BMS are deployed to manage buildings such as Shopping malls, office, and residential complexes. However, the information needed for their efficient functioning are either incomplete, generated separately, or  hard to determine. BIM generates and stores useful integrated information during design and construction phases of the building projects.  These Information are well utilized during design and construction stages but their usage in FM stage is limited.  The guidelines and standards to facilitate BIM model during design and construction stages, are not considered critically usable. Hence, this paper aims to identify the need for crucial asset information during FM practices while executing the BMS process, to develop a standard framework for information specifications during the early development of BIM model, and utilize the same as a source for BMS in FM processes. Nevertheless, this paper addresses the common FM practices and its building data requirements towards efficient BMS implementation pivotal to the mechanical and electrical systems for a conceptual framework of a BIM model. The research adopts deductive approach through semi-structured qualitative interviews with FM stakeholders of the malls in Saudi Arabia to obtain the standard FM data requirement from client perspective, while managing the FM process through a BMS system.
