Applying Civil Information Modeling And Augmented Reality To The Construction Of Underground Pipelines

Municipal construction projects are often challenging and risk-prone due to unexpected underground conditions. Access to As-Built and As-Design data is essential to avoid budget overruns, schedule delays, and other construction disputes. However, coordinating field conditions with construction drawings can be difficult and lead to discrepancies. Traditional methods of denoting information onto the ground by surveyors and field workers have been limited in their ability to provide relevant information and support scaling up. These methods also create restrictions in data sharing and communication among workers and engineering teams. With the development and use of AR technology, our study proposes an augmented reality tool leveraging Google ARCore to assist construction engineers in a straightforward and efficient manner by displaying utility information, including pipe direction, type, slope, diameter, and material. The campus area of the University of Maryland College Park is used as a case study to demonstrate our approach.
