U.S. STEEL DUQUESNE WORKS HAER No. PA-115 (Page 213) 1/4" long x 25'-5 3/4" lean-to is located on the south wall of the building. Brick walls encase the structure's steel framework- Fink trusses support the roll shop's wood and tar paper gable roof. A craneway spanning the width of the roll shop and running its entire length supports one 15/5-ton E.O.T. crane. Segmented arch windows rim all four walls of the roll shop and lean-to on both stories. Two large entrances are located on the northern and western walls of the roll shop (an approximately lO'-O" wide x lS'-O" high entrance on the north wall at its western end and an approximately 10'-0" wide x 20'-0" high entrance on the western wall at its southern end). Access is gained into the lean-to from the southern end of the roll shop. Located outside of the roll shop's western wall, near the entrance, are six scrap bins. A turret lathe is located inside of the roll shop along its western wall near the entrance. The rest of the roll shop consists of a storage area for spare fan housings, flywheels, transformers, and motors. The lean-to houses a tool room, washroom facilities, and offices. Construction date: 1906. II. Primary Rolling Facilities at Lower Works: A. D.P.C. Conditioning Yard Building: Constructed by the American Bridge Company, the steel-framed building is 500' long x 85' wide x 42' high to the underside of the truss. It is located 33* east of the electric furnace building and is laid out on a north-south axis. Its northern end (approximately 40 f ) runs parallel to the southern end of the electric furnace building. The building's gable roof and continuous ventilator is supported by riveted Pratt trusses. It has a corrugated metal exterior. A craneway spans the width and runs the length of the building. It supports two 2 5-ton E.O.T. cranes. A standard gauge railroad track runs through the building on its eastern and western side. An electric powered mobile Mid-Western Grinder runs on rails along the eastern and western inside wall of the building at its northern end. A 300 f long x 17 f wide x 12* high steel-framed hot topping ingot mould platform runs along the inside eastern wall of the building at its southern end. Two 25 f long x 15' wide x 12• high corrugated metal lean-tos are built onto the outside eastern wall of the building near its northern end. Each lean-to houses a large motor and fan which draws fumes from inside of the conditioning yard building into a ventilation hood protruding through its roof. Construction date: 1943. Construction of 75' extension to its southern end: 1957.
U.S. STEEL DUQUESNE WORKS HAER No. PA-115 (Page 214) B. D.P.C. Steel Conditioning Office and Storage Building: Laid out on a north-south axis, and built onto the eastern outside wall of the D.P.C. conditioning yard building at its southern end is a 220■ long x 18' wide x 12' high brick lean-to. The building houses the steel conditioning office, the grinder storage room, the tool storage room, a locker room, and a wash room. Construction date: 1943. C. Primary Mill Building: Laid out on a north-south axis, the primary mill building is located in the lower works near the shore line of the Monongahela River. The corrugated metal clad, steel framed building was built on a concrete foundation by the American Bridge Company. It is 90'-0" wide x 2412'-0" long x approximately 70'-0" high to the underside of the truss. Its gable roof and monitor is supported by riveted modified Fink trusses. A craneway, supporting several E.O.T. cranes, spans the width and runs the entire length of the building. The building can be divided into three contiguous sections (i.e. the ingot stripper section, the soaking pit section, and the mill section itself). The building also accommodates a scale and waste water collection system. 1. Rolling Facilities: a. Ingot Stripper Section: The ingot stripper section occupies the southern end of the building. It is 244 , -0" long. The interior of the section is served by five narrow gauge tracks and one standard gauge track. The tracks enter and exit the building through its open southern end. The stripping facilities consist of two Alliance E.O.T. stripping cranes (one 50/25-ton and one 50-ton crane), each with a stripping force of 400 tons. A 1000-ton Lowey Hydropress ground stripper is located at the northern end of the stripping area on the western side of the building. The ground stripper was used to strip ingots which had become "stuck" to their moulds. Located on the eastern side of the ingot stripper area are two narrow gauge robotic locomotives (numbers 6 and 9) and five standard gauge diesel locomotives (numbers 26, 117, 157, 461, and 810). Number 26 is labeled "Homestead Works". Seven ingot cars, each carrying an ingot mould, are also located inside of the ingot stripping section. b. .Soaking Pit Section: The soaking pit section is located just north of the ingot stripper area. It is 448'-0" long. Eight banks of soaking pit furnaces (each containing four furnaces), laid out in a single line on a north-south axis, are located near the western wall of the building.
