Dawood provided geotechnical hazard research and investigation services of a 60 mile pipeline in Southwestern Pennsylvania. Our team reviewed the proposed pipeline corridor for hazards like historical landslides, existence of coal mines, and depth to bedrock and slope instability.
The path of the pipeline also required geotechnical borings and geophysical surveys for two meter stations, two river crossings, two major roadway crossings and two potential landslide locations. Dawood also investigated the stability of a proposed cut and cover installation using inclinometers and presented the results to township supervisors.
The end result of Dawood’s tasks included:
- Geological subsurface profiles, with lab tested rock strength data for HDD crossings
- Foundation design for the meter stations
- Recommendations for stabilization techniques of steep slopes after construction
