Eliminate Construction Accidents by Digitally Managing Buried Pipe Location Information! How to Use Scan Data

The valuable location information obtained from buried pipe scanning surveys will lose its value unless it is properly managed and utilized afterward. This article provides a detailed explanation of how to digitally manage buried pipe location information and effectively share and leverage it across an entire organization. Through digital management, the reliability and usefulness of buried pipe location information are maximized, enabling the complete prevention of construction accidents.

Building a Digital Management System

To manage buried pipe location information digitally, an appropriate system infrastructure is required. It is recommended to build an environment where stakeholders can access buried pipe location information anytime and from anywhere via a cloud-based database. A cloud system automatically provides data security, version control, backups, and so on, preventing the loss of important data.

The design of an underground pipe location information database should be carried out with future scalability and search efficiency in mind. By associating not only coordinate information but also a wide range of attribute data—such as pipe type, installation year, pipe diameter, material, and owner—the database can be put to practical use. In addition, introducing a three-dimensional GIS system enables visualization of underground pipe locations on maps, allowing users to intuitively understand the layout of the pipes.

Data security and permission management are also critically important. Information about the locations of buried pipes must be managed carefully from the perspective of preventing infrastructure terrorism. Access permissions should be configured strictly, restricting each user to access only the information they need.

On-site Use of Scan Data

Digitized buried pipe location information is directly utilized in on-site construction planning. Designers carrying tablet devices can refer to buried pipe location information in real time at the site to optimize construction routes. Digital information makes detailed buried pipe data, which cannot be obtained from traditional paper drawings, available for use in the field.

Combining this with AR display functionality makes the on-site use of buried pipe location information even more practical. Construction staff will be able to use the AR features of smartphones or tablets to check in real time which positions on the ground surface contain buried pipes. By utilizing an iPhone-mounted GNSS high-precision positioning device, the accuracy of the AR display will improve to centimeter-level accuracy (half-inch accuracy), ensuring that contact accidents with buried pipes are reliably prevented.

Multi-agency Collaboration and Information Sharing

Buried utility pipelines are owned and managed by multiple authorities. Water departments, sewerage departments, electric utilities, gas companies, and telecommunications providers—pipelines managed by different organizations are often buried in the same space. Establishing a system that enables these organizations to effectively share underground pipeline location information is critically important for improving the safety of urban infrastructure as a whole.

Adopting a standardized data format makes it possible to integrate data from different organizations. By converting the buried-pipe location information that each organization has independently acquired into a common format, an integrated citywide buried-pipe database can be constructed. Such an integrated database makes it possible to clearly understand the interference relationships among multiple buried pipes, making construction planning safer and more efficient.

Information security and inter-agency trust are also keys to multi-agency collaboration. It is necessary that clear protection rules be established for information shared among agencies, and that an environment in which agencies can mutually trust one another be constructed.

Utilization for Accident Prevention

The primary role of digitized buried pipe location information is to prevent construction accidents. During the construction planning stage, construction routes are designed based on buried pipe location information to avoid interference with buried pipes. By using digital information at the design stage, unexpected interference with buried pipes is almost certainly prevented.

During the construction phase, on-site verification using AR overlays enables even more reliable accident prevention. Before excavation work begins, on-site checks based on digital information are conducted, ensuring the locations of buried pipes are accurately identified. A verification system involving multiple staff members prevents oversights by any single staff member.

Digital information systems are also useful when unexpected buried pipes are discovered during construction. By entering information about the discovered buried pipes into the system, you can learn whether similar buried pipes may exist on other projects. This kind of information sharing helps prevent the same types of accidents from recurring.

Long-term Data Preservation and Future Use

Digitized scan data is an asset that is retained for long periods after construction completion and can be utilized in future projects. It is important that these data are reliably stored in an appropriate cloud system. Regular backups and redundancy should prevent the loss of critical data.

In future surveys of buried pipelines, comparison with past scan data will make it possible to grasp the progression of pipeline deterioration. By comparing data from multiple periods, subsidence, movement, and structural changes of buried pipelines can be detected, making maintenance and management planning for buried pipelines more scientific.

By creating a city-wide digital model of the buried pipe network, integrated management of the entire urban infrastructure becomes possible. Such integrated management dramatically enhances the safety and efficiency of complex urban infrastructure, improving the quality of life for society as a whole.

Future Developments and Expectations

Digital management of buried pipeline location information is expected to become increasingly important going forward. With advances in BIM (Building Information Modeling) technology, buried pipeline information will likely be positioned as part of the integrated information across building and civil engineering projects. In addition, by leveraging IoT technologies, it is also expected that not only the locations of buried pipelines but also their conditions (temperature, internal pressure, etc.) will be monitorable in real time.

The proliferation of iPhone-mounted GNSS high-precision positioning devices and similar technologies will make digital recording of buried pipe location information easier and more accurate. This is expected to result in the digitization of detailed location data for a greater number of buried pipes, significantly enhancing society-wide infrastructure management.
