Public Space Renewal, Roof Repair and Garage Infill Conversion

Grunley performed three projects at the NMAH, all while the museum remained open and operational. First, during the PSRP III project, we renovated the 127,000 SF NMAH west wing exhibition space. The project space features new exhibition galleries, an education center/learning lab, a new music hall, and a demonstration kitchen. The project is LEED CI 2009 Silver certified.

In a separate project, Grunley converted 30,000 SF of garage into a suite of offices and a daycare center. This required structural strengthening, extensive waterproofing, two new glass entrance pavilions and high-end finishes.

Finally, Grunley also completed a roof and terrace repair project totaling 120,000 SF including stonework, exterior lighting and power, and new fire alarm devices. During all three projects, Grunley upgraded mechanical, electrical, plumbing, lighting, fire/life safety, communications and security systems.
