Based on the investigation of the characteristics of construction sites in terms of AR technology suitability, this paper introduces the application of a new framework of ubiquitous augmented reality (AR) technology (titled U-AR) to a construction site where high mobility, free from occlusion, good accuracy, and expandability into large scale applications play a key role in meeting the practical requirements. U-AR is intended to enhance accessibility to the distributed networks that provide a gateway between a physical construction site and the digital information of AR. To illustrate the U-AR system, the detailed schematic architecture of the AR display technique, motion tracking method, and server implementation is discussed throughout the preliminary studies. The proposed architectures of U-AR present a direction of what technologies regarding display, tracker, and server should be focused for the development of the compelling U-AR. It is found that the proposed U-AR is expected to be the best suitable technology to provide AR-based visual information in construction sites.
