NEW YORK CITY – On June 9, the CTBUH New York Chapter in collaboration with the CTBUH Young Professionals Committee (YPC), held the first of its lecture series, “Future of Construction,” on the topic of “Manufacturing Buildings.” The overall purpose of the series is to explore innovations in the construction industry, analyze how the demands on construction have changed – due to urbanization, sustainability, population growth, project complexity, and new technologies – and finally, look at some of the ways in which the industry has responded to these changes. 
The first installment focused on modular construction through a case study of 461 Dean Street, also known as B2 BKLYN. The 32-story, 106-meter residential tower is the tallest volumetric modular building in the world and is unprecedented in terms of the extent to which construction is completed off-site. Steel modules are fully fitted out in the factory, complete with interior finishes, MEP systems, and cladding. Modules are then brought to site where they are connected and stacked together. The three event panelists, who are also all stakeholders in the project, described it from their unique points of view, starting with Forest City Ratner Vice President Adam Greene.

Greene spoke of how his company decided to use modular construction on the project because of its various advantages. He shared that they were originally inspired by a timelapse video of the 19-day construction of a tall building in Changsha, China. Despite some legal difficulties during construction, the developer was pleased with the integrated design and construction process.

Taek Kim, Architect, SHoP, next discussed the process from an architectural point of view. The interior experience, he described, should seem like a jointless connection between modules in multiple bedroom units. Kim also noted that some aspects of the kitchen and bathroom had to be modified for quick factory reproduction, and then transported from a factory in Virginia to the fit-out factory located locally in Brooklyn.
The panel (Adam Greene (L), Vice President, Forest City Ranter; David Farnsworth (M), Principal, Arup; Taek Kim (R), Architect, SHoP) discussed their unique points of view about building constructions.
In his presentation, Arup Principal David Farnsworth shared the structural scheme of the modules, which transfer loads in one standardized structure for each module. Arup had to specify welding and bolting from outside the modules on–site, so that construction workers would not need to go inside the finished interiors during installation. Plumbing risers are located to the hallway side of the units for access, and fire-proofing strategies include four layers of gypsum board.

After the presentations, a lively panel discussion moderated by Autodesk Incorporated Vice President and Architect Phil Bernstein commenced. The CTBUH New York Chapter and the CTBUH Young Professionals Committee are looking forward to the next exciting lecture of this series.
