Historical Information In support of this report, there are three appendices: Appendix A through C, which consist of survey photographs, historical photographs, and historical drawings, respectively.
Construction History of the Mobile Equipment Maintenance Garage: In May Clark Construction Company, of Owensboro, Kentucky, received a fixed-fee subcontract from Peter Kiewit Sons Construction Company to erect the Mobile Equipment Maintenance Garage. Groundbreaking commenced in June when Clark Construction Company began excavating trenches for the wall footers (Appendix B, Figures 4 and 5). In some areas of the site they encountered unsuitable bearing soil, which required workers to excavate below the plan footing elevation. Having excavated to a sufficient depth, workers backfilled the trench with 94 cubic yards of lean concrete to get it back to the required elevation. Structural concrete work commenced in June The footers required roughly 156 cubic yards of concrete.
Piers, grade beams, and columns consumed 53 cubic yards, and the floor slabs would ultimately require 412 cubic yards. The final pour in the slab occurred in November As work progressed on the foundation, E. R. Moyer (location not known), a subcontractor of Clark Construction Company, laid the cinderblock that would comprise the east and west walls, as well as parts of the north and south walls (Figures 6 and 7). E. R. Moyer completed its task in October having laid a total of square feet of cinderblock. Clark Construction Company purchased 78 tons of structural steel that was erected by subcontractor, Carl Vestal Steel Erector Company. Work began in August and was completed by October with all steel being riveted.
Roofing began in November and was completed by December Approximately 162 squares of roofing were installed. The steel roof deck was installed by the Carl Vestal Steel Erector Company and the built-up roofing was completed by the Tri-State Roofing Company, a subcontractor of the Clark Construction Company. Clark Construction Company completed the asbestos siding erection in December of totaling approximately 880 square feet. Mechanical and electrical installations transpired, while work on the outer and inner structure continued. Subcontractors of the Clark Construction Company installed plumbing, heating ventilation, safety lane equipment, and sprinkler system.
Contractors completed all mechanical work by March The Griffin Electric Company (location not known) began electrical work in late August The electrical work included lighting installation, panel boards, lighting circuits, power circuits, grounding, and other standard electrical items. The electrical work was completed in April (Figure 9). Carpentry was also completed in April. Due to a carpenters strike, the building s planned completion date in March was extended to April Historical drawings of building plans are provided in Appendix C (Figures 10 through Part II. Site Information Description of the Mobile Equipment Maintenance Garage: The Mobile Equipment Maintenance Garage is located slightly southeast of the center of the site, just east of the Process Building.
The Mobile Equipment Maintenance Garage provided facilities for servicing, testing, repairing, and maintenance of mobile equipment used in the operation of PORTS. The Mobile Equipment Maintenance Garage is a vernacular L-shaped utility building PORTSMOUTH GASEOUS DIFFUSION PLANT, MOBILE EQUIPMENT MAINTENANCE GARAGE HAER No. OH-142-AA (Page 3) with a relatively flat roof (Appendix A, Figures 1 through 3). Oriented from north to south, the Mobile Equipment Maintenance Garage consists of three connected service units of varying roof and ceiling heights that overall contain square feet of floor space. These include the main repair area, which comprises the central portion of the building.
It measures 61' by and has a ceiling height of A second unit is located directly to the east of the main repair area. This wing measures 24' by and has a ceiling height of The third wing is attached to the southwest corner of the main repair area. It measures 57' by 62' and has a ceiling height of Overall, the building is utilitarian in appearance, with a concrete slab floor and exposed steel framing. The building consists largely of cinderblock and steel frame construction. Much of the cinderblock construction is concentrated in the south and north walls of the building, which features large overhead doors for mobile equipment access.
These two sides of the building are almost identical to one another, with the central unit featuring a single, large overhead door in the center of the north and south walls. The west wing features three overhead doors along the width of the north and south walls. The central unit is the only unit of the three that features a slight gable in the roof. The pitch is quite low, with perhaps only ten percent slope. The ridge extends from north to south along the main axis of the building. The central wing stands approximately two stories tall but features only one floor. The wing to the west stands only about two-thirds the height of the central wing. With the exception of the overhead doors in the north and south walls, the west wing walls consist entirely of cinderblock construction.
The only windows in the west wing consist of a series of three glass panels located in each of the overhead doors. The east and west sides of the center unit, as well as the east side of the east unit, consist largely of galvanized steel sash industrial windows. A steel-framed structure and steel roof trusses support these windows, as well as the roof of the units. The large open spans within the central unit provide for an unobstructed work area through the length of the building. Truss-suspended monorails, located along the length of the east and west sides of the work area, provide a platform for travelling electric hoists. The building contains seven hoists of varying load capacities. The lower 4' of wall is comprised of cinderblock. The industrial windows rest atop this low wall.
The windows extend the length of the building. This provides for ample natural light within the center and east units of the building.
