This study aims to identify senior citizens’ requirements related to “embedded retirement facilities (ERFs)”, which are small-scale, multi-functional and community-based care facilities for senior citizens in mainland China, and to discuss whether senior citizens’ perceptions are influenced by their backgrounds.

A questionnaire type of research was administrated to gain senior citizens’ rankings of services that should be provided by ERFs. Non-parametric statistical models were applied to analyse the collected data.

Results reveal that health care services for senior citizens are considered the most important. Requirements regarding rehabilitation and entertainment and daily life assistance are ranked second and third, respectively. Culture-related activities are the least important. Differences in the senior citizens’ background also influence their choices.

This research is based on a questionnaire survey completed in northeast China. Opinions from other areas of mainland China will be collected in the future study. Furthermore, the key items identified in this research, which was completed by participants from the built environment discipline, can be further elaborated by combining interdisciplinary feedback.

This study explores services that are supposedly provided by ERFs. Findings will provide useful perceptions from senior citizens and will enable decision makers to prioritise services for senior citizens.

Although senior citizens are the end users of ERFs, their needs are easily overlooked. This study calls attention to their needs from ERFs, and the results are likely to serve as references for stakeholders in building improved facilities.

ERFs have been provided in mainland China to cater to senior citizens’ needs since 2014. However, few studies have identified senior citizens’ requirements for provided services. The survey-based results of this work will serve as references for various stakeholders in making enhanced decisions.

Integrating sustainability into the value management (VM) process can provide a strategic platform for promoting and incorporating sustainable design and development during the lifespans of construction projects. The purpose of this paper is to investigate the strengths, weaknesses, opportunities and threats (SWOT) for integrating sustainability into the VM process in Hong Kong.

Following an extensive literature review, 45 attributes were identified and grouped into strength, weakness, opportunity and threat elements. A questionnaire survey based on these groupings was supported by semi-structured interviews with public sector clients, value managers and VM facilitators. They shared their experience and views on how to integrate sustainability into the VM exercises.

The triangulated results of the survey and interviews are presented in this paper. The ranking of the SWOT analysis results indicate that VM does provide opportunities for multidisciplinary professionals and stakeholders to focus on issues relating to society and the environment, which is considered a main strength. The major weakness of integration is the lack of well-trained staff and low levels of VM participant expertise in relation to the sustainable construction issue.

Current practices generally neglect integration of sustainability into the VM process due to cost and time constraints. There are ample strengths and opportunities recommended by this study for integrating sustainability into the VM process which are beneficial for the clients and contractors for achieving value for money and meeting sustainability targets.

There are immense opportunities for integrating sustainability into the VM process, including encouragement of the reduction, reuse and recycling of construction and demolition waste. However, threats presented by integration include the additional time and costs required for achieving sustainability targets.

Findings and recommendations provided in this paper should be helpful to decision makers including clients and VM facilitators for the successful integration of the sustainability concept into the VM process.

This study aims to investigate the dynamic influences of clustered barriers that hinder electronic procurement technology (EPT) implementation in construction procurement, using the neuro-fuzzy system.

A comprehensive literature review was conducted and 21 barriers to EPT implementation within construction projects were identified. Based on an expert survey, 121 datasets were gathered for this study. Using mean and normalization analysis for the datasets, 15 out of the 21 barriers were deemed to have critical influences in EPT barriers phenomenon. Subsequently, the critical barriers were classified into five groups: human-related; technological risk-related; government-related; industry growth-related; and financial-related. The relationships and influence patterns between the groups of barriers to EPT implementation were analyzed using the neuro-fuzzy system. Furthermore, sensitivity analysis was performed to examine the dynamic influence levels of the barriers within the hindrance level composition.

The results reveal that addressing one barrier group does not reduce the high levels of hindrances experienced in EPT implementation. However, addressing at least two barrier groups mostly tends to reduce the hindrance levels for EPT implementation. Further, this study revealed that addressing some barrier group pairings, such as technological risk-related and government-related barriers, while other barrier groups remained at a high level, still resulted in high levels of hindrances to EPT implementation in construction procurement.

This study provides insights for researchers to help them contribute to the development of theory with contemporary approaches based on the influence patterns of barrier interrelationships.

This study provides a model that would help practitioners and decision makers in construction procurement to understand and effectively determine the complex and dynamic influences of barrier groups to EPT uptake, for the development of suitable mitigation strategies.

This study provides novel insights into the complex influence patterns among grouped barriers concerning EPT adoption in the construction industry. Researchers and practitioners are equipped with knowledge on the influence patterns of barriers. This knowledge aids the development of effective strategies that mitigate the combined groups of barriers, and promote the wider implementation of EPT in the construction industry.

A reengineering philosophy for the construction industry has emerged, harvesting components of a production philosophy. The objective of construction process reengineering is to progressively develop an integrated project delivery process focusing on optimising process predictability and enhancing the value of the final product. This philosophy requires a holistic approach to reengineering, integrating the concepts of concurrent engineering, lean production and process redesign into the construction process. The objective of this paper provides an overview of construction process reengineering (CPR) through the examination of its origin, definition, concepts and application. A hospital project was used as a pilot case study to examine the application of the CPR concepts.

Hong Kong is running out of both reclamation sites and landfill space for the disposal of construction and demolition waste. This paper reports on the findings of a study, consisting of a questionnaire survey, interviews and work‐site visits, to compare the use of low‐waste building technologies in public housing and private residential projects in Hong Kong. The results show that large panel formwork and prefabricated building components are widely used in public housing projects in Hong Kong. Due to the difference of the design with public housing, the use of smaller aluminium panel formwork is more common in the private housing projects. The barriers for the adoption of low‐waste building technologies in the private sector are identified and discussed.

The purpose of this paper is to present site planning and design (SPD) relevant variables and items in practice for practitioners to better understand and implement SPD in green building projects.

The research methods include questionnaire survey and case studies in the context of China. A questionnaire survey was adopted to identify the importance of 13 variables and the corresponding 38 items in SPD of green residential buildings. Three green residential projects including one in Hong Kong and two in Mainland China were selected to investigate the SPD considerations in practice and to discuss the necessary improvement.

The results show that 12 out of the 13 variables of SPD in green buildings are involved in the three case projects to some extent, thereby underscore the importance of these variables. The potential improvement in real-life SPD of green buildings is also discussed such as adopting design-build and integrated project delivery methods and preserving and protecting cultural characteristics on site.

The research findings may serve as a reference for practitioners to better conduct SPD in green building projects.

The capacity of landfills will reach saturation in the 2020s. There are more than 50,000 buildings in Hong Kong over 30 years old and which may require extensive refurbishment under the Mandatory Building Scheme. Additionally, most new owners/tenants tend to renovate their premises before moving in. Hence, there is an urgent need in Hong Kong, to explore strategies and measures to enable the development of effective refurbishment and renovation (R&R) waste management for such projects. The objectives of this paper are to investigate the process of R&R for identifying the perceived barriers and thereby the strategies for minimisation and management of R&R waste in Hong Kong.

Desktop study, semi-structured interviews, site observations and document reviews were used as the data collection methods to achieve the objectives of this research. Considering the nature and characteristics of the industry structure, the snowball sampling process was deployed for data collection. Thematic analysis and content analysis were used for data analysis. Waste minimisation and management strategies for R&R projects were then discussed and developed by the research team and a focus group meeting was held to validate the research findings. Six strategies were then proposed to the government.

R&R projects contribute 10–20% of the construction and demolition waste. The barriers to recycling of R&R waste can be grouped into six major categories: (1) lack of sorting and storage spaces, (2) high cost, (3) insufficient government supporting policy, (4) complicated recycling processes, (5) immature recycling market and (6) insufficient public education. Also, six strategies are proposed in this study, which include (1) pre-refurbishment audit, (2) development of recycling market, (3) sea reclamation, (4) incineration, (5) government support and (6) education and research.

The strategies and measures proposed in this research could most adequately serve as reference for the government officials, building professionals and academic researchers. Such knowledge would make possible the development of effective strategies and measures for minimising and managing R&R waste.

Students find courses in research methods delivered by lectures, both difficult and boring. The purpose of this paper is to provide empirical research on another teaching and learning method, jigsaw method, to three groups of postgraduate students over three academic years.

The fifth topic of the course, qualitative research methods, was selected for implementation of the jigsaw class. The students completed a feedback questionnaire after classes to express their opinions and comments on the new method. Descriptive statistics and content analysis were used to test these data.

The students believed that the jigsaw method is an innovative teaching and learning activity and were generally satisfied with the process and the execution. They stated that participation was a valuable experience which enabled them to share knowledge with other classmates and gain a better understanding of the subject. Further improvements were also proposed by the students.

First, the analysis of the implementation of the jigsaw methods is based on student perceptions rather than objective measures of learning gains. Second, the classes for full-time postgraduate students are relatively small. Data were collected, therefore, over three academic years to provide enough valid responses for analysis.

The research may be regarded as pioneering in relation to jigsaw classes for teaching and learning research methods in postgraduate course. The findings provide confidence to architecture, engineering and construction (AEC) academics to incorporate jigsaw methods in their courses. The results of this study provide useful information for AEC lecturers assisting them to design their classes using jigsaw methods.

The purpose of this paper is to present a review of research developments on the ecosystem of driving forces for electronic procurement (e-procurement) on project procurement and to propose directions for future research for an effective adoption and sustained usage.

A systematic literature review was conducted in three phases to identify and examine literature. A total of 68 papers were retrieved and were thoroughly reviewed to identify the drivers for e-procurement.

A total of 61 drivers were identified and subsequently developed into a categorization framework for synthesized understanding which reveals existing interrelationships. Although literature has consensus on some selected drivers, few studies have identified drivers relating to sustainability. Gaps were identified from the existing literature and directions for future research were proposed.

Since this is a literature review, future research could conduct further investigations focusing on the research gaps identified. The framework developed presents a basis for further research to explore the drivers in various socio-economic environments.

This study provides valuable insights for improving the understanding of practitioners on the complex network of drivers for e-procurement. These findings stimulate discussions on benefits required for assessment in e-procurement adoption by practitioners.

This study provides the first comprehensive review of the drivers for e-procurement adoption in the construction industry, which was lacking in the existing body of knowledge.

This paper aims to investigate how unique features of built facilities would affect the application of greenhouse gas (GHG) emissions trading, and to explore what adaptive measures may be taken for emissions trading to be applied to the built environment. Emissions trading is a financial tool to encourage GHG emissions reduction in various industries. As the building sector is responsible for a large amount of GHG emissions, it is valuable to explore the application of emissions trading in built facilities.

The analysis is based on a comparative study reviewing the current emissions trading schemes (ETSs) in Australia, Japan and the UK covering the building industry, and to evaluate the approaches adopted by the schemes to tackle the problems related to buildings and facilities management.

The research findings reveal that the small energy savings of individual building units, the large variety of energy-saving technologies and the split incentives and diverse interests of building owners and tenants would be the barriers hindering the development of emissions trading. To overcome these barriers, an ETS should allow its participants to group individual energy savings, lower the complexity of monitoring and reporting approaches and allow owners and tenants to benefit from emissions trading.

This article provides a comprehensive overview of the current emissions trading practices in the built environment. Besides, it raises the attention and consciousness of policymakers to the need that building characteristics and facilities management should be taken into consideration when designing an ETS for the building sector.
