  • Patent number: 11748826
    Abstract: A construction site management device receives operation information indicating an operation content of a loading machine, and positional information sent from a haulage vehicle; stores a positional history, and stores an operation history. The operation history includes a content of work of the loading machine performed in a work area and information of time when the work has been performed. Haulage history indicates when the haulage vehicle has entered the work area, and loading history indicates the time when the loading machine has performed loading work for the haulage vehicle and a work area in which the loading machine has performed the loading work for the haulage vehicle. The loading history is created on the basis of the haulage history and the operation history; and work result data indicating from which work area to which work area a load has been hauled is output.
