A system for managing construction projects includes a database, a component interface, a state interface, and a database interface. The component interface is operative to receive component identifiers identifying components of a construction project. The state interface is operative to receive state indicators, each state indicator indicating a particular state (e.g., ordered, in transit, installed, inspected, etc.) associated with one of the components. The database interface is operative to store the component identifiers and the associated state indicators in the database. A method of managing construction projects is also described. The method includes the steps of receiving a plurality of component identifiers from a user, associating an initial predefined state with each received identifier, storing the component identifiers and the associated initial states in a database, updating the states associated with the component identifiers in the data base, and retrieving the updated states from the database to determine the status of the construction project. Novel data structures, application program interfaces, and graphical user interfaces are also disclosed.
