Blackstone Hotel

TGRWA provided structural engineering services for the renovation of the existing historic 1909 hotel on Michigan Ave. The 300,000 sq. ft., 24-story, 335 guestroom Blackstone Hotel is a Marriott Autograph Collection hotel brand. The famous hotel had been vacant for many years before the renovation. The existing clay tile and steel framed structure includes new stairs and elevators, a new loading dock, and a new penthouse. Renovations included various structural repairs and modifications, new MEP systems, and amenity spaces that were needed to bring the hotel back into service.
