>> Commercial office properties have always had to contend for tenants as a part of doing business, but increasingly, existing buildings are facing stiffer com - petition from new office properties offer- ing integrated amenities packages that go way beyond the lobby coffee shop. As a new generation of employees enters the workforce, employers are challenged to secure leases that provide more than simple office space, instead offering an at - tractive combination of recreation, retail, and relaxation options that feel more akin to a resort than a workplace. In the case of Prudential Plaza, a 41-sto - ry structure in Chicago built in 1955, the challenge for the building owners was to offer new value in a building originally designed to respond to a workforce that no longer exists. Prudential Plaza's own - ers envisioned a top-to-bottom rehabilita- tion, crowned by a 13,000-square-foot amenities deck on the 11th floor. Certainly the idea of a gorgeous ten - ant recreation and lounge area would appeal to most, however few outside of the construction industry would appreci - ate the immense challenge of adding this type of space on top of a 60-year-old roof. However, project manager Ishmael Joya, with 15 years of experience specializing in green roof construction, quickly under - stood the complexities of the situation. "Prudential Plaza is a classic figure in Chicago's skyline and the first time we walked the project it was clear that the four-and-a-half-inch thick roof deck was going to present some design and con - struction challenges," remarked Joya, (who) realized that adding what is essen - tially a mini-park to a very thin structural surface was going to require out-of-the- box thinking. "In any roof deck renova - tion, it's critical to reduce the weight of the building materials, because the build - ing is only designed to support a maxi- mum amount of weight and that can't be compromised," he said. Fortunately, Joya had already had a strong positive experience with ACH by Sean O'Keefe 10 LC DBM Top In order to attract tenants, the Pru- dential Plaza, a commercial office property in downtown Chicago, went through an $85 million rehabilitation that included a 13,000-square-foot rooftop deck, which was installed on top of Foam-ControlĀ® EPS Geo - foam by ACH Foam Technologies.
