Critical Factors Affecting Construction Project Cost And Schedule Adherence In Sub-saharan Africa: A Systematic Review
Authors : Kusongwa Richard . Ngalesoni Obedi . Kiende Hussein .
Abstract
This systematic review examines critical factors causing time and cost overruns in Sub-Saharan African construction projects. Analyzing 32 articles using the PRISMA approach, the study identifies seven key factors: financial, contractual/legal, project planning/management, design/scope, external, resource, and contractor-related issues. Pareto analysis prioritizes financial, contractual/legal, and project planning/management factors for intervention, addressing 80% of delays and budget issues. The study enhances understanding of construction challenges, aiding policy design for timely, cost-effective project completion. Unlike prior country-specific research, it broadens the scope to Sub-Saharan Africa.
