An ESA can help determine if the property has been contaminated by previous or current activities. The ESA can help protect the purchaser of a property from environmental risks prior to the closing on a property.  Lenders ...

  • Case study - Wall leakage testing in the lab with acoustic camera

    Problem Facade insulation testing is usually performed by using a loudspeaker in the sending room, and record the sound pressure level (SPL) with microphones in both the sending and receiving room. The difference in SPL adjusted for the size of the dividing wall element will then give an estimate of the sound reduction quality of that element. However these measurements will not say ...

  • The Importance of Wastewater Force Main Management

    Condition assessment and management of wastewater force mains has historically been challenging for operators. Conventional methods (e.g. visual inspection, sonar and laser profiling) do not provide a comprehensive condition assessment because they do not quantify the loss of structural capacity. As WEFTEC 2013 in Chicago approaches, ...

  • What`s in the numbers? a review and analysis of more than 400 miles of force main inspection and condition assessment data

    Abstract Comprehensive condition assessment of wastewater force mains provides significant challenges to owners/operators of collection systems as the ability to shut down or expose the pipeline for a thorough inspection is often impractical due to operational and/or financial considerations. Traditional gravity sewer inspection techniques (i.e. visual-based technologies) do not always ...

  • 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 ...
