A customer of ours had ask us to come in and pre-run cables for them. They handed us a floorplan to follow and to have everything ready so once the cubicle is installed, we’ll just come in and drop them to each cubicle. The problem came when we arrived the day to drop the cables and the customer had changed the floor plan. This had cause 50% of the cables that was original ran to now being too short and unusable. We had to spend another couple day of work to sort what is useable and running new cables for the remaining amount.
