The outbreak of Severe Acute Respiratory Syndrome (SARS) in Asia and North America has raised much concern from all angles and reflections on nowadays living environment that resulted in public health, especially the high−density urban residential complexes. The so−called community infection at Amoy Gardens apartment in Hong Kong was such a case that is worth further study. However, under the trends of globalization and sustainable development, SARS could be the first alert of unknown outbreak−type fatal epidemic to the coming biomedicine age.

Main findings of the investigation in Amoy Gardens by the Department of Health, Hong Kong, which has been mostly corroborated by World Health Organization (WHO), pointed that environmental factors played a major role in this outbreak. They are, in fact, related to community design, building design and facility management. In this respect, open building theory is conceived of ideas for solution. Three directions are discussed in this study: 1) “territorial depth” at urban tissue level and building level, 2) utility lines at building level and infill level, and 3) space layout by zoning at building level.

In conclusion, design principles for new buildings are suggested; (1) Creating territorial depths in urban tissue and building complex by hierarchical circulations so as to separate people's daily movement and reduce unnecessary human contacts. In addition, the deeper territory expands, the fewer the dwelling units will be preferred. (2) Planning unit space layout with envelope zone following fluid dynamics and solar control physics so as to avoid gaseous infection to people living in the neighborhood among multi−story buildings. (3) Constructing buildings with open−system interfaces between building level and infill level or between infill elements themselves, so that stopgap renovations could easily be done. (4) Separating service lines between building level and infill level. And locating maintenance shafts at accessible public space

Asset inventory is an essential part of any building asset management system and is needed by such functions as condition assessment and deterioration prediction. Previous studies in asset management systems have suggested the use of one of the many standard construction classification systems, such as UniFormat or MasterFormat, in achieving the goals of asset management. However, each classification system has its unique features, and it has been developed for different purposes and may not necessarily be directly adaptable to asset management. A proper classification system is thus needed to achieve the goals of building asset management effectively. Such a system must take into consideration the objectives and functions of asset management. Therefore, the purpose of this paper is to establish a unified work breakdown structure (WBS)-based framework for building asset inventory.

The WBS-based framework aims to cover the entire lifecycle of an asset so as to provide the unified classification system for asset inventory. The proposed framework is developed based on appropriate building standards. Also, comprehensive levels of details are included for space functions and locations for all assets in any type of building. Furthermore, this framework takes into consideration utilities in any kind of building project. As such, the WBS-based framework proposed in this research endeavor provides the basis for effective asset management. An educational building case study is presented and discussed to demonstrate the effectiveness of the proposed framework for asset management.

The unified WBS-based framework for building asset management effectively classifies asset inventories and facilitates decision-making in asset management during the lifecycle of an asset.

This research synthesizes a unified WBS-based framework for building asset management, which allows for a more effective lifecycle building asset management.

The purpose of this paper is to examine the level of theory building in public procurement by reviewing and classifying manuscripts published in the Journal of Public Procurement (JoPP) from 2001 to 2016.

The articles are divided into four important periods: discovery, agenda setting, embracing and expansion and consolidation. The articles are classified according to a hierarchical level of theory building composed of six levels: rapporteurs, reporters, testers, qualifiers, builders and expanders.

Key findings indicate that public procurement, in light of JoPP publications from 2001 to 2016, is at the tester level. There is also increase in the classification of articles with high level of theoretical contribution over time.

Improving indoor environmental conditions and, thus, health standards will have a direct impact on the performance of the employees and, thus, organisations and on the wealth of the community. The indoor air quality, lighting, ergonomics, acoustics and health complaints scales are widely used to determine building performance levels. The research model was tested using responses from 362 employees in 25 diverse hospitals. The results indicate that building comfort level assessments play a critical role in influencing the health complaints and building general sufficiency level judgements of the employees. These judgements differ from each other for the hospital groups classified according to the ownership criteria. This study will support a better evaluation of development policies of workplace environmental conditions by managers.

The purpose of this paper is to elucidate best approaches for facility radon management in a resource-limited environment such as a public university. Radon exposures are believed to be a risk factor for lung cancer. However, the degree to which typical indoor radon levels within settings such as the university campus contribute to lung cancer risk is controversial. The authors sought to develop a risk-balancing approach to safe and cost-efficient facility radon management.

The authors collected pilot monitoring data to determine radon activity levels at a large public university within a projected high-radon region of the southeastern USA, then reviewed scientific literature, trade literature and regulatory guidance to determine radon risk knowledge and best practices for mitigation. From this body of data and information, the authors determined the safest and most resource-effective means for campus radon management.

The developed program for comprehensive radon management included guidance on building selection for most effective use of monitoring, tiered response and mitigation strategies based on radon activity levels and faculty, staff and student education.

The radon management strategies might not be generalizable to facilities with usage patterns that differ from a public university, and should be extrapolated with caution.

This paper shows how building managers can address indoor radon in a manner that maximizes both safety and cost-efficiency.

This paper fulfills a need for evidence-based and prudent approaches to radon management for campuses with mixed residential, educational and occupational contexts and limited resources.

The purpose of this study is to look at what Urban Facilities Management (FM) and Green Leasing have in common and the degree to which they are ultimately reliant on one another. Whilst both are similar in terms of their placement in organizational management, Green Leasing is a building level concept whilst Urban FM is at the community level. The primary purpose of this paper is to show how the commonalities of both can strengthen one another and offer tangible possibilities to improve the sustainable credentials of urban development projects.

This study will be conducted with a mixed-methods approach. Firstly, a literature study will determine the commonalities between both concepts, and the degree to which they rely on one another to work effectively in projects. The second method will be a cross-sectional case study. Using existing cases that use both (either implicitly or explicitly), the study can demonstrate how these commonalities and reliabilities can offer tangible outputs to real work projects. These will then be combined in a case study to demonstrate many of these aspects in a real-world setting.

The finding demonstrates that there are commonalities between Green Leasing and Urban FM at all levels of organizational management and that the success of both requires holistic consideration of each other, as well as other aspects such as FM and citizen participation. The success and failure of projects are depending upon considering these aspects. By not considering the buildings and community levels as separation aspects, but more as different levels of the same project, multi-level considerations can contribute to the success of urban development projects.

The commonalities between Urban FM and Green Leasing are profound and do not just show the value of holistic thinking, but also the inclusion of other considerations such as FM to reduce project failure and long-term project viability. This can add value to the study of not just Urban FM and Green Leasing, but also FM more generally, architectural design and urban planning.

The need for capacity building of construction industries in developing countries cannot be over‐emphasised in order to ensure quality of services and products as well as the application of innovative ways for delivering construction services. Accordingly, using systems institutional paradigm approach as a conceptual premise, this paper aims to make the case for a fundamental turnaround for construction developmental approach in developing countries, that identify levels which should be considered as instrumental for capacity building of the construction industry in the Sub‐Saharan region, for example Malawi.

To ascertain a quad‐level framework which should be considered essential for capacity building of the construction industry, a questionnaire survey was employed. Data were elicited from prominent heads of sections from five stakeholders of the construction industry that operated in Malawi on the constructs for capacity building of a construction industry. Sixty completed questionnaires were received with a response rate of 90 per cent to the designed sample size.

The quad‐level framework for capacity development of a construction industry for developing countries was validated by an overall level of 77 per cent of agreement from key and prominent heads of sections of the five stakeholders of the construction industry. The rankings of the variables for capacity building for each level of the framework have provided the key foci and orientations of the industry for one of the Southern African countries of the Sub‐Saharan region.

The study forms the basis for further research; future research could be directed towards other developing countries to further enrich the industry on the dynamics of capacity building of construction industries in developing countries.

This paper is the first to critically examine the antecedents and invoke a quad‐level framework for capacity development of construction industries.

Open Building and IFD (Industrial Flexible Demountable) building are philosophies that aim to create high quality buildings with increased flexibility and better environmental characteristics. However, a successful adoption of IFD principles has not yet occurred because of concerns for the types of connections that are needed between building components. Therefore, this paper describes PhD research at the University of Twente that has the objective of designing a typology of flexible interfaces for IFD building that can be widely applied in the construction industry and aims to standardize connections, at the various levels of technical composition of a building, to create compatibility between building products from different suppliers. Such a typology of interfaces will increase the re-use and recycling of building parts, resulting in the increased sustainability of the building process. Furthermore, it will help accelerate the industrialization of the housing industry and mass customization of housing. A preliminary case study, in which a sustainable, flexible bathroom is designed, illustrates the various types of interfaces that can be applied, based on existing research. The paper illustrates the importance of interfaces, and aims to increase environmental benefits of buildings (less construction waste), improve the social aspects (higher user satisfaction in buildings) and achieve economical advantages (lower overall costs) by designing new interfaces.

Maintenance management of health care facilities is one of the more complex subjects in the field of maintenance. The performance of hospital buildings is affected by numerous factors, including quality of hospital maintenance, actual occupancy vs standard occupancy, age of buildings, surrounding infrastructures, etc. The purpose of this research was to quantify the effects of users, building parameters and systems on the performance and maintenance of hospital buildings. The following factors were investigated: overall performance of the building; age of the building; level of building occupancy; and extent of labor outsourcing. The effects of the above parameters and variables were examined and quantified, employing coefficients and diagrams, using analytical and statistical analysis. The coefficients and diagrams developed were integrated into four key performance indicators for hospital buildings. The model was tested on six case studies, one of which is presented here.

This paper aims to investigate the theoretical and practical links between digital twin (DT) application in heritage facilities management (HFM) from a life cycle management perspective and to signpost the future development directions of DT in HFM.

This state-of-the-art review was conducted using a systematic literature review method. Inclusive and exclusive criteria were identified and used to retrieve relevant literature from renowned literature databases. Shortlisted publications were analysed using the VOSviewer software and then critically reviewed to reveal the status quo of research in the subject area.

The review results show that DT has been mainly adopted to support decision-making on conservation approach and method selection, performance monitoring and prediction, maintenance strategies design and development, and energy evaluation and management. Although many researchers attempted to develop DT models for part of a heritage building at component or system level and test the models using real-life cases, their works were constrained by availability of empirical data. Furthermore, data capture approaches, data acquisition methods and modelling with multi-source data are found to be the existing challenges of DT application in HFM.

In a broader sense, this study contributes to the field of engineering, construction and architectural management by providing an overview of how DT has been applied to support management activities throughout the building life cycle. For the HFM practice, a DT-cum-heritage building information modelling (HBIM) framework was developed to illustrate how DT can be integrated with HBIM to facilitate future DT application in HFM. The overall implication of this study is that it reveals the potential of heritage DT in facilitating HFM in the urban development context.
