Abstract: The worker’s time theft is lurking in the depths of the construction industry as an enemy. Adding more supervisors to construction sites may appear to be the obvious solution. They are left out of the more pressing matters because of non-essential and time-consuming tasks like ensuring every worker is where their timecard indicates they should be. Tracking solutions streamline back-office processes and can provide real-time site monitoring. The tracking technology of indoor construction activities can bring immediate awareness and corrective action for the project. Accordingly, this study selected hybrid Bluetooth low energy (BLE) with Building Information Modelling (BIM) technology as a tracking engine. Also, the study aims to add a layer to the 3D BIM model by visualizing the worker’s productivity. The process begins with an indoor tracking system powered by (BIM) technology, BLE, and ends with a friendly Client Early Warning System (CEWS) dashboard. The CEWS can show the percentage of completion of activity in the BIM model. Furthermore, the construction industry has been negatively impacted in various ways because of the COVID19 pandemic. The workers have had to adjust to social distancing requirements, adhere to the most recent sanitation and personal protective equipment policies, and adapt to technology to perform tasks remotely, if at all possible. In the event of a pandemic, the findings of this study will assist organizations in establishing safe working environments in which to complete their projects through an alert system in a friendly dashboard. Keywords: BIM; Bluetooth Low Energy (BLE); Client Early Warning System (CEWS); Building Information Modelling (BIM); Resources Tracking.
1. INTRODUCTION Indoor tracking continues to be a challenging task for researchers and construction companies around the world. A large number of articles and modules were written in order to track building activities through the use of a web-based or portal. Furthermore, fewer concentrated on data visualization for indoor activities [1]. This research aims to build a hybrid dynamic tracking method that incorporates both Building Information Model (BIM) and Bluetooth Low Energy (BLE) beacon signals to monitor the activity. Integrating with a document management platform using (HoloBuilder) also addresses the challenge of tracking actual indoor productivity. Nonetheless, the information loop is the bottleneck in the construction process, and capturing data on time will aid in decision-making and provide the client with an early warning. Labor productivity is one of the performance indicators used to evaluate a construction project. It defined construction productivity as the amount of work performed per hour. 360-degree photos can be used to identify the actual output manually. This study’s document management platform is HoloBuilder. Fig.1 illustrates the study’s primary approach.
