Impact of uncertainty factors on the performance of building renovation projects

What the paper says

Purpose This study aims to assess the extent of the impact of uncertainty factors on renovation project performance. Design/methodology/approach This study aims to adopt a quantitative approach, using structural equation modelling (SEM) to assess the extent of the impact of uncertainty variables on construction project performance based on data from 226 construction professionals sourced using a questionnaire. Findings The SEM result indicates four (4) principal uncertainty factors have a significant effect on renovation projects, while the remaining four (4) do not. Results of descriptive and inferential statistics showed that 25 out of 45 identified uncertainty factors have a critical impact on performance, thereby serving as the basis for exploratory factor analysis, which produced an eight-group factor solution. Research limitations/implications The research is limited to specific locations, as uncertainty factors can be location-sensitive. Further research should be done to assess the Impact of these Uncertainty factors on a specific location and other project types. Practical implications The study aids practitioners in estimating project costs and durations by identifying uncertainty factors affecting renovation projects. It aids project managers in managing uncertainties to improve cost, quality and schedule and serves as a risk management tool for clients and project managers. Originality/value The study presents a path model that shows the impact of uncertainty factors on renovation project performance. The insights provided in this study are poised to assist project managers and other construction professionals in planning renovation projects more effectively and successfully.
