“…Moreover, the positioning accuracy of UWB is very high, as shown in Table 1: it can achieve decimetre-level or even centimetre-level positioning accuracy. The cccuracy assessment of UWB in construction-related scenarios such as signal blockage, multipath effect, and metal surface can be found in [38], and the deterioration of UWB positioning during construction can be found in [39].…”

Mobile laser scanning (MLS) has been widely used in three-dimensional (3D) city modelling data collection, such as Google cars for Google Map/Earth. Building Information Modelling (BIM) has recently emerged and become prominent. 3D models of buildings are essential for BIM. Static laser scanning is usually used to generate 3D models for BIM, but this method is inefficient if a building is very large, or it has many turns and narrow corridors. This paper proposes using MLS for BIM 3D data collection. The positions and attitudes of the mobile laser scanner are important for the correct georeferencing of the 3D models. This paper proposes using three high-precision ultra-wide band (UWB) tags to determine the positions and attitudes of the mobile laser scanner. The accuracy of UWB-based MLS 3D models is assessed by comparing the coordinates of target points, as measured by static laser scanning and a total station survey.

“…Some potential applications of UWB technology on construction sites include material tracking and activity-based progress tracking as well as various safety-related applications (Shahi et al 2012). For instance, Cheng et al (2012) applied the UWB technology in construction projects where it was successfully used for a 3D material location tracking in real-time.…”

Abstract. The automated data collection of civil infrastructure projects, whether under construction, newly put into service, or in operation has been receiving increased attention by researchers and practitioners. Such real-time progress tracking is essential for the active monitoring of production during the construction phase of a project and for the built assets during their service lives. Automatic progress tracking can result in timely detection of potential time delays and construction discrepancies and directly supports project control decision-making. This paper outlines recent research efforts in this field and technological developments that aim to facilitate project management toward achieving project objectives. 3D imaging, geo-spatial, enhanced IT, and augmented reality technologies have recently achieved significant advances in this field. These technologies are discussed and compared herein in terms of their strengths and limitations to identify various trends concerning their applicability in data acquisition for construction projects and to formulate recommendations for their suitability in different projects. Prospects for improvement and challenges that can be expected in future research and development are considered. It is hoped that this discussion will assist construction stakeholders in choosing appropriate data collection tools, and motivate further research and development to assist in delivering projects on time and within budget.

“…In term of localization, the usage of GPS, RFID, UWB, SF, SLAM (Hammad, Wang & Mudur, 2009;Razavi & Haas, 2011a;2011b;Shahi et al, 2012;Castle, Klein & Murray, 2008) and Barcoding in AR application have improved the tracking, especially on site location. The AR application is also integrated with Natural User Interface (NUI), which fully utilizes the human movement and gesture as a medium of interaction such as kinaesthetic control, SixthSense, iHelmet, ARCADE and KinÊtre (White, Lister & Feiner, 2007;Tonn, Petzold & Donath, 2008;Mistry & Maes, 2009;Yeh, Tsai & Kang, 2012;Stein, 2012;Chen, Izadi & Fitzgibbon, 2012).…”

This paper focuses on Mobile Augmented Reality (MAR) for architectural heritage restoration as an alternative technique to visually restore the ruined rear house of Rumah Datuk Setia, Kuala Kangsar, Perak. The research consists of the development of Virtual Heritage (VH) based on the architectural heritage information of the ruined rear house, such as spatial organization, construction, ornamentation, materials; as well as "Augmented Reality" (AR) for architectural heritage restoration via mobile devices, such as smartphone and tablet. The objective is to develop Mobile Augmented Reality Restoration (MARR) of Rumah Datuk Setia, as a showcase of architectural conservation technique, for future restoration. The study reveals the process by integrating layers of architectural heritage information -VH, MAR and other enabling technologies as primary mediums for architectural heritage restoration. The research manifestation introduces a new technique of architectural heritage building restoration through MARR. It highlights necessary elements needed to be considered, and challenges, in developing the MARR, which can be applied for future architectural restorations.
