Atlanta Marriott Marquis
Scope/Solutions
The Atlanta Marriott Marquis is a fifty-four story building built in 1983 and designed by John Portman. The building facade consists of exposed cast-in-place and precast concrete with sliding glass doors at each guest room. The Atlanta Marriott Marquis experienced falling pieces of concrete and water leakage into the guest rooms The hotel was very concerned about guest and pedestrian safety, the impact of water leakage on customer satisfaction, and how to improve the long-term durability of the facility.
SGH investigated the exterior wall issues and identified spalling concrete at the exterior balcony and railing-to-slab connections, deteriorating precast concrete balcony railings, cracking and spalling concrete of both cast-in-place and precast, and water leakage through the guest room sliding glass doors.
We evaluated the causes for the deterioration, recommended immediate repairs, and provided conceptual strategies for long-term repairs to extend the useful life of the structure. SGH provided corresponding life-cycle and cost estimates of each of long-term repair options. We then designed and administered repairs, including removal of the faux balconies, concrete repairs to remaining facade elements, and an elastomeric coating of the entire exterior.
