The octagonal tower geometry uses light and shadow to define the form while bringing practi- cality to the construction. The team considers the “diamond geometry” solution to be aesthetically superior to the modified cone and more efficient in construction. The tower cross-section is a great example of form meets function and exemplifies the total architecture perspective of design and construction. Moving forward Many technological and performance innovations were achieved during the design and construction of the Gerald Desmond Bridge Replacement Proj- ect, of which only a very few have been touched upon here. The end result is a structure that suc- cessfully rationalizes performance, maintenance, aesthetic and environmentally efficient objectives into a best-fit product, to the benefit of all. MATT CARTER is a Principal in Arup’s New York office, and serves as the Bridge and Civil Structures Skills Leader for Arup’s Americas region. He has 23 years’ experience in the conceptual and detailed design of long span and complex bridge structures in North America, East Asia, Europe, Africa and Australia. Notable projects include major cable stayed bridges such as the Samuel de Champlain Bridge in Montreal, Gerald Desmond Bridge Replacement in California, the Queensferry Crossing in Scotland and Stonecutters Bridge in Hong Kong. Through his work on major bridge projects, Matt has gained significant experience in the seismic and aerodynamic design of bridges and ship collision risk. In recent years, he has worked primarily on design-build projects and public private partnerships with both owners and contractors as clients, gaining unique insights by working from different perspectives. JOSH MATTHEIS is an Associate Principal in Arup’s Los Angeles office. He has 17 years of experience in design and design management of large rail and roadway turn-key design and build contracts. After working for international design firms and contractors, his experi- ence is balanced between both. Josh enjoys leveraging this experience to create optimized and integrated designs that provide value to all parties. Recent projects include design and design management work on the Gerald Desmond Bridge project at the Port of Long Beach, followed by the Port Miami Tunnel project and the Gautrain Rapid Rail project. Typical design activities on these (and previous projects) include alignment optimization, selection of structure types, development of adapted construction methods and detailed design production in collaboration with state, municipal and county agencies.
