How long does it take to wire a large fireworks display to its computer system?

A large fireworks display, such as the Boston, Mass Independence Day celebration, takes at least a week to wire into its computer system. The construction of the display and the wiring of it is very dependent on environmental elements. High humidity, altered terrain, and even human environmental factors such as local law enforcement and fire prevention teams can cause the process to slow down, be restarted, or even be halted altogether.
