Electric distribution lines in the downtown alleys of Redwood Falls, MN consisted of large overhead structures which included transformers mounted on platforms. Due to concerns with the age and condition of the structures, along with safety clearances to energized equipment and conductors, a project was undertaken to replace the old infrastructure with new underground lines and associated padmount equipment. In addition, these improvements would improve the overall attractiveness of the area.
The 11 block project was split into two phases to allow for completion over two construction seasons. In addition to burying the overhead primary circuitry, most of the overhead secondary circuitry associated with the conversion area was converted to underground.
DGR Engineering developed a full design for the new underground circuitry, including equipment and cable sizing, equipment locations, line routes, and material lists. Bidding and contract documents for construction of the improvements were developed, which included detailed design drawings, staking sheets, and technical specifications. The completed project resulted in a safer and more aesthetically pleasing downtown area that was also up to current standards for infrastructure and reliability.
