 Survey Operations

Survey Operations is a division of the Department of Transportationís Office of Construction. There are five locations throughout the state that surveyors work from and where survey information is available. They are Central Surveys (Newington HQ Building), District 1 (Rocky Hill), District 2 (Norwich), District 3 (New Haven) and District 4 (Thomaston). Survey sections include boundary, geodetic, location / photogrammetry, and construction disciplines and are staffed by a cadre of Licensed Land Surveyors.

Survey Operations provide support for construction and design projects as well as providing mapping and surveying services for the Offices of Rights of Way, Maintenance, the Bureaus of Policy & Planning, Aviation & Ports and Public Transportation. The departmentís survey offices also maintain Right of Way mapping for the stateís highway boundaries, geodetic control points, state and town line data along with ancient highway and turnpike records.
