SECONDARY CONDUIT AND CONDUCTORS ARE TO BE ROUTED THROUGH NEW PRIMARY VAULT ENROUTE TO THE EXISTING McCHORD SIGN JUNCTION BOX. CONDUIT AND CONDUCTORS CAN BE ROUTED DIRECTLY TO THE SIGN JUNCTION BOX ONLY WHEN PULLING CALCULATIONS ARE SUBMITTED TO GOVERMENT DEMONSTRATING THAT THE MAXIMUM PULLING TENSION AND SIDWALL PRESSURE IS NOT EXCEEDED IN ANY BEND PER JBLM/NEC CRITERIA. AN ALTERNATE SOLUTION IS TO PROVIDE AND INSTALL SMALL HANDHOLE ENROUTE PRIOR TO INTERCEPTING THE SIGN JUNCTION BOX - THUS MINIMIZING THE NUMBER OF BENDS.

13.8 kV DISTRIBUTION LINE DUCTBANK

(SEE SHEETS C-103 AND C-104 FOR UTILITY LAYOUT)

Work occurring around the existing Perimeter Security Fence (i.e. excavations, bore pits etc) must continue to maintain the secure conditions as provided by the cantonment fence. Any breach in the security fence will require supplemental measures be made by the contractor to ensure continuous perimeter security is maintained (i.e. supplemental temporary fencing etc.) in coordination with Security Forces criteria.

General Note: As part of the contractor’s ‘Means & Methods’ of accomplishing work, the location of bore pit(s) and length of bore can be adjusted in the field to allow for providing adequate clearances around existing utilities which are to be encountered as identified per the underground ductbank and boring profiles depicted
