When we approached our electrician and said “we are going to rip all of the wires out of our walls” he replied like you would expect: are you crazy? With constant continuous improvement activities, we need the flexibility to move around offices, computers, and machines without having to pull wires through walls and figure out how to patch old holes. It was a little hard to tear apart walls that are only 6 years old but we decided to plan it out and do it anyway.
Our solution to have a more flexible office (and wiring) was to build overhead cable trays. The trays form a halo around each room and all route from the main servers to each area of the plant. Along the way we also made some significant improvements to our ventilation system (positive pressure with an HRV, full zoning of every room, and increased filtration capacity) and found ways to make the offices easier to clean.
CAUTION TO READERS: many terrible *before* pictures to follow and they aren’t pretty!
The wire drops from the tray are surface mounted and have a subtle industrial look.
