How to Select Vibrating System for Concrete Consolidation
Selection of Internal Vibrators Internal vibrators consolidate by a vibrating head which is inserted into fresh concrete. The number of vibrations per minute (frequency) and the deviation of the head from the neutral position as it oscillates (amplitude) describe the vibration motion.

Vibration Risks in Construction The Constructor
Vibrations due to construction activities can pose significant risks at construction sites. Vibrations can cause health and safety hazards for workers on site, damage to equipment, and impact workmanship or product quality. Understanding these risks is crucial for business owners in order to protect themselves from potential lawsuits and fines.

The Impact of Construction Vibration on Adjacent J.S.
Construction vibrations are a known nuisance and can damage existing structures if they are not properly monitored and accounted for. As a proactive means to mitigate vibration damage claims, nearby buildings should be inspected prior to and after construction and monitored during construction.

A pre-construction survey should document the condition of the structure and all existing cracks in order to determine whether any new cracks appeared during construction. Vibration levels can be monitored during construction with a seismograph to determine if the vibration levels exceeded the building damage threshold.
