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
