Home to the San Francisco 49ers and venue to the Superbowl 50, Levi's Stadium is truly a majestic piece of art that focus on technology, open spaces and sustainable concept. The stadium was designed in such way that people in the stadium have a spectacular view of the playing field but also stunning views of the Silicon Valley. The Stadium was built recently and was the first NFL stadium to open with a Leadership in Energy & Environmental Design (LEED) gold rating from the U.S. Green Building Council.

Levi's Stadium Quick Facts

The stadium has a seating capacity of 68,500 and it was opened on September 14, 2014. The naming rights of the stadium cost $220 million and are valid for the next 20 years. The architect of the Superbowl 2016 venue was HNTB, which are experts on sporting arenas. The funding of this stadium was almost all private with only 12% public funding used to built the stadium, which construction cost was around $1.3 billion.

Levi's Stadium Construction Details

The 49ers stadium was built by a large group of contractors and some major milestones were achieved during its construction. Here are a few of interesting construction facts of the Levi's Stadium:

  • Stadium is LEED Gold certified
  • It has a large photovoltaic array providing energy to many areas of the stadium.
  • A living roof was also built as part of the sustainable features of the venue.
  • All of the plumbing fixtures are considered as water efficient.
  • A large portion of the material used to build the stadium come from recycled sources
  • 127,000 bolts were used to keep all structural steel in place
  • 14,000 pieces of steel were installed during the construction process.
  • The stadium has the first automatic collapsible end post in the NFL. It takes only 8 seconds to lower them to the ground and 30 seconds to raise them up.
  • The Levi's Stadium sign is 17 foot tall and 86 foot wide, sitting atop the south video board.
  •  80,000 cubic yard of lower-carbon concrete for the auger cast piles and the overall stadium structure were poured during the construction process.
  • More than 2,000 precast panels were installed in the stadium, Some of these panels were 40 foot long and weigh 35,000 pounds.
  • Concrete mixes reduced the overall carbon footprint by an estimated 23 million pounds of CO2
  • First NFL stadium to use BRB. BRB uses a core brace buckling restrained brace to improve steel performance during seismic events.
  • The construction team used an innovative process called Auger Pressure Grouted Displacement (APGD). This system allows to drill an auger into the ground and pumping grout through the hollow shaft of the auger, producing shafts of grout in the soil. The drill can reach up to 150 feet into the ground, so once it has been done the rebar cage needs to go in and it has to be filled immediately.
  • The grass, Bermuda Bandera type, requires less than 50% of water than the average sod in the San Francisco.
  • The site drainage allows for a fast movement of the water generating a dryer and stable playing surface
  • The project team embraced BIM and Integrated bridging design-build (IBDB) to deliver the project on time and on a fast-track schedule
