The tall building market continues to thrive, both in the US and certainly around the world. The number of tall buildings constructed around the globe has increased exponentially over the past decade by over 350%. In 2017, a record 144 buildings 200 meters or taller were completed, spread across 23 countries. Predominant structural materials for tall buildings being built around the world are composite (steel and concrete) and all-concrete, although the use of timber as a major structural element in towers is quickly gaining traction.
First and foremost, our approach to the structural design of tall buildings is fundamentally based on our partnership with the Architect. The optimal structural design often lies somewhere in between the architectural vision, an efficient structural design, and local construction practices and materials. Accordingly, we recognize, embrace, and actively pursue the opportunity to collaborate with both clients and builders as early and as often as possible during the design phase.
Major tall building projects are often difficult to actually be built and ‘survive the gauntlet’ of required capital and market sensitivity. Walter P Moore’s approach to design and experience with key constructability issues of tall buildings results in economical structural systems that make these kinds of projects viable. To that end, we understand and appropriately address key tall building issues ranging from performance-based design to an optimal structural core layout.
Walter P Moore has designed over 20 towers that are 47 stories or taller, and 34 towers that range from 115 meters (378 feet) to 400 meters (1316 feet) in height. We have significant experience designing a myriad of tall building structural systems, including outrigger-braced cores with and without belt trusses, diagrids, and tube systems. By leveraging sophisticated parametric modeling techniques, we work in real-time with our clients to provide design options and ultimately identify optimal structural solutions.
