Abstract: A system for construction management includes a scannable job site code that is scanned by a user's device to determine which property the user is at and to initiate work by the user (e.g., craftsman or team) at that property. The system for construction management includes a database having activities to be performed (e.g., construction activities), definitions of users (e.g., craftsman or teams) and construction managers. The system for construction management provides accurate communications between the craftsman/teams and the construction managers, reducing messaging and phone calls to the construction manager. The system for construction management provides direct communications between craftsman/teams and other craftsman/teams as well as the construction managers, reducing messaging and phone calls, e.g., to the construction manager.
