Trinity River Authority of Texas (TRA), Bear Creek Interceptor, Dallas, Texas

CRIADO provided project oversight for manhole and pipeline inspection work. The project scope included approximately 10,200 linear feet of 54-inch and 84-inch sewer line (per NASSCO PACP®). CRIADO provided top-side manhole inspections for 8 manholes. Record research for easements and subject properties were also provided. CRIADO converted all horizontal data to surface distances using the surface adjustment combined scale factor for design engineering. GPS data was collected and evaluations were adjusted to meet TRA’s benchmarks.
