Abstract

Purpose

Sustainable construction practices are strongly correlated with a profitable and competitive construction industry, improved client satisfaction and efficient use of resources. However, due consideration is not being given to sustainable construction practices in Nigeria. Therefore, this study aims to identify the unsustainable construction practices on construction sites, the barriers to sustainable construction and possible strategies to improve sustainable construction in Nigeria.

Design/methodology/approach

A questionnaire survey of 50 construction sites was conducted with construction professionals on the sites as the specific target, out of which only 43 construction sites have at least a construction professional present at the site. Forty-three filled questionnaires from the respondents were used for descriptive (mean score, standard deviation and charts) and inferential analysis (t-test and Kruskal–Wallis) in this study.

Findings

The study shows that a large percentage (75%) of construction professionals in Nigeria are aware of sustainable construction. The descriptive and inferential analysis showed a disparity in the ranking of the 12 unsustainable practices, 14 barriers and 11 strategies among the respondents. Five unsustainable practices (“negative externalities”, “excess energy”, “unsustainable technologies”, “non-management of health and safety of workers” and “material waste”), six barriers to sustainable construction (“absence of historical data and exemplary projects on which construction professionals can build and learn from”, “lack of professional to handle the task”, “poverty and low urban investment”, “lack of urban and construction policy”, “lack of awareness” and “lack of technical know-how”) and three strategies to improve sustainable construction practices in Nigeria (“cooperation, partnership and participation”, “protection of biodiversity and conservation of natural resources” and “sustainability assessment system”) were found to be significant.

Practical implications

The study offers significant insights into the construction industry unsustainable practices, barriers to sustainable construction, as well as strategies for improving sustainable construction practices. These insights can be applied to other developing countries with an emphasis on geographical differences.

Originality/value

To the best of the authors’ knowledge, this is one of the recent studies in Nigeria that explored the context of sustainable construction in the construction industry by providing insights into the unsustainable construction practices, barriers and strategies to improve sustainable construction in Nigeria.

Abstract

Purpose

The changing role of quantity surveyors in the new paradigm of sustainable construction requires studies into new competencies and skills for the profession. The impact of sustainable construction on quantity surveying services, engagement and how they manage challenges provided an indication of the success indicators of the quantity surveying profession in meeting the sustainable construction needs.

Design/methodology/approach

A five-point Likert scale was developed from the list of quantity surveying firms in Singapore. An 85% response rate from 60 quantity surveying firms contacted in this study provided 51 responses. Descriptive statistics and factor analysis were employed to evaluate the findings.

Findings

The factor analysis categorised the drivers derived from the literature into awareness of sustainable construction, adversarial role on green costing; carbon cost planning; valuing a sustainable property; common knowledge of sustainable construction; and lack of experience in sustainable construction.

Social implications

The research findings supported the idea of increased sustainable construction skills in quantity surveying education, research and training.

Originality/value

The dearth of quantity surveyors with sustainable construction experience must focus on quantity surveying professional bodies and higher education. The quantity surveying profession needs reskilling in green costing and carbon cost planning to meet the needs of sustainable construction.

Abstract

Purpose

The majority of the literature on green buildings in Ghana focuses on environmental benefits, innovative designs, construction technologies and project management techniques. However, little is known about how such facilities are financed. This issue creates potential knowledge gaps, one of which this study aims to address. This study examines the key drivers for green building project financing in Ghana.

Design/methodology/approach

The study uses an explanatory sequential design with an initial quantitative instrument phase, followed by a qualitative data collection phase. An extensive critical comparative review of the literature resulted in the identification of eight potential drivers. One hundred and twenty-seven questionnaire responses based upon these drivers from the Ghanaian construction industry were received. Data were coded with SPSS v22, analysed descriptively (mean, standard deviation and standard error) and via inferential analysis (One Way ANOVA and One-Sample t-Test). These data were then validated through semi-structured interviews with ten industry professionals within the Ghana Green Building Council. Data obtained from the semi-structured validation interviews were analysed through the side-by-side comparison of the qualitative data with the quantitative data.

Findings

Though all eight drivers are important, the five key drivers for the Ghanian construction industry were identified as, in order of importance, “high return on investment”, “emerging business opportunity”, “ethical investment”, “conservation of resources” and “mandatory regulations, standards, and policies”. The interviewees agreed to and confirmed the importance of these identified drivers for green building project financing from validating the survey's key findings.

Research limitations/implications

Key limitations of this study are the restrictions regarding the geographical location of the collected data (i.e. Kumasi and Accra); timing of the study and sample size (i.e. the COVID-19 pandemic making it difficult to obtain adequate data).

Practical implications

Though this study was conducted in Ghana, its implications could be useful to researchers, policymakers, stakeholders and practitioners in wider sub-Saharan Africa. For instance, financial institutions can invest in green buildings to expand their green construction and mortgage finance products to build higher value and lower risk portfolios. The findings from this study can provide investors with the enhanced certainty needed to help guide and inform their investment decisions, i.e. what to invest in, and when, by how much and how a scheme being “green” may influence their rate of return. Also, for building developers, it will give them a clearer understanding of the business case for green buildings and how to differentiate themselves in the market to grow their businesses.

Originality/value

This study's findings provide insights into an under-investigated topic in Ghana and offer new and additional information and insights to the current state-of-the-art on the factors that drive green building project financing.

Abstract

Purpose

During the last decade, the practice of sustainability has been gradually adopted in the UK construction industry, with the increasing interest in the discourse of sustainable development. This paper therefore aims to investigate the role and ability of sustainable development-based requirements – top management commitment, government regulations and construction stakeholder pressures – as potential determinants of adoption of proactive environmentally sustainable practices, with a view of promoting sustainable innovation in the UK construction industry.

Design/methodology/approach

The research approach selected for this research comprised of a questionnaire survey of the UK construction industry practitioners – architects and designers, structural engineers, construction managers and quantity surveyors – with the aid of an Adobe Livecycle Designer. Purposive sampling techniques using maximum variation strategy were adopted for selecting the target survey respondents. The Predictive Analysis Software (PASW) Statistics 17.0 (formerly SPSS statistics) was employed to analyse information from the survey.

Findings

Empirical results indicate a positive effect of government regulations, top management commitment and construction stakeholder pressures on sustainable construction practices. Government regulation was found to be the most important determinants of sustainable practices. In addition, top management commitment appears to be linked with government regulation as the defining factor increasing managers sustainability awareness, helping sustainable practices to be effectively implemented and appealing to firms.

Originality/value

The research results provide useful information in understanding the determinant factors of sustainable construction innovation and are particularly essential in aiding better decision-making in implementing sustainable practices, thereby facilitating the sustainability of the construction sector.

Abstract

Purpose

Sustainability in construction is a challenging task for contractors due to diminishing natural resources and increasing energy costs. The purpose of this paper is to identify key issues that affect the adaptation of sustainable construction practices by Sri Lankan contracting organisations and propose a framework for successful adaptation.

Design/methodology/approach

Eight semi-structured interviews are conducted from three selected case studies to gather data on sustainable construction practices and related issues in contracting organisations in Sri Lanka. The proposed framework is validated and enhanced by interviews conducted with seven industry experts in Sri Lanka and the Persian Gulf region. A cross-case with code-based content analysis is used to analyse the data.

Findings

Gaps in the legal framework and weak enforcement of prevailing rules, less institutional intervention, less commitment of people especially key stakeholders, wrong perceptions on capital costs, and low levels of education and experience on sustainable construction are identified as key issues, similar to the Persian Gulf region. The proposed framework presents suggestions for successful adaptation of sustainable construction practices in the following eight key areas: legal framework, standards, guidelines or policies, design, procurement, technology, processes and innovations, people and organisational structure, education and training, and measurements and reporting.

Research limitations/implications

The scope of this research is limited to the data gathered from C1 category construction contractors in Sri Lanka and similar category in the United Arab Emirates of the Persian Gulf region.

Originality/value

The framework for the enhancement of sustainable construction practices via contracting organisations is proposed as an inaugural step to establishing a country-based and industry-specific model to achieve sustainability in the Sri Lankan construction industry.

Abstract

Purpose

The purpose of this study is to assess the drivers, practices and policies for implementing sustainable construction in Nigeria. This is with a view towards increasing the rate of implementation and diffusion of sustainable construction practice, so that more Nigerians can benefit from its environmental, social and economic dividends.

Design/methodology/approach

This study adopted a qualitative research design with the use of face-to-face oral interviews. Interviewees were selected using a purposive sampling technique. Data from the interview were analysed using thematic analysis. Descriptive statistics of frequencies, percentages and rankings were also used to present the data and complement the thematic analysis.

Findings

The study identified five major drivers of sustainable construction: clients' demand, international pressure, corporate social responsibility, competitiveness and cost-effectiveness. The common sustainable practices adopted by the interviewees are compliance with health and safety regulation, waste management, energy efficiency and material reuse. The most appropriate policies for implementing sustainable construction as suggested by the interviewees were government regulations, provision of tax relief and subsidies and public awareness. A combination of regulatory policies, market-based policies and voluntary participation of stakeholders will enhance the attainment of sustainability transformations in the construction industry

Originality/value

The study is based on the findings of construction participants who have practical experience with sustainable construction in Nigeria. The study also provides empirical evidences which could guide the design and implementation of policies that will further promote the diffusion of sustainable construction in Nigeria

Abstract

Purpose

Adopting sustainable construction practices minimizes the overall environmental impact of the built asset throughout its whole life. Currently, there is demand from key stakeholders in the construction industry for organization to deliver sustainable built environment, however, leaders/champions within construction organizations charged with the adoption of sustainable construction practices face many challenges. The purpose of this paper is to present the results of an investigation into the challenges facing intra-organizational leaders charged with the promotion of sustainable construction practices.

Design/methodology/approach

Qualitative data were collected through semi-structured interview with 15 leaders, followed by an industry-wide survey of 200 intra-organizational leaders in contractor and consultant organizations in the UK construction industry.

Findings

The results revealed that increased capital cost is the most significant challenge facing construction organizations in attempt to adopt sustainability practices in the delivery of construction projects.

Originality/value

This study provides the empirical evidence linking leadership within construction organizations and sustainability; filling the gap in literature and serving as a source of reference material for higher education programmes in the built environment.

Abstract

This research work is an introduction to sustainable construction. A few significant indicators and many related subsets, which are crucial to green sustainable construction and also to green buildings, are mentioned in this study. An ecocity is one that utilizes all the critical elements of the environment. Urban sustainable construction is a vital criterion in this context. Sustainable construction paves the way for the building industry to progress towards achieving realistic standards of performance, particularly in view of economic, environmental, and social concerns. Sustainability is a popular expression that has given rise to various activities throughout the world once people began to grasp the implications of sustainable construction. Sustainability, which is an important factor in reducing the negative environmental effects of construction, includes improving the control and efficiency in the use of raw materials, land and power consumption. The lifetime of a building is based on some factors that are prognostic regarding the manufacture, remodelling, support, utilization, and administration of the building, and finally, the sources of utilization and waste formation, annihilation and devastation. All of these give rise to a range of ecological issues in the life of a building. Generally, a sustainable building and construction involves a reduction in the utilization of energy and also wastage from the beginning of the construction process and throughout the lifecycle of the building. Moreover, the environment is faced with mounting devastation due to the exploitation of natural resources for building construction and the replacement of agronomic regions by residential areas.

Abstract

Purpose

In responding to global issues of creating sustainable development, the Indonesian government has enacted regulations (i.e. Ministry of Public Works and Housing No. 05/PRT/M/2015) on the implementation of sustainable construction in infrastructure project execution. The purpose of this paper is to evaluate the means of implementing sustainable principles in the execution of infrastructure projects in Indonesia by the main construction service providers and their partners. A lesson-learned is presented as a source of knowledge to underpin the extensive implementation of sustainable principles in the construction of infrastructure projects leading to an integrated approach in creating a sustainable infrastructure that fulfills the requirements of sustainable development.

Design/methodology/approach

The method used is questionnaire surveys with Indonesian construction practitioners who are working on building construction, road and bridge construction, water facilities construction and house and settlement construction.

Findings

From the results, the practices of sustainability principles by construction service providers in infrastructure project execution are imperative from the project procurement phase. The evaluation continues to the phase of construction project execution, which reveals the inconsiderable performance of sustainability indicators due to current constraints on the implementation of sustainability principles.

Originality/value

This research looks into the existing gaps between sustainable construction principles and their practical implementation in Indonesian infrastructure projects. This will foster a holistic approach in the practice of undertaking sustainable procurement processes, thus reinforcing project management techniques in the phase of sustainable construction project execution. This also strengthens the interrelated roles and responsibilities of project stakeholders by taking into account principles of safety, balance and the harmony of infrastructure and the environment.
