Grunley renovated the faade and performed sitework at 1401 New York Avenue NW Washington DC. The private building owners Wereldhave USA and their subsidiaries own various commercial properties around the world. The project involved installing a waterproof membrane over the existing brick faade followed by a new framework to support the new stone cladding. The stone cladding consisted of a thin natural stone veneer reinforced with an alumi- num honeycomb epoxied to the back of the stone to improve the strength. Double 12 and triple 3thick anodized aluminum tubing was then installed over the stone veneer to provide architectural detail. Grunley replaced the glazing throughout the building with double glazing to improve the energy efficiency of the building. A new building entrance was installed with bal- anced doors and a new curtain wall system. The building streetscape was improved by the installation of granite slate and concrete pavers along with planting of new trees. All work was performed while the building remained fully occupied and operational including all retail establishments. 1401 NEW YORK AVENUE NW FAADE RESTORATION Washington DC OWNER Wereldhave USA DATE OF AWARD January 2007 COMPLETION DATE August 2008 CONTRACT AMOUNT 9M ARCHITECT ManciniDuffy Winstanley PROJECT AWARDS American Institute of Architects Potomac Valley Chapter Citation 1401 New York Avenue Faade Renovation 2008 Before
