INFLUENCE OF SCOPE CHANGES ON PROJECT DELIVERY OF ROAD CONSTRUCTION PROJECTS IN RWANDA. A CASE OF SELECTED ROAD CONSTRUCTION PROJECTS BY NYARUTARAMA PROPERTY DEVELOPERS (NPD)
Abstract
Poor cost performance is a typical problem in construction projects where few projects were completed within the original estimated cost. This study investigated the influence of scope changes on the project delivery of road construction projects in Rwanda, with a specific focus on selected projects undertaken by Nyarutarama Property Developers (NPD). Road construction projects are vital for infrastructure development in Rwanda, and the effective management of project scope is crucial to ensure their successful completion. This study was guided by the Theory of Constraints. This study adopted a descriptive survey research design. The target population of this study was one hundred twenty-eight employees at NPD dealing with road construction. A sample size of 97 respondents was conducted from a target population using Yamane’s Formula. The study utilized secondary data taken from pertinent documents sourced from construction company in Rwanda. Additionally, primary data was collected through the administration of questionnaires. The analysis and interpretations of the research was grounded in the perspectives provided by the respondents. The participants received surveys, interviews, and observations, utilizing various methodologies and motivations. Each item contributed to the emergence of a variable. The researcher requested participants to carefully examine the instruments in terms of their face-to-face and content validity. The test-retest approach was employed to ensure reliability. The Cronbach's coefficient was utilized to assess the reliability of the devices. A test value of 0.7 was considered sufficiently high, therefore indicating the reliability of the tools. The utilization of concurrent triangulation was employed in order to enhance the credibility of the study. A structured questionnaire was used to obtain primary data as well as descriptive statistics to analyze data. The study used SPSS Version25 to analyze the data. As such, it was utilized inferential analysis and Pearson’s correlation analysis with the aim of determining the strength between the independent variable as well as dependent variables. The findings reveal that scope changes during road construction projects in Rwanda frequently lead to delays in project completion (with 56.6% agreement), often resulting in increased project costs (47.0% agreement) due to evolving project requirements (51.8% agreement). Furthermore, inadequately managed scope changes adversely affect project timelines (56.6% agreement) and necessitate adjustments in project resources and staffing (53.0% agreement). While the project team was perceived to be adequately prepared to handle scope changes (56.6% agreement), changes in project scope were often initiated and approved based on clear criteria (61.4% agreement), indicating the importance of transparent processes in scope management. In conclusion, effective management of scope changes in road construction projects in Rwanda, exemplified by Nyarutarama Property Developers (NPD), is vital to ensure project delivery within established timelines, budgets, and quality standards while adhering to regulatory requirements. To ensure the successful delivery of road construction projects in Rwanda, including those by Nyarutarama Property Developers (NPD), it is imperative to establish a robust change management process that integrates effective stakeholder communication, rigorous cost and timeline assessments, and compliance with local regulations to manage scope changes efficiently and minimize their impact on project timelines and budgets. For further studies, it would be valuable to conduct a comprehensive comparative analysis of the impact of scope changes on the delivery of road construction projects in Rwanda, exploring case studies from multiple construction companies to identify best practices and specific challenges unique to the region.
