Anodes are critical component of cathodic protection systems. As part of this effort, three different anodes were tested in a cathodic protection system that was designed and constructed to prevent further corrosion of reinforced concrete. This anodic system includes an electrically conductive coating composition applied in fluid form over an outer surface of the concrete mix. The composition f...

Predicting the condition of sewer pipes plays a vital role in formulation predictive maintenance strategies to ensure efficient renewal pipes. This study explores potential application ten machine learning (ML) algorithms predict pipe conditions Ålesund, Norway. Ten physical factors (age, diameter, depth, slope, length, type, material, network form, and connection type) environmental (rainfall,...

This paper demonstrates the successful autonomous classification of rotary laser scanner data retrieved by an autonomous robot traversing a sewer pipe system. Rotary laser scanner serve dual purposes of fault detection and navigation. The present aim was to devise a robust landmark detection method for use in the robot’s navigation system. A standard feed forward neural network with 6 hidden ne...

The role of sewer lines as preferential pathways for vapor intrusion is poorly understood. Although the importance of sewer lines for volatile organic compound (VOC) transport has been documented at a small number of sites with vapor intrusion, sewer lines are not routinely sampled during most vapor intrusion investigations. We have used a tracer study and VOC concentration measurements to eval...
