The application of BIM technology for clash detection on building construction projects in Uganda.

Abstract

The study aims to investigate the application of Building Information Modelling (BIM) Technology for clash detection in Uganda's construction projects. Specifically, the study aims to classify the various clashes occurring on construction projects and identify their underlying causes, examine the extent to which conventional and BIM-based methods have been used to resolve clashes on construction projects and compare the performance between the two methods of clash resolution used on construction projects. The research design adopted in the study is descriptive, and a mixed-method approach is used that combines qualitative and quantitative approaches. The target population includes professionals working in the construction industry of Uganda, focusing on general practitioners in construction management on various construction projects. Simple random sampling and purposive sampling techniques were used to select the sample of construction professionals working in Uganda, working for both international and local construction companies. Data was collected through a survey of construction professionals in Uganda, including close-ended questions. This data was statistically analyzed to obtain more objective and generalized insights. Qualitative data was also collected through questionnaires answered by professionals in the Ugandan construction industry, which were transcribed and coded for analysis. The study's key findings reveal that the use of BIM technology for clash detection in Uganda's construction industry would largely increase productivity by eliminating cases of rework arising from clashes. The study also found that the primary causes of clashes in Uganda's construction industry are poor communication and coordination among stakeholders, design errors and omissions, and inadequate information management. Additionally, the study found that the use of BIM technology for clash detection is more effective than conventional methods in terms of time, cost, and accuracy. Based on these findings, the study recommends that stakeholders in Uganda's construction industry should embrace BIM technology for clash detection to improve productivity, reduce costs and delays caused by rework, and enhance the accuracy of the design and construction process. The study also recommends that the government of Uganda and professional associations in the construction industry should provide training and support for the adoption and implementation of BIM technology in the country.
