Perini Management Services, Inc. is the prime contractor for the seismic strengthening of The Ahwahnee Hotel at Yosemite National Park, California. The Ahwahnee Hotel is a year-round landmark hotel with 97 guest rooms and an awe-inspiring elegance and rustic architecture designed to blend in with the granite backdrop of the Yosemite Valley wall. Listed on the National Register of Historic Places in 1977, it was declared a National Historic Landmark in 1987. The grand Ahwahnee Hotel originally opened for business in 1927 and has remained an architectural crown jewel in the national park system. This project will execute the Ahwahnee Comprehensive Rehabilitation Plan (CRP), a phased, long-term program of comprehensive repair and upgrades to bring The Ahwahnee into compliance with current codes, seismic safety standards, and accessibility requirements. All renovation work will follow strict guidelines with regard to preservation of the historical elements of the facility.
