Oakland Army Base – Oakland, CA
Brief Description of Construction Project This $153M project was the first phase in converting 300 acres of the Army’s old 1800 acre Oakland logistics facility to civilian use as a multimodal seaport logistics complex with the partial intent “to shift traffic from trucks to trains on site and thereby reduce truck trips through cities within Alameda County to the Central Valley which will help to improve air quality, neighborhood and roadway safety” (quote from City of Oakland website). Our work on the project ran from October 2013 to May 2019
The project scope included:
- Deconstruction and demolition of existing army warehouses and other structures
- Removal and replacement of existing electrical, communications, storm drain and sanitary sewer utilities with new infrastructure. Some of the more significant improvements included:
- Lift stations
- Outfalls in the tidal zone
- Storm sewers and drain inlets.
- New and rebuilt streets, sidewalks, parking areas and bike paths.
- Compaction in preparation for the Phase II structural foundations using:
- Surcharge compaction with wick drains and
- Deep Dynamic Compaction (DDC).
- Landscaping and irrigation
- Street lighting and traffic signals
To make matters more interesting, over the course of this project a mating pair of burrowing owls found quiet spots within the project boundaries to fledge new generations of little hooters.
