Exploring the Drivers and Barriers for Sustainable Infrastructure Projects Delivery in Sub-Saharan Africa

Abstract

Sustainability of the built environment has become an international imperative within the Architecture, Construction, and Engineering (ACE) sector. While much has been written about the drivers and the mitigating barriers to sustainability and sustainable construction in Africa, the implementation of the concept is still a challenge. This exploratory research employs an interpretative paradigm to add to what is known about the issues in sub-Saharan Africa. The collection, categorization and analysis of interview transcripts and a review of extant literature and document analysis led to salient insights. Findings show that education and experience inform a designer's understanding of sustainable design and construction and that designers' understanding of sustainable design values or lack of, affect their behaviour, attitude and likelihood to promote sustainable practice. The study found that Change strategy that equips a project actor with knowledge and skill needed to do things differently as a major factor for embedding sustainability in the construction industry. Drivers as solutions to barriers that were identified include improved knowledge of sustainable design, leadership and demands, and construction and material usage. Most importantly, there is a need for a change in clients' perception of the cost of going green.
