00The Río Piedras Contract consists
of a 1,500-meter long underground rapid transit guideway with two underground
subway stations. The project is partially funded by the U.S. Federal Government
as a demonstration DB project. The alignment traverses a dense urban area
and geotechnical conditions consist of weathered alluvium (soft ground).
Most of the project structures are located below the groundwater table
and many of the tunnels pass beneath occupied historical buildings with
less than 5 meters of cover.
