Hilton Hotel
Original Tower by B. L. Nishkian Engineering
Tower II Addition
Twenty-two story, steel frame guest room wing and remodel of existing hotel.  In addition to the hotel tower, this complex housed a column-free ballroom of 25,000 square feet.  Project was complicated by having spans over the ballroom of 120 feet in length, which in some cases were also required to support the 22-story guest room wing on top.  Estimated construction cost for total project $180 million.
