Campus building

This project included a topographic survey and utility inventory of 7.5 acres of the SUNY Farmingdale campus. B Thayer Associates created a horizontal control network throughout the campus using GPS and conventional total station traversing techniques. Two sets of inter-visible coordinate pairs were established via GPS observations. A conventional closed traverse that encompassed all four points was completed and the horizontal positions were adjusted to the New York State Plane Coordinate System. On-site elevations were generated by differential leveling from benchmarks previously established on campus. Detailed topographic mapping of the work area was then undertaken. All major improvements were located along with enough topographic data to generate contours on a one foot interval. Utility mark-outs were located and a detailed utility inventory was performed. All sanitary and drainage structures were accessed by B. Thayer Associates survey staff. Invert elevations, pipe diameter and type, direction of flow and general condition of the structure were observed and recorded. Multiple generations of record plans from various sources were reconciled with data collected in the field to determine the location of various utility lines (both functional and abandoned).
