I35W North Tarrant Express Segment 3A
CobbFendley was responsible for subsurface utility project management for this project, providing both utility designation (Quality Level B) and vacuum excavation test holes (Quality Level A). CobbFendley has performed over 500 test holes throughout the project. At each test hole location, the target utility was designated and surveyed for 500 feet in each direction, per the client’s request. This additional information proved to be extremely valuable as the alignment frequently had to be shifted to avoid or lessen utility conflicts. More than 100,000 feet of buried utilities have been designated. The client was provided with a MicroStation file of the test hole data sheets and the utility designation.
