Feasibility of Utility Corridors at Fort Lincoln
This study was concerned with the possible inclusion of utility corridors at Fort Lincoln, a new town development in Washington, D.C. Five utility corridor concepts were developed to determine the technical, economic, and legal advantages and disadvantages each would have if adapted to the specific location. Under consideration were the following corridor concepts: common trench, utility - in - pavement structure, pour - in - place concrete tunnel, precast concrete tunnel, and prefabricated corrugated steel tunnel. In general, all of these concepts involve the aggregation of utility lines into close proximity to one another, and their convergence raises problems of security, compatibility between lines, access, liability, and system simplicity. The technical and engineering problems related to the construction and operation of a utility corridor can be solved or reduced to a minimum, but only at a sacrifice of added costs and greater system complexity. The study found the common trench and utility - in - pavement designs at Fort Lincoln to be comparable in cost to conventional installations, while the tunnel constructions were estimated to be two to three times as expensive. In general, it is concluded that utility corridors appear to be technically, financially, and legally feasible at Fort Lincoln, although time limitations caused by pressing schedule requirements in site development are a problem. This conclusion was based on an analysis of the general site characteristics of Fort Lincoln, its utility requirements and existing installations, the feasibility of each corridor concept, a cost - benefit analysis in terms of capital and maintenance costs, and the legal framework. Legal considerations involved reference to specific laws affecting matters of installation and operation, methods of securing easements and other rights, and the determination of liability for damages arising out of the construction and maintenance of utility tunnels. Seven tables, numerous figures, and footnotes are supplied. (Author abstract modified).
