AECOM (legacy Shimmick) is performing the BART Transbay Tube Retrofit project, comprising the installation of a 3.6-mile concrete tube steel lining and construction of a new water pumping system.

In addition to acting as the general contractor for this project, we are self-performing the electrical work through AECOM Civil Construction specialty contractor, SCCI Electric.

The project is scheduled for completion in 2021.
