Abstract: A system and method are herein disclosed for site and tower information modeling and management. The site and tower information contains data for the physical and functional characteristics of objects at a site and tower and engineering projects managing such data. Site and tower profile may be defined to identify data of a particular site and tower. Asset portfolio may be defined to manage a group of site and tower profiles. Engineering tasks may be defined to manage specific changes-related engineering work at a site and tower. Configurations may be defined to manage the settings, selections, and assumptions for design criteria and analysis option for engineering tasks. Configurations of information categories may be defined and combined to define site and tower information models. 2D and 3D visualizations may be generated to review and edit site and tower information models. Tenant projects may be created to manage engineering tasks.
