    Please join APT DC and Grunley Construction Company for a tour of the exterior restoration of the Sidney Yates Building! 

    The Building

    Built between 1878-1880, the Sidney Yates Building is a grand example of Richardsonian Romanesque design – a common aesthetic for the late 19th century, but uncommon for its location and Federal use.

    Named after the Honorable Sidney R. Yates, a member of the House Appropriations Committee for the Department of the Interior and other agencies for many years, the clock tower and original structure began construction in 1878. Completed in 1881, the building was originally used by the Bureau of Engraving and Printing.

    The building has undergone several expansions, renovations, and restorations in its lifetime, and it currently houses the United States Forestry Service.

    The Restoration

    The scope of work of the most recent exterior restoration included re-pointing and masonry repairs, casting replicated brick units, installing metal flashing on masonry bands, window conservation with localized repairs and metal capping of transom bars, and perimeter gutter replacement. Representatives from Grunley will lead the tour and discuss the various restoration techniques and materials used.

    Please join APT DC as we spend an evening recognizing and learning from some of our members’ incredible work preserving our national monuments. The event will include two short lectures followed by a joint question and answer session, and our distinguished speakers are:

    Audrey Tepper, an Historic Architect with the National Park Service at the National Mall and Memorial Parks, who will speak about several of the current projects at the Mall as well as the challenges associated with maintaining and preserving well-known monuments and memorials.

    Tim Vandewalle, Superintendent at the Christman Company, who will discuss the restoration of the U.S. Capitol dome using the "Lock-N-Stitch" technique for the historic cast iron repairs, including the strengths, limitations, and preservation options provided by this repair methodology. 

    Beverages and snacks will be provided. We hope you'll join us for this special event!
