“…For instance, a field crew might be struck by a truck because of the incorrect information regarding the location of the truck and the crew and consequently, the distance between them. Another example is utility strikes by mechanic excavations scenario attributed to the incorrect location information of buried utilities [48]. Thus, there is a need to provide a quantitative measure of the reliability of the estimated tag location.…”

“…The process starts with the one-call center contacting the utility service providers that fall within the center's jurisdiction, after which the utility providers mark the surface using either one or a combination of spray paint, flags, and stakes as shown in Figure 1. When the digging begins, the markers are the first elements to be removed and the excavation operators must either rely on memory to find the location of the utility [21] or go through the one-call system again, which will inevitably cause a delay in the project. Even with the diligent efforts of each state's one-call system, the reality is that many undocumented underground utilities still exist throughout the nation.…”

“…GIS is an effective tool for asset management because of its ability to integrate spatial and non-spatial data in a centralized database platform with real world geographical coordinates [22]. With the advent of global positioning systems (GPS) and more modern global navigation satellite systems (GNSS), GIS technology has advanced exponentially and is now being used in a plethora of contexts including educational training, AR, and various scientific disciplines [21,[32][33][34][35][36][37]. GPS and GNSS are systems of geosynchronous satellites that orbit the Earth, providing location and time information to millions of users spread across the globe.…”

Integrating Geographic Information Systems and Augmented Reality for Mapping Underground Utilities

et al. 2019

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.

Currently, utility information such as alignment and owner information is mostly managed in 2D CAD files or 2D geographical information system (GIS) models, which have limited capacity for analyses and are sometimes not updated. This paper presents an integrated 3D framework based on building information modeling (BIM) and GIS technologies for managing and analyzing utility information. In the framework, underground utility networks are modeled and represented in GIS software to facilitate visualization. Semantic information such as owner information and inspection records are also included in the 3D representations of utilities in GIS software. The GIS models are then integrated in a BIM environment based on ArcGIS using our developed BIM-GIS integration framework. The BIM-GIS framework supports various analyses such as clash detection. Clashes between existing utility networks and the designed pipelines can be identified and resolved virtually ahead of time. Changes of the utility models can also be updated conveniently in the integrated BIM-GIS framework. An example scenario that is used to test and evaluate the developed framework will be presented in this paper.
