Development of an AR System for the Advancement of the Tasks in the Construction sites

In this paper, we developed an AR (Augmented Reality) application for productivity improvement in the construction sites. We developed this system for upgrading the ancient methods of construction by using the AR Technology. The main concept of this system is to use the AR technology for visualizing the completed form of the buildings, reforming the “construction management” and improving the productivity on the construction sites. This system can be used for the “presentation of the completed models” for early decision of the task to be performed, “safety work confirmation” for eliminating and reducing the dangerous tasks, “visualization of completed model before the completion of the buildings” for eradication of serious mistakes on quality of the buildings to be build. Generally, the AR system is used along with various types of head worn devices like Head mount displays or Google glass, but they are not realistic for the construction workers or in the construction sites. Our application works on iPad® ® and tablets which is easy to use and is a realistic form of using AR in the construction sites. Our application is developed in such a way that, the AR model generated from the BIM (Building Information Modeling), projected on 1:1 scale in a real space is continuously displayed in a smart device following the movement of the person holding the tablet. As a person moves holding the tablet, the position and orientation of the tablet is tracked, and the model follows the tablet. The developed system is experimented on the building construction sites in Japan. The experiments were conducted by developing the AR models from the BIM model of the various areas of the architectural construction sites. The experimental results reflect the effectivity of our AR system for increasing the productivity of the construction sites. © 2019 The Authors.
