Project Details

Oakland Army Base Redevelopment | Oakland, California

Situation

In 2013, GBI formed a joint venture with Turner Construction, and Flatiron Construction for the redevelopment of the decommissioned Oakland Army Base, also known as the Oakland Army Terminal, which is located on the waterfront near the San Francisco-Oakland Bay Bridge. This design-build project involved 150 acres of site development and approximately five miles of new and refurbished roadway infrastructure. The former Army base had several areas where hazardous chemicals had impacted the soil and groundwater; therefore, an extensive environmental cleanup was required. As a result, a Remedial Action Plan (RAP) and a Risk Management Plan (RMP) was prepared for this project.

Solution

The scope of work included 150 acres of demolition, along with the installation of 15,000 linear feet of large-diameter storm drain and 15,000 linear feet of deep sanitary sewer. The scope of work also included the excavation and profiling of approximately 100,000 cubic yards of potentially contaminated soil, the lime treatment of approximately 50,000 cubic yards of bay mud, the installation of wick drains, and the construction of surcharge building pads, which included deep dynamic compaction building pads. Additionally, roughly 250,000 cubic yards of clean soil was imported to the site, and 15,000 linear feet of new roadway was constructed. The project also involved the treatment and discharge of approximately 100,000 gallons of groundwater containing volatile organic compounds (VOC) and petroleum hydrocarbons. Among other strategic solutions, detention basins were created for temporary stormwater containment, and above-ground fused high-density polyethylene lines were used as a conveyance system to carry water from the basins to the treatment plants. Additionally, a mobile crusher was set up to process oversized cobbles into 4-inch minus material, and GPS-guided equipment was used to maintain constant control of the work. The site’s proximity to the San Francisco Bay presented geotechnical and environmental challenges, but the project team swiftly navigated every challenge and successfully completed the project in 2018.
