New York City Topographic and Utility Surveys
Since 2001 Bowne has had a Requirements Contract with New York City Department of Design and Construction to perform extensive topographic and utility surveys in various locations in Staten Island, Manhattan, Queens and the Bronx.
Catch Basin Surveys
Of particular interest are the 65 sites in Manhattan. Many of these sites were over the New York City subway system. Each subway line had to be researched and the underground features of the various lines had to be accurately drafted onto the final drawings. Sites impacted by Long Island Rail Road and Amtrak tunnels had to be researched by obtaining information from Amtrak archives.
Hunters Point Survey
R&T Building Rehabilitation and Survey
This survey was a continuation of a prior survey for the Department of Design and Construction which was a topographic survey along Hunters Point Avenue. It included the location of the roof communications tower with a determination of its height (hundreds of feet) and ancillary antennae. Bowne also surveyed the remainder of the R&T building and the surrounding area, and all data was presented as composite mapping.
Bowne services included a topography survey, the preparation of maps by AutoCAD and data assembly, verification/revision of maps and assembling utilities.
Sewer and Water Main Projects
Both projects were completed to exacting mapping standards of the Department of Design and Construction and conformed to requirements of the Department of Environmental Protection.
Bowne produced topographical and utility maps as well as profile drawings for both projects. The project in Manhattan was done in an extremely heavy vehicle and pedestrian traffic area, limiting available field time.
