Five of the current most innovative techniques and safety practices utilized to erect built structures were exhibited in the Construction session, chaired by Andy Campbell, Project Manager, New Markets, Multiplex, Presentations began with New York’s 56 Leonard, a building with “Jenga-like” cantilevered floors, that Keyvan Kazemi, Project Manager, Alexico Group, notes is “at the very edge of what is structurally possible. After all there are many buildings with cantilevers, but not many buildings with hundreds of cantilevers.” A custom stackable perimeter screen system was used for the installation of the tower’s 266 balconies and 13 outdoor terraces to ensure worker safety and protection.
The design and construction of a tower with a suspended perimeter, 111 Main, was enacted to accommodate the adjacent theater building with which it shares a basement floor and lobby. Using a lower hat truss composed of structural steel, the tower hovers over the four-story theater without imposing perimeter tower columns. “A very visible benefit of this design was the removal of 18 columns at ground level, which creates a stunning jewel box of a lobby,” said Kory Jardine, Construction Manager, City Creek Reserve, Inc. The lobby features a 35-foot-high and 10-foot-wide single pane glass panel, which is outfitted with an exposed glass hinge to connect it to the remainder of the tower. This set-up allows it to withstand significant, localized seismic movement.
461 Dean is the world’s Tallest Volumetric building, consisting of prefabricated modules that were constructed entirely off-site in the Brooklyn Navy Yard, and transported during the night in groups of four. The 363-rental unit building achieved LEED © Silver certification and contains modules that are completely outfitted with MEP components, as well as pre-fab bathroom pods and a pre-attached façade, ensuring superior waterproofing. A great leap for volumetric construction, 561 Dean topples expectations for how high modular, dense and attractive multi-unit residences can be. “This isn’t what you’d typically expect of a modular construction—an extruded rectangle with the same LEGO© block done over and over again,” said David Farnsworth, Principal, Arup, who presented alongside David Edelson, Project Manager, Turner Construction Company “We actually had 36 different plan positions on the biggest floor. Modules vary in shape and size from trapezoidal to triangular to rectangular.”
The world’s first use of a Closed-Cavity Façade on a high-rise commercial tower is found at The EY Center, a golden-hued, timber-encased office building that was intended to warm up the traditional workplace with natural materials. The EY Centre enjoys a triple-glazed, super-clear façade that is outfitted with automated timber blinds, which enable it to enjoy a 30-40% energy reduction, all without external sun shading, explained Jason Vieusseux, General Manager, Design Management & Construction, Mirvac Construction and Tom Waters, Project Director, Mirvac Group. The best thing about The EY Center is the sense of place,” said Vieusseux. “The vision was to use natural materials, timber and stone to make it more inviting.”
Dexiong Weng, Deputy Chief Engineer, Ping An Life Insurance Company of China, and Florence Chan, Director, Kohn Pedersen Fox Associates, gave a detailed presentation on the Ping An Finance Center, a supertall in Shenzen at 599 meters that pushed boundaries in construction technology. The project employed not only innovative solutions but also efficiency, speed and safety—the tower was erected without a single casualty. “To give you an idea of the speed, the actual construction period was eight years,” said Dexiong Weng. “So, on average, the tower was rising one meter per day.” The Ping An Finance Center, which required a massive excavation for its foundation, wanted to minimize disruption to the urban fabric, including a nearby metro station. Their innovative cross-lot bracing system with two large-diameter rings allowed for extremely minimal rearranging of the metro line, and reduced construction time by 10 percent. The approach to the Ping An Finance Center approach represents a model for supertall construction that is swift, stealthy and safe, even in extremely dense, highly-developing areas.
The winner of the 2018 Construction Award was the EY Centre.
