A contractor is rehabilitating a bridge over a navigable waterway. The construction contract allows for the navigable channel to be closed for pier repairs for short durations, provided that the channel can be cleared within one hour of a Coast Guard request. Failure to do so will result in a hefty fine and project shutdown. The contractor decides to hire a tug boat with operator on standby for the length of the project to better facilitate swift removal of work barges from the channel.
