This paper introduces a set of analyses using location specific GIS data to inform certain preconstruction and construction activities performed by contractors. Five types of GIS assessments whose output provides information for project risk analyses, site logistics, site security, and safety are discussed. The results from these analyses show that the information obtained could be beneficial for contractor’s decision making and construction planning. Additionally, a hypothetical project was created to provide context for the integration of BIM and GIS to support the operations and maintenance of mechanical equipment. A practical workflow is proposed that includes specific building information and steps in the process to import BIM project data into GIS software for visualization of a building asset location. As proof of concept, Air Handling Units (AHUs) data was input to the Revit® model element, which was then exported as a text file and imported to ArcMapTM. The workflow can be applied to a single building or several buildings in a broader site like university campuses. This paper contributes to the literature with 1) its application of GIS data for preconstruction and construction analyses, and 2) a workflow that integrates BIM and GIS data using commercial off-the-shelf (COTS) software.
