when a plurality of respective first work machines of the plurality of first work machines are determined to have a respective progress rate equal to or larger than the threshold, the instruction unit instructs the second work machine to take over construction of a respective construction range from a respective first work machine closest to the second work machine.
8. The construction system according to claim 2 , further comprising
an input unit configured to receive an input of the threshold of the progress rate.
9. A construction system using:
a first work machine that is controlled by manual operation; and
a second work machine different from the first work machine, includes a vehicle body and a second working equipment, and configured for automatically controlling the second working equipment based on at least one of a current terrain and a designed terrain of a construction range, and a tooth-edge position of the second working equipment, the construction system comprising:
