Their challenge

The Waldorf Astoria Atlanta Buckhead, formerly the Mandarin Oriental Hotel, merges luxury hotel accommodations, multi-family housing, office space, and restaurants into one 42-story tower. The 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 60-foot saline water lap pool. The facility design presented various challenges common to buildings of this size and variety. Salas O’Brien was brought in to provide mechanical, electrical, plumbing, and fire protection design and commissioning services for the structure, including an underground parking area.

Our solution

The electrical systems our team designed 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.
