Switzer (Mary E.) Building

Health and Human Services Consolidation, and Modernization

Grunley has performed four projects in the Mary E. Switzer Building, a National Register of Historic Places facility. All four projects were performed while the building remained occupied and fully operational. During the first two projects, Grunley completely modernized the interior of the 592,000 SF multi-story federal building, providing modern office and administrative spaces while preserving designated historic zones. We restored the exterior stone and brick façade; replaced the existing curtainwall with thermally improved systems; and upgraded the building’s infrastructure systems. The Switzer Building is LEED Gold certified.

During our third project, Grunley fit out 300,000 SF of space to accommodate the U.S. Department of Health & Human Services consolidation. This fast-track project required selective demolition; sustainment of utilities affecting occupied spaces; and installation of interior partitions and finishes as well as building infrastructure and ADA-compliance upgrades.

Finally, Grunley constructed a conference center that accommodates 200+ users. This required major structural modifications to provide clear-span space, demolition and built-back of office spaces, meeting rooms, and public spaces; infrastructure upgrades; and complex A/V systems throughout.
