Policy barriers to sustainable construction practice in the Nigerian construction industry: An exploratory factor analysis

Purpose: Sustainable construction practice is structured on regulatory and non-regulatory policies in developed and most developing countries. With the gradual uptake of sustainability concerns in the construction industry, this paper aims to identify the strategic need for clear-cut policies to improve sustainable construction practice. Previous studies have harped on the need for regulatory and industrial/organisational policies on improving sustainable construction practice within the Nigerian construction industry. Design/methodology/approach: A questionnaire survey was used to evaluate the perspectives of construction professionals on the policy barriers for sustainable construction practice in Nigeria, and 46 policy barriers were identified. A total of 249 questionnaires were returned and useable for analysis. Findings: Factor analysis revealed four clusters in the policy barriers to sustainable construction practice in the following order of significance: implementation strategies for sustainable construction practice, owners/client inputs for sustainable construction practice, stakeholder’s policy barriers and governmental and regulatory policy barriers. Practical implications: Mitigating the identified barriers through effective policies will require adequate inputs from all relevant policymaking stakeholders and ensure improved sustainable construction practice among stakeholders and policymakers in the industry. This will in turn set a high standard and promote the practice of sustainable construction. Originality/value: This study goes a step further in identifying the policy issues needed to ensure a smooth implementation of sustainable construction practice. The research findings will serve as a guide for policymakers in developing countries that through mitigation of the identified barriers, sustainable construction practice will be promoted.
