Article VII Survey – PSEG LI

Valley Stream to East Garden City

GdB was hired by Burns & McDonnell as a WBE Certified Subconsultant to provide various Land Surveying services on a proposed route for a new 138KV Underground Transmission cable to be used by PSEG to deliver reliable service and grid resiliency to Southwest Nassau County after the failure of two existing 50+ year old cables. To begin the survey of the lengthy 7.5 mile long corridor, GdB employed the use of a local Aerial Photogrammetrist to procure a new flight and photogrammetric mapping. Supported by high accuracy ground control, the photogrammetry provided high resolution digital Orthophotos and Topographic mapping with 1’ contours for the entire length of the project. Once the mapping was processed and completed, GdB used traditional ground survey to verify the data gathered by the aerial mapping and locate any and all missing features in the field.

Term Agreement for Surveying (TASS)

Long Island and New York City

The team at GdB has been working on TASS contracts since 1996. So far, we have been awarded 8 of these open services contracts consisting of several survey and mapping assignments, some of which are listed below. We have done high accuracy control surveys, topographic base mapping, utility mapping, hydrographic surveys, right of way and property line surveying, acquisition mapping, and stakeout work. All mapping was done according to NYSDOT mapping and CAD standards.

Mayoral Vision Zero Great Streets Program

Queens Boulevard

As part of a New York City initiative to eliminate all preventable accidents on city roads, GdB teamed with Nelson and Pope (N&P) to provide topographic mapping for over six miles of Queens Boulevard to be used for designing safety improvements by the NYC Department of Transportation. To complete the mapping along a busy, multi‐lane highway, GdB and N&P employed mobile LiDAR to collect the field data. The data was then used to create existing conditions plans according to NYC Department of Design and Construction CAD standards which includes clean base plans, topographical plans, highway profiles and utility plan and profiles. The project was divided into 4 phases and GdB/N&P worked to complete each phase on an accelerated schedule, on time and within budget.

Fire Island Stabilization Project, Fire Island Inlet to Moriches Inlet (FIMI) – Property Surveys

Fire Island, NY

GdB provided boundary surveys and legal descriptions for more than 70 parcels on Fire Island to assist the County and the Army Corps of Engineers in a dune replenishment project to protect the island from future storm erosion. GdB was one of several consultants chosen to survey parcels along the south shore of the island. In addition to surveying the parcels assigned, GdB coordinated with the other consultants to produce a GIS and overall mapping for the County to use for planning and presentations to interested civil associations. GdB also performed 3D Laser scanning and modeling to show the Army Corps profiles and cross sections of the proposed dunes as they relate to existing homes and decks.
