Abstract
A management device includes a ticket issuance unit that issues a ticket indicating work related to a construction site, a position information acquisition unit that acquires position information of a communication terminal acquiring the ticket, and an output unit that outputs the position information of the communication terminal selecting the ticket regarding the same construction site among the position information acquired by the position information acquisition unit.
Claims20
A construction management method comprising the steps of:
- creating a group by a server device;
- issuing a work ticket associated with the group;
- issuing a ticket code for adding a communication terminal to the group, the ticket code being included as information of the work ticket;
- accessing the server device from a first communication terminal owned by a first operator of a transport vehicle or a construction machine;
- adding the first communication terminal to the group by entering the ticket code by the first communication terminal;
- transmitting, by the first communication terminal, a position information of the first communication terminal to the server device;
- and
- transmitting, by the server device, the position information of the first communication terminal to a second communication terminal based on a request from the second communication terminal, the second communication terminal owned by a second operator and has already been added to the group.
