- Abstract
Purpose: The deepening housing deficit in Africa appears unmanageable by the current escalating costs of conventional building materials from economic recession. The shortfall is exacerbated by the rising population growth, particularly in Nigeria. Despite the research evidence of the capability of alternative construction materials (ACMs) to replace conventional materials, their use in building construction is established to be low in the country. This study therefore examines the drivers and barriers of ACMs in building construction in Nigeria. Design/methodology/approach: The study conducts a self-study structured questionnaire survey on building construction professionals. The professionals, the unit of analysis, are purposively sampled. The study area is Nigeria. Findings: The key drivers to using ACMs include minimization of construction waste, low cost of ACMs, promotion of sustainable development, and energy efficiency. The analysis shows that these variables are significant in facilitating the use of ACMs in the Nigerian building sector. The results also establish an existing correlation between the barriers to the use of ACMs within eight (8) main components. These are cost-related barriers, support-related barriers, design-related barriers, market-related barriers, professional-related barriers, convention-related barriers, social barriers, and policy-related barriers. Practical implications: The instruments of government support that enhance a large commercial scale production of ACMs and use are expedient to raise the level of confidence of stakeholders on the use of ACMs in Nigeria. Institutions of learning, professional bodies, and technological research and development institutes also have crucial roles to play in the general acceptance of ACMs in building construction. Originality/value: The study provides information to solving social housing problems towards national economic development and growth.
