REPLACE PLUMBING AND FIRE PROTECTION SYSTEMS (B150), TIN CITY, ALASKA (TIN006). Design and repair of the plumbing and fire protection systems within composite building B150, Tin City Long Range Radar Site (LRRS), Tin City, Alaska. The Tin City LRRS is located near the western tip of the Seward Peninsula approximately 650 air miles northwest of Anchorage, AK, a logistically challenging, remote location accessible only by air and/or barge. Building B150 is 4 stories, with the third story unoccupied. The facility was originally designed for over 300 personnel to operate this remote radar site, however, is minimally manned for maintenance of the facilities. The building occupancy and use will not change. Design and repairs include replacement of the existing fire sprinkler system, plumbing systems, and will incorporate all related architectural, structural, electrical, and other necessary supporting disciplines to complete the design and repair. The repair will need to accommodate for minimal impacts to existing operations within the facility, including the establishment of a complete temporary kitchen to support meal preparation and cleanup when the permanent kitchen is shut down for plumbing repairs.
