The project consists of a full service Hilton Hotel located at the intersection of 5th Avenue and Park Street in Des Moines, IA. The simple, modern exterior materials and composition are inspired by agrarian landscape and are enhanced by unique lighting elements. Hotel amenities will include 330 guest rooms; a 10,000-square-foot ballroom with prefunction and outdoor terraces; 4,000 square feet of breakout meeting rooms; a full-service kitchen; restaurant with outdoor seating; lobby with bar; tech lounge; swimming pool; and fitness center.

To renovate the 35,000 sq. metre facade, the Freyssinet teams applied a range of solutions, including cathodic protection of the reinforcing bars and application of a waterproof silane surface treatment.

Rejuvenating the building while minimising disruption for occupants

Since the building remained occupied during the project, a major effort was made to minimise disruption for local residents, including encapsulation of the work areas and specially developed work platforms. Overall, the noise level was reduced by 25 dB. The face lift restored the iconic building to its former glory as part of the Sydney skyline.
