They also represent the daylight factory design type, with exposed structural skeletons, large window bays and open floors. The Micanite Works is a reinforced concrete example, and the later Lamicoid Building is a steel-framed example modeled on it.","narrative":"Two factory buildings on Broadway in Schenectady are all that remain of a large manufacturing complex built by the Mica Insulator Company. The four-story Micanite Works, built in 1915 and later enlarged, has a reinforced concrete skeleton, big bays of steel industrial windows and open floors. The three-story Lamicoid Building followed in 1946, housing offices and manufacturing of a new product line. It uses a steel frame with brick walls but closely echoes its older neighbor. A walkway once linked them. The company was founded in 1893 by former Edison Machine Works and GE researchers and was long called Schenectady's third largest industry, after GE and ALCO. The Micanite Works was designed by William Lee Stoddart and built by Turner Construction. The buildings were listed for their link to this company and as examples of daylight factory design. The Micanite Works is vacant and damaged but retains much of its integrity, while the Lamicoid Building has been rehabilitated for offices.","period_of_significance":"1915 - 1946","architect_builder":"William Lee Stoddard (Stoddart); Turner Construction Company","architectural_style":"Other: daylight factory","criteria":["A","C"],"status_note":"The Micanite Works is vacant and in fair condition, with broken windows, roof leaks and interior damage.
