G&AI was responsible for providing comprehensive subsurface utility engineering services and land surveying for the future light rail line from Sycamore School Road to DFW International Airport. Services included static GPS for the creation of a horizontal and vertical control network for the project, supplemental topographic/design surveying and the pulling of records and mapping of utilities. This new transit program will utilize both existing and new rail. G&AI provided cost estimates for the utility adjustments at street crossings and station locations. G&AI wrote the utility summary with possible impact to the project within the EIS. Phase II included the mapping of all utilities in the existing corridors, at street crossings and proposed rail stations.
