PES provided the structural design for renovations to the historic Flatiron Building at 84 Peachtree Street.
The existing 40,000 square foot, 11-story slender, wedge-shaped building utilized iron framing with masonry walls and elevated floors consisting of clay tile spanning between beams with a 6’ sand bed on top. This type of structure was only used on a handful of buildings in the late 1800s and early 1900s and was certainly unique to work with.
The scope of work included a preliminary condition survey prior to demolition to provide feedback on what was required for the structure; providing a final condition survey after the demolition was complete for the existing structure; providing reinforcing details for the existing structure in order to restore the structural integrity of any members that were affected by the wear and tear of the existing building; and provided observation of the installation of any reinforcing added during construction.
Now called FlatironCity, the structure houses technology tenants such as the nation’s second Microsoft Innovation Center, the Women’s Entrepreneur Initiative, Launch, and Aegex.
