October 2014 41 project from the beginning. The project design was further developed, construction documents produced and construction of the new Alumni Plaza was completed by June 2014. Design Challenges The project presented some unique challenges for the designers and builders. While the deterioration of the surface was apparent, it was also necessary for the university to replace the roof membrane, roof drains and all of the drainage fill material. Permeable pavers were set directly over the new roof stone, creating a surface that drains through continuously. Given the size and very horizontal nature of the plaza, two styles of permeable pavers were selected to visually break up the scale of the space, and help define smaller gathering areas. In an effort to create more usable spaces, an area referred to as the "sun deck" was designed to provide outdoor dining space. The framing was constructed over new concrete piers poured directly on the roof, with composite decking and trim finishing. The deck drains freely to the roof stone below. The desire to include additional green space in the plaza led to creative detailing of landscape areas. As the existing roof top section varied from only 6 to 12 feet from roof deck to pavement, new landscape areas were created by installing cast-in-place concrete curbing in varying heights, allowing new soil depths between 10 and 18 inches to allow the plants to flourish in the challenging roof Top The old Garrigus Plaza surface and drainage had long ceased to properly function, the concrete spalled, cracked and in disrepair. The original design consisted primarily of concrete and brick, with minimal green space. The plaza experienced significant ponding when it rained, and winter precipitation left dangerous ice. As the signature entrance for the college, the space was long overdue for a redesign. Bottom A 52-ft. wide by 22-ft. tall steel sculpture frames the plaza. Structural engineers Brown + Kubican were enlisted to aid in the design for the new sculpture and provide structural design of the foundations for the sculpture and new lights.
