Abstract
A construction machine management system includes a detection sensor unit installed in a construction machine that is movable in a work site area and a position recognition unit that recognizes position information regarding a position of work executed in the work site area using a movable work tool included in the construction machine based on a detection result obtained by the detection sensor unit with respect to an external indicator installed in the work site area and a detection result obtained by the detection sensor unit with respect to a movable indicator attached to the movable work tool.
