FM 2004 Subsurface Utility Engineering and Utility Coordination – Texas Department of Transportation

Galveston County Texas

LAN is currently performing subsurface utility engineering (SUE) and utility coordination services for pedestrian and traffic signal improvements on FM 2004 between Jack Brooks Dr. and Oak Rd. Because of the complex retaining wall foundations needed to support the subgrade beneath the sidewalks while maintaining an open ditch system, utility investigations were paramount to ensure no impacts to the existing utility locations.

LAN’s team mapped the existing utilities and analyzed that against the consultant’s design to uncover conflicts. It was the client’s desire to avoid all conflicts with utilities which posed a great challenge as there were several gas pipelines running parallel and crossing the roadway along with the City of Hitchcock’s sanitary sewer system running in tight proximity to the proposed sidewalk. Maintaining clear distance from these utilities while allowing for proper ditch gradings meant that LAN had to work closely with the roadway consultant to modify the design in key locations to make this project a success. Utility conflicts were not just a desire to TxDOT, but also to the City of Hitchcock as their budget could not handle the magnitude of relocations needed with the original design. LAN displayed not only strong communication skills, but also technical prowess to avoid every conflict. The engineers and technical leads involved expressed the gratitude of the mayor for LAN and TxDOT’s teamwork on this project.
