CONSTRUCTION VIBRATION MONITORING

Vibration monitoring plays a key role in protecting surrounding buildings, high valued assets or structures during construction works. We put together a monitoring plan for your project either based on a specification you provide, or information given about your site and the works being carried out. Throughout the monitoring we also provide guidance on methods to remain within regulations throughout the project.


Activities that generate vibration:

  • Demolition of existing structures

  • Excavation Works

  • Piling Works

  • Breaking of Concrete Slabs

  • Heavy Vehicle Movement

  • Construction Works


Structures that vibration can affect:

  • Railway Lines

  • Commercial & Residential Buildings

  • Listed Buildings

  • Water Mains

  • Electrical Sub Stations

  • Gas Mains

  • Hospital Scanners

  • Data Centers


The environmental monitoring systems and solutions we use, offer our clients the peace of mind that the construction works being carried out do not affect the surrounding buildings or structures.  We have a huge and well-supported hire fleet of well maintained modern vibration monitors.


Our Environmental Monitoring Services

Our vibration sensors will measure the levels of vibration to ensure works remain within set parameters and are fully compliant to British Standards BS7385, BS5228, DIN4150-2.  With our vibration sensors being small portable monitors, they are ideal for moving around construction sites if required.


The vibration sensors would be installed on site by a vibration consultant and all monitoring is carried out remotely. Our friendly staff keep you and your team informed by phone, text message or emails with the levels being generated on your site.  Finally, we provide weekly monitoring reports which are sent to your Site Managers at no extra cost.


Alongside vibration monitoring we also provide noise & dust (Air Quality) monitoring services as part of our environmental monitoring package.  Monitoring noise & dust on your site protects the health and wellbeing of your workers and the local community.


Vibration Monitoring Services provide the full environmental monitoring package ensuring our clients meet the requirements of their brief and if you would like to know more about our services please call us today on 0208 108 0440.


What is PPV - Peak Particle Velocity

Ground vibration is measured in terms of Peak Particle Velocity (PPV) with units in mm/s (Millimetres Per Second). It should be noted that the PPV refers to the movement within the ground of molecular particles and not surface movement.

DEMOLITION VIBRATION MONITORING

Requirements for vibration monitoring during demolition works is becoming increasingly common to protect surrounding buildings or sensitive structures from the potential excessive vibration levels during the demolition of large structures and heavy vehicle movement on site. 


To effectively monitor vibration during demolition works it is crucial to carry out a pre-demolition site assessment to identify potential risks, catalogue the condition of nearby structures and determine monitoring locations. 


Local Authorities often require vibration monitoring to be undertaken before work starts on site in order to establish baseline levels. Continuous vibration monitoring can then be required for the duration of the works.

Vibration Monitoring during Demolition - Mitigation measures to be considered:

  1. Utilise low impact demolition methods such as non-percussive plant wherever practicable.
  2. Avoid the transfer of noise and vibration from demolition activities to adjoining occupied buildings through cutting and vibration transmission path or by structural separation of building.
  3. Rather than breaking in-situ, consider the removal of larger sections by lifting them out and breaking them down either in an area away from sensitive receptors or off-site.
  4. Vibratory compaction equipment to be used in a mode which minimises the incident vibration at nearby residential and other sensitive properties. Consideration should be given to engaging concentric weights only when running at speed to avoid run up, run down resonances, the use of smaller equipment, or turning off the mechanical vibration on vibratory rollers and undertaking more passes for areas where there is a particular risk that disruption may occur at neighbouring properties.
  5. Use rotary drills and “bursters” activated by hydraulic or electrical power, or chemically based expansion compounds, to facilitate fragmentation and excavation of hard material.


PILING VIBRATION MONITORING

Piles are used to support many types of structures such as buildings and bridges, this activity create vibration in the ground which may affect properties. The amount of vibration caused depends on the weight of the ramming equipment, impact velocity, impact duration, shape of the pile and the surrounding soil.


Vibration Monitoring is an excellent tool to monitor the levels generated from such works on the surrounding structures and we can keep Site Managers informed of the levels their works are creating so that they can assess and adjust works to keep vibration levels from reaching critical levels which could be affecting neighboring properties and occupants.


What is Ground-borne Vibration

Ground-borne vibration is propagated in wave-form in the ground and can be transmitted into foundations of nearby buildings. This causes vibration in the building that can be felt by the people in it. Also, audible sound waves may be produced be resonance generated in walls and ceilings.


Our Piling Monitoring Services

Vibration Monitoring Services offer continuous monitoring during piling works, helping to keep vibration damage to surrounding buildings and structures to a minimum using the most up to date monitoring equipment.  


We offer a cost effective & convenient service throughout the works including:

  • Baseline Monitoring
  • Beacons available if visible alarm alert needed
  • Continuous Long-Term Monitoring
  • Dedicated Officer Monitoring the levels on your site
  • Liaison with Site Manager via Phone Call/Text Messages/Emails
  • Real time data available via an online portal
  • Text & Email alert alarms will be provided
  • Flexible site visits, to suit the Contractor
  • Detailed reporting provided every week of monitoring
  • Working within the Local Authorities specification (BS7385, BS5228 & DIN4150-2)
  • Convenient, Secure Positions, Agreed with Contractor
  • Monitors come with battery packs that have 3 months battery life

Vibration Monitoring Services monitor vibration caused by piling works on sites remotely, with pre-set alarm levels programmed into the unit, our friendly staff can then keep your Site Manager informed by phone, text message or emails with the levels the works are generating on site.


With years of experience in this sector and working closely with piling contractors, Vibration Monitoring Services can offer the full vibration monitoring package to help you meet your clients brief.
