Unlocking Insights on Piles, Soil Layers, Sinkholes, and Hidden Structures

This presentation will detail various geophysical methods that can be used to assess subsurface conditions in civil infrastructure. This will include methods like pulse echo to determine pile length, seismic refraction to evaluate soil layers and bedrock depths, downhole sonic methods, magnetic gradiometer, tomography and ground penetrating radar. These various methods can be used to determine the length of piles, the thickness and quality of soil layers, along with the presence of seepage indicating the formation of a sinkhole. These methods can also be used to determine the location and extent of buried concrete and steel structures.

This presentation will provide details regarding how these various methods work and provide project histories showcasing how they have been applied to assess civil infrastructure throughout North America.

Unlocking Critical Insights for Reinforced and Prestressed Concrete Pipe Evaluation

Reinforced concrete pipes transport water and wastewater of all types throughout the world.  When these reinforced concrete pipes fail, it can cause major impacts to the public and the operation of critical infrastructure.  Communities can be severely impacted if a water pipe fails, causing a loss of access to clean water. 

Major industrial complexes like power generation rely on reinforced concrete pipes to deliver cooling water.  Without constant cooling, these generation plants are not able to operate.  Agriculture is another major industry that relies heavily on water delivery through reinforced concrete piles.  Without reinforced concrete piles, the world could not operate as it does today.  However, inspection of these pipes is very difficult. 

This presentation will showcase several non-destructive methods that are used to assess the condition of reinforced concrete pipes, both from the external and internal surfaces, including the use of ROV’s.  Through the testing of concrete pipes and determining locations of deterioration, repairs or replacement can be planned prior to failure, which will ensure that water is delivered, and wastewater is carried away as it should.

The Role of Non-Destructive Testing (NDT) in Uncovering Structural Integrity Insights

The safety and durability of bridges are critical concerns for the transportation industry. Non-destructive testing (NDT) methods have been developed and improved to evaluate the structural integrity of bridges. Load rating is one of the most important assessments of bridge safety, and NDT techniques can play a key role in the process.  This presentation will cover the use of NDT to load rate bridges, including the different methods available and their advantages and limitations.

The presentation will discuss the different NDT techniques, including ground penetrating radar, impact echo, pulse velocity and others. Each technique will be explained in detail, including its principles, advantages, and limitations.  The presentation will also discuss the importance of data interpretation and analysis in load rating using NDT techniques. 

This presentation will provide examples of how this is done and the challenges that may arise in the process. NDT methods are essential in load rating bridges. This presentation will provide a comprehensive overview of the different NDT techniques available, their advantages and limitations, and the importance of data interpretation and analysis in load rating using NDT methods.
