The Century Plaza Hotel opened in 1966 in the Century City neighborhood of Los Angeles and had been marketed as the “World’s Most Beautiful Hotel”. The iconic building was the setting for numerous high-profile events and has hosted President Nixon, President Johnson and served as President Reagan’s “Western White House” in the 1980’s. In 2008 the new owners announced plans to demolish the hotel, but in April of 2009, The Hotel was added to The National Trust for Historic Preservation’s list of the eleven most endangered historic places in America and in 2010 the developer announced that it would renovate the building. The retrofit of the building coincides with the construction of two new 46-story towers. This presentation will focus on the retrofit of the main building (due to be complete in the spring of 2019) and how the project has proceeded in the field. We will discuss the decision process leading to the use of buckling restrained braced frames (BRBFs) in combination with conventional steel and over $2.5 million dollars’ worth of fiber reinforced polymer (FRP) strengthening. The thin profile and light weight of the FRP systems was critical to achieve the design goal given that it was essential to minimize the added mass to the building. The detailing for the beams, slabs and columns was unique given the need for innovative anchoring details and fire resistant finishes. The audience will learn how this unique approach allowed the owners to achieve their vision while strengthening and preserving this historic site.
