About this file
This is a site investigation report documenting the electrical infrastructure assessment at Manhole 8 Transformer located at Kentucky Lock, conducted by United States Army Corps of Engineers (USACE) Louisville District (LRN) Personnel on June 22, 2026. The investigation examined power conduits, transformers, and disconnect switches serving the lock's electrical systems. Critical findings include the identification of corroded high and low side disconnects on the transformer requiring replacement with new in-kind units, de-energized conduits serving light and gate power systems, and protruding cables from the top of the Manhole 8 duct bank. The report documents two downstream circuits—one serving high mass lighting and another believed to serve a tow haulage unit—both found de-energized during the investigation, along with chipped and patched areas along the power run route.
The report identifies a concrete pad and adjacent wall area as a suitable relocation site for the transformer and disconnect switches, selected to facilitate improved maintenance access and future testing procedures. Supporting documentation includes seven figures and corresponding photographs (image1.jpeg through image7.jpeg) illustrating the conduit routing, existing corroded disconnects, the duct bank configuration, and the proposed relocation area. This site investigation directly supports the Department of the Army Corps of Engineers, Nashville District's firm fixed price commercial construction contract solicitation (W912P526QA050) for transformer relocation at Kentucky Lock, 265 Kentucky Lock Road, Grand Rivers, Kentucky 42045, which requires contractor provision of all materials, labor, supervision, and quality control for project completion.

This report summarizes the findings from the Manhole 8 Transformer site investigation at Kentucky Lock on 06/22/2026 by USACE LRN Personnel.
The investigation focused on the electrical infrastructure around Manhole 8, including power conduits, transformers, and disconnects. A key finding is the recommendation to replace the old and corroded high and low side disconnects for the transformer. The power run from Manhole 8 to the light and gate power was observed to have been de-energized.
Several conduits and circuits were identified. One conduit for light and gate power was confirmed to be de-energized during the investigation. Another downstream conduit contains two circuits: one for the high mass lights and another believed to be for a tow haulage unit, which was also not energized. Additionally, cables were seen protruding from the top of the Manhole 8 duct bank. For future improvements, a concrete pad and wall area was identified as a potential relocation site for the transformer and disconnects to allow for easier maintenance and testing.
