The purpose of this paper is to describe the technical features, underlying concepts and implementation details of a novel Building Information Modeling (BIM)-integrated, graph-based platform developed to support BIM for facilities management through a usability driven visual representation of the construction operations building information exchange (COBie) spreadsheet data.
This paper is based on the iterative steps of design thinking and agile software development methodology. The conceptual development of the VisualCOBie platform is based on Gestalt’s principles of visual perception to facilitate usability and comprehension of the COBie data.
The paper demonstrates that Gestalt’s principles of visual perception provide a suitable conceptual as well as implementable basis for improving the usability and comprehension of COBie spreadsheets. The implemented BIM-integrated, graph-based VisualCOBie platform supports visual navigation and dynamic search, reducing the cognitive load of large spreadsheets that are common in facilities management software.
The usability, visual search and dependencies-based search of VisualCOBie can potentially transform how we implement and use facilities and information management systems in construction, where large spreadsheets are frequently used in conjunction with BIM and other tools. VisualCOBie also provides usability-based step towards BIM for facilities management.
The VisualCOBie approach provides a novel user interface and information management platform. This paper may also foster a potential paradigm shift in our approach to the representation and use of information exchange standards such as COBie, which are required to facilitate the research and practice on BIM for facilities management.

Until now, the usage and usability factors associated with AEC–FM standards have remained largely overlooked. This oversight could be a potentially significant factor in the adoption rates as well as effective utilization of such advanced solutions in the AEC–FM industry. Therefore, from a conceptual and theoretical viewpoint, the purpose of this paper is to address this gap in understanding and enhancing the usability aspects of standards such as construction operations building information exchange (COBie) over its spreadsheet representation. Besides, findings from this study and the proposed theoretical fundamentals to enhance the usability and functionality of COBie spreadsheet representation could potentially lay the foundation for a VisualCOBie approach.
The iterative steps of design thinking and agile development are harmonized to form the main research methodology. Design thinking is useful in problem (re)formulation, and agile development is useful in iterative software development. The approach aims to identify and understand the needs and requirements of the AEC–FM users from the standardized approaches and associated IT solutions; and formulate the main features and functionalities of the proposed solution. The methodology supports the aim of generating a broad range of possible solutions instead of coming up with the “right” solution.
Despite the standards and associated IT developments, the AEC–FM industry still suffers from inefficient information management. To date, most initiatives have focused on utilization of the outputs from different IT solutions in terms of accuracy and completeness of the data defined in the standards. This research found that well-established standards such as COBie and corresponding IT solutions are not merely technical issues, but it is equally important to understand how the end-users cognitively perceive and process them. The developed solutions need to address user point of view to facilitate wider utilization of these standards in practice.
In this research, Gestalt’s visual perception principles have been used to evaluate the usability issues of COBie spreadsheet. Although Gestalt principles provide a valid and proven viewpoint, there can be other cognitive principles that could also be taken into consideration.
The usage and usability factors associated with AEC–FM standards have remained largely overlooked, indicating a gap in the literature. This gap was considered as a potentially significant factor in the adoption as well as effective utilization of such standards and advanced solutions in the AEC–FM industry. By grounding the research in cognitive and usability perspectives of information exchange standards, the authors demonstrate how such theoretical underpinning can lead to innovative solutions.

The purpose of this paper is to examine the factors that influence farmers' preference for the use of Islamic banks in Turkey and to investigate their knowledge level and perception about Islamic finance.
Survey data used in this study is obtained by drawing a sample of 1902 farmers who are members of the Agricultural Credit Cooperatives Union (ACCU) from 37 provinces of Turkey. Pearson's Chi-square test is used to analyze the association between the demographic features of farmers, conventional bank usage and Islamic bank usage. Binary logistic regression model is used to estimate the factors influencing the preference for Islamic banks. Explanatory variables include knowledge on Islamic banking and finance, perception of compliance to religion, saving ability and cost concern along with the control variables of Islamic bank branch number in the region and age of respondent. Robustness check is conducted via alternative models using ordinary least squares (OLS) and logistic regression.
Less than 10% of the participant farmers use Islamic banks and 59% declare they know nothing about Islamic banking. Age, education level, income level, nonagricultural income level, saving ability, duration of working in agriculture, land size and region are significantly related to farmers' preference of using Islamic banks. Knowledge level, perception of religious compliance, saving ability and cost concern are statistically significant factors that influence the probability of using Islamic banks.
This study does not include the analysis of the relationship between being religious and using Islamic banks because questions related to the assessment of religious practice were excluded due to the ACCU's sensitivity to investigate personal beliefs. Therefore, future studies can expand the scope of this research by investigating religiousness. The sample is chosen from the ACCU members who are already benefiting from a formal source of credit; therefore, the results should not be attributed to all farmers.
Islamic banks and microfinance institutions' further engagement in the agricultural sector and ACCU's implementation of Islamic finance instruments.
Islamic banks' further diversification in the agricultural sector and ACCU's implementation of Islamic finance instruments.
To the best of the authors' knowledge, this paper is the first to investigate the farmers' perception and preference of Islamic banking in Turkey. The sample size of 1902 is much larger and geographically diversified compared to studies in agricultural finance. This study will be valuable for the agricultural finance empirical studies in Turkey as well as an important addition to the emerging literature on Islamic finance.
