Construction Begins on New State of California ‘Swing Space’ Office Building

Monday March 18, 2019

The corner of 10th and O streets in downtown Sacramento was buzzing with construction activity as Hensel Phelps began sitework for the California Legislators’ “swing space” annex building last week.

Working closely with the State of California Department of General Services (DGS), construction manager Gilbane, and design-build partners HOK and Dreyfuss + Blackford, the project has gone from planning to construction in just eight months. Hensel Phelps, as the general contractor, is leading the progressive design-build team for the $423.6 million project.

“I am excited to see this project begin construction; overall, the project fits DGS’ forward-thinking outlook toward building,” said DGS Director, Daniel Kim. “This is the state’s first Progressive Design-Build project, which allowed us to reduce the overall schedule by 18 months. I am proud to provide the Legislature and the Governor’s Office a highly sustainable working space that promotes wellness, future flexibility and safety.”

The fast-track project will serve as a temporary home to the Governor and Legislators, while the existing 67-year-old Capitol Annex is rebuilt to meet current codes and address space constraints.

“Hensel Phelps is excited to be a part of the solution to help the State of California move forward in its goals,” said Hensel Phelps District Manager and Vice President, Jim Pappas. “We see DGS as true partner in this collaborative process, and together we will get this important project built for the Legislature and Governor’s Office.”

The new “swing space” annex building will rise 10 stories above 10th and O streets, and house 472,000 square feet of office space for approximately 1,250 state employees. The building is designed to be net-zero for both energy usage and carbon emissions, and is slated for completion in 2021.
