Triad Engineering, Inc. provided Professional Survey Services for the design and engineering associated with the Berkeley Springs Bypass in Morgan County, West Virginia. The project involved providing design surveys for a proposed new highway (U.S. Route 522) near Berkeley Springs, West Virginia.
There were three proposed project limit corridors to be assessed. The primary corridor consisted of 109 acres, the first alternative corridor contained 20 acres and the 2nd alternative corridor contained 25 acres.
Triad’s survey team was tasked with performing the following services for each of the three project limit corridors:
- Triad was tasked with establishing GPS control points within each of the project limit corridors.
- We completed property line surveys and acquired ownership data on impacted properties within the proposed corridor. From this data, we prepared and processed right-of-way questionnaires.
- In addition, we conducted research to obtain flood elevations and historical flood data potentially impacting the area within the project limits.
- Triad completed LiDAR aerial topographic mapping and supplemental field run topographic mapping and structure data surveys to identify non-LiDAR observable objects such as valves, meters, hand holes, etc.
- Triad extracted 3-dimensional data from the LiDAR DTM mapping along the existing paved surfaces where new construction will tie into the existing roadways. Spot elevations were generated on the edges of pavement, paved shoulders, lane lines and centerlines, crossing the full width of the roadway on a ten-foot interval.
Triad executed a series of field run bathymetric stream cross sections for 300 linear feet on either side of a proposed bridge crossing at Warm Spring Run. There was a total of 7 cross sections. This task was only associated with the primary corridor project limits.
