Abstract: A method for generating an interactive stacking plan of a building is disclosed. A building data file with one or more external tenant records in a first format is received on a server computer system. Data values of one or more of the external tenant record fields are imported into master tenant records, each of which is defined by a plurality of master tenant record attributes. Stacking plan graphical elements are generated for each of the master tenant records with a size proportional to a leased space. A user-activatable link that generates an independent display of at least one of the master tenant record attributes is included in the stacking plan graphical element. The stacking plan graphical elements are arranged in the interactive stacking plan according to the floor identifier attributes of the corresponding master tenant records. The interactive stacking plan is then transmitted to the client computer system.
