East Boston, MA Boston Logan International Airport鈥檚 new, 10-story West Garage Extension features an attractive, kinetic exterior to distinctively screen the facility. Designed by Arrowstreet Inc. and manufactured by EXTECH, the fa莽ade system consists of more than 48,000 aluminum flapper panels that move in response to wind currents. Each flapper panel was finished by Linetec in Class I clear anodize.
The 6-inch square curved flapper panels are set within 353 extruded aluminum framing support assemblies that span eight stories high by 290 feet wide. Subjected to 130 mile per hour winds to test system resiliency, the system鈥檚 anodize finish also contributes to its durability. Class I coating is a high-performance anodic finish used primarily for exterior building products and other products that must withstand continuous outdoor exposure.
Turner 杏吧原版 Co. served as the general contractor. 杏吧原版 on the 68,880 s/f building started in June 2015. Glazing contractor, Ipswich Bay Glass Co., began installing the dynamic fa莽ade in November, and worked through the winter to complete the exterior in Jan. 2016.
Before finalizing the fa莽ade design, EXTECH provided Arrowstreet with several mock-ups for the Massachusetts Port Authority鈥檚 (Massport鈥檚) review and approval. The self-supporting Massport owns and operates Boston Logan International Airport, and receives no state tax money to support its operations or facilities. In the last decade, Massport and its airline partners have invested more than $4.4 billion to build a new runway, roadways, terminals, taxiways and garages.
Massport relied on Arrowstreet to lead a multidisciplinary team that evaluated and integrated the new garage within the existing Central Parking, walkways and adjacent terminals. Situated over the existing Hilton Hotel parking lot, it is the airport鈥檚 tallest parking structure and offers 1,700 more parking spaces. The resulting garage optimizes the experience for passengers and its dynamic fa莽ade enhances the view for the traveling public and visitors of the nearby 9/11 Memorial and Hilton Hotel.
The project team consisted of: owner: Mass. Port Authority; architect: Arrowstreet Inc.; engineer: WSP | Parsons Brinckerhoff; general contractor: Turner 杏吧原版 Co.; fa莽ade 鈥� manufacturer: EXTECH/Exterior Technologies, Inc. and fa莽ade 鈥� installer: Ipswich Bay Glass Company, Inc.
鈥淎nodizing successfully combines science with nature to create one of the world鈥檚 best metal finishes. Because it is an integral part of the substrate, the anodic coating provides excellent wear and abrasion resistance with minimal maintenance,鈥� said Linetec鈥檚 senior marketing specialist, Tammy Schroeder, LEED Green Associate.
She said, 鈥淐hoosing clear anodize to create the unique fa莽ade for Logan Airport鈥檚 West Garage Extension not only contributes to its lasting performance, but also accentuates the intended sense of movement as the light reflects off the aluminum flapper panels that seem to dance in the wind.鈥�
鈥淰arious shapes, material thickness and finishes were tested, resulting in the curved anodized aluminum pieces that reflect light and ripple with the breeze,鈥� said David Bois, principal at Arrowstreet. 鈥淥ur partnership with EXTECH allowed us to develop and fabricate a system for the facade that would have been difficult 鈥� if not impossible 鈥� without their collaboration.鈥�
鈥淭he local glazing contractor installed the custom, prefabricated kinetic panels in record time. We believe this is a working relationship between architect and fabricator provides opportunities for innovation within our client鈥檚 budgetary and schedule constraints,鈥� said Bois.
He concluded, 鈥淭he move from the mass-produced to a more custom approach in design and construction provides for new possibilities, which parallel clients鈥� rising expectations. Without the collaborative process, this unique installation could not have occurred within the budget or the project schedule. Simple, common components come together to form an uncommon result.鈥�
