The role of project delivery methods on the execution of construction projects in the Kenyan judiciary

The Kenyan Judiciary's construction industry experienced a significant upturn with 63 major court projects funded by the World Bank and Kenya Government from 2012 to 2021. However, these projects faced delays and scope changes, affecting performance indicators like time, cost, site dispute, and quality. The study hypothesized that project delivery methods have no significant influence on the execution of court-building projects in relation to time, cost, site disputes, and quality. Reliability was tested using Cronbach's alpha technique, and validity was tested using principal component analysis (PCA). This study combined the collection and analysis of quantitative and qualitative data using a mixed-methods approach. Sixty-three projects were surveyed using a convergent parallel mixed-survey design. Document analysis was used to obtain secondary data, and questionnaires and interview guides were used to collect the primary data. Correlation and regression analysis techniques were used for inferential statistical analysis. The slope coefficients were considered significant at p ≤ 0.05. Thematic and document analyses were applied to the qualitative data to triangulate the findings with the quantitative data. According to the study, project delivery methods significantly influenced the execution of construction projects in terms of quality, cost, and site disputes, but not time. The study further highlights the need for flexible, context-specific project delivery approaches in the Kenyan Judiciary to ensure timely completion of court-building infrastructure.This research offers helpful information concerning the use of appropriate delivery methods to scholars, practitioners of project and construction management, policymakers, and other parties involved in implementing the Kenyan Judiciary's court-building infrastructure.
