The new substations were constructed as replacements of existing substations. Test Borings were performed by SGS for each site using an AMS PowerProbe 9500 VTR to investigate the subsurface conditions. 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.
Structures included transformers, bay structures, transmission lines, substation yards, control houses, and other associated elements to the substations.
