S. and worldwide. However, efficient integration of BIM with Facility Management (FM) Systems has not yet been achieved [1] . One of the main reasons is that FM systems require accurate as-built information, and accurate as-built BIM models are not typically required in the contracts as part of the project deliverables. This is mainly due to the fact that majority of the owners are not yet fully aware of the benefits BIM has to offer [2] . Moreover, it is even more difficult to obtain/create as-built BIMs for existing buildings and industrial plants since there is no design 3D BIM model exists for these buildings, therefore an as-built BIM model would need to be built from scratch using 2D asbuilt drawings and project specifications.  \nIntegrated BIM-FM systems offer significant benefits to owners such as better visualization of the spaces to be maintained in a virtual environment. BIMs are reviewed on a regular basis during project coordination meetings between various stakeholders, and are updated regularly during the construction phase. However, some coordination issues maybe realized within the BIM, but fixed in the field; and those changes are not typically reflected in the BIM since delivering an accurate as-built BIM model is not required as part of the project deliverables. Instead, 2D as-built drawings are produced from BIM models, manually updated to reflect the as-built conditions, and handed over to the owner. Typically, these 2D as-built drawings are not linked to any of the FM information systems such as computerized maintenance management systems (CMMS), electronic document management systems (EDMS), energy management systems (EMS), and building automatio","cbCaiur3fNapU8ni","https://ap.wps.com/l/cbCaiur3fNapU8ni","pdf",363776,"English","# 1 Introduction\n## Building Information Modeling and FM Integration Challenges\n## As-built Data Acquisition Technologies\n## Scan-to-BIM and Current Software Limitations","[{\"question\":\"Why is BIM integration with Facility Management (FM) still difficult?\",\"answer\":\"FM systems require accurate as-built BIM, but accurate as-built BIM models are not commonly required in project deliverables.
