Environmental and Social Sustainability in UK Construction Industry: a Systematic Literature Review
European Journal of Economics and Business Studies, 2019
Research on sustainability in the construction industry is common in construction journals addressing the potential adverse effects conventional practices have in the construction community. Sustainability is addressed through the environmental, social and economic impacts in literature and researchers and practitioners always drive the need for an equal attention on these three dimensions, but not so successfully at present. Sustainability covers a broad content with various suggested approaches arising from different countries all over the world. Previous studies have investigated sustainable construction issues as a global concept and in individual developed countries such as the US, Australia, and China. The aim of this research is to investigate the extent of coverage, by academia, of the sustainability concept in UK construction industry, with a focus on the environmental and social aspects of sustainability, based on the Triple Bottom Line framework. The researchers conducted...
Current Practices Towards Achieving Sustainable Construction Project Delivery in the UK
The construction industry should play a vital role in helping efforts towards the attainment of sustainable development in the world. It is therefore becoming a key requirement for construction organizations to deliver projects that address the environmental, economic, and social dimensions of sustainability. The aim of this paper is to examine how UK construction organizations are actively engaged in sustainability practices. This paper presents the results of an investigation using a mixed methods approach of both qualitative and quantitative data analysis. Data collection involved phases of detailed semi-structured interviews, followed by an industry-wide survey of 200 intra-organizational leaders in UK contractor and consultant organizations. The analysis of the collected data revealed that construction organizations are engaged in sustainability practices such as procurement, design, waste management, whole life costing, materials and resources use, corporate social responsibility, and community engagement in the delivery of construction projects. The survey results show that construction organizations in UK are actively engaged in sustainable waste management followed by sustainable design. The results show where construction organizations are doing well and where organizations need to double their efforts in terms of implementing sustainability practices

The significant ill-performances, challenges, and increasing competition within the construction sector are generating tremendous changes. One such revolution is the transition towards offsite construction (OSC). Although a plethora of studies has expounded the virtues and benefits of the approach, a holistic review and conceptual framework of the drivers of OSC is not well-established. This research draws on a multistage methodological framework of a systematic literature review, plenary discussions, and the total interpretive structural modelling (TISM) approach to build a holistic conceptual framework for the drivers of OSC. A review of 32 empirical studies distributed across four continents resulted in the extraction of 86 drivers. The 86 drivers were grouped into time, cost, quality, productivity, innovative competitiveness, market, sustainability, and policy clusters of drivers drawing on previous classifications in empirical studies. The TISM modeling revealed three hierarchi...
A systematic managerial perspective on the environmentally sustainable construction practices of UK
Environmental Science and Pollution Research
Construction industry, though is the backbone of any economy, still add a significant portion of emissions, utilising energy supplies, and reasoning in bulk of waste production. The sustainable construction practices are the only solution considering the global climatic challenges. Owing its enormous benefits, a lot of sustainable constructions projects are built around the world, both in developed and developing countries. However, considering the innovative material and technological involvement, and lack of knowledge and expertise, such sustainable construction projects are not always successful. This research aims to investigate the barriers and factors impacting sustainability in the construction projects. More specifically, its primary purpose is to have the perspective of managers on the actors and barriers of sustainable construction in the UK. A mixed method was used to collect the data, one in the mean of questionnaire survey, and the second through the case study. To acqu...

The social dimensions of sustainability's three bottom lines are often overlooked in the construction industry. This is despite attempts to find optimal trade-offs between economic growth, environmental impacts, human health and well-being, as well as social considerations. This study reviews the literature on social sustainability (SS) within the construction arena, identifies research gaps and proposes a forward-looking research agenda. This critical review employes the 'Preferred Reporting Items for Systematic Reviews and Meta-Analyses' (PRISMA) technique to retrieve secondary data on SS from available academic, government and industry documents. The literature analysis focuses on seven themes: (1) definition of SS, (2) the theoretical dimensions of SS, (3) primary stakeholders, (4) policy and guidelines, (5) major SS performance indicators, (6) barriers to SS uptake in the construction industry, and (7) SS drivers in the construction industry. The review identifies primary stakeholders and proposes a list of assessment criteria that can be used by the construction industry in measuring progress towards SS. The study proposes a conceptual model that maps out key stakeholders, the major barriers, and enablers of SS in construction projects. The findings will support the development of SS guidelines specific to the construction industry in Australia as well as overseas.
An analysis of sustainability practices in the construction sector: A critical review
2018
As a major sector contributing to economic development, the construction industry also has substantial impacts on the environment and society. There are numerous environmental issues derived from construction activities such as outdoor and indoor environmental pollution, greenhouse gas emission, and influences on the ecological environment. As a response to these contests, the shift of the construction industry from the traditional paradigm towards more balanced development among the economic, social and environmental dimensions, i.e. sustainable development, has received global attentions. Even though many studies have been conducted on sustainable manufacturing, the critical assessment conducted in this study posits that there is much gap to be covered as far as research in this filed is concerned. Considering this gap, this study aimed at theoretically assessing sustainability in construction sector. The results of the critical appraisal of the current literature, clearly illustr...

Implementation of Sustainable Practices in UK Construction Organizations: Drivers and Challenges
The construction industry is a very important sector in achieving society’s sustainable development goals; however the change towards sustainability is a process that presents challenges. The construction industry provides benefits to society as well as causing negative impacts; this makes it a key sector in the delivery of a sustainable built environment. The quest for sustainability has put enormous pressure on construction organizations from the government and the general public to improve on its currently unsustainable pattern of project delivery. It is becoming a key requirement for construction organizations to deliver projects that addresses the environmental, economic and social dimensions of sustainability. This research investigates the drivers and challenges facing construction organizations in United Kingdom (UK) in attempting to embed sustainable construction practices. This issue is a strand of work within an ongoing PhD study on the topic “promoting sustainable practices through leadership in construction organizations”. A qualitative study with fifteen (15) UK construction organizations is presented. It involves interviews with leaders in these organizations including; sustainability directors, managers and consultants. This research examines the factors driving these UK construction organizations to adopt and promote sustainable practices. It also critically examines key challenges affecting the effective implementation of sustainability in construction organizations. The analysis of the collected qualitative data revealed that, for many construction organizations, the key driver to pursue the sustainable agenda is their reputation as a green company. They also believe that, it’s good for business as it helps them win more contracts. However, one major challenge facing construction organizations, according to the findings from the interviews is a lack of client demand for sustainability due to a wrong perception of high cost associated with sustainability.
Exploring Offsite Construction for the Construction Sector: A Literature Review
Proceedings of the 31st Annual Conference of the International Group for Lean Construction (IGLC31)
The construction sector is one of the largest producers of Gross Domestic Product globally and yet has shown little innovation in the last 20 years. Offsite has been touted as cheaper, faster, higher in quality and more environmentally friendly than onsite construction. The purpose of this paper is to review the current research into offsite construction and determine the barriers to adoption and benefits facing offsite construction. A systematic literature review was undertaken to gather relevant knowledge surrounding the subject matter using a database search of Scopus. It was found that knowledge was the largest barrier to adoption and that transcended multiple stakeholders, from the selection of the appropriate delivery methodology, how to design for optimized fabrication and finally how to interface with the onsite requirements. The benefits are a higher build quality, shorter project duration as both site work and fabrication occur at the same time, improved safety, and less material wastage. The Barriers come from design freezes earlier in the process and inflexible design for customization later in the build.
