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 Iowa’s 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.
The site is designed with 129 subsurface parking stalls and a surface parking lot with 36 stalls. A skywalk will connect the hotel to the downtown skywalk system.
In the case of the Hilton Des Moines Downtown, 84 percent of work performed for the bathroom PODs was in a prefabrication shop. This not only improved the oversight and reduced the safety risks associated with each build component, but it allowed the Weitz project team to plan for the small batch delivery and installation, eliminating congestion on-site and material trip hazards with products being stored on wheels. In total, prefabricating the bathrooms off-site diverted 15 tons of trash from the jobsite to create safer and cleaner working conditions.
After topping out on May 12, 2017, the project team flipped the building from a structure to dry wall installation starting in less than eight weeks — a 10-week difference compared to conventional projects. Upon setting the first 50 bathrooms PODs to sequence and establish flow, it only took 11 days to install the other 250 prefabricated PODs. This significantly accelerated the schedule of the project by eliminating 17 weeks of construction waste from the project schedule by installing the 300 prefabricated bathrooms in just three weeks.
The client benefited from having prefabricated materials built consistently with tighter tolerances and coordinated to withstand lifting, moving and transportation. This led to a more consistent, quality installation and fastening. Specifically, by utilizing factory controls, Hilton received a tighter grout joint in the prefabricated bathrooms, which it deemed a four-star hotel quality product.
