Comparative Analysis of Impact of E-procurement and Traditional Procurement on Building Construction Project Delivery in Rivers State Nigeria

This study provides a comparative analysis of impact of eprocurement and traditional procurement on building construction project delivery in Rivers State Nigeria. A mixedmethods approach was employed, involving descriptive statistics, relative importance index, severity index analysis, factor analysis, Surveys, principal component analysis (PCA) and correlation analysis to analyze data from 180 respondents in the construction industry. Results of this study showed that e-procurement systems outperform traditional systems in efficiency, accuracy, transparency, and cost-effectiveness. A strong positive correlation was observed between the performances metrics of both systems, emphasizing that eprocurement amplifies the benefits seen in traditional systems. This strong positive correlation (0.807) shows that higher costeffectiveness in traditional procurement is associated with higher cost-effectiveness in electronic procurement. The result is highly significant, implying that improvements in costeffectiveness are similarly reflected in both systems. This strong positive correlation (0.714) suggests that time efficiency in traditional procurement is positively related to time efficiency in electronic procurement as the significant p-value indicates that the relationship is statistically reliable. Based on this finding, it is recommended that stakeholders prioritize the integration of e-procurement to leverage these advantages fully while ensuring compatibility with existing traditional methods during the transition phase.
