 2,500 CY per day; and waiting for good weather to dry and place dirt.
GBI was honored as Sierra Construction’s subcontractor of the year for 2018 and strives to be their “contractor of choice.”
