Low productivity, ineffective management on building sites, a high risk of construction accidents, and a lack of information about project status are all issues confronting India's construction business. With the advancement of current techniques and technology, prefabricated construction is becoming increasingly popular in the construction industry. In the current COVID-19 scenario, there are a number of limitations to tracking the progress of the prefabrication building project due to a lack of real-time data collection and exchange. Today's construction firms are always on the lookout for cutting-edge technology that will allow them to meet their objectives at the lowest feasible cost while ensuring maximum worker and public safety. The Internet of Things (IoT) is the most recent technology to be implemented in the construction business. It is making it feasible for construction companies to focus more on the benefits of the internet in their projects in order to enhance procedures, minimise waste, and optimise the use of resources. Building Information Modeling (BIM) and IoT is used in this study to provide an innovative approach for monitoring prefabricated construction project progress. Ultrasonic sensors are used to determine the installation status of various project components, such as walls, columns, beams, etc. The status is then input by the site supervisor into an excel sheet generated by Dynamo, a visual programming language for Revit, and modifications made to the installation status of the component are reflected back into the Revit model, leading to fewer human errors. Prefabricated projects' monitoring will be revolutionised by this strategy …
