Golden 1 Center, home of the Sacramento Kings is a multi-use facility built to occupy four city blocks downtown. The arena contains a state-of-the-art practice facility with administrative offices as well as 1.5 million square feet of additional development space. It includes 475,000 square feet of office space, 350,000 square feet of retail space, a 250-room hotel, and up to 500,000 square feet of residential units.
Its design combines the indoors and outdoors featuring a glass curtainwall, airplane-hangar doors and faceted, perforated-metal cladding to mimic the Nevada mountain range and increase the flow of light through vertical glazed openings.
A key feature of the build is the roof, complete with platform top and light pipes that can be programmed by local artists and used to convey events in the arena to the public. The roof structure was formed with two large 212 ton, 314-ft box trusses and 17 smaller 40-50 ton, 113-125ft secondary trusses. Each box truss consists of 3 sections that each weigh approximately 52 tons and measure 120’ long x 15’ wide x 15’ high.
The 3 sections of each truss were pre-assembled at the fabrication facility with approximately 180 workers to ensure they fit together when assembled during the erection of the roof. Approximately 50 workers were onsite installing the roof trusses.
Transportation of the two main box trusses required a great deal of coordination. Each box truss took the trip in two legs. The first leg was from Schuff Steel facilities in Stockton to R&B Protective Coatings in Linden, California. The second leg continued from Linden to the job site.
Neither leg was a direct route due to the 17-foot height of the truss. The route needed to avoid overhead obstacles and make sweeping turns. A transport truck with a pole representing the truss segment’s height drove routes to determine where the truss could pass and where the truck would have to find another way. Segments were shipped between midnight and 5am during the week.
The project is the first LEED Platinum-certified NBA arena fully serviced by solar energy derived from a 1.2-megawatt array on its roof, and an 11-megawatt solar farm just 40 miles away. Being centrally located has helped to reduce carbon emissions for travel time per attendee and has become a major catalyst for further development of the area.
