The work led to integration between the two informative systems, by relating them and allowing for an easy switch from one system database to the other. This integrated framework is intended to enable facility managers to easy visualize in the GIS platform, through queryable 2D maps with 3D modeling relevant to information from BIM to efficiently manage.
