I was in E/I at McClellan AFB California from 89-97. The last project i worked on with MH and duct system was in 94 at Mountain Home. When the BRAC started to close the active E&I units, these type of installation started to slow down.
When I was in Korea in 1998, a guard team was doing CITS phase I, which included MH & duct system with fiber install.
When I got to Ramstein AB Germany in 1998, another guard team was finishing up with the CITS phase I install there. After that, any projects that the Communication Squadron Planning and Impamentaion flight generated which included MH & duct systems, was done mostly by contractor.
The only projects at that time and currently at that base which CE has anything to do with MH & duct systems other than maintaing, is with MILCON prjects. Currently any project that the Comm. SQ. generates, is done by contractor.
