“Mitigating Risk Through Pre-Inspection Structural Understanding: A New Paradigm for Waterfront Infrastructure Assessments”
Recent failures of critical structural elements in waterfront infrastructure have underscored a pressing need for a paradigm shift in how underwater inspections are approached. Traditionally, divers and inspection teams have relied heavily on in-situ assessments, often without comprehensive knowledge of the structure’s original design, modifications, or current condition. This reactive approach can expose personnel to unforeseen hazards and limit the effectiveness of the inspection.
This presentation introduces a proactive methodology that emphasizes the importance of understanding a structure’s design, materials, and historical performance before initiating underwater inspections. By integrating archival research, engineering analysis, and modern visualization tools such as 3D modeling and sonar mapping, inspection teams can better anticipate potential failure points and plan safer, more targeted interventions.
Equally critical is the ability to make informed, real-time decisions during inspections. When severe deterioration or unexpected structural anomalies are encountered, teams must be empowered to recognize the limits of safe inspection and call for an immediate “all stop.” This decision-making process—rooted in training, experience, and structural awareness—can prevent catastrophic outcomes and protect both human life and infrastructure integrity.
Attendees will gain insights into:
· Case studies of recent structural failures and the lessons learned.
· Techniques for gathering and interpreting pre-inspection structural data.
· Real-time risk assessment strategies during inspections and key indicators of hazards and potential failures. .
· Protocols for identifying critical findings and initiating an “all stop.”
· The role of interdisciplinary collaboration between engineers, inspectors, and asset owners.
This session aims to spark a broader conversation across the waterfront industry about the value of pre-inspection intelligence and dynamic risk management during inspections.
How does this project / topic contribute to the advancement of the industry and profession?
This topic advances the underwater inspection and waterfront infrastructure industries by promoting a shift from reactive to proactive inspection methodologies. By emphasizing the importance of pre-inspection structural understanding and real-time risk assessment, it enhances diver safety, improves inspection accuracy, and reduces the likelihood of catastrophic failures. It also encourages a more integrated approach between engineers, inspectors, and asset owners, fostering a culture of collaboration and informed decision-making that elevates professional standards across the field.
Does the project / topic implement new and innovative techniques, materials, technologies, and delivery methods?
Yes. This approach leverages innovative technologies such as 3D modeling, sonar imaging, and digital twin platforms to visualize and analyze structures before inspection. It also introduces structured decision-making protocols during inspections, including criteria for initiating an “all stop” when critical findings are observed. These innovations not only improve safety and efficiency but also represent a significant evolution in how underwater inspections are planned and executed.
What was the most challenging aspect of your project / topic and how did you handle it to ensure success?
One of the most challenging aspects is the lack of accessible, accurate historical data on many aging waterfront structures. Without original design documents or maintenance records, it is difficult to assess potential risks prior to inspection. To overcome this, developing a hybrid approach that combines available archival research with advanced scanning technologies and engineering inference. This allowsed inspection teamsus to reconstruct probable structural configurations and identify high-risk areas, ensuring inspections could proceed with greater confidence and safety.
