I would verify the voltage of the building first with a plug-in voltmeter in random outlets before using the vacuum. Most industrial buildings run on 220v and that will cook that vacuum in less than a minute. If 220v you might need to buy a step-down transformer to convert 220v to 120v in order to use it.
If the voltage is safe to use, I would recommend gluing some strong magnets to the front of the brushroll to catch paperclips and thumbtacks and whatnot. Also like others have said, a longer, tougher, industrial vacuum cord would help too, since the outlets in offices and other industrial buildings are spaced few and far between.
