SUBSURFACE UTILITY ENGINEERING

Subsurface Utility Engineering (SUE) is a crucial field that involves the identification, designation, location, and mapping of existing underground utilities and voids using advanced technologies such as Ground Penetrating Radar (GPR) and pipe and cable locators. These services provide detailed information about the position and condition of subterranean infrastructure, including water and gas pipelines, electrical and communication cables, and sewer lines.

By accurately mapping these utilities, SUE helps prevent accidental damages during construction and excavation projects, thereby reducing the risk of costly repairs, project delays, and safety hazards. This is especially beneficial for businesses in sectors such as construction, civil engineering, urban planning, and infrastructure development, where understanding the subsurface environment is essential for successful project execution.

Nashville District Structural Deformation Surveys - Cordell Hull & Center Hill Dams

SEAS, in collaboration with the USACE Nashville District, executed precise dam deformation surveys for the Center Hill and Cordell Hull Lock and Dam project sites. Leveraging TerraSurv's expertise in Dam Deformations & Geodetic surveying, the comprehensive survey involved equipment calibration, recovery and survey of control monuments, geodetic-quality vertical leveling, and alignment pin surveys using 1” total stations. The survey report, aligned with EM 1110-2-1009 guidelines, encompassed accuracy statements, equipment calibrations, QC processes, and a thorough summary, ensuring compliance with the highest standards.
