- Excavation of existing material around existing foundations.
- Repairing the existing fence.
- Installation of asphalt around existing transformer and tower foundations.

Substation MSB and the elimination of any potential future malfunctions
which could cause power outages and/or damage to equipment. 
- Switchgear (cabinet) was 3 1/2" to 5 1/2" out of line
and required jacking and levelling. Concrete was placed on top and underside
