Westin Riverfront Resort & Spa

Avon, CO

Located at the base of Beaver Creek Resort, the Westin Riverfront Resort and Spa has 291 residential units, a spa and fitness center, full service restaurant, meeting facilities, offices and underground parking. The facility includes direct access to the Riverfront Express lift serving Beaver Creek Mountain, along with retail, and ski storage and rental. This project received LEED® Silver certification; the first Colorado hotel to achieve this status.

This project required a unique installation system that ultimately resulted in a patent for Wells’ design. Based on the understanding that the floor depth of the building needed to be shallower than typical depths for precast double tee floors, Wells Denver designed a system that minimized floor depth by using a 10” thick rib slab plus 4” of topping for a total depth of 14”. This was achieved by designing the floor slab, beams, and column capitals to the 10” thickness which allowed for a clean structure and no dropped beams.

In addition to the successful installation of a unique system, construction in the mountains continued throughout the winter months, generally a challenge for cast-in-place and steel construction, by using precast.

Precast Solution

This project was successfully converted from a cast-in-place structure to a precast structure late in the design phase.  Wells Concrete developed a thin structure solution to compete with cast-in-place post-tension structures in hospitality applications.  20” precast columns incorporated 12” deep integral capitals to accept 10” precast beam slabs.  10” deep rib slab units framed into the beam slabs.  Unlike typical precast framing, the beam slabs and rib slabs utilized cazaly hangers so the entire framing assembly with topping flushed out at 14” deep.  Precast concrete framing allowed the project to be erected in the middle of winter keeping the project on schedule.
