This paper aims to conduct a qualitative assessment of synergies between information flows of a multifamily product platform used for industrialized housing and materials passports that can promote a circular economy in the construction industry.

Using a single case study method, the research assesses the availability and accessibility of materials passport-relevant information generated by a leading Swedish industrialized housing construction firm. Data is collected using semistructured interviews, document analysis and an extended research visit.

The research findings identify the functional layers of the product platform, map the information flow using a process diagram, assess the availability and accessibility of material passport relevant information by lifecycle stage and actor, and summarize the key points using a SWOT (strengths, weaknesses, opportunities and threats) analysis.

The three main implications are: the technical and process platforms used in industrialized construction allow for generating standardized, digital and reusable information; the vertical integration of trades and long-term relationships with suppliers improve transparency and reduce fragmentation in information flows; and the design-build-operate business model strategy incentivizes actors to manage information flows in the use phase.

Industrialized construction firms can use this paper as an approach to understand and map their information flows to identify suitable approaches to generate and manage materials passports.

The specific characteristics of product platforms and industrialized construction provide a unique opportunity for circular information flow across the building lifecycle, which can support material passport adoption to a degree not often found in the traditional construction industry.

The purpose of this paper is to understand if and how industrialized house building (IHB) could support productivity developments for housebuilding on project and industry levels. The take is that fragmentation of construction is one explanation for the lack of productivity growth, and that IHB could be an integrating method of overcoming horizontal and vertical fragmentation.

Singe-factor productivity measures are calculated based on data reported by IHB companies and compared to official produced and published research data. The survey covers the years 2013–2020 for IHB companies building multi-storey houses in timber. Generalization is sought through descriptive statistics by contrasting the data samples to the used means to control vertical and horizontal fragmentation formulated as three theoretical propositions.

According to the results, IHB in timber is on average more productive than conventional housebuilding at the company level, project level, in absolute and in growth terms over the eight-year period. On the company level, the labour productivity was on average 10% higher for IHB compared to general construction and positioned between general construction and general manufacturing. On the project level, IHB displayed an average cost productivity growth of 19% for an employed prefabrication degree of about 45%.

Empirical evidence is presented quantifying so far perceived advantages of IHB. By providing analysis of actual cost and project data derived from IHB companies, the article quantifies previous research that IHB is not only about prefabrication. The observed positive productivity growth in relation to the employed prefabrication degree indicates that off-site production is not a sufficient mean for reaching high productivity and productivity growth. Instead, the capabilities to integrate the operative logic of conventional housebuilding together with logic of IHB platform development and use is a probable explanation of the observed positive productivity growth.

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.

The purpose of this study is to systematically analyse and synthesise the existing research published on offsite manufacturing/construction. The study aims to highlight and associate the core elements for adopting the offsite concept in different construction contexts. This ultimately facilitates the enhancement of the offsite uptake.

The research study was carried out through a systematic literature review (SLR). The SLR was conducted to identify and understand the existing themes in the offsite research landscape, evaluate contributions and compile knowledge, thereby identifying potential directions of future research. The grand electronic databases were explored to gather literature on the offsite concept, lean and agile principles and simulation. A total of 62 related articles published between 1992 and 2015 have been included in this study. The relevant literature was systematically analysed and synthesised to present the emerging offsite themes.

The descriptive and thematic analyses presented in this paper have identified related offsite research studies that have contributed to setting a firm foundation of the offsite concept in different construction contexts. Each of the 62 articles was examined for achieving the aim and objectives of this study, the method of data collection and coverage of offsite themes. The results of the analyses revealed that the articles mostly provide information on the offsite concept and its definitions (53 per cent) and offsite barriers and/or drivers (27 per cent). However, limited attention has been paid to the integration of lean and agile principles (13 per cent) and simulation (7 per cent) within the offsite concept, which are therefore more open to research within the offsite concept.

The literature review highlights the main themes and components of the offsite construction concept. This forms a solid basis and motivation for researchers and practitioners to build on to enhance the uptake of the offsite concept in different contexts. This study also presents a research roadmap within the offsite concept, along with a recommendation for further research to be conducted using the research framework proposed in this study. The framework could lead to validation of using simulation to integrate lean and agile principles within the offsite concept.

This paper presents a systematic review of the literature related to offsite construction in different contexts. The emerging components, that is, offsite definitions, drivers and/or barriers, lean and agile principles and simulation have been highlighted and discussed thematically. A research framework that enables pursuit of the integration of lean and agile principles offsite through the lens of simulation has been proposed. The framework is expected to open up new opportunities on the effectiveness of offsite development in different contexts.

This article aims to describe the development of industrialised house-building (IHB) to increase the understanding of the field.

The study is based on an extensive literature study and a case study with three companies, studied between 2005 and 2013 which enabled an in-depth knowledge about the companies’ development within IHB. Interviews, observations and document studies are the main sources of information in the case studies.

IHB is a complex field, consisting of several constructs that need to be integrated and continuously developed. Development of structured technical building systems has been central to the development of IHB along with developed production methods and processes. The interest in organisational fit or adaptation to industrialisation and strategy concerning business, production and products is increasing. This implies that IHB needs to be managed strategically and not on a building project level.

The article gives an orientation on how leading companies have structured and organised their work within industrialisation, giving valuable advice to practitioners with interest in the field.

This article describes the development of IHB based on studies of literature and three Swedish IHB companies’ development. This provides an aggregated view of the field’s emergence and unique information about the studied companies’ development.

To further the understanding of industrialised house building (IHB) from a temporal, emergent corporate-ability perspective, this study aims to trace the build-up of corporate assets in an IHB company over time. The research draws on dynamic capabilities, acknowledging not only what assets the company have developed and currently are exploiting, but also how these assets were develop and managed (i.e. enhanced, combined, protected and potentially reconfigured) to sustain long-term competitiveness.

A case study design was used to form a narrative that covers the evolution of an IHB company over a 25-year period. Corporate archival material, analysis of original data from a large number of research studies during 1993-2013 and retrospective reflections of owners and managers, including crosschecking interpretations of archival material, developed and triangulated the narrative.

The study presents rich empirical findings on the build-up of corporate assets. Starting from a successive process of exploration and exploitation formation of dynamic capabilities eventually played out into an exponential dynamic capability build-up. The IHB case company displays the ability to not only continuously exploit and renew resources and competences, but also to sense, seize and reconfigure cumulative assets over time. The exponential development of dynamic capabilities resonates to literature on higher-order dynamic capabilities implying that: the accumulated and higher-order dynamic capabilities are difficult to imitate and a (any) company must possess higher-order dynamic capabilities to be able to exploit and/or take up IHB.

The study is complementing and potentially challenging frequent framings of the IHB concept. Previous research has addressed and characterised IHB mainly by encapsulating a moment in time and, thus, characteristics are momentary and represent static views on IHB. However, IHB has seen a strong development over the past 25 years, and the study reflects on this development from the perspective of one of the IHB-forerunner companies in Sweden. By exploring from a company perspective the developments, reconfiguration and capacity to develop/reconfigure over time in a changing environment, the study introduces an alternative understanding of IHB as dynamic capabilities.

The purpose of this study is to describe and analyse the business model of product-oriented house-building companies and, hence, bridging the gap of knowledge on this topic. Product-orientation implies an alternative approach to house-building, requiring new knowledge about business models and its characteristics. The balance and fit between the main business model dimensions is specifically focused on to emphasise the importance of a holistic approach.

This study is based on a case study with two leading Swedish, product-oriented house-building companies. Semi-structured interviews with company executives, document studies, site and factory visits, along with seminars at the companies are the main data sources. Theories on business models and product orientation form the theoretical foundation for the study.

The case studies describe two successful companies that used end-customer knowledge to identify a target segment, develop an offering and sequentially increase control over the production and supply chain, with limited investments. This indicates that a market-based outside-in perspective is a successful approach to establish viable house-building concepts with a balance between the business model’s dimensions.

The knowledge brought forward in this study is beneficial for practitioners that can learn about product-oriented house-building and how this must be reflected in the company’s business model to be successfully applied.

The study brings forward knowledge about house-building business models that can contribute to increased house-building targeted on certain customer segments. This can be beneficial in terms of decreased costs and increased volumes of new-built, high-quality homes for a variety of customers on the market.

Business models for product-oriented house-building companies are a scarcely covered topic in previous research, and hence, this study provides knowledge of interest for both researchers and practitioners. The case studies reveal unique information of how two companies developed their successful concepts.

This paper aims to describe how the experience feedback (EF) from building projects contributes to product platform development in house-building companies. House-building companies seek improvements to decrease costs, improve flow and decrease variability. Industrialised concepts using predefinitions in product platforms have provided a way of storing and reusing knowledge in project-based house-building organisations. However, the innovation in platforms is mainly incremental and based on EF from implementations in projects.

Qualitative data were gathered via interviews, archival studies and observations, and analysed to identify the underlying structures used to manage the incorporation of EF during platform development. Four different EF channels were studied at one Scandinavian house-builder. The data are explained using an analytical framework based on diffusion of innovation, product platforms and EF.

EF is distributed over the value chain to improve the platform over time. By using multiple channels with differing contents, it is possible to balance client demands and variation with production efficiency. Platform development using feedback channels provides opportunities for double-loop learning. Operative work on projects and the strategic decisions made by developers continuously improve the platform through a combination of knowledge pull and push.

A combination of different EF channels and strategies for developing knowledge pull are shown to be essential for the incremental development of product platforms in project-based house-building organisations. The development of product platforms requires a shift away from the construction industry’s dominant project focus towards a more product-oriented view of house-building. Integrating the design phase with the supply chain enables variety but also creates a need for continuous platform development.

Humans tend to rely on beliefs, assumptions and cognitive rules‐of‐thumb for making judgments and are biased against taking more uncertain alternatives. Such inertia has implications for client organizations' decision making about innovations, which are inherently more uncertain than conventional alternatives. The purpose of this paper is to contribute to furthering the understanding of barriers to overcoming inertia in client decision making in new‐build.

A descriptive behavioural decision‐making perspective is combined with an organizational information‐processing perspective. To identify and discuss individual and organizational barriers that potentially distort clients' decision making on innovation, the analysis addresses aggregated data from four studies. The analysis focuses on inferences and interpretations made by decision makers in Swedish client organizations, their information‐processing practices and the subsequent impacts on perceived meanings and judgments about industrialized multi‐storey, timber‐framed building innovations, which are perceived by Swedish clients as new and different building alternatives.

Cognitive and organizational barriers maintain status‐quo decisions. Clients are inclined to make biased judgments about industrialized‐building alternatives because non‐applicable cognitive rules‐of‐thumb, based on their experiences of conventional‐building alternatives, are used. Furthermore, client organizations' information‐processing practices do not allow different meanings to surface, interact and potentially suggest different conclusions, at odds with established beliefs.

The paper's conclusions highlight how inertia is sustained in client decision making in new‐build. They illustrate the limitations of a common engineering approach, i.e. supporting decision making about innovations by focusing on providing more information to the decision maker in order to reduce uncertainty, as well as managing multiple meanings by reductionism.

In the construction industry, it has proven difficult to implement and realize innovation efforts, for example in the development of industrialized construction and use of platform concepts. Thus, the purpose of this study is to characterize the innovation diffusion process in the social system of a large Swedish contractor company. Specifically, the diffusion of three innovative industrialized house-building (IHB) platforms and factors affecting their adoption and implementation (particularly effects of their perceived radicality in relation to the company’s decentralized characteristics) are identified and discussed.

A case study approach was applied, using empirical material including semi-structured interviews and archival records (research reports from earlier studies at different points in time related to each innovation and annual corporate reports). The material was analyzed using Rogers’ (2003) five-stage innovation process model, acknowledging the importance of social systems’ structures.

Structural characteristics of the social system strongly affect innovation diffusion. In subsystems that had not been involved in initiation of the innovations, they were regarded as radical, which hindered their adoption and implementation.

This study builds upon the recent findings that successful innovation implementation depends on a range of contingencies in the construction context. Although the diffusion of the innovations per se has been traced over a ten-year period, generalizability is limited because the results come from one construction company.

Contractors have invested substantially in the development of industrialized construction and use of platform concepts, but less in their implementation, so they have obtained little gain. How innovations are perceived and implemented in different subsystems affects the success of their implementation in the overarching social system.

This study adheres to previous calls for more research on firm level in the complex social system of construction companies by adopting a ten-year perspective on the diffusion of innovation at a large contractor addressing in particular the impact of the innovations perceived radicality in relation to the decentralized characteristics of the company.
