Abstract: A construction management system includes a current terrain data creation unit that creates current terrain data of a construction site on which a work machine operates, a detection data acquisition unit that acquires detection data of a detection device that detects the construction site, a reflection unit that generates reflection data in which the detection data is reflected in the current terrain data, and an output unit that outputs the reflection data on a display device.

Abstract: A state data acquisition unit acquires state data indicating a state of a work machine at a plurality of times. A work determination unit determines a classification of a work of the work machine for each of the plurality of times based on the acquired state data. A period determination unit determines a start point and an end point of a period related to a predetermined classification among determined classifications of works. An index-value determination unit obtains an index value of the state of the work machine from the start point to the end point.

Abstract: A work analysis device includes a state data acquisition unit state, a work specification unit, and an output unit. The data acquisition unit acquires state data indicating a state of a work machine. The work specification unit specifies, based on the acquired state data, a classification of work of the work machine for each of the multiple times, and collects the classification of work in a chronological order. The output unit outputs a time series of the specified classification of work.
