The purpose of this paper is to discuss the roadmapping methodology and its application to concrete prefabricated housing in Australia.

The paper describes the concrete and housing industries of Australia collaboration in a project to develop a technology and innovation roadmap that will advance the concrete industry's supply chain capabilities by identifying and mapping innovation necessary for prefabricated concrete house construction. The roadmap lays out what is necessary for an off‐site systems‐based approach to housing construction in Australia. The systems‐based approach to prefabricated concrete products is a relatively new and developing extension of the concrete industry supply chain in Australia. New manufacturing technologies and innovations, which are emerging locally and from overseas, make these potential extensions possible. For the long‐term sustainability of the concrete industry, it is critical that it better understands how to adopt cooperative innovations in prefabrication to realise these benefits in the housing industry and advance Australia's competitiveness. The first phase of the mapping involved the development of an industry‐maturity model that determined the current state of the industry, and plotted this against the desired route for the future. Numerous industry‐based workshops and interviews gathered the views of the industry towards existing concrete housing systems, and where their main difficulties are in relation to adoption. Using these data, a technology roadmap is developed, together with three options on how these might be realised using the roadmap. The options offered through the roadmapping process form the basis for ongoing experimental trials of concrete houses in the major cities of Australia.

The system‐based approach to prefabrication is seen as innovative and the industry needs to understand how to adopt cooperative innovations in prefabrication in order to be competitive.

The paper offers insights into the technology roadmapping process in Australia, offering an exciting prospect for moving the industry into a new model of delivery.

The purpose of this paper is to introduce a Central-European perspective into the international discussion of the participatory place-making. The research focuses on the renewal of the large prefabricated housing estates, dominant type of urban housing in the area where after the privatisation process resident-owners own only a so-called floating plot under their block. In total, 80 per cent of the land of the whole neighbourhood remains public. The question is how participatory place-making works in this specific urban, social and cultural situation?

By introducing the topic from a theoretical point of view, the study is based on research conducted in Budapest’s Újpalota Housing Estate. Fieldwork, project analysis and interviews uncover the complexity of this Hungarian case where appropriation of residents, municipality and European social regeneration projects are simultaneously present with different types of participatory methods.

The majority of real changes in Újpalota – as well as in housing estates of post-Communist countries in general – are led by individual or common appropriation that sometimes becomes convincing participation. This informal transformation of the built or natural environment can create a small sense of place everywhere. At the same time, it can work against the architectural and urban character of a neighbourhood or a building, rendering a feeling of disorder.

The paper based on this Hungarian case shows that the real culture of participatory place-making is still missing in post-Communist context, and despite some good examples, the majority of people are inactive, waiting for changes to be made by leaders.

The development of prefabricated buildings has become one of the primary solutions to transform the traditional construction industry around the world. Incentive policy is one of the important driving factors for the development of prefabricated building. The policy system in the field of prefabricated buildings needs to be improved urgently. However, there is still a dearth of research on how incentive policies exert impact on the development of prefabricated buildings. This paper aims to reveal the impact mechanisms of different types of policies on the development system of prefabricated buildings.

This study categorizes prefabricated building policies, constructs a system dynamics model of prefabricated building policies and conducts scenario simulations to examine the impact and sensitivity of different types of policies on the development system of prefabricated buildings.

The results show that compulsory policies play a greater role in the early stage of prefabricated building development and need to be withdrawn at the right time. Preferential and encouraging policies play an incentive role in the middle and later stages of prefabricated building development. Encouraging policies predominate in the later stage of prefabricated building development. Based on the research results, policy recommendations for prefabricated building development are put forward respectively from the government, developers and consumers.

The research results are expected to make up for the lack of clear policies paths in existing research and provide theoretical references for the formulation and optimization of future policies.

This study aims to examine how innovation can be accelerated within the New Zealand (NZ) building industry to improve the productivity and efficiency of the industry.

The study adopted a mixed philosophical approach combining interpretivism and post-positivism. Data for the study were obtained through a focus group of 50 practitioners that were selected using a stratified sampling procedure. All focus group data were audio-recorded, notes of the discussions were taken and then transcribed, de-identified and managed using NVivo software. Data analysis was undertaken using thematic analysis and inductive reasoning consistent with interpretative phenomenological analysis.

The study findings revealed that the industry could benefit from the adoption of new and emerging technologies to improve its performance, especially its productivity and efficiency. Key drivers for the adoption of innovative practices included the adaptation of “local best practices” from case studies that would consist of stories of successful innovations that could foster confidence in future innovation. It was also identified that Government and industry should nurture innovation through collaborative contracts, policies and regulations. Further, it was highlighted that a culture of innovation needed to be developed to help nurture competencies and capability within the industry workforce.

This study provides an in-depth examination of the need for innovation from the point of view of building industry practitioners. This study provides a useful starting-off point for further research and for the creation of policies that could help to support and accelerate innovation within the NZ building industry.

NZ’s building industry productivity and efficiency have been sub-optimal relative to other industries. But using evidence from the experiences and knowledge of industry practitioners, strategies can be developed to accelerate innovation within the NZ building industry that could help reverse industry performance. Further, the research findings can help inform government policies to develop support mechanisms that could encourage innovation in the industry in NZ. In addition, it is anticipated that the findings will provide a useful set of guidance for other countries that have similar market and physical constraints as those encountered by NZ.

There is a dearth of empirical studies on innovation in the NZ building industry which the current study contributes to. By sharing industry practitioners’ experiences and knowledge of innovation, the paper seeks to counteract more technocratic and technological optimist accounts of innovation within the building industry. Further, the paper provides insights into how the NZ building industry can transform its performance through innovation.

The purpose of this research is to measure incompatibilities between the manufacturing approaches (MA) used by the manufacturing industries, and those used for the off-site construction (OSC) of buildings. The aim is to explore which of these approaches could be integrated into OSC in a precise manner as viewed by architects as well as how this might occur.

An empirical research and empirical cycle (EC) was adopted as a methodological framework to measure incompatibilities. A combination of quantitative and qualitative mixed methods was explored through a literature-based case study of prefabricated houses and cars, nine real-life projects built by the second author's research team and the first-named author's practical experiences of leading these projects, based on a logic framework derived from the authors’ reflections of their architectural practices.

The findings quantitatively present the incompatibilities between cars (automobile bodies) and prefabricated houses. Design-related aspects have the most potential for integration (42.3% increment). The key lessons were identified as specific design philosophies and related guidelines for architects.

The findings are limited to single types of products (cars) and buildings (prefabricated houses) in particular regions. The key lessons just present a preliminary evaluation of the application of the design philosophies and related guidelines in nine real-life projects to comply with word limit constraints.

This study could help architects and other practitioners to locate and target and alleviated incompatibilities between MA and OSC. It could also precisely identify integration shortcomings to optimize decision-making as well as technical pathways for possible and effective breakthroughs.

This study provides fundamental research as a starting point for further discussion and development. A series of additional in-depth investigations combined with case studies are planned for the future. These could provide alternative study approaches to develop more appropriate architectural design methodologies and more streamlined processes.

The research contributes an alternative architectural perspective when measuring incompatibilities between MA and OSC. The results highlight the implications of precise measurement and provide guidance for architects. These facilitate the effective and successful integration of MA into OSC of buildings and promote the uptake of lean construction (LC) in OSC.

The ascendancy of modular offsite construction (MOSC) over traditional construction methods is well known. Despite the known potential of this construction approach, its adoption is minimal in New Zealand construction industry. This article investigates the potential benefits of using MOSC for delivery of high-rise buildings in New Zealand, underlying factors responsible for its low uptake and the measures that can facilitate its improved uptake.

This study utilised a mixed research approach. An empirical questionnaire survey was carried out with New Zealand construction industry professionals with expertise in MOSC. Factor analysis of survey data was carried out using SPSS software. Semi-structured interviews were carried out with subject matter experts to get further insights and expand the survey findings. Interview data were analysed using thematic analysis.

Study identified benefits of MOSC, thus establishing potential of its uptake for high-rise building construction. Constraining factors were investigated, most pronounced being low level of skills in construction industry to design, manufacture and integrate supply chain of MOSC, high initial investment, high cost of importing modules and negative perception about offsite manufactured buildings. This study also highlighted the enablers to improve uptake of MOSC. These enablers included; loan and mortgage policies to suit MOSC paradigm, building regulations to support OSC industry, increased support from the government and awareness and acceptance of standardised building designs among the clients.

Originality of this paper harps from little to no research carried out to investigate use of MOSC for high-rise buildings in New Zealand context.

This research aims to propose a comparative environmental analysis of conventional and prefabricated construction techniques utilizing a building information modelling (BIM) technique.

A set of indicators are selected to assess the environmental emissions throughout the construction life cycle, based on BIM platform. An existing project involving ten apartment buildings in Shanghai is selected as a case study.

The results reveal that prefabricated construction demonstrates environment-friendly performance with some exceptions of acidification and mineral resource consumption. Environmental impacts can also be further reduced by increasing the projected area ratio and percentage of project prefabrication.

Overall, the proposed method can be used to identify relevant environmental merits and for decision-making of appropriate construction techniques in building construction projects.

This paper aims to develop a set of affordable space and dimensional standards for market-driven low-income housing in Indian context for the purpose of mass production using industrialised building system.

For this, the paper first explains the significance of standardisation from the literature and revisits the codes and contemporary practices in industrialised building system (IBS) in India. Next, it undertakes a market survey of ongoing/completed housing projects to study the space/dimensions reflected in the market demand by the people. After considering conditions like modular grid suitability and provisions of code, it identifies a set of dimensional standards of activity spaces, emerging from the market study. It also suggests a framework of modular units showing the incremental attachment possibility for component-based construction using IBS. These standards and design frameworks will make the path for developing various products and components towards an open system in India.

The paper gives an insight of the market trends of low-income housing, focusing on unit designs and spatial elements.

Local contextualisation during the unit designs will be required and that is not addressed in this paper.

This will benefit developers, manufacturers, designers as well as policymakers towards a market-driven housing delivery using IBS.

As a result of this standardisation, housing delivery will be faster and there will be more numbers of market-driven affordable housing in masses for low-income people, thus solving housing shortage.

A developing country like India is a diversified country having many geographical and social variations. Such standardisation for a space and design framework has never been attempted before and will make a contribution for the public housing sector.

As a strand in industrialization movement in architecture, engineering and construction (AEC) industry, prefabricated construction (PC) has gained widespread popularity due to high efficiency, energy saving, low environmental impacts, safety and other advantages of PC. Well-managed supply chain can further leverage the advantages of PC. However, there is a lack of more systematically overview of the prefabricated construction supply chain (PCSC). This paper aims to comb the current status and look into the future direction of PCSC by reviewing the existing research.

In total, 131 articles related to prefabricated construction supply chain management (PCSCM) from 2000 to 2022 have been collated to (1) conduct a bibliometric analysis by using VOSviewer, including the literature sources, keywords co-occurrence, co-authorships, authorship citation and country active in the field of PCSCM; (2) classify and summarize the status of research in PCSCM through qualitative discussion and (3) point out the future research directions.

In total, 131 articles are carried out for bibliometric analysis and in-depth qualitative discussion, the visualization maps and the main research themes in the field of PCSCM are obtained. The results show that supply chain intelligentization and informatization are hot topics. Finally, future research directions that should be paid attention to in the field of PCSCM are pointed out.

This study can help project managers understand the current status and problems of PCSC operations and provide a basis for future management decisions.

Compared with previous studies, this study adds the dimension of “article authorship” to the quantitative analysis and discusses the research themes in the field of PCSCM in a comprehensive manner. In addition, this paper deeply discusses the main research topics from both the specific contents and research methods adopted.

The Japanese prefabrication industry not only has automated its processes to a high extent, but it also innovates due to the fact that it delivers buildings of outstanding quality accompanied by a multitude of services. In order to explore and specify the concepts and parameters that have driven this industry, Japan's prefabrication industry, its cultural, economic and technological surrounding, as well as the applied processes, technologies and economic strategies, have to be illustrated and analysed. The purpose of this paper is to identify, describe and analyse these concepts and their related parameters, as well as to recognise the most influential drivers for the future that provide an indication into which direction the industry could evolve.

Being aware that literature does not provide relevant information and data, which would allow the authors to explore concepts and parameters explaining the success of the Japanese prefabrication industry, the authors performed field surveys, visited factories, R&D centres and sales points of all major Japanese prefabrication companies. In some cases the authors also interviewed general managers, researchers and developers, and academicians at Japanese universities. Based on an extensive literature review in the area of product development, production technology, modularisation, mass customisation, and innovation, the authors qualitatively and quantitatively analysed all major prefabrication companies according to a fixed scheme.

The concepts and parameters identified and analysed in this paper demonstrate that the Japanese prefabrication industry, which is leading in large‐scale industrialization, nowadays focuses towards services that are related to the building's utilisation phase, rather than delivering products. By involving customers it enhances the companies' customer relations, thus creating competitive advantages.

Overall the paper identifies that Japanese prefabrication industry acts rather like a “production industry” than a “construction industry”. Similar to many other high‐tech industries, Japan's prefabrication industry incorporates the latest product and process technologies and combines automation, products and services into complex value‐capturing systems.
