Construction Noise and Vibration Assessment

Construction activity can generate significant temporary noise and vibration, particularly on urban sites and developments close to residential properties, businesses, schools and other sensitive locations. Assessing these impacts before works begin helps contractors and developers establish appropriate controls and reduce the risk of complaints or regulatory issues.

Our acoustic consultants provide construction noise and vibration assessment, monitoring and mitigation advice throughout the project lifecycle.

Construction Noise Prediction

We can predict construction noise and vibration associated with proposed works and assess potential effects on surrounding receptors.

The assessment can consider construction plant, demolition, piling, excavation, deliveries and other activities, allowing appropriate controls to be incorporated into the construction programme.

BS 5228 Assessment

Our consultants apply recognised construction noise and vibration guidance, including BS 5228, to assess likely impacts and develop appropriate mitigation measures.

This provides a structured basis for managing noise and vibration during construction and responding to planning or local authority requirements.

Section 61 Applications

Where required, we can provide technical support for Section 61 applications under the Control of Pollution Act 1974. These applications can establish agreed controls for construction noise and vibration before works commence.

Early preparation can help contractors demonstrate that potential impacts have been properly assessed and that suitable mitigation is in place.

Construction Environmental Management Plans

We provide acoustic input into Construction Environmental Management Plans and related construction management documentation.

This can include proposed working methods, monitoring arrangements, mitigation measures, complaint procedures and trigger levels for further investigation.

Construction Noise and Vibration Monitoring

Monitoring can be undertaken during construction to establish actual noise and vibration levels and identify whether agreed limits or management measures are being met.

Where monitoring identifies an issue, our consultants can advise on practical corrective measures to reduce the impact on surrounding properties and sensitive receptors.

Practical Construction Acoustic Management

Effective noise and vibration management should be considered alongside the construction programme rather than treated as a reactive exercise. Early assessment allows contractors to select suitable equipment, working methods and controls while maintaining progress on site.

Question: What is a Construction Noise and Vibration Assessment?

Answer: A Construction Noise and Vibration Assessment predicts the noise and vibration that demolition and construction activities will generate at nearby sensitive receptors, such as homes, schools, hospitals and offices, and identifies measures to control them. It considers the plant and equipment to be used, working hours, the duration of each phase and the distance to receptors.

Assessments are prepared in accordance with BS 5228 Code of Practice for Noise and Vibration Control on Construction and Open Sites and are commonly required by planning conditions, Environmental Impact Assessments and Section 61 applications.

 

Question: When is a Construction Noise and Vibration Assessment required?

Answer: Assessments are typically required for:

  • Major developments and Environmental Impact Assessment schemes
  • Sites close to residential properties, schools or healthcare facilities
  • Demolition, piling and basement excavation
  • Works near listed buildings or sensitive structures
  • Discharge of planning conditions requiring a Construction Management Plan or Construction Environmental Management Plan
  • Section 61 consent applications under the Control of Pollution Act 1974
  • Extended or night-time working

Local authorities use the assessment to set noise limits, working hours and monitoring requirements.

 

Question: What is Section 61 consent?

Answer: Section 61 of the Control of Pollution Act 1974 allows a contractor to apply to the local authority for prior consent for construction works, setting out the methods, plant, hours and noise levels proposed. If consent is granted and its conditions are followed, the local authority cannot serve a Section 60 notice to stop or restrict the works. Section 61 applications are common on major projects in London and other cities and require a detailed BS 5228 assessment.

 

Question: How is construction noise assessed under BS 5228?

Answer: BS 5228 provides sound power data for construction plant and methods to predict noise levels at receptors, accounting for distance, screening, on-time and the number of items operating. Predicted levels are compared with the ABC method thresholds, typically 65, 70 or 75 dB LAeq depending on existing ambient noise, or with a 5 dB change criterion. Where thresholds are exceeded, mitigation or further assessment of significance is required.

 

Question: What are the effects of construction vibration?

Answer: Construction vibration from piling, breaking, compaction and heavy vehicles can cause disturbance to occupants and, at higher levels, cosmetic or structural damage to buildings. Human response is assessed against BS 5228 and BS 6472 criteria using peak particle velocity (PPV) and vibration dose values. Building damage is assessed against BS 7385 thresholds. Assessments identify receptors and structures at risk and recommend methods such as pressed-in piling, vibration monitoring and trigger levels.

 

Question: What mitigation measures reduce construction noise and vibration?

Answer: Best practicable means under BS 5228 include selecting quieter plant and methods, positioning plant away from receptors, acoustic screens and enclosures, restricting hours for the noisiest activities, switching off idle plant, community liaison and monitoring. Noise and vibration monitoring with real-time alerts allows contractors to demonstrate compliance with agreed limits.

 

Question: Why choose Syntegra Group for construction noise and vibration?

Answer: Syntegra Group prepares Construction Noise and Vibration Assessments, Section 61 applications, construction noise management plans and monitoring programmes for developments across the UK. Our acoustic consultants have experience negotiating practical limits and working arrangements with local authority Environmental Health Officers.
