Purpose – The contribution of lean construction techniques in sustainable construction cannot be over emphasised, as sustainable development is now enshrined in government policy. In addition, lean construction is now faced with the challenges of sustainable development, continuous improvement, waste elimination, a stronger user focus, increased value for money along with high quality management of projects and supply chains, and improved communications. This paper presents an exploratory study from extant literature and the results of the use of questionnaire survey among construction participants to explore the contribution of implementing lean construction techniques in sustainable construction. Design/methodology/approach – Surveys of UK-based construction professional were conducted. The data collected were analysed with SPSS 19.0 version software using the percentile method, Cronbach ' s α reliability test, Kruskal Wallis test, Kendall ' s coefficient of concordance and one sample t-test. Findings – Results from this study indicate that there are several benefits associated with implementation of lean construction and sustainable construction. The overall perspective of professionals within the construction industry, according to questionnaire survey, shows that benefits such as improved corporate image and sustainable competitive advantage, improved process flow and productivity, improvement in environmental quality and increased compliance with customer ' s expectations are realised following integration of principles of lean construction and sustainable construction within construction industry. Just-in-time, visualisation tool, value analysis, daily huddle meetings and value stream mapping are the most common lean tools/techniques for enabling sustainability. This study also identified several areas of linkage between lean and sustainability such as waste reduction, environmental management, value maximisation, and health and safety improvement among others. Originality/value – The originality of this paper lies in its consideration of lean construction principles to better understand its impact on sustainable construction. This research contributes to the awareness of the benefits that can be derived from the implementation of lean construction in sustainable construction within the construction industry.
PurposeThe purpose of this paper is to report on findings from the first stage of an ongoing research with regard to the UK construction industry's perception of offsite production (OSP) adoption/uptake, in an attempt to inform the second stage of the research (not reported in this paper) to infer the skills/knowledge areas needed for the wider uptake of OSP.Design/methodology/approachThe objective of this paper was to capture the UK construction industry's perception vis‐à‐vis OSP characteristics using a quantitative approach. Postal surveys were employed to collect industry perception which was then analysed statistically for inference and conclusion.FindingsFindings from 36 large construction organisations suggest that irrespective of respondents' organisations prime activity or professions, the majority of respondents perceive OSP to be the future of the UK construction industry; with a considerable belief that the industry is ready to embrace OSP. Nevertheless, the industry do not seem to fully appreciate OSP, which is implied by the uncertainty recorded in most of the responses.Research limitations/implicationsWhilst the data validity and sample set coherence can be considered robust and defendable, it should be acknowledged that care needs to be taken when interpreting results, especially as the data collected depended heavily on the survey approach. Furthermore, these findings are limited to the UK context only, as such, the level of generalisability/repeatability outside this context may not be representative of the findings presented here.Originality/valueOSP falls under the overarching umbrella of modern methods of construction, which is high on the UK Government Agenda. OSP has attracted numerous research over the last decades; however, there is limited literature to quantify industry perception in this regard, especially to enable the inference and prioritisation of skills and knowledge areas needed to support the wider uptake of OSP (not reported in this paper).

AbstractPurpose -Recent calls were launched worldwide for the "revival" of offsite production (OSP) (under numerous nomenclatures) in order to improve the construction industry, meet market demand; and furthermore, overcome the dependence on skilled labour. Despite the well-documented benefits of OSP, the construction industry seems to be somewhat hesitant in effectively responding to those calls. Forming part of a triangulated research, this paper aims to explore the European Union (EU) construction industry main patterns of concern with regard to OSP. The findings from this paper are set to guide the development of an OSP training and education model (not reported in this paper). Design/methodology/approach -A qualitative approach using the content analysis technique was employed to analyse secondary data (transcripts) from 54 open-ended questionnaires carried out under the Manu Build EU research project, to deeply explore the EU construction industry main perceptions/concerns which may represent a barrier to the wider uptake of OSP. Findings -The EU construction industry reluctance to embrace OSP practices is largely attributable (amongst others) to the unsuccessful past experiences associated with this approach. While the findings were in line with extant literature "hard" issues/concerns such as cost and productivity, additional findings revealed "softer" issues/concerns such as the flexibility of the OSP approach, preservation of the identity of cities, and the ability to adapt OSP buildings to older generations' needs and requirements. Originality/value -This paper condensed and synchronised all OSP-related patterns of concern in a conceptual model. The model expanded on the well documented triad model of "people", "technology", and "process"; and further added the "product" and "market" pattern to it. Should all these main five OSP patterns of concerns be addressed, it is postulated that this would help support the wider uptake of OSP within the EU construction industry; and furthermore create a shared understanding between industry and training/education institutions to enable an OSP knowledgeable industry.

Managing information flow and design processes to reduce design risks in offsite construction projectsAbstract Purpose: Following the increasing need for faster construction, improved quality, and evidence value propositions, offsite construction is increasingly being proffered as a viable contender to 'traditional' construction approaches. However, whilst evidence supports the move towards offsite, its uptake has been lower than expected. Whilst the precise reasons for this seem to be influenced by a number of issues, including contextual drivers and market maturity; some project stakeholders also view offsite as carrying greater risks. This paper reports on the quality of information flow, in particular, the impact and influence of this on design risks in offsite construction projects.Design/methodology: An existing design risk framework is used as the point of departure for this research. This is further expanded into a specific model for evaluating offsite construction projects design risks, the rubrics of which were informed by two case studies of offsite construction projects in Australia and the UK analysed with a process-tracing technique. Whilst these cases were geographically separated, the constructs were aligned to uncover fundamental design information requirements and concomitant risks associated with offsite.Findings: The findings of the research reported in this paper include the crucial information feeding into the design process emanating from the lifecycle of offsite construction projects, namely design, offsite (manufacturing), handling and transporting, site works and installation and also occupancy. These are contextualised within the four categories, namely client requirements, project requirements, regulation aspects and social aspects and the final outcomes were summarised into a holistic diagram.Originality/value: Given that the offsite construction has shifted the working paradigm into assigning a significant level of efforts and emphasis at the front end of the construction projects, the importance of its design process and hence design risks management has gone up significantly in construction projects delivered using this technique. This research and paper contributes significantly to the built environment domain by identifying the crucial aspects along the project lifecycle to be considered to minimise the potential occurrence of design risks and hence increasing the confidence of project stakeholders in adopting offsite construction techniques in their projects.
Purpose -The problem of climate change is one aspect of the broader problem of sustainability. Many businesses in most sectors now accept that they must address the issue of climate change in order to survive and grow in ever-changing entangled business economies. Due to mounting pressure from stakeholders, top executives of many organisations are now implementing various carbon emissions reduction strategies. However, the extent to which businesses embrace climate change and carbon management as an integral pillar of their business models remains unclear and poorly understood. This paper seeks to address these issues. Design/methodology/approach -The aim of this research is to investigate the key carbon emissions reduction initiatives currently being implemented in the UK industrial sectors so as to improve their competitiveness. In order to achieve this aim, a mixed research methodological approach was adopted to collect and analyse data. Four industry sectors were examined, specifically: energy and utilities, transportation, construction and not-for-profit organisations; with specific respect to their environmental, social and economic impact on the UK society. Findings -The level of implementation of carbon emissions reduction strategies within the UK industrial sectors is fairly "low" and varies significantly across the four sectors; with relatively high uptake in the energy and utilities sector, and low uptake in the construction sector. The level of implementation of change management initiatives to deal with carbon emissions reduction initiatives is also relatively "low". Practical implications -This study suggests that carbon emissions reduction strategies are in their infancy. Taken together, the impact of management commitment and leadership, climate change-related policies, structures, reward systems, training programmes and performance reporting are key factors in successful implementation of low carbon strategies. The paper concludes that there is a need for cross-sector collaboration to capture and share best and worst practices relating to low carbon strategies. Originality/value -The paper provides a richer insight into the understanding and awareness of low carbon strategies for competitive advantage.
