Replace Diesel Fuel System Components

1. Introduction:

The National Park Service, Interior Region 2, South Contracting Office, Homestead, Florida, 33034, seeks responsive bids for inspections, repairs, alterations, and replacement of various components to a diesel fuel system including underground storage tanks, controls, wiring and conduits, distribution, and safety equipment noted here and in the Specification.

2. Background

The diesel fuel system is located on an offshore island of Dry Tortugas National Park, approximately 68 miles W of Key West, Florida, 33040. Job site is in the sub-tropics of the southeastern Gulf of Mexico, reached by seaplane or vessel only. Weather is hot and humid year-round. Terrain is flat, 3 feet above sea level, and mostly sand with southern turf grasses and unimproved pathways.
