Historical Information In support of this report, there are three appendices that are provided: Appendix A through C, which consist of survey photographs, historical photographs, and historical drawings, respectively.
Construction History of the Guard Headquarters: Peter Kiewit Sons Construction Company subcontracted the construction of the Guard Headquarters to the Clark Construction Company, of Owensboro, Kentucky (Appendix B, Figures 4 through Construction on the Guard Headquarters began in the summer of and was largely completed by August The building was renovated in and the northwest addition was built in Historical drawings of building plans are included in Appendix C (Figures 13 through Part II. Site Information Description of the Guard Headquarters: The Guard Headquarters is a vernacular, one-story, rectangular shaped building located just inside the main entrance to the limited area of the site. The building shows elements of the International Style (Appendix A, Figures 1 through 3).
The building served as the central operation point for protection forces assigned to PORTS. It consists of three independent structures joined by a connecting corridor. The main structure, located in the center and eastern portion of the facility, houses the offices, supply rooms, restrooms, and locker facilities. The smaller building on the southwest corner houses the guard communication facilities. The slightly larger addition on the northwest corner contains training rooms, offices, and storage areas. Also associated with the Guard Headquarters is a steel-frame, two-bay garage, and the X-104A Indoor Firing Range, adjacent to the north.
The main structure is approximately 96' long and 76' wide (approximately square feet), with a small, southern wing protruding approximately 14' beyond the south fa ade. The Guard Headquarters has a very low-pitched gabled roof with the ridge extending from north to south. The building has a concrete slab foundation and concrete block bearing walls. Window openings on the main building contain commercial-type, projected steel sash with double-strength B-grade glass and cast concrete sills. A simple wood trim fascia runs the width of the roofline. Exterior doors are wood with metal canopies above, with the exception of the metal security door to the communication building. The main double entry doors on the south fa ade feature large glass panes with metal door pulls.
The roofline is punctuated by a variety of metal vents, exhaust fans, and air intakes. An incinerator was originally located on the north fa ade and was used to burn classified and business sensitive documents. The interior of the main building originally featured a central corridor on the western half of the building with a large open locker room to the east and smaller rooms for offices and other uses on the west, as well as a smaller connecting corridor to the communications building. Interior partitions and ceilings are composed primarily of wood studs and gypsum board. Partition walls in the toilet and shower rooms consist of glazed tile walls and plastered ceilings, while the partition walls in the ammunition room are reinforced concrete.
The finished flooring throughout the building is composed of the polished concrete slab, with the exception of ceramic tile in the restrooms and asphalt tile in the offices. Ceilings throughout the building are approximately 9', 5'' high. The building was renovated in and the layout was altered to its present configuration. PORTSMOUTH GASEOUS DIFFUSION PLANT, GUARD HEADQUARTERS HAER No. OH-142-J (Page 3) The communications building is approximately 44' long and wide with 9' ceilings and features reinforced concrete construction and a flat roof. The concrete walls have no window openings, and there is one exterior steel door on the west fa ade.
The original connecting corridor is also of reinforced concrete construction and contained steel doors at either end of the corridor for security purposes. Renovations in extended the west wall to the edge of the main building, encompassing the connecting corridor. The interior features a partition wall separating the main communications room on the south from the emergency generator and restrooms on the north. The concrete slab floor features a large cable trench in the communications room that was covered with vinyl asbestos tile during the renovations. The addition on the northern half of the west fa ade was built in for additional training space.
The addition matches the construction materials and design of the main building with a concrete slab foundation and concrete block bearing walls. Also associated with the Guard Headquarters is the X-104A Indoor Firing Range to the north of the main building. The building serves as a practice firing range for PORTS protective forces. The X-104A Indoor Firing Range was built in conjunction with the northwest addition to the main building in The building is approximately long from east to west and 27' wide from north to south. There is a screen wall to the north of the building hiding the mechanical space. The building features a concrete slab foundation, concrete block bearing walls, no windows, and metal doors with aluminum canopies.
