Project Description
DeBruin provided surveying services for both the Marble Hill and the Port Chester lines of the Metro-North Railroad. For the Marble Hill location local control was established on site. For vertical datum, we used control points provided by Metro North so that our work was readily comparable to historical data. Work also included railroad ROW, and mapping was completed that was suitable for use in preparing a builder’s pavement plan. For the Port Chester Line local control was established on site. For vertical datum, we used control points provided by Metro North, so that our work was readily comparable to historical data. Topo survey was done from instrument stations on the railroad embankment. Both sides of the railroad were surveyed. Property lines were established and included location of easements that were found on or adjacent to the property. Utilities were located which included overhead wire heights.
