A New York City Landmark, the Consolidated Edison Company Building is an iconic example of Renaissance Revival architecture (Henry J. Hardenbergh, 1911, with later additions by Hardenbergh and Warren & Wetmore). SUPERSTRUCTURES’ team provided investigation, design, and construction administration services to restore the building’s limestone, granite, brick masonry, stucco, copper, and bronze facade. Investigation methods included a Gigapan survey of the building’s envelope and examination of the cupola via rope access. Restoration work included: sounding and removal of limestone spalls; replacement and patching of cracked limestone masonry using micro-injection grout; dutchman stone repairs; brick and stone masonry repointing; sealant installation; and stucco coating repairs.
