Subsurface Utility Engineering
GdB has been providing subsurface utility engineering services (SUES) since the 1990's. We combine field locating services with our intimate knowledge of accessing and storing record plans of existing utilities (CAD/GIS), plus decades of experience designing utility infrastructure, to provide full service subsurface utility engineering services. Our service continues into the project design phase, providing utility coordination for both utility owners and municipal clients. We look at individual project needs to determine the appropriate and most cost effective Quality Level (A through D) for utility mapping.
Featured Subsurface Utility Engineering Projects
NYSDOT Subsurface Utility Engineering Services (SUES)
The GdB team has been the survey subconsultant on several statewide contracts to designate and locate utilities as needed by the NY State DOT. We work with prime consultants who perform utility research, designations, and test pit excavations. Our job is to tie into existing control as necessary, locate the test pits and paint designations, reduce the field data using InRoads Survey, and plot the utilities in Microstation according to NYSDOT standards. We then deliver the digital files and field notes to the Prime for further processing and delivery to DOT. GdB now possesses the equipment and expertise to perform the electro-magnetic induction to mark out subsurface utilities for projects similar to this one. Assignments range in size from one day jobs to weeks out on longer job sites.
SUNY Stony Brook Site Utilities Upgrade
For this project, Gayron de Bruin (GdB) was a subconsultant to Schuyler Engineering. Schuyler proposed a 13,000 linear foot route for a new high temperature hot water main on the campus of Stony Brook University. The GdB team was contracted to map the topography and existing utilities along the proposed route. To do this, we teamed with BL Companies to locate and mark out the utilities.
PSEG Long Island Underground Transmission Line - Fire Island, NY
This project is to bring two 35kV transmission lines to Fire Island. The project spans a distance of about 5 miles between the communities of Ocean Beach and The Pines. Burns & McDonnell hired GdB to perform a boundary, topographic, and utility survey of the proposed cable route.
Poseidon Transmission Cable - Long Island, NY
This is a project to bring an additional power source to Long Island. The Poseidon cable is being constructed to transmit electricity from New Jersey, via the Atlantic Ocean, making landfall at Jones Beach. The Poseidon engineers hired GdB to perform a boundary, topographic, and utility survey of the proposed 18-mile route from Jones Beach to a substation in Melville, NY.
