BIM-FM in existing buildings: a case study on educational and high-rise residential buildings

Abstract

Purpose Facility management (FM) is regarded as an emerging issue in civil engineering and is responsible for ensuring the building's expected performance. The purpose of this study is to analyze buildings' current FM processes for educational and high residential segments and propose an FM-building information modeling (BIM) (BIM6D) to understand the information flow and leading players with and without FM-BIM integration. Design/methodology/approach The research strategy was a case study with data from the FM process of two buildings. This study was carried out in three stages: diagnosis of FM of the two buildings, FM-BIM integration and information flow and leading players analysis. Maintenance activities were categorized according to periodicity and status criteria for each project element for FM-BIM integration and were visualized in the Revit design using Dynamo software. Findings The results of this study show differences in how FM is conducted, especially in formalization and preventive character, and similarities regarding the difficulty of foreseen and lack of control because of scattered, disconnected and incomplete information on both. The visual appeal of the FM-BIM integration facilitates information access. It optimizes the use of the digital model through the most prolonged phase of the life cycle of a building (post-occupation phase). However, FM-BIM challenges buildings that do not have digital model expertise as residential segments. This study suggests a more significant role for construction companies in these cases. Originality/value This study investigates BIM-FM integration of buildings in two different contexts and reveals the importance of a construction company's role in buildings in the residential segment. This study contributes with real-life cases on BIM in existing buildings, discussing the value and challenges of BIM in FM applications.
