Calverton, New York-based International Exterior Fabricators will ultimately assemble and erect the stainless steel cladding and curtain wall system at Neil Denari’s HL23 condominium project on West 23rd Street and 10th Avenue, which is aiming for a LEED Gold certification from USGBC. Recently, the firm executed a mock up of the complicated exterior system; its director of engineering, Rob Young, describes the mock up process as the “perfect way for not only the architect, owner, and contractor to become familiar with the job – and all of its different aspects – but it allows us, as a fabricator and installer, to get a feel for all the difficulties involved before actually building it.”
Mock ups are a standard part of the construction process and aim to address those difficulties in the shop, in advance of construction in the field, in order to minimize the risk of change orders or other directives that can cost the project team time and money. IEF’s Nick Mango was kind enough to forward us a photo of the mock up (see below); as you’ll recall, the curtain wall system was designed to improve the 39,000-square-foot HL23′s energy efficiency by 15 to 25 percent over code.
Other green features will include reflective roofing, a two-year green power purchasing agreement, construction waste management, and recycled-content building materials. The project team also includes interior architects Thomas Juul-Hansen Architects, LEED consultants YRG Sustainability, and construction managers T.G. Nickel & Associates. Developer Alf Naman began construction last March and should wrap up sometime this spring.
