Mandarin Oriental Hotel

The Mandarin Oriental Hotel merges luxury hotel accommodations, multi-family housing, office space, and restaurants into one 42-story tower. The finished 616,000-square-foot building provides both guests and tenants with comfortable, excellently designed spaces to live, work, and relax.

Salas O’Brien provided mechanical, electrical, plumbing, and fire protection design and commissioning services for the structure, including an underground parking area. The finished live-in space comprises 80 condominium units, with the hotel comprising 127 rooms, multiple restaurants, a 24-hour service kitchen, and seven ballrooms as well as a luxury spa, state-of-the-art fitness center, yoga studio, and indoor pool.

The facility design presented various challenges common to buildings of this size and variety. The completed electrical systems include 16,000 amps of power sourced via four electrical services. Submetering systems service the hotel and each residence, restaurant, and office area—keeping each facility running smoothly and efficiently. The life safety system includes a 750kw generator located in the underground parking deck—securely protected from combustion, exhaust, and fuel spill hazards by special provisions in the systems design.
