Issues such as lack of standardized process to develop FM data during design and construction stages, Standardized data format for data transfer, and fragmented databases are highlighted in multiple BIM-FM research. COBie defines when, how, and what data needs to be captured for FM purposes. However, previous research combined with explorative studies highlighted several challenges with handling the COBie datasheet, especially its widely used spreadsheet format. This study aims to identify the issues associated with COBie handling (especially its spreadsheet format) and propose a COBie Dataset Management System framework (CDMS) to help solve these issues. In developing the proposed CDMS framework, a critical review of the published articles related to the COBie datasheet has been conducted. An exploratory study using a BIM Model was conducted along with the literature review to understand the key challenges highlighted in the reviewed articles. Based on the identified key issues, underlying reasons were recognized, and key ideas for the framework have been developed, potentially solving these key challenges. The research finding will help develop COBie-centric applications and enhance the entire COBie data capturing workflow.

This LCEP was characterized by Fourier transform infrared spectrometry, 1H and 13C NMR spectroscopy, differential scanning calorimetry (DSC), and polarized optical microscopy (POM). LCEP was then blended in various compositions with DGEBA and cured with a room temperature curing hardener. The cured blends were characterized by DSC and dynamic mechanical analysis (DMA) for their thermal and viscoelastic properties. The cured blends exhibited higher storage moduli and lower glass-transition temperatures (tan δmax, from DMA) as compared with that of the pure DGEBA network. The formation of a smectic liquid-crystalline phase was observed by POM during the curing of LCEP and DGEBA/LCEP blends. © 2003 Wiley Periodicals, Inc.

A popular assumption holds that increased investment in safety improves safety performance. However, close examination of previous studies on safety investments reveals that the relationship between the level of safety investment and safety performance remains debatable. The purposes of this study are therefore to (1) test the relationship between safety investment and safety performance, and (2) identify factors influencing their relationship. The research approach for collecting the data is by means of structured interviews. The findings indicate that safety performance is positively related to safety investments when the influence of project hazard level is removed. The effect of safety investments on safety performance was found to be more significant for projects with high hazard levels than those with low hazard levels. The interactive effects of safety investments and project hazard levels on safety performance imply that in order to achieve good safety performance under different project conditions, different investment decisions in workplace safety need to be made.

The purposes of this study are to identify critical factors hindering BIM implementation in Singapore's construction industry, analyze their interrelationships, and identify strategies for reducing these hindrances. The results from a survey of 87 experts and five post-survey interviews in the Singaporean construction industry identified 21 critical hindrances, among which "need for all key stakeholders to be on board to exchange information" was ranked top. These hindrances were categorized into lack of collaboration and model integration (LCMI), lack of continuous involvement and capabilities (LCIC), and lack of executive vision and training (LEVT). LEVT and LCIC contributed to LCMI; LEVT caused LCIC. The proposed framework implying the key hindrances and their corresponding managerial strategies can help practitioners identify specific adjustments to their BIM implementation activities, which enables to efficiently achieve enhanced BIM implementation. The hindrances identified in this study facilitate overseas BIM implementers to customize their own lists of hindrances.

The main objective of the research project being discussed here was to identify impediments to the development of online communities of learning and to suggest how these may be overcome so that students could benefit from the enhancements that online learning communities bring to communities of practice in students workplaces. While communities of practice develop quite naturally among people working in the same physical space, as people learn from each other as they carry out their tasks at work, they are more difficult to establish in an online setting. Interviews were carried out with students and teachers and the data collected are described. Differing designs of courses, particularly the role of the teacher and the size of the classes, are considered and learning community development in both blended and distance learning envi...

A postal survey of contractors in Singapore was conducted to test the framework. It is found that site accidents are more likely to happen when there are inadequate company policies, unsafe practices, poor attitudes of construction personnel, poor management commitment and insufficient safety knowledge and training of workers. It is recommended that project managers pay more attention to the important factors identified in this study to help them enhance performance at construction sites and reduce the frequency of accidents.

Thus, BIM implementation needs to be enhanced. The objectives are to identify the critical success factors (CSFs) for enhancing BIM implementation and investigate the interrelationships among these CSFs. 32 success factors were identified through a literature review and a questionnaire survey was conducted. The results indicated that 15 CSFs were identified and grouped into integration and accuracy of models (IAM), commitment and training from the management (CTM), and advantages and support of implementation (ASI) through factor analysis. The results from structural equation modelling (SEM) analysis revealed that CTM resulted in IAM and from ASI, while ASI facilitated IAM. The proposed framework indicating the CSFs and the intergroup relationships provides an in-depth understandi...

While it questions the effectiveness of the traditional approach to risk scoring, the literature provides no alternative satisfying all the criteria stressed by the critics. In fact, different dimensions of uncertainty, along which a risk can be viewed, entail different quantifications. Most previous work, however, concentrates on supposedly all-purpose solutions that are often justified or promoted over others by reasons not necessarily applicable; little information is available on how to best select the needed scoring approach. This research investigates the issues involved in constructing a risk factor formula that is more consistent with the nature of the project and its goals. Major concerns addressed in the literature are organized, serving as a basis to evaluate and improve seven groups of alternative formulas in light of mathematical arguments without which fallacious conclusions-such as the myth that importance is implied by exponents greater than one-would be inferred. These groups are complemented by a multifaceted approach introduced for the first time in this paper, providing the observer with customized information about risks. A robust scoring system founded on these results will ensure that allocated risk factors are neither too high nor too low. Although expressed in the terminology of construction safety, the findings of this research can be extended to other industries that feature some element of uncertainty.

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 ...

This study aims to investigate the factors influencing BIM diffusion and examine how the factors influence firms with different project roles, firm sizes, and BIM implementation experience. The results of a pilot study, a questionnaire survey with 89 professionals, and five post-survey interviews showed that hindrances related to inadequate multi-party collaboration (whether formal or informal), conservative mindset, limited skills, costly infrastructure and training, and multi-discipline model integration were the most influential, whereas drivers associated with project leadership team’s strategic consensus, multi-disciplinary design coordination, training, and government regulations were top-ranked. Subgroup analyses between pairs of firms with different characteristics revealed that while construction firms and less experienced stakeholde...

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...
