Campus utilities are distributed through 4 miles of underground tunnels. The tunnel system is controlled, monitored, and maintained 24 hours a day by the Utilities & Energy Department. 

Tunnels are Confined Spaces and entry must be authorized by the U&E Control Room. Departments and Contractors who need to access the UO Tunnel System are required to watch the Tunnel Entry Training Video and fill out the Tunnel Entry Briefing Form, which can be done online. Once complete, the form must be turned into the Control Room at U&E.

A Tunnel Work Authorization Request (TWAR) form is required for any work planned to be done within the Tunnel System. TWAR's must be submitted to U&E for review and approval prior to entry and start of work.
