Miro provided structural engineering for the Ritz Carlton Highlands Hotel at Northstar located near Lake Tahoe, California. The hotel consists of a 407,000 SF building, which includes a six-story hotel portion and a separate four-story parking garage and conference center. The hotel portion is framed with structural steel and the high seismic loads are resisted by steel buckling-restrained braced frames. The parking garage and conference center is a post-tensioned flat plate structure with an elaborate long-span steel roof covering the open ballroom areas. The project posed several design challenges as it is located in Seismic Zone 3.
