Abstract: Despite the recommendation of the international BIM standard ISO 19650, the current scope management process and practice for a BIM-enabled project need to be improved for the full benefits of the BIM adoption. Due to a lack of clarity in BIM-enabled project scope definition and roles and responsibilities for project key participants, unnecessary reworks and various change orders are occurred in the project execution phase. To minimise reworks and improve productivity, it is essential to understand the status of BIM-enabled project scope management practice. However, the current practice of scope management in a BIM-enabled project environment has been rarely studied. Thus, the research aims to identify the current scope management practice for BIM-enabled construction projects via interviews. It is revealed that the current scope definition process fails to provide clear roles and responsibilities for a BIM manager and a project manager separately. Additionally, the disconnection between the PIM and AIM causes ineffectiveness of utilising lessons learned for scope definition. The research findings will contribute to providing insights to improve the current scope management practice more suitable for a BIM-enabled project.

Abstract: The green accommodation sectors are increasingly committed to implementing environmental management practices while enhancing guests’ pro-environmental behaviour. However, it is not easy to change tourists’ behaviour as there are many factors influencing tourists’ participation in green management actions. This paper argues that a combination of multiple factors such as visitor characteristics or previous environmental experience needs to be examined to determine how these factors are differently associated with the type of pro-environmental behaviour. In particular, this study also investigates how environmentally responsible tourist markets can engage differently in different types of pro-environmental behaviour. Visitors staying at the green accommodation in Kangaroo Island, South Australia, were studied using self-administered questionnaires. The findings of this study confirmed the significant role of environmentally responsible travel experience as a strong predictor of two types of pro-environmental behaviour (e.g., energy-saving and recycling vs. eco-product consumption behaviour) and its moderating effects on the relationship between visitor characteristics and pro-environmental behaviours (PEBs). Furthermore, this environmental-responsibility-based segmentation approach provides green-oriented accommodation sectors with some managerial implications for improving green accommodation practices that can be operated on different principles for two different targeted markets based on their environmental responsibility. This study recommends that more in-depth investigations of other barriers or facilitators of pro-environmental behaviour are necessary to fully address this issue and to ultimately influence tourists’ responsible support for environmental management practices implemented by the green accommodation sector.

Abstract: While the Circular Economy in the built environment is often viewed in terms of recycling, more value can be obtained from buildings and physical components by their reuse, aided by stewardship and remanufacture, to ensure optimum performance capability. The use of cyber-physical information for online identification, examination and exchange of reusable components may improve their life-cycle management and circularity. To this end, a bi-directional data exchange system is established between physical building components and their virtual Building Information Modeling (BIM) counterparts, so that their life-cycle information—including history of ownership, maintenance record, technical specifications and physical condition—can be tracked, monitored and managed. The resultant prototype Cloud-based BIM platform is then adapted to support an ongoing product-service relationship between suppliers roviders and users/clients. A case study from a major new hospital, focusing upon an ex le of internal framed glazed systems, is presented for ”proof of concept” and to demonstrate the application of the proposed method. The result of the case study shows that, informed by the life-cycle data from the Cloud-BIM platform, a “lease with reuse” service option is able to deliver a lower total cost and less carbon intensity for each unit of frame-glazed module. This leads to a higher level of eco-efficiency, coupled with decreased consumption of material resources and reduced generation of waste. The research is expected to serve as a step forward in the era of Industry 4.0 and illuminate a more sophisticated way to manage building assets.

Abstract: The purpose of this study is to identify building information modelling (BIM) input data sets within a BIM-embedded housing refurbishment process and enable construction professionals to use BIM as an information management platform for housing refurbishment projects. A hypothetical case study using BIM tools for a housing refurbishment project is adopted to identify BIM input data sets to create a housing information model within a BIM system. Reliability of the research outcome is examined by conducting a comparative analysis between existing and simulated research outcomes. This research identifies essential BIM input data sets during the early design phase. The importance of a well-integrated housing information model containing accurate as-built condition, cost and thermal performance information is essential to use BIM for housing refurbishment. BIM can be feasible for housing refurbishment when an information-enriched housing information model is constructed. Furthermore, the capability of BIM that can enable key project stakeholders to determine the most affordable refurbishment solution among various alternatives is identified as BIM can provide reliable cost estimations and thermal performance of refurbishment alternatives at the early design stage. The examined refurbishment processes and input data sets are confined to the early design phases as BIM use for housing refurbishment is limited. This research will contribute to use BIM for housing refurbishment by providing essential BIM input data sets and BIM-embedded refurbishment processes. This research reveals primary housing information data sets and BIM-embedded refurbishment processes at the early design phase.

Abstract: Monocytes are the third most frequent type of leukocytes in humans, linking innate and adaptive immunity and are critical drivers in many inflammatory diseases. Based on the differential expression of surface antigens, three monocytic subpopulations have been suggested in humans and two in rats with varying inflammatory and phenotype characteristics. Potential intervention strategies that aim to manipulate these cells require an in-depth understanding of monocyte behavior under different conditions. However, monocytes are highly sensitive to their specific activation state and expression of surface markers, which can change during cell isolation and purification. Thus, there is an urgent need for an unbiased functional analysis of activation in monocyte subtypes, which is not affected by the isolation procedure. Here, we present a flow cytometry-based protocol for evaluating subset-specific activation and cytokine expression of circulating blood monocytes both in humans and rats using small whole blood s les (50 - 100 μL). In contrast to previously described monocyte isolation and flow cytometry visualization methods, the presented approach virtually leaves monocyte subsets in a resting state or fixes them in their current state and allows for an unbiased functional endpoint analysis without prior cell isolation. This protocol is a comprehensive tool for studying differential monocyte regulation in the inflammatory and allogeneic immune response in vitro and vivo .

Abstract: Although they offer major advantages, smart cities present unprecedented risks and challenges. There are abundant discrete studies on risks related to smart cities however, such risks have not been thoroughly understood to date. This paper is a systematic review that aims to identify the origin, trends, and categories of risks from previous studies on smart cities. This review includes 85 related articles published between 2000 and 2019. Through a thematic analysis, smart city risks were categorized into three main themes: organizational, social, and technological. The risks within the intersections of these themes were also grouped into (1) digital transformation, (2) socio-technical, and (3) corporate social responsibility. The results revealed that risk is a comparatively new topic in smart-city research and that little focus has been given to social risks. The findings indicated that studies from countries with a long history of smart cities tend to place greater emphasis on social risks. This study highlights the significance of smart city risks for researchers and practitioners, providing a solid direction for future smart-city research.

Abstract: The aim of this research is to examine if building information modelling (BIM) is feasible as an information management platform to determine a financially and environmentally affordable housing refurbishment solution based on the life cycle cost (LCC) and LCC calculation. A case study in conjunction with BIM simulation approach using BIM tools (Autodesk Revit and IES VE/IMPACT) was adopted to identify the feasibility of BIM for the simultaneous formulation of LCC and life cycle assessment in housing refurbishment. This research reveals that BIM is a suitable for the information management platform to enable construction professionals to consider trade-off relationship between LCC and life cycle assessment simultaneously, and determine the most financially and environmentally affordable refurbishment solution. The interoperability issues in data exchange among different BIM tools and unstandardized BIM object libraries with incomplete data sets of construction materials are recognised as the major shortcomings in a BIM system. Essential remedial actions to overcome the shortcomings in the current BIM tools are identified. Actual housing information and various refurbishment materials for the BIM simulation are limited. This research contributes to supporting construction professionals to prepare practical BIM adoption for the integration of the LCC and life cycle assessment that can significantly improve early decision-makings on sustainable housing refurbishment. This research will contribute to providing proper remedial actions to overcome the shortcomings in the current BIM tools, and insights for construction professionals to understand the implication of BIM-embedded housing refurbishment.

Abstract: Despite the advancements in digital technologies, the current building design examination practice is 2D and paper-based, and a large number of 2D plans and drawings need to be collated and interpreted to examine if the proposed designs comply with building regulations. Subsequently, it is prone to human errors that make sustainable and consistent design difficult. Although Building Information Modelling (BIM) is recognised as a means to transform the current practice into a more sustainable and productive practice, BIM has rarely been adopted in building design examination. This research aims to identify the reasons for the low uptake of BIM and to examine the feasibility of BIM for building design examination through a focus group interview and workshop. A lack of proper BIM training is identified as the most critical barrier to adopting BIM. Building design examiners indicate that BIM adoption requires consistent efforts with empirical errors, since the existing work processes are not flexible enough to embrace BIM instantly without proper BIM training. An average of three days can be saved by using BIM for a building regulations check. This research revealed that BIM is feasible for building regulation checking, and the low uptake is mainly caused by a lack of awareness of the BIM capabilities.

Abstract: The construction industry is currently struggling due to the ever-increasing complexity of a building and the highly fragmented nature of the construction industry. In response to the current problems, building information modelling (BIM) has been adopted to improve productivity and deliver a quality building to a client. The academia also has been striving to embed BIM education into the exiting curriculum to accommodate the needs of the construction industry. However, BIM is currently taught as a simple design tool rather than a methodology to improve productivity in construction projects. Although there have been various attempts to integrate BIM courses into the existing curriculum, a lack of research has been conducted regarding how BIM adoption and implementation strategy should be utilized for a BIM integrated curriculum. Thus, this chapter will provide insights for updating and developing BIM courses.
