  • Robot Device for Pipe Inspection - Case Study

    In 2005, Pure Technologies (Pure), a provider of various structural monitoring and leak-detection technologies, set about to develop a pipeline assessment tool that could monitor and report on the condition of pre-stressed concrete cylinder pipes (PCCP) utilized in municipal water and sewer systems. The tool’s competitive advantage would be accurate assessment decoupled from the need to ...

  • Valuing information for sewer replacement decisions

    Decision-making for sewer asset management is partially based on intuition and often lacks explicit argumentation, hampering decision transparency and reproducibility. This is not to be preferred in light of public accountability and cost-effectiveness. It is unknown to what extent each decision criterion is appreciated by decision-makers. Further insight into this relative importance improves ...

  • Evaluating the role of deterioration models for condition assessment of sewers

    Ensuring reliable structural condition of sewers is an important criterion for sewer rehabilitation decisions. Deterioration models applied to sewer pipes support the rehabilitation planning by means of prioritising pipes according to their current and predicted structural status. There is a benefit in applying such models if sufficient inspection data for calibration, an appropriate ...

  • Factory Conveyor Inspection

    A plywood manufacturer needed to inspect the roller bearings for its main conveyor motors. This inspection required a shutdown of the entire production line, and every minute of downtime would cost money. Additionally, because the motors were located in hard to reach areas, some several meters high, a portable and lightweight instrument would be needed. The VJ-ADV video borescope from RF System ...
