The present disclosure provides a construction management system capable of ascertaining information about a construction site more accurately than before. A construction management systemcomprises: a position sensordetecting position information about a transport vehiclethat transports payload; a position sensordetecting position information about a loading machinethat loads payload onto the transport vehicle; a weight detection devicedetecting weight information about the payload held by the loading machine; and an information management controllerwhich, based on chronological information of the position information about the transport vehicle, chronological information of the position information about the loading machine, and chronological information of the weight information, calculates the load weight of the payload loaded onto the transport vehicle

Work management system

A site management system is provided with a server that acquires information about a construction machine and a construction machine operator at a construction site through a communication channel, and manages work conditions at the construction site. The server includes an information registration unit that acquires and registers position information, acceleration data, and gyro data of the construction machine and the construction machine operator, and a riding determination unit that determines a proximity state between the construction machine and the construction machine operator from the position information of the construction machine and the construction machine operator, and determines whether or not the construction machine operator is riding the construction machine from the acceleration data and gyro data of the construction machine operator in addition to the proximity state.

Site management system

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.
