A year after breaking ground on the $520 million headquarters for the State of California Natural Resources Agency in Sacramento, Calif., Turner Construction Co. has topped off the 838,000-square-foot office building one month ahead of schedule.

The State of California Department of General Services tapped Turner and partner AC Martin to serve as the design-build team for the Natural Resources headquarters in March 2018. Roughly one year after breaking ground, the partners have placed the final piece of structural steel atop the building at 344 feet above the ground. Upon completion, the structure will stand 22 stories in downtown Sacramento and hold the distinction of being the tallest building erected in the city since 2009.

Turner and AC Martin are on track to complete development of the tower by the summer of 2021. The partners have not divulged the financial details of the design-build contract. However, the State noted in the RFQ for the project that it would establish a stipulated sum of approximately $480 million to $490 million for the designated design-build team.

In addition to Class A office accommodations, the Natural Resources headquarters will feature 10,000 square feet of retail space, a health center, a 300-seat auditorium and a pedestrian plaza. Turner and AC Martin’s work on the project also includes the development of a freestanding childcare facility for 120 students and improvements to the exterior of the adjacent Heilbron House, a historic mansion owned by the State.

Government gigs

A team consisting of Arup, CO Architects and FXCollaborative are behind the design of the building, which will not only be the headquarters of the Natural Resources Agency but home to offices of the Department of Water Resources, the Department of Forestry and Fire Protection and the Wildlife Conservation Board as well.

Turner’s wide variety of clients has included a bevy of government offices of late, from the local level to the federal level. The company and joint venture partner Flatiron Group are managing the construction of a $700 million, two-concourse expansion of Denver International Airport on behalf of the City and County of Denver. Additionally, Turner is serving as general contractor for the U.S. Navy’s new San Diego headquarters, a $200 million project that reached the upper deck two months ago.
