The New York State Capitol was constructed between 1867 and 1899 under a series of supervising architects starting with Thomas Fuller, followed by Leopold Eidlitz and Henry Hobson Richardson, and lastly Isaac G. Perry. It was listed on the National Register of Historic Places in 1971 and designated a National Historic Landmark in 1979.

BCA has been involved in many restoration projects at the capitol, including a cleaning program for the interior monumental sandstone staircases; assessment and construction administration for the restoration of the Capitol’s interior courtyard; and peer review design documents for the comprehensive repair and rehabilitation of the Eastern Approach Staircase, North and South Promenades, the Eastern Portico, and the Executive Ramp.
