Levi's® Stadium, in Santa Clara, California, will be the new home of the San Francisco
49ers.  The venue will have 1.85 million square feet, seat approximately 68,500, and
will feature 165 luxury suites and 8,500 club seats.  The new stadium was designed
by HNTB, an architectural firm headquartered in Kansas City, Missouri, with a focus 
on creating a multi-purpose venue with top priorities on the fan experience and 
green technology.  Levi's Stadium is designed as an open stadium with a natural 
grass field.   The structure takes advantage of the Silicon Valley climate and will be 
predominantly open and airy, while also environmentally friendly.  The majority of 
the luxury suites are on one side of the field, which puts the fans in the upper deck 
closer to the action.
Turner Construction, San Jose, California, was awarded the contract, Blue’s Roofing, Milpitas, California, was selected as the roofing and waterproofing contractor, and Jensen Landscape, San Jose, California, provided landscaping for the project.  The project started in July 2012 and was completed in July 2014, just prior to the opening preseason game played in August.
Tim Blue, of Blue's Roofing, stated, “Our original contract was for:  400 squares of below grade retaining walls using American Hydrotech; 4,400 squares of split slab waterproofing with American Hydrotech; 400 squares of Garden Roof® membrane using American Hydrotech and Dow(TM) insulation; 1,100 squares of Firestone TPO roofing over tapered insulation installed to 1-120; as well as sheet metal flashings for the TPO roofs.  Later on, the contract was expanded to include:  3,500 squares of LymTal IsoFlex® urethane coating at the lower and mid-bowls seating areas; caulking of the joints in precast seating at all seating areas; pavers and landscaping at the green roof; bead blasting followed by LymTal vapor barrier and coating over all split slabs; Kemper waterproofing in steel gutters; and GacoFlex® LM60 waterproofing system in two water tanks."  The final contract almost doubled the original bid.
Blue added that, “We had 51,000 direct labor hours on site in addition to subcontracting the sheet metal, caulking, and landscaping.  At our peak we had 25 men working in four crews.  Carl Boyer was our full-time superintendent on site for two years.  Both Carl and I had weekly meetings with the architect and general contractor to work out design details for the first six months of the project.”
American Hydrotech, Inc. is a developer and distributor of waterproofing and roofing products including the Garden Roof Assembly installed in Levi's Stadium.  American Hydrotech materials can also be found on more than 60,000 sq.ft. of below-grade vertical walls throughout the stadium.  "We are thrilled to be part of such an exciting arena project," said Dennis Yanez of American Hydrotech.  "Our Garden Roof Assembly and other American Hydrotech technology will perform for years to come and continue to underscore the arena and city's commitment to sustainability and modern design."
Jensen Landscape took on the task of turning the Garden Roof into a true garden.  According to Jake Cacciato, foreman at Jensen Landscape, "The logistics of the job were demanding due to the location on the roof, as well as the highly challenging job of drainage."
The 49ers first football game was played at Kezar Stadium in San Francisco in August 1946.  They continued to play there until the NFL Championship game in January 1971.  The following season they moved to Candlestick Park, where they played through the 2013 season.  After 42 years, it was time for something bigger, better, and high-tech.  Unique features of the facility include:  the green roof atop the suite tower on the west side of the stadium; three solar bridges connecting the main parking area to the stadium; accessible public transportation and bike path; wood used in the Citrix Owners Suites is reclaimed from a local airplane hangar at Moffett Field, Mountain View, California; reclaimed water will be used for both potable and non-potable uses such as the playing field irrigation water; and the concessionaire is working with local suppliers to fulfill its farm-to-table menus and will be composting and recycling as much as possible.
By all accounts, the state-of-the-art design and hard labor was well worth the effort.  The fans attending the first game in August were easily as enthralled with the modern, high–tech stadium as they were with the game.  Levi's Stadium will be a multi-purpose facility with the flexibility to host a wide range of sporting events including soccer, college football, motocross, as well as concerts and civic events.  To top it all off, the 49ers are looking forward to hosting Super Bowl 50 in February of 2016.Cover_Story_files/WR%20Calendar%209.12.doc
