Serving as the Architect and Historic Architect for this project, Richaven worked with Cardno GS to provide a full facilities condition assessment specifically tailored to the historic Neo-Classical Revival and Mission Revival style Main Substation Building and Machine Shop.

These National Register-eligible buildings were constructed in 1923-1924 of cast-in-place reinforced concrete. The decorative features included street lamps, and cast-in-place concrete features at the windows and doors of the building as well as light monitors on the roofs of both buildings.

The assessment used a proprietary documentation system that was customized to accommodate recommendations from Richaven regarding best practice materials, repair techniques, and level of effort for each part of the building.
