I was under contract to remove wall mounted data racks from multi tenant buildings in Massachusetts. In order to remove one rack that was used by the company I was under contract for some wires were cut that were owned by an other company. These wires had been placed into the top and passed through the bottom of the rack that was to be removed. The only way to remove the rack was to cut the wires. The wires were two Cat5E wires. The other company expects me to pay for the damage caused by the cut wires however I have said that they had no right to install their wire through our equipment. WHO IS RIGHT???
