The DaVita World Headquarters is planning an expansion in downtown Denver, Colorado! Swanson Rink provided mechanical, electrical and plumbing design for the DaVita headquarters back in 2012, and is now providing engineering design for the new 16 Chestnut office building, where DaVita will occupy 11 floors of the 410,000-square-foot building. 16 Chestnut is set to be complete in October 2018 and will house up to 1,200 DaVita employees.
