The American Bar Association Headquarters was originally built as the Union Trust Building in 1907, and designed by the well-known Washington, D.C. architectural firm, Wood, Donn & Deming. This post-classical granite building features ornately detailed windows with pressed metal and iron grillwork. The Union Trust Building is listed on the National Register of Historic Places.
WEI completed exterior masonry repairs in 2007. This included cleaning all granite and limestone; replacing existing iron pins and cramps with stainless steel at the 10th floor granite baluster; patching the granite elements with matching tinted mortar; injecting epoxy in stone cracks; cutting out and re-pointing damaged mortar joints; patching exposed aggregate precast concrete; and removing the existing post-and-wire bird deterrent system.
Since the configuration of the building required the scaffolding to be set back from the façade, additional interior platforms were anchored to the main structure to bridge the gap. All walkways had overhead protection, and scaffolding was wrapped in netting to protect pedestrians and vehicular traffic from debris.
WEI had to provide access to the building during business hours, even while working on the doors to these entrances. Work was staggered to allow partial access through each main opening. Security was a priority throughout the project. Many tenants occupy the building, and construction crews were escorted while they worked inside. Replacing windows for the corner bank also required special security measures.
Non-masonry work included restoring the double-hung wood-sash windows; recaulking around all windows and building expansion joints; stripping, repairing, priming, and painting decorative pressed metal between the fourth and eighth floors; stripping, repairing, and painting ornamental cast iron light stands; providing scaffolding to access the entire façade; and stripping, priming, and recoating the monumental iron bars, windows, and doors on the ground floor.
