“…Furthermore, in the construction industry, GPS now provides three-dimensional location information to machinecontrolled heavy equipment such as excavators, graders, and bulldozers for higher accuracy builds and cost efficiency [39]. Talmaki et al, [3] identified three limitations with the one-call practice. The first is a lack of detailed information regarding the buried utilities.…”

“…Many utility owners have switched from computer-aided drafting (CAD) systems to more robust GIS for the creation, storage, and management of their utility information [37]. For example, GIS allows utility owners to have their complete asset inventory archived in a single repository for data extraction, visualization, analysis, and updating information [3]. Therefore, GIS has the inherent ability to store attribute information about the assets in a real-world system.…”

“…In addition, the growth of urban underground space (UUS) is increasing significantly in the world's largest cities [2]. The single largest threat to the safety of UUS is being struck by a construction earthworks project [3]. In 2016, the societal damage caused by utility strikes in the US came to an estimated $1.5 billion [4].…”

Underground infrastructure is a critical component of the basic utility services provided to society. The single largest threat to the safety of underground utility lines is being struck by construction earthwork projects. One of the causes of this problem is miscommunication between utility owners and contractors. Therefore, it is vitally important to coordinate resources, share information, and ensure efficient communication between construction personnel and utility owners. Geographic information systems (GIS) provide a solution for interoperability in the construction industry. Applying such technologies in the field of underground construction requires accurate and up-to-date information. Augmented reality (AR) has been identified as a technique that could enhance information extraction from the virtual world to the real world and improve the access and utilization of information. However, there is currently limited research that has integrated AR and GIS and evaluated the effectiveness and usability of the combination in this domain. The main objective of this research was to develop an integrated AR-GIS for mapping and capturing underground utilities using a mobile device. The data are shared instantaneously with other stakeholders through a cloud-based system. In order to achieve these objectives, a design research approach was utilized to develop and evaluate a mobile extended-reality (XR-GIS) application. Validation of the XR-GIS was conducted through a focus group discussion and a questionnaire. The results revealed that 86% of the participants validated the system’s adaptivity to the underground construction. We can conclusively say that this research has produced an efficient solution for data collection and sharing among stakeholders in the underground construction industry.

“…serve as visual guidance for the excavation operator, they are vulnerable to heavy traffic, severe weather, and excavation activity which scrapes the surface and then removes the top soil, thus destroying the surface markings. This makes it challenging for an excavator operator to maintain spatial orientation, and must rely on memory and judgment to recollect marked utility locations as excavation proceeds (Talmaki and Kamat 2012).…”

“…One approach is to use only the equipment geometry and pose for the generation of DEWs [13,14,15,17,18,31,32,33]. In this approach, the space around the equipment is overconservatively reserved within a radius (r) of the equipment (called here cylindrical workspace, Figure 1(a)).…”

In the period between 1992 and 2002, struck by vehicles and struck by objects (e.g., vehicle parts, vehicle loads, or falling vehicles) were identified as the causes of 30% and 24% of deaths on excavations sites, respectively. It is therefore of a paramount importance to improve the safety of construction sites by increasing the peripheral awareness of the operators of earthwork equipment. The existing collision avoidance systems often detect collisions based on the workspaces that only account for the geometry and the degrees of freedom of the equipment, and thus disregard the job-site-andstate-dependent characteristics of equipment. This results in reserving a large space for every piece of equipment. Therefore, this paper proposes a novel method for generating dynamic equipment workspaces based on the continuous monitoring of a spectrum of equipment-related information, i.e., the current pose/state of the equipment, and the speed characteristics of each movement. This method uses the required operation stoppage time to determine how much space needs to be reserved for each piece of equipment. A case study is conducted to validate the proposed method. It is shown that the proposed method has a strong potential in capturing the hazardous areas around the equipment and triggering warnings in view of the impending movements of various pieces of equipment.
