The complete service of receiving exhibit freight at the loading dock or advanced warehouse, transporting it to the exhibitor’s booth space, storing empty containers during the show, returning empties at the close of the show, and moving packed materials back to the loading dock for outbound shipment. Material handling is provided exclusively by the show’s official general contractor and is billed by weight. It is one of the most significant and frequently misunderstood cost items in an exhibitor’s show services budget. Also referred to as drayage.
