VibraCore

VibraCore offers a comprehensive solution for automated risk assessment of building damage during vibration-intensive construction activities, such as sheet pile or driven pile installation. This tool integrates four key features to ensure a streamlined and accurate assessment process.

1. Impact Force Calculation: VibraCore determines the required impact force of a vibratory hammer for sheet pile installation, using soil classification data, cone resistance, local friction (from CPT Core), and sheet pile properties. The tool calculates the maximum Impact force according to CUR 166 guidelines, providing essential input for subsequent analysis.
2. Vibration Velocity Prediction: VibraCore predicts the maximum vibration velocity at specified distances during installation, following either Prepal or CUR 166 standards. It takes into account nearby building characteristics to compute limit vibration velocity based on SBR A criteria. If the calculated risk of structural damage exceeds acceptable levels, the tool flags the building for further attention.
3. Vibration Nuisance: This feature is focused on evaluating the nuisance caused by different vibration sources. VibraCore calculates the normative velocity distance using SBR-B criteria, considering the function and proximity of nearby buildings as well as the duration of the work. This ensures compliance with Dutch building code and minimizes the potential for vibration nuisance.
4. Noise Assessment: VibraCore also evaluates the environmental impact of noise generated during construction activities. It assesses whether the noise levels fall within acceptable limits based on the "Handleiding meten en rekenen industrielawaai [2004]" guidelines. If the noise exceeds these limits, the tool flags the affected buildings, ensuring comprehensive risk management.

In essence, VibraCore empowers users with an integrated solution for assessing and mitigating the risk of building damage induced by vibration works. By leveraging sophisticated algorithms and industry standards, it enhances efficiency and precision in evaluating potential risks, ultimately contributing to safer construction practices.
