Corporation, Duquesne Works, Auxiliary Buildings and Shops Location: Duquesne Works Construction: varied Documentation: Photographs of the Auxiliary Buildings and Shops located in HAER No. PA-115-F. DESCRIPTIONS AND HISTORIES I. Locomotive Repair Shop: Laid out on a north-south axis, the two story, 119'-6" long x 72'-l" wide Locomotive Repair Shop is located 40' east of the 21-inch Mill Inspection Building at the northern end of the upper works. Constructed on a concrete foundation with a concrete floor by the American Bridge Company, the steel-framed building is covered with corrugated metal. Its gable roof and monitor is supported by combination wooden Pratt trusses and steel tie rods. Located inside of the building are four repair pits, each approximately 100' long x 4 1 wide x 7' deep, which run parallel to each other. They were used to provide repair access to the underside of company owned locomotives. Access to the two repair pits on the eastern side of the building is provided by a pair of standard gage railroad tracks which run through an opening in the northern wall of the building. Access to the repair pits on the western side of the building is provided by a pair of standard gage railroad tracks which run through an opening in the southern wall of the building. The building also contains a tool room and a small office, both of which are located in its northwest corner. Located along the building's eastern wall is a turret lathe and a U.S. Electrical Co. grinder. A smaller turret lathe is located along the western wall of the building and a Hammond Machinery grinder is located along the northern wall. Construction date: ca. 1900. II. Boiler Shop: Located just east of the Locomotive Repair Shop, the two story, 114' long x 70' wide Boiler Shop is laid out on a north-south axis. The steel-framed, corrugated metal building was constructed on a concrete foundation by the American Bridge Company. Its gable roof and monitor are supported by Pratt trusses. A 5-ton E.O.T. crane runs the length of the building. Once utilized for the fabrication of steel plate forms, the inside of the Boiler Shop was completely gutted at the time of the HAER inventory. Construction date: ca. 1910.
A U.S. STEEL DUQUESNE WORKS W HAER No. PA-115 (Page 250) III. Machine Shop: Laid out on a north-south axis just east of the Boiler Shop, the two story, 220' long x 122' wide Machine Shop is the oldest structure on the Duquesne Works site. Constructed on a concrete foundation by the Keystone Bridge Company, the steel-framed building has a brick exterior and a concrete floor. Its gable roof and monitor are supported by Pratt trusses. Segmented arched windows run along the upper part of the building's eastern and western walls. The inside of the building is divided into three bays which run its length. The eastern bay of the building contains tool storage bins that sandwich a small office at the center of the bay. The building's center bay is serviced by 30/10-ton E.O.T. crane. Once used to machine parts for much of the mill's production equipment, the Machine Shop was, at the time of the HAER inventory, completely gutted of all machinery. Built off of the northern wall of the Machine Shop are two small, one story tall, brick lean-tos. One lean-to was used as an office while the other was used as a locker room. Construction date: 1887. Q IV. Pattern Storage Building: The six story, 116' long x 56' wide Pattern Storage Building is laid out on a north-south axis approximately 100' west of the 21-Inch Mill Inspection Building at the northern end of the upper works. Constructed by the American Bridge Company on a concrete foundation, the building's brick exterior encases its steel framework. Dormer windows rim the third floor of the building, while segmented arched windows exist on each of its other five floors only on its eastern wall. The building's corrugated metal gable roof is supported by Fink trusses. A covered stairway leading to the second floor of the building is located at its northern outside wall. Attached to the southern outside wall of the building is an elevator which was used to transport large patterns to and from its storage floors. The layout of the building's sixth floor consists of a single bay in which large patterns are stored. The layout of the fifth and fourth floors includes two rows of large tiled columns which divide the floors into four equal bays. Both floors are used for the storage of patterns. The third floor of the building consists of a center aisle which is flanked by a series of wood panelled maintenance division offices. The arrangement of the third floor is the result of a reconstruction which took place in the early 1970s. The northern end of the second floor of the building was utilized for the storage of gas rescue equipment. Just south of this storage space is a center aisle 4fe flanked by a oxygen bottle repair office on its eastern side and ^^ a locker room on the western side. The southern end of the floor
