The usability aspect of the construction operations building information exchange (COBie) datasheet has been largely overlooked. Users find it difficult to find relevant data inside COBie and understand the dependencies of information. This research study is a part of a more comprehensive research study to identify the usability issues associated with COBie and propose solutions to deal with them. This paper aims to discuss the challenges associated with the visualization aspect of COBie and proposes a solution to mitigate them.

This paper is based on design thinking and waterfall methodology. While the design thinking methodology is used to explore the issues associated with the visualization aspect of COBie, the waterfall methodology is used to develop a working prototype of the visualizer for the COBie datasheet using a spreadsheet format.

The paper demonstrates that the property graph model based on a node-link diagram can be effectively used to represent the COBie datasheet. This will help in storing data in a visually connected manner and looking at links more dynamically. Moreover, converting and storing data into an appropriate database will help reach data directly rather than navigate multiple workbooks. This database can also help get the history of data inside the COBie datasheet as it develops throughout the project.

This research proposes a novel approach to visualize the COBie datasheet interactively using the property graph model, a type of node-link diagram. Using the property graph model will help users see data in a connected way, which is currently missing in the spreadsheet representation of COBie data. Moreover, this research also highlights that storing historical changes in COBie data can help understand how data has evolved throughout the construction. Additionally, structured storage of data in relationship format can help users to access the end of connected data directly through the efficient search.

Until now, the usage and usability factors of Construction Operation Building information exchange (COBie) datasheet have remained largely overlooked. This oversight may be the potential factor in the lower adoption rates as well as the effective usage of COBie datasheet in the architecture, engineering and construction-facilities management industry. The purpose of this study is to investigate the benefits and key issues associated with COBie datasheet handling and identify the key technological solutions, which can help in mitigating the identified issues.

A literature review was conducted to identify the key benefits of using COBie and issues, which are associated with COBie datasheet handling. This paper has also designed a questionnaire based on a literature review and surveyed professionals who are well versed with handling COBie datasheet. Using responses, the issues are analyzed and discussed using non-parametric statistical analysis.

A total of 9 key benefits and 24 key issues categorized under three groups of usability issues, technical issues and organizational/other issues were identified. The results from the survey agree with all the key issues associated with COBie datasheet handling (with 86 responses). This research also proposes key ideas, that can help in mitigating these issues.

There is a paucity in published literature, which discusses in detail about the various issues associated with COBie datasheet handling. This research study aims to address this gap by identifying key issues by looking at the entire COBie data-capturing process holistically. Finding from this study can help professionals to understand these issues and develop appropriate technological solutions, which can make COBie data capturing and understanding easier. The findings could also assist in increasing the adoption rate of COBie, which could be achieved through mitigation of identified issues.

The purpose of this paper is to identify critical non-value adding (NVA) building information modeling (BIM) implementation activities in current building project delivery process, develop a BIM implementation readiness (BIMIR) evaluation model, and assess BIMIR statuses in building projects in Singapore.

A questionnaire survey and four post-survey interviews were conducted in Singapore. A fuzzy synthetic evaluation approach was adopted in the model development.

In total, 38 out of 44 NVA BIM implementation activities were deemed critical and used in the proposed model, among which “lack of involvement by contractors to contribute site knowledge” in the design development phase was ranked top. This model was validated in five projects. It was found that most of 73 surveyed building projects were in a low BIMIR status and the assessment results were consistent with current industry practices of BIM implementation in Singapore.

There may be geographical limitation on the identification of the critical NVA BIM implementation activities. However, because BIM mandate spreads globally, the findings can help overseas project teams customize their own NVA activities and evaluation models.

As BIM implementation is mandated in Singapore, BIMIR evaluation helps local project teams identify weak areas of their BIM implementation activities and prioritize resources to enhance those areas.

No tool has been developed for evaluating BIMIR at the project level in the construction industry in Singapore or at large in Asia. Four BIMIR statuses are defined, which are consistent with Singapore’s BIM guidelines and standards.

Despite recognition of its importance to Singapore’s economy, the construction industry is plagued by poor safety and productivity performance. Improvement efforts by the government and industry have yielded little results. The purpose of this paper is to propose a framework for developing a productivity and safety monitoring system using Building Information Modelling (BIM).

The framework, Intelligent Productivity and Safety System (IPASS), takes advantage of mandatory requirements for building plans to be submitted for approval in Singapore in BIM format. IPASS is based on a study comprising interviews and a questionnaire-based survey. It uses BIM to integrate buildable design, prevention and control of hazards, and safety assessment.

The authors illustrate a development of IPASS capable of generating productivity and safety scores for construction projects by analysing BIM model information.

The paper demonstrates that BIM can be used to monitor productivity and safety as a project progresses, and help to enhance performance under the two parameters.

IPASS enables collaboration among project stakeholders as they can base their work on analysis of productivity and safety performance before projects start, and as they progress. It is suggested that the BIM model submitted to the authorities should be used for the IPASS application.

IPASS has rule-checking, hazards identification and quality checking capabilities. It is able to identify hazards and risks with the rule-checking capabilities. IPASS enables practitioners to check mistakes and the rationality of a design. It helps to mitigate risks as there are built-in safety measures/controls rules to overcome the problems caused by design deficiency, wrong-material-choice, and more.

Until now, the usage and usability factors of construction operation building information exchange (COBie) datasheet has remained largely overlooked. This oversight may be the potential factor in the lower adoption rates as well as effective utilization of COBie datasheet in the architectural, engineering and construction – facilities management industry. Cobie Data drops as a concept has difficulty in adoption pertaining to lengthy process of data capturing with high reliance on manual inputs. Finding from this study will enhance the usability aspects of COBie by looking at the entire process of data assembling in conjuncture with design development and using it to understand the project changes. The paper aims to discuss these issues.

The study is aimed at solving a practical issue in handling COBie datasheets. The study uses iterative steps from design thinking and software development process (SDP) for development of the system. The iterative approach from design thinking helped to understand the problem scenarios, development of rule sets and analysis of various options to tackle this issue. SDP was used for the development and validation of the COBieEvaluator prototype.

Despite the information exchange standards such as COBie is available for adoption for quite some time, its perceived value in the whole chain is less described. Various concepts such as preparing COBie sheets from beginning of project are discussed but hardly adopted due to lengthy process. The study helps in substantiating the need for a continuous data capture and showcase how this continuous data capture can help in tracking various design and equipment changes inside a project, using COBieEvaluator. A comparative view over the data helps in giving fruitful information about the project. The system also verify the quality of data inside the COBie datasheet by not only looking at the cell value inputs but also looking at the entire information linkage and finding the gaps.

COBie has mostly being analyzed as an output and its benefits. However, some important aspects of COBie datasheet such as the process of capturing and verifying it, and understanding the meaning of the changes during incremental building of COBie datasheet, is largely overlooked. This study use the concept behind COBie data drops and devise a system to help track effect of project design changes on COBie datasheet. It also highlights the importance of not looking COBie datasheets only as a FM handover requirement, but a source of information which can help various stakeholders to get useful information about the project development. The study propose a comparative dimension over the COBie sheet to get useful insight over the project development.

Despite smart construction technology's great potential to improve the productivity of the architectural, engineering and construction (AEC) industry, the implementation of smart construction technology has failed to achieve the expected benefits due to the negative usage behaviors of construction enterprise employees. This study aims to identify the determinants and their configuration effects on the smart construction technology usage behavior (SCTUB) based on the Technology-Organization-Environment (TOE) framework. This study then verifies the practical paths to improve the employee's SCTUB from the configuration perspective.

A mixed-method approach involving survey and qualitative comparative analysis (QCA) is conducted in this study. Based on the detailed literature review and semi-structured interview, this study identifies the factors and proposes the TOE framework to determine the configuration conditions affecting employee's SCTUB and verify practical paths to promote this user behavior.

The TOE framework's technical, organizational and environmental elements are interdependent. The emergence of a high SCTUB is not determined by a single determinant but by configuration conditions. Four equifinal conditions (e.g. organization-technology type, technology-organization type, environment type and organization-technology balanced type) are verified to promote construction enterprise employee's SCTUB.

The four verified configuration conditions could guide construction enterprises to formulate complementary strategies for promoting the construction enterprises' employees to implement smart construction technology and achieve the enterprise's digital transformation.

The inter-dependence of the three-dimension factors, namely technical, organizational and environmental elements are explored to enrich the literature on the TOE framework. Meanwhile, the configuration effects of these factors on usage behavior are identified, expanding the literature on the information technology acceptance model.

The purpose of this study is to present the importance of integrating common features between the Green Mark Scheme (GMS) and the Buildable Design Appraisal System (BDAS) requirements in building envelopes.

The study presents the common features that influence both the GM score of the building envelope and the buildability score of the wall system. A case study is developed to show the effects of varying the value of a representative common feature in the GM score and the buildability score.

The study finds that lengths of window and wall, and wall materials are the common features that can influence the GM score of the building envelope and the buildability score of the wall system. The case study suggested that the window‐to‐wall ratio (WWR), which is the representative common feature, shows negative relationship with the GM score of the building envelope and positive relationship with the buildability score of the wall system.

The results show that varying the WWR influences the GM score of the building envelope more strongly than the buildability score of the wall system. This seems to imply that building professionals when determining the WWR may have to concern themselves with the GM score of the building envelope more as compared to the buildability score of the wall system.

The study suggests that integrating the common features between GMS and BDAS requirements with other relevant factors such as cost, social and environmental impacts of design can help to save workload, time and budget, as well as facilitate the delivery of more reliable design, planning and management from a practical viewpoint.

Because BIM adoption is still afflicted by various types of hurdles, a complete BIM implementation model is required to provide the necessary methods for driving BIM adoption. As a result, this study looked into the parts of the BIM implementation model that had the most impact on increasing the percentage of BIM adoption in South Africa.

This study developed a four-wheel model of BIM implementation based on implementation process theory, which includes BIM inspiration, BIM capacity development, BIM use and BIM commitment. To assess BIM capacity development, two sub-constructs (BIM learning process and BIM learning methodologies) were used. Two sub-constructs were used to assess BIM utilisation (efficient BIM application and effective BIM application). The sub-constructs employed to quantify BIM motivation were organisational competitiveness, societal conformity and contractual obligations. Incentives, investments and obligations were used to assess BIM commitment. The model was validated using four assumptions and maximum likelihood estimation – structural equation modelling (MLE-SEM).

The MLE-SEM results demonstrated unequivocally that all of the constructions are critical components of the BIM deployment paradigm in the South African construction industry. BIM motivation, as characterised by organisational competitiveness and social compliance, has the greatest impact. The findings on BIM motivation also revealed that the desire for technological sophistication, competitiveness and social acceptance by clients are encouraging construction organisations and professionals to embrace BIM adoption.

This study's findings have contributed to the increasing body of literature on BIM deployment. The study has significant implications for achieving BIM implementation in underdeveloped nations where BIM deployment is either non-existent or in its early stages. The theoretical component of the study serves as the foundation for further analysis of BIM deployment.

This research is important for identifying BIM goals, developing a BIM implementation framework, allocating resources for BIM implementation and defining key performance indicators for BIM implementation. The BIM implementation aspects outlined in this study will be effective in lowering BIM adoption hurdles.

This study makes a unique contribution to BIM research by providing theoretical and empirical analysis into the elements of the BIM implementation model in a developing country. The study offers an excellent opportunity to further our understanding of BIM application in underdeveloped nations.

The purpose of this paper is to propose and test a framework to foster safe work behaviour among workers on construction sites.

The proposed framework identifies two main reasons for unsafe behaviours: “don't know how”, and “don't care”. Technical and safety training is proposed to overcome the former problem, while for the latter it is proposed that organisations systematically apply operant conditioning techniques to promote safety, using organisational behaviour modification. A postal survey of contractors in Singapore was conducted to test the framework. The four tools of operant conditioning theory (positive reinforcements, negative reinforcements, extinction, and punishments) were evaluated.

Close and strict supervision, sending workers for safety and health training, and imposing fines are found to be most effective methods. Positive reinforcements (both monetary and non‐monetary) have also been found to be effective, while extinction did not receive much support. Other methods that may foster safe work behaviours are also discussed.

Safety on site could be enhanced via training and application of operant conditioning theory.

Building information modelling (BIM) has had a considerable impact on the socio-technical aspects of construction organisations. Culture has been considered an essential element in BIM practice. Hence, this paper aims to explore existing research relates to culture in the BIM context.

A systematic literature review (SLR) was conducted based on the PRISMA guidelines using 104 articles published between 2011 and 2020 and directed with a descriptive and content analysis.

The SLR results give evidence that culture in the BIM context is still an under-researched topic. Culture has been considered as both a dependent and independent factor in the BIM domain. Organisational BIM culture is a collection of fundamental beliefs established in a BIM using organisation and passed to new employees with the use of BIM. BIM using organisations are have either weak or strong BIM cultures. Proper analysis and understanding of the BIM culture of different organisations are necessary to realise the strategies of transformation from a weak BIM culture to a strong BIM culture.

To the best of the author's knowledge, this is the first SLR in BIM research that investigates the role of culture in the BIM setting. This study contributed to the existing body of knowledge by proposing a conceptual framework to understand and change a weak BIM culture of an organisation to a strong, matured BIM culture. This SLR serves as a future research basis in BIM-triggered culture.
