Inventory before demolition
Walk the plant while the cable is still installed and record what is on each tray and feeder. Once it is on the ground, identification depends entirely on the print.
Segregate at removal
Keep constructions apart as they come out: medium voltage, tray, control, instrumentation, building wire. Mixed piles at this stage cost more to sort later than they save in labour now.
Preserve the tags
Reel tags, drum numbers and cable schedules are the documentation that supports a reuse basis. Photograph and file them while the plant records still exist.
Phase the collections
Agree a collection rhythm rather than one enormous pickup at the end. Phased moves reduce storage pressure and let the review keep pace with removal.
