Inquiry #9: Special provision 5-1.36C(3) states "San Francisco Muni's overhead contact system (OCS) shown at the intersection of California Street and Park Presidio Boulevard will not be de-energized.

require de-energizing. If temporary de-energizing of the OCS is needed...You are responsible for any delays and costs incurred to de-energize and re-energize the OCS."
