Tunnel Inspection

Regular inspection of tunnel surfaces is an important practice from both a safety and tunnel asset management perspective. However, inspection for cracking and spalling is still predominantly a manual task, which is time consuming, subjective, and exposes on-foot staff to risk. This presentation will explore the use of 3D laser scanning technology and artificial intelligence to automate the inspection process with a Canadian metro case study being presented.

The construction industry has played an essential role in the process of modernization and industrialization and it has also been a major factor in determining the development of the infrastructure for other economic sectors. Construction companies consider the measurement of work progress, which often wastes time and has a low resolution, to be one of the most challenging problems faced by project management. Therefore, this research aimed to propose practical solutions by applying recent technological achievements of the 4.0 industrial revolution to improve the efficiency of the quantity management process. By utilizing the advantages and features of a BIM model and 3D laser scanning, this paper proposes that adopting a BIM model and 3D laser scanning has the potential to improve the accuracy and efficiency of the quantity management process. The case study demonstrated some typical tasks to evaluate accuracy and efficiency as well as to showcase the research proposal.

<p><strong>Abstract.</strong> Time effects and human offenses threaten cultural heritage. The constant observation and periodic maintenance activities are the most suitable safeguarding solution: they can limit risk situations and facilitate interventions. Today, planned conservation is thus the best pattern to preserve the monuments as focused on small preventive restoration: actions organized and structured according to steady and regular monitoring. The preliminary survey, the interpretation of metric and material data and the subsequent verification of the evolution of instability and degradation phenomena based on a comparison with previous information, is a long and expensive activity if carried out by traditional systems. Otherwise, 3D laser scanning and image-based reconstruction methodologies &amp;ndash; if properly applied within optimized operational practices &amp;ndash; can allow both the systematic control of assets’ conditions and the evaluation of their health status and decay problems in a short time and with lower costs. This paper intends to show the validity of such an innovative methodology through a case study applied to the former church and convent of <i>Sant'Agostino</i> (St. Augustine) in Bergamo.</p>
