The CEBAF 12 GeV Upgrade project requires 80 new 7-cell SRF cavities incorporated into 10 new CW cryomodules providing >100 MV each. The full complement of cavities has been delivered. A streamlined production process has been implemented to turn these into qualified 8-cavity strings. Although not strictly required to meet project requirements, light electropolishing of these cavities has become standard and yields consistent performance exceeding requirements, often equivalent to ILC aspirations. The applied process will be described and the performance testing results summarized to date. JLab also has a major construction project underway which will fully renovate all SRF research, fabrication, processing, cleanroom, and assembly facilities. This “Technology and Engineering Development Facility” (TEDF) Project was launched in 2010 and will run through 2012. The majority of the SRF facilities will be consolidated in a new building with 30,000 square feet (3300 square meters) of workspace attached to the existing Test Lab. This purpose-built facility integrates fabrication, chemistry, and cleanroom suites and cryomodule assembly lines for convenient, yet flexible operations serving multiple DOE projects in parallel. The facility plans and progress status will be presented.
