This upscale Hotel and Casino was built for the Agua Caliente Band of Cahuilla Indians. This project provided a number of design challenges due to its close proximity to the San Andreas seismic fault. The project consisted of a 16-Story Ultra Luxury Hotel Tower with surrounding Low-Rise Structure including expanded Casino, three restaurants and back-of-house, 28,500 square foot hi-tech conference center, 13,000 square foot spa facility and 7,700 square foot porte-cochere.
The hotel tower is a cast-in-place concrete structure with a concrete shear wall lateral system supported by a mat foundation. The lower floors were 12-inch thick mild reinforced concrete while the typical hotel floor consists of 9-inch thick post tension reinforced concrete. The typical tower column bays are 32-feet by 24-feet. The retail area consists of structural steel framing supported by conventional spread footings with a structural steel roof deck. All of the concrete was detailed per chapter 21 of ACI 318.
