Building information modelling (BIM) is a paradigm shift in the architectural, engineering and construction industries which transforms processes to achieve greater efficiency and effectiveness. The purpose of this paper is to highlight the implementation of BIM in Hong Kong and the USA and recommend strategies for BIM implementation in Hong Kong.

A literature review of BIM initiatives taken in Hong Kong and the USA was conducted including the government policy, guidelines, standards and implementation status. Findings from the literature review were complemented with insights obtained through focused interviews of experts in the field for arriving at recommendations based on the research. The principal investigator of this research also participated in the establishment of a BIM professional institute as one of the founding board members.

As a result of studies performed for this paper, guidelines are proposed for BIM implementation in Hong Kong. The role of government in implementing BIM in different phases of a project lifecycle is also highlighted.

The research is limited mainly to the initiatives of BIM taken by the public sector (government). The roles of other stakeholders are not specifically studied. Results from this study should be considered in the context of a qualitative research methodology adopted and the limited number of responses obtained for arriving at the findings of this paper.

Results from this study can be used as guidelines for the implementation of BIM elsewhere and this implementation can be compared with other countries.

This paper highlights the best practices of BIM implementation, which is useful for the effective and efficient implementation of BIM in Hong Kong.

This research paper is a literature review of the existing building retrofitting process. It proposes studying the functional, technical, and organizational issues of the green retrofit process. The purpose of this paper is to expand the domain of design framework for retrofitting existing buildings.

The paper provides a review of the model-based design process from enrollment to evaluation stages representing the green retrofitting process in selected publications. The paper opted to review the Green Retrofit Design (GRD) process model for achieving a systematic design model of GRD development in the future.

Functional and maintenance issues are mainly for new buildings, also in the field for renovation and demolishing. Publications also show that environmental, social, and technical issues are often examined separately in the decision process of GRD. Papers in the facility management scale would concentrate more on organization/legal issues. Publications with questionnaire design are devoted to the usage on life-cycle assessment on existing building, but not yet on the stakeholder management and design process and related issues.

The achievement of the study is to provide a new framework of design approach that is significant to the theoretical research, education, communication, and practical works in terms of GRD development.

The paper not only achieves a specific sequence of practical approaches, including awareness of problems, conceptual development, and design embodiment, to meet design objectives, but also conforms to academic practice-based research of creative design taking on GRD practice.

This paper aims to identify the challenges of Hong Kong and overseas developers in project management when undertaking real estate projects in China, and then focuses on how to mitigate and solve the problems. The proposed solution is about a concept of using the IT tool “web‐based construction project management system” (WPMS) to help assuring projects success in China. The study reported in this paper focuses on how to implement WPMS to manage construction projects in China considering the overall situation, limitations and Chinese culture.

Case studies and interviews were adopted to identify the main reasons why experienced Hong Kong developers have apparently been outperformed by the capital‐deprived local developers in China. SWOT was applied to analyse project failure factors. Afterwards, 49 web‐based construction project management software systems were reviewed to identify their features, their client expectations, the technology propagation modes, and the most emphasized functions in the construction stage. An in‐depth case study was adopted to test the hypothesis that web‐based construction project system could help Hong Kong developers to properly manage their projects in China.

Cooperation and coordination difficulties among participants caused by long geographical project distance and remote management control were identified to be the main causes of project failure. Web‐based construction project management system was proved to be efficient and effective in cross region project coordination and monitoring. Since property development business is a continuing and non‐one‐off activity, the investment of a tailor made WPMS is really good value for money. Concerning the low readiness of business partners in China, an encouraging pattern with more self‐incentives should be considered for achieving a win‐win‐win situation as an essential tactic as proposed in this paper.

How to evaluate the benefit of using WPMS in quantitative method remains a challenge. Future research could compare the project with WPMS and without WPMS.

The case study of the application of a tailor‐made web‐based project management system (named ICPMS) by one of the major developers in Hong Kong has demonstrated that the headquarters in Hong Kong is able to get timely first hand project information, facilitating timely decisions and ensuring project success. Thus, the adoption of WPMS is a worthwhile investment for overseas developers undertaking real estate development projects in China.

This paper puts forward the concept of overseas developers using WPMS to help assure project success in China. Chinese culture and other limitation factors were considered for the first time in WPMS implementation in the construction industry. How to make the implementation of WPMS to successfully overcome such barriers is illustrated based on this empirical study.

Successful implementation of infrastructure projects has been a controversial issue in recent years, particularly in developing countries. This study aims to propose a decision support system (DSS) for the evaluation and prediction of project success while considering sustainability criteria.

To predict sustainable success factor, the study first developed its sustainable success factors and sustainable success criteria. These then formed a decision table. A rough set theory (RST) was then implemented for rules generation. The decision table was used as the input for the rough set, which returned a set of rules as the output. The generated rulesets were then filtered in fuzzy inference system (FIS), before serving as the basis for the DSS. The developed prediction tool was tested and validated by applying data from a real infrastructure project.

The results show that the developed rough set fuzzy method has strong ability in evaluation and prediction of the project success. Hence, the efficacy of the DSS is greatly related to the rule-based system, which applies RST to generate the rules and the result of the FIS was found to be valid via running a case study.

Use of DSS for predicting the sustainable success of the construction projects is gaining progressive interest. Integration of RST and FIS has also been advocated by the seminal literature in terms of developing robust rulesets for impeccable prediction. However, there is no preceding study adopting this integration for predicting project success from the sustainability perspective. The developed system in this study can serve as a tool to assist the decision-makers to dynamically evaluate and predict the success of their own projects based on different sustainability criteria throughout the project life cycle.

The construction industry plays a significant role to the economy of Hong Kong not only in terms of output but also the employment. The sector, however, has been severely hit by the economic downturn in recent years resulting in serious unemployment. Employment planning becomes one of the critical aspects for the recovery of the economy. The main objective of this paper is to establish a labour demand model for the Hong Kong construction industry. The unique characteristics and the current conditions of the construction labour market are reviewed. Regression analysis based on 123 construction projects was used to compute the relationship between expenditure and site workers employed. The best predictor of average labour demand of construction projects in Hong Kong is found to be DL = 463 C 0.934, where DL is the actual labour demand in man‐days, C is the final cost of contract in millions. The labour demand‐cost relationship can be applied as a manpower forecasting model to estimate the total labour required for a given type of project. The developed model enables a more reliable and accurate planning of manpower requirements in the construction industry.

Wonders whether companies actually have employees best interests at heart across physical, mental and spiritual spheres. Posits that most organizations ignore their workforce – not even, in many cases, describing workers as assets! Describes many studies to back up this claim in theis work based on the 2002 Employment Research Unit Annual Conference, in Cardiff, Wales.

This research aims to explore the perspectives of the key actors in the New Zealand construction industry towards BIM adoption. Specifically, four themes are examined, including what BIM is; BIM knowledge and understanding; benefits of BIM adoption; and challenges/barriers to BIM adoption.

A qualitative approach using 21 semi-structured interviews with industry experts was adopted.

The results raise a question concerning whether the New Zealand construction industry needs a unique definition of BIM to achieve a clear and consistent understanding amongst construction practitioners. It was found out that most of the construction practitioners in New Zealand are not well aware of BIM, especially the contractors, QSs, supply chain companies and the SMEs. Fourteen potential benefits and ten barriers/challenges to BIM adoption were identified. Individually, time-saving was considered as the most benefit of BIM adoption while BIM understanding was suggested as the most significant barrier by all the interviewees.

The research provides valuable insights into BIM understanding as well as recommendations regarding BIM adoption in New Zealand. The results could be considered baseline information for the companies and government to have effective strategies towards BIM adoption. Furthermore, it confirms that characteristics such as benefits and barriers to BIM adoption amongst different countries could be similar. Therefore, it could be useful to analyse the studies, strategies and practices of the pioneer countries in BIM adoption for the implementation.

The purpose of this paper is to propose a research model to identify the key determinants and examine their impact towards online pro-brand and anti-brand community citizenship behaviours (CCBs).

A survey based on the research model is used to collect empirical data from 260 and 200 members of online pro-brand communities (OBCs) and online anti-brand communities (OABCs), respectively. A two-stage approach employing fuzzy-set qualitative comparative analysis and artificial neural network (ANN) is first applied to uncover new observations.

Moral identity and positive brand emotion (BE) are the two most influential factors driving both online pro-brand and anti-brand CCBs. A higher level of internalisation might be required to exhibit online anti-brand CCB as opposed to online pro-brand CCB. This contradicts the current understanding that anti-brand behaviours are less morally restricted given the virtuality and anonymity of online communities. OABC members may need to better justify themselves internally to overcome positive BE when exercising anti-brand action. Also, brand identification, brand dis-identification and BE would be used to identify two types of OABC members.

The effect of motives other than pro-social remains unclear on online pro-brand and anti-brand CCBs.

This is the first paper to develop two new dimensions which provide a more complete definition of CCB. Also, some new observations are uncovered by comparing the effect of different key determinants on online pro-brand CCB against that of online anti-brand CCB. The research model can be used to define and improve member (or brand) engagement which would enhance the management of OBCs and OABCs.

Learners with autism require specialized education and supports to ensure acquisition and mastery of various communication skills. This is particularly true for individuals whose disability significantly impacts their language development. Without functional communication, these individuals often engage in severe behavior, have reduced self-determination, and experience diminished quality of life. Accordingly, researchers in special education and related fields have sought ways to improve the communication skills of learners with autism who need specialized language and communication interventions. Although the Picture Exchange Communication System (PECS) is well-established in the empirical literature and has helped countless individuals learn to communicate, the method known as facilitated communication (FC; which also is being called “supported typing” and “rapid prompting method”) has become increasingly popular in recent years. Few methods in special education have been as thoroughly discredited as FC and perhaps none are as dangerous. This chapter contrasts the thoroughly debunked FC and its pseudoscientific characteristics with those underpinning PECS. A brief historical account of each method is provided along with key scientific and pseudoscientific features that distinguish science from pseudoscience. Ultimately, our intent is to further clarify how FC is not an augmentative or alternative communication method and why PECS is.
