    Development of a rule-based system to enhance the data consistency and usability of COBie datasheets
    (Oxford University Press, 2020-12-18) Kumar V; Teo EAL
    Building information modeling (BIM) for facilities management (FM) has been gaining considerable attention. Construction operations building information exchange (COBie) datasheets are conceptualized as an electronic format of data for FM handover extracted from the BIM model and supplemented with information from other sources. To build an efficient COBie datasheet, it is advocated to build and verify data at all stages of design and construction, commonly known as data drops. Nevertheless, data consistency verification is a difficult task pertaining to COBie's complex structure and data representation. This study aims to understand the challenges associated with the COBie datasheet verification and consistency checking process, especially during data drop stages, and develop a solution to mitigate these challenges. The study uses a combined methodology of design thinking and waterfall model from the software development process. The outcome of the research study manifests in a prototype application. The prototype application can help in verifying COBie datasheet consistency during data drop stages. Additionally, this study proposes a new dimension to utilize the COBie datasheet to track various asset-related changes in a project by comparing COBie datasheets and visualizing this data in a visually interactive manner using a property graph model.

    Evaluating the Roadmap of 5G Technology Implementation for Smart Building and Facilities Management in Singapore
    (MDPI (Basel, Switzerland), 2020-12-08) Chew MYL; Teo EAL; Shah KW; Kumar V; Hussein GF
    The concepts of smart building (SB) and smart facilities management (SFM) are crucial as they aim to uplift occupants’ living standards through information and communication technology. However, the current network possesses several challenges to SFM, due to low bandwidth, high latency, and inability to connect a high amount of IoT (Internet of things) devices. 5G technology promises high-class network services with low latency, high bandwidth, and network slicing to achieve real-time efficiency. Moreover, 5G promises a more sustainable future as it will play a crucial role in reducing energy consumption and shaping future applications to achieve higher sustainability goals. This paper discusses the current challenges and benefits of implementing 5G in various use cases in SFM applications. Furthermore, this paper highlights the Singapore government rollout plan for 5G implementation and discusses the roadmap of SFM use case development initiatives undertaken by 5G Advanced BIM Lab (Department of Building, National University of Singapore) in alignment with the 5G implementation plan of Singapore. Under these 5G SFM projects, the lab seeks to develop state-of-the-art 5G use cases in collaboration with various industry partners and developed a framework for teaching and training to enhance students’ learning motivation and help mid-career professionals to upskill and upgrade themselves to reap multiple benefits using the 5G network. This article will serve as a benchmark for researchers and industries for future progress and development of SFM systems by leveraging 5G networks for higher sustainability targets and implementing teaching and learning programs to achieve greater organizational excellence.
