CMP SUBSTATIONS
- Project Location: Bristol, ME; China, ME; Sanford, ME
- Services Provided:
- Geotechnical consulting.
- Test borings were performed for each site using an AMS PowerProbe© 9500 VTR to investigate subsurface conditions.
- Project Summary:
- The new substations were constructed as replacements of existing substations.
- Structures included transformers, bay structures, transmission lines, substation yards, control houses, and other associated elements to the substations.
- Project Challenges / Innovation:
- Subsurface conditions ranged from fill, alluvial sands, glacial till, and shallow bedrock.
- Resistivity testing was conducted for each site using Wenner 4 Probe method.
- Geotechnical design included a range of challenges from earthwork cut/fills, global slope stability, changes in subgrade conditions, various foundation systems (footings/piers/piles), frost design, seismic design, and corrosion potential.
