discussion, From my experience working for a plumbing subcontractor that handles a lot of maintenance work for buildings, there is a lot of time spent trying to locate a shutoff valve, specific pipe, etc. which is ultimately time that is charged to the building owner. BIM can significantly aid in maintenance repairs over a building's life by providing detailed, up-to-date digital models that include the exact specifications and locations of all building components, allowing for quicker identification and resolution of issues
