At exhibitions a careful schedule needs to be created for access to docks - and this needs to be adhered to. A truck arriving late or going to the wrong dock can be amplified throughout the whole shut down. Support equipment needs to be on hand such as folklifts and cranes. The event manager may find it more cost effective to buy or make the equipment necessary for the event and sell it afterwards. The large floating lanterns at the New Years Eve celebrations in Sydney were an example of this.
Small equipment is a problem as it can easily get lost or stolen.
The handheld two way radios are often just left on the stage after use. Huge equipment will require special thought as to its removal. At a recent Mining Equipment Exhibition almost all work had to stop while one of the huge trucks on show was removed from the site. Barricades at events need to have a schedule for dismantling as they can create bottlenecks in the traffic. Many artists do not have the 'invoice cycle' of large firms and there fore need to be paid as soon as the performance is finished rather than after 90 day.
