Material Reuse

Purpose The purpose of this paper is to explore the intersection of building material reuse and heritage value, and raises questions about how “preservation” has traditionally been defined and conceptualized. With a grounding in the realities of global climate change, the paper argues for further research on the topic and for the active engagement of the preservation field in reuse efforts. Design/methodology/approach After a review of existing literature, this study takes a descriptive and conceptual approach to explore the heritage values generated through material reuse. Findings This paper finds that processes of material reuse are richly embedded with heritage value and offer a conceptual challenge to established modes of heritage practice. Practical implications The findings of this paper suggest that heritage practitioners should actively engage with material reuse efforts to better understand the heritage values generated from such processes. Areas of future research and collaboration are identified. Originality/value Despite their intrinsic interaction with aged and existing infrastructure, there has been limited engagement in the heritage and preservation field with the topics of deconstruction, building material reuse, or construction and demolition waste practices more generally. This paper thus provides descriptive research on a topic that has been unevenly explored.

Purpose The purpose of this paper is twofold: first, to understand data management challenges in e-maintenance systems from a holistically viewpoint through summarizing the earlier scattered research in the field, and second, to present a conceptual approach for addressing these challenges in practice. Design/methodology/approach The study is realized as a combination of a literature review and by the means of analyzing the practices on an industry leader in manufacturing and maintenance services. Findings This research provides a general understanding over data management challenges in e-maintenance and summarizes their associated proposed solutions. In addition, this paper lists and exemplifies different types and sources of data which can be collected in e-maintenance, across different organizational levels. Analyzing the data management practices of an e-maintenance industry leader provides a conceptual approach to address identified challenges in practice. Research limitations/implications Since this paper is based on studying the practices of a single company, it might be limited to generalize the results. Future research topics can focus on each of mentioned data management challenges and also validate the applicability of presented model in other companies and industries. Practical implications Understanding the e-maintenance-related challenges helps maintenance managers and other involved stakeholders in e-maintenance systems to better solve the challenges. Originality/value The so-far literature on e-maintenance has been studied with narrow focus to data and data management in e-maintenance appears as one of the less studied topics in the literature. This research paper contributes to e-maintenance by highlighting the deficiencies of the discussion surrounding the perspectives of data management in e-maintenance by studying all common data management challenges and listing different types of data which need to be acquired in e-maintenance systems.

This article provides a picture of the latest developments in providing BIM-based tools for construction and demolition waste (CDW) management. The coverage and breadth of the literature on offering BIM-based tools and technologies for dealing with CDW throughout the whole life cycle of construction are investigated, and gaps are identified. Findings reveal that, although various BIM-based technologies are closely associated with CDW, much of the existing research on this area has focused on the design and construction phase; indeed, the problem of CDW in post-construction stages has received scant attention. Besides, the now available tools and technologies are lacking in cross-phase insights into project waste aspects and are weak in theoretical rigor. This article contributes to the field by identifying the intellectual deficiencies in offering BIM-based tools and technologies when dealing with CDW. So, too, it points to major priorities for future research on the topic. For practitioners, the study provides a point of reference and raises awareness in the field about the most advanced available BIM-based technologies for dealing with CDW problems.

PurposeThe 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.Design/methodology/approachDesktop 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.FindingsR&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.Originality/valueThe 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.

Purpose The purpose of this paper is to investigate the potential use of construction and demolition waste materials (C&DWM) as an alternative for natural fine aggregates (NFA), in view to solve the disposal problems caused due to landfills. In addition, to evaluate its suitability as a sustainable material, mechanical and durability properties have been performed on different proportions of concrete blending and the results recorded were compared with the reference concrete values. Design/methodology/approach In this research, the NFA were replaced at the proportion of 25%, 50%, 75% and 100% of C&DWM with a constant slump range of 130 mm–150 mm. This parameter will assess the consistency of the fresh concrete during transportation process. The characteristics of the end product was evaluated through various tests conducted on hardened concrete samples, namely, compressive strength, flexural strength, depth of penetration of water under pressure, rapid chloride penetration test, carbonation test and ultrasonic pulse velocity (UPV) test. All results recorded were compared with the reference concrete values. Findings The results demonstrated that the use of C&DWM in concrete portrayed prospective characteristics that could eventually change the concept of sustainable concrete. It was noted that the compressive and flexural strength decreased with the addition of C&DWM, but nevertheless, a continuous increase in strength was observed with an increase in curing period. Moreover, the increase in rapid chloride penetration and decrease in UPV over time period suggested that the concrete structure has improved in terms of compactness, thus giving rise to a less permeable concrete. The mechanical tests showed little discrepancies in the final results when compared to reference concrete. Therefore, it is opined that C&DWM can be used effectively in concrete. Originality/value This study explores the possible utilisation of C&DWM as a suitable surrogative materials in concrete in a practical perspective, where the slump parameter will be kept constant throughout the experimental process. Moreover, research on this method is very limited and is yet to be elaborated in-depth. This approach will encourage the use of C&DWM in the construction sector and in the same time minimise the disposal problems caused due to in landfills.

Waste from the construction sector poses huge challenges for sustainable waste management. This is not only due to the vast amount of waste produced in construction and demolition activities, but also due to pollutants potentially contained in these products. Subject to these conditions, waste management must ensure recovery of as many resources as possible, while making sure to keep material loops clean. This demanding task requires more knowledge about the existing building stock and an adaptation of current demolition processes. Innovative technologies, such as Building Information Modelling, or modern frameworks, such as Geographic Information Systems, offer a high potential to synoptically provide stock material information for future demolition activities for individual objects to be deconstructed as well as for whole cities as a basis for managing the anthropogenic stock and potential urban mining. Suitable methods of data collection allow for acquiring the desired input for the generation of building stock models enriched with demolition-related information. With the latter, selective deconstruction strategies as well as appropriate waste stream routing agendas can be planned and executed, thereby securing safety at work during the demolition process itself and a waste stream routing according to the waste hierarchy. This review article gives an overview of currently deployed building material assessment tools (data capture and visualisation), both a prerequisite for improved information on materials and geometry (and thereby mass/volume). In addition, this article describes workflows employable for the purpose of urban mining in end-of-life buildings, of which one holistic approach will be described in depth.

Purpose The purpose of this paper is to call for inclusion of alternative but complementary conceptual perspectives in entrepreneurial decision-making theory and practice. Design/methodology/approach A conceptual approach, drawing on two sets of theoretical perspectives relating to decision making of entrepreneurs, is adopted. Findings The paper presents a conceptual framework of entrepreneurial decision making utilising the intersection between a metacognitive model of the entrepreneurial mindset and the recognition-primed decision-making theory. The paper argues that the convergence of these theoretical viewpoints provides a selection of decision-making processes for entrepreneurs in an uncertain business environment. Practical implications Decision-making models and tools are available to entrepreneurs; however, the relevance and applicability are restrained by the complexity and uncertainty of business environments in which entrepreneurs operate. New and more inclusive conceptual perspectives are required to improve the accuracy of decision making. Originality/value The study offers a framework that integrates two diverse theoretical dimensions of entrepreneurial decision making. The findings of this study provide direction for practice and for future research on entrepreneurial decision making. The paper intends to encourage researchers to support a new combined theoretical approach and to help practitioners better understand the reasons for entrepreneurial decision failure.

Purpose – The purpose of this study is to review the existing typologies of buyer-supplier relationships (BSRs) in the literature, to critically assess their dimensions and underlying assumptions, and to propose a more complete BSR typology and future directions for BSR typology research. Design/methodology/approach – This study takes a conceptual approach in highlighting the limitations of existing BSR typologies and synthesizing their key typology-defining variables when proposing an alternative BSR typology. Findings – The proposed BSR typology is based on alternative behavioral assumptions: bounded rationality and choice-determinism, and uses relationalism, supplier dependence and buyer dependence as the typology-defining variables. This BSR typology captures four prominent BSR types in the extant literature (i.e. market/discrete relationship, captive-buyer/supplier-dominant relationship, captive-supplier/buyer-dominant relationship and strategic/bilateral partnership) and four new BSR types developed in this study (i.e. supplier-led collaboration, buyer-led collaboration, competitive/win–lose partnership, and free will/voluntary collaboration). Research limitations/implications – The performance implications of the new BSR types have yet to be empirically tested; however, empirical approaches for future research are discussed. Originality/value – As BSR typology research has been conducted over the years, a thorough review and systematic assessment of the extant research in terms of fundamental assumptions, typology-defining variables, overall progress and limitations becomes an important reflective task in guiding future research efforts toward the collective advancement in this line of inquiry. Departing from the existing literature, this study also uses more realistic BSR assumptions and a more complete set of typology-defining variables in developing an alternative BSR typology, arguably more complete and more theoretically sound than the previous BSR typologies in the literature.
