DEVELOPMENT OF AN INCLUSIVE SUSTAINABLE ADOPTION SUPPORT FRAMEWORK (ASF) FOR OPTIMIZING PREFABRICATION ADOPTION IN NIGERIA’S HOUSING DEVELOPMENT INDUSTRY

Abstract

The Nigerian housing development industry can contribute to Sustainable Development Goal 11, through innovative construction adoption, for optimizing affordable housing. This paper presents a framework developed through a mixed research methodology. Using a purposive sampling technique, 397 private developers, and members of the Real Estate Developers Association of Nigeria (REDAN) in Lagos and Abuja were selected. Technology Acceptance Model (TAM) and Innovation Diffusion Theory (IDT), were integrated to develop a conceptual framework, used to generate a questionnaire. An Adoption Support Framework (ASF), which is an inclusive diagrammatic representation of a five-stage innovation-decision process model, showing relationships between housing stakeholders -social structures and driven by the exchange of technical data through communication channels in a social system, was developed from data analyzed using nonparametric test, descriptive statistics, regression analysis and SPSS version 22. The ASF is characterized as being transferable, and having the capacity for abstraction and theoretical generalization.
