See Appendix A for informational photographs of current conditions.

An electrical panel is located in proximity to existing furnace. A four-plug outlet is currently located nearby (See Existing Conditions photographs in Appendix A).

Circuits for the existing boiler and single bay garage heater may be used for new equipment. Two electrical outlets also exist in proximity to the location for the new furnace and water heater and may be repurposed as needed. Additional circuits shall be added to the panel located in the main office area (see additional photo in the Revised Attachments for panel information).

ii. The Project office is easily accessible via paved road off State Route 8 in Colebrook, CT. This is a remote area, but all amenities are available within thirty minutes of the project office. Utilities are available on site.
