Smoke Shafts & Air Tightness Test

Smoke Shafts & Air Tightness Test

Top 10 Ways to Prepare Your Smoke Shaft for an Air Tightness Test

Ensuring the safety and compliance of smoke shafts in buildings is a critical aspect of fire safety. Conducting an air tightness test on smoke shafts is essential to confirm their effectiveness in preventing the spread of smoke and fire.

Here are the top 10 ways to prepare smoke shafts for the test:

  1. Consult with the Smoke Shaft Experts: Early consultation with air tightness consultants, that specialise in smoke shaft testing, can provide valuable insights into effective smoke shaft design and sealing strategies.
  2. Set Airtightness Targets: Determine the required airtightness level, typically less than 3.8 m³/h/m² @ 50 Pa, and design your smoke shaft to meet this target; however, however some smoke shafts require different targets, so it’s always best to check.
  3. Use Robust Construction Materials: Ensure the construction materials are robust enough to provide a tight air barrier, such as concrete walls or high-density blocks.
  4. Seal Internal Finishes: Treat the inside of the shaft as the primary air seal line. Ensure the finish is smooth and sealed at all junctions and joints, especially where steels etc. penetrate through the shaft envelope.
  5. Seal Service Penetrations: Carefully seal all service penetrations, structural penetrations, and cable penetrations to the smoke shaft envelope.
  6. Seal Door Openings: Ensure all doors within the smoke shaft are fully sealed with heavy-duty materials.
  7. Seal AOV Door Frames: The perimeter of the AOV doors should be mastic sealed to the shaft.
  8. Seal Base and Head of Shaft: Carefully seal the base and head of the shaft prior to the air test.
  9. Use Proper Testing Equipment: Use a UKAS calibrated blower door fan set to pressurize the shaft and measure the air tightness.
  10. Address Test Failures: If the shaft fails to meet the air leakage target, use smoke testing and/or thermal imaging to identify and seal leaks.

By following these steps, you can ensure your smoke shaft is well-prepared for the air tightness test, enhancing building safety and compliance inline with latest building regulations.

Preparing for a BREEAM Thermal Imaging Survey

To ensure accurate and effective results, a few steps must be taken before the survey:

  1. Provide Building Drawings – We require a full set of elevation, roof, and floor plan drawings before the site visit.
  2. Heating & AC Setup – The building’s heating or air conditioning system must be turned on at least 12 hours before the inspection to create a minimum 10°C temperature difference between the interior and exterior.
  3. Dry & Stable Conditions – Surfaces must be dry and free from solar loading (i.e., no sunlight warming external surfaces before testing).
  4. Clear Surroundings – Remove any materials stacked against the building envelope, such as timber sheeting.
  5. Time the Survey Right – To prevent interference from solar gain, we typically start the survey one hour before sunrise. This may require an early morning visit, so a responsible site contact should be available.
  6. Provide Safe Access – The site representative must ensure safe access to all areas, including roofs and elevated sections. If necessary, the client must supply a cherry picker and a certified operator.
  7. Control Internal & External OpeningsInternal doors should remain open to maintain uniform internal temperatures, while external doors and windows must be closed to prevent heat loss.
  8. Site Safety Briefing – Our engineer must receive a site-specific risk briefing from a competent person.
  9. Obtain Permits to Work – Any necessary permits must be secured before fieldwork begins.

Indoor Air Quality Testing

Indoor Air Quality Testing

Indoor Air Quality Testing and the Construction Industry
In recent years, the importance of indoor air quality (IAQ) has gained significant attention, and for good reason. As we spend a substantial amount of time indoors, whether it be at home, work, or other indoor spaces, the quality of the air we breathe can have a profound impact on our health and well-being. This is particularly relevant to the construction industry, where IAQ testing plays a crucial role in ensuring safe and healthy environments for workers and occupants alike.

During the construction process, various materials, such as paints, adhesives, solvents, and building products, are used extensively. While these materials are essential for building construction and renovation, they can release harmful pollutants into the air, potentially causing health issues if not managed properly. Indoor Air Quality testing in the construction industry aims to identify and mitigate these risks, creating healthier and safer indoor environments.

So, what exactly is IAQ testing, and how does it relate to the construction industry? IAQ testing involves the assessment of indoor air to determine the presence of pollutants, including volatile organic compounds (VOCs), formaldehyde, particulate matter, mold, and other potential contaminants. It typically involves a combination of sampling, monitoring, and analysis to evaluate air quality parameters, such as temperature, humidity, carbon dioxide levels, and specific pollutants.

In the construction industry, IAQ testing serves multiple purposes:

1️⃣ Compliance with Regulations: Construction projects must adhere to building codes, regulations, and standards established by local, state, and federal authorities. Many jurisdictions now require IAQ assessments to ensure that new buildings or renovations meet minimum air quality requirements. By conducting IAQ testing, construction companies can demonstrate compliance and avoid potential legal and health-related issues.

2️⃣ Worker Safety: Construction workers are exposed to various hasardous substances and conditions on a daily basis. Poor IAQ can exacerbate these risks, leading to respiratory problems, allergies, headaches, fatigue, and other health concerns. Regular IAQ testing allows construction companies to identify and address potential hasards, implementing appropriate control measures to protect workers’ health and well-being.

3️⃣ Occupant Health and Comfort: Once a construction project is completed, buildings are occupied by individuals who expect a safe and healthy environment. Poor IAQ can contribute to “sick building syndrome,” where occupants experience symptoms like coughing, sneesing, eye irritation, and fatigue. IAQ testing during and after construction helps ensure that the building’s indoor environment meets acceptable standards, promoting the well-being and comfort of its occupants.

4️⃣ Reputation and Customer Satisfaction: In an increasingly environmentally conscious world, people are becoming more aware of the importance of IAQ and its impact on their health. Construction companies that prioritise IAQ testing demonstrate a commitment to the well-being of their workers and the future occupants of the buildings they construct. Such proactive measures not only enhance their reputation but also contribute to customer satisfaction and overall project success.

To effectively address IAQ concerns in the construction industry, it is crucial for companies to incorporate IAQ testing into their project planning and execution. This includes engaging IAQ professionals who can conduct comprehensive assessments, provide guidance on best practices, and assist in implementing appropriate ventilation systems and pollutant control measures.

5️⃣ Green Building Certifications: Many construction projects strive to achieve green building certifications like LEED (Leadership in Energy and Environmental Design) or WELL Building Standard. These certifications place a strong emphasis on IAQ and require comprehensive testing and monitoring throughout the construction process. By conducting IAQ testing, construction companies can meet the criteria for these certifications, enhancing the marketability and sustainability of their projects.

6️⃣ Building Performance Optimisation: IAQ testing is not limited to new construction. Existing buildings can also benefit from testing to identify and rectify potential IAQ issues. Construction companies involved in renovation and retrofitting projects can conduct IAQ assessments to improve the performance of older buildings, enhancing energy efficiency, occupant comfort, and overall air quality.

7️⃣ Preventing Mold and Moisture Issues: Construction sites are susceptible to moisture intrusion, which can lead to mold growth if left unaddressed. Mold not only affects IAQ but also poses a serious health risk to occupants. IAQ testing can help identify areas of moisture buildup, enabling construction companies to take preventive measures and ensure proper ventilation and drying techniques are in place, thereby mitigating the risk of mold formation.

8️⃣ Long-Term Cost Savings: Investing in IAQ testing during construction can yield long-term cost savings for building owners and occupants. By identifying and rectifying IAQ issues early on, construction companies can prevent costly remediation efforts down the line. Additionally, optimising ventilation systems and controlling pollutant sources can result in energy savings and reduced operational costs for building owners.

9️⃣ Collaboration with HVAC Professionals: Indoor air quality is intricately linked to heating, ventilation, and air conditioning (HVAC) systems. Collaboration between construction companies and HVAC professionals is essential to ensure proper design, installation, and maintenance of HVAC systems that promote good IAQ. By working together, construction companies can ensure that the building’s ventilation system meets industry standards and effectively removes contaminants from the indoor environment.

Indoor air quality testing is not merely an optional add-on in the construction industry but a vital component for creating safe, healthy, and sustainable indoor environments. By integrating IAQ testing into construction projects, companies can demonstrate their commitment to worker safety, occupant health, regulatory compliance, and environmental responsibility.

Ultimately, prioritising IAQ testing contributes to the overall success, reputation, and longevity of the construction industry in an era where indoor environmental quality is gaining increasing attention and significance.

Sound Insulation Testing

Sound Insulation Testing

Soundproofing & Sound Insulation Testing

Adequately soundproofing your project to ensure you pass your sound insulation testing and meet the requirements of Approved Document Part E, should not be seen as pain. Achieving good soundproofing between dwellings such as houses and flats is incredibly important for our cities.

Residents don’t want to hear their neighbours through a poorly soundproofed party wall or floor. Currently, poor Sound Insulation is an issue that plagues many types of developments. This is accentuated if you have a noise neighbour who may like to play loud music, drum kits or simply enjoy tap dancing on the floor above your poorly soundproofed property.

Basics of Sound Proofing

Sound Insulation Testing
Most home owners may not understand the importance of Sound Insulation Testing to show compliance with the Part E of Building Regulations. When developers undertake the acoustic design and construction to their projects, they should be aiming for more than just a marginal pass; it should be about trying to attain a sound insulation performance of 55dB for airborne sound and 52dB for impact sound.

If developers design their projects to attain the aforementioned sound insulation values, they will reap the benefits in the long run. If they rent the blocks, their clients renting the dwellings will be less likely to leave due to noise issues.  Another plus is they will not have to deal with noise complaints on a weekly basis which can be stressful for both the resident and the development team. 

Having undertaken hundreds of design reviews for architects, developers and builders we know the challenges behind soundproofing new and converted developments. However complicated the construction, we try to find a solution to improve the sound insulation and help you pass your sound insulation test.

Firstly we look at the four basic principles of soundproofing

Ensuring Adequate Mass

One of the key ways to improve the sound insulation of a party floor or wall is to ensure there is adequate mass, this can be done by using one of the high mass acoustic mineral wool products. Using sound board (15mm) will help to ensure your plasterboard lining/s have the optimum mass to pass. It is very difficult to achieve the requirements of Approved Document E when using standard 12.5mm plasterboard on your wall and/or ceilings. If extra linings such as plywood, OSB, and cement board are introduced it makes the walls heavy and a lot more rigid, meaning the vibrations will be reduced

Decoupling Materials

All too often, residents can hear their neighbours walking across the floor in the apartment above them. This is particularly noticeable in if the apartment above has a marble tile and/or or a hardwood finish. When the units have this type of finish, it is essential that the floor partition has an acoustically robust construction

There are many ways to reduce the sound of footfall noise from the flat above, the best way is to introduce is decoupling to the ceiling structure to make it separate from the floor joists.  This can be done incorporating a Resilient Bar System, A suspended MF Ceiling or Independent Ceiling and/or a Genie Clip System. All these systems should decouple the soundboard lining from the joists above.

To improve further on the above upgrade/s you can also add a good quality acoustic mineral wool between the joists, studwork or ceiling void.  This needs to be tightly fitted between the framework to ensure good material coverage ‘so it doesn’t have any gaps or voids. You can also upgrade party walls; by using the systems mentioned above, as it will help to reduce the intensity and spread of sound waves and vibration through the party wall and should help you pass your sound insulation test.

In our experience the best results are usually attained by constructing a twin wall consisting of two layers of studwork, with a high density acoustic mineral wool between each stud wall with two layers of soundboard either-side.

We offer a total acoustic package consisting of acoustic consultancy and sound insulation testing; with a practical and costs effective approach from start to finish.

Ensure an Air Tight Construction

You can greatly improve your sound insulation performance by the introduction of an air tight seal. If there is any air leakage paths, gaps or holes sound will find a way through. Inadequate air sealing is one of the most common reasons for Sound insulation Test Failures. Luckily, it’s also one of the easiest things to improve.

Introduce Damping to your Construction

If you introduce damping to your party wall and ceilings it can help to reduce the vibrations through the construction caused by sound waves. Previously we have advised clients to use Tecsound between the plasterboard layers to great effect.

Damping materials such as Tecsound can be applied almost all types of party wall and floor construction where two layers of plasterboard board are being installed. When combined with genie clips, this can be a quick and effective way to upgrade your acoustic construction on site.

ISO Standard 14644-1: 1999 has recently been updated to the 2015 version. It requires changes to sampling procedures and monitoring plans for cleanrooms and clean zones, all of which is outlined in the revised ISO 14644-1:2015 standard. Organisations will be required to redefine their validation sampling plans and data evaluation and will obviously affect the clean room testing reportage.

The updated ISO 14644-1:2015, specifies the classification of air cleanliness in terms of concentration of airborne particles in cleanrooms and clean zones and is the first significant revision since its original release in 1999.

The major change from ISO 14644-1:1999 publication is the adoption of a more consistent statistical approach to the selection and number of sampling locations; and thereafter the evaluation of the data collected. 

This new approach allows each location to be treated independently with at least a 95 % level of confidence that at least 90 % of the cleanroom or clean zone areas will comply with the maximum particle concentration limit for the target class of air cleanliness.

Cleanroom users will have to make changes to the cleanroom validation procedures to meet the requirements laid out in the latest version of ISO 14644-1:2015 and ISO 14644-2:2015.  It is possible that the revised standard will require cleanroom owners to make changes to their cleanroom to ensure they continue to achieve the required classification and remain compliant.

UKAS Accredited Sound Testing

UKAS Accredited Sound Testing

UKAS Accredited Sound Testing

The need to carry out sound insulation testing to assess and report the acoustic performance of dividing partitions between dwellings has become increasingly important in order to demonstrate that a building’s intended performance is achieved when constructed.

Poor design detailing and/or onsite construction can have a significant impact on the overall performance of building elements and the building as a whole. Post completion sound testing provides greater certainty that designed performances are actually being achieved in compliance with Approved Document E.

UKAS Accredited Sound Testing

Pre-completion Sound Testing is now an integral part of supporting the completion certificate process throughout the UK and Ireland. In order to ensure that testing is undertaken within a robust regime which controls the reliability of test results, government guidance is in place which describes restrictions on those who should carry out sound testing and reportage.

Approved Document E states a set of sound tests should be carried out for every ten dwellings (houses, flats or rooms for residential purposes). However, if the development has several different construction types, you may need to carry out further tests for each type of construction.

For houses this usually means you are required to undertake 2 airborne wall sound tests (up to 10 houses) to the dividing walls. For flats you will be usually be required to undertake 2 airborne wall, 2 airborne floor and 2 impact floor tests (up to 10 Flats). When we undertake a fee proposal for clients, we always include a full testing schedule so it can be submitted to building control for their approval prior to the test date.  

One of the stipulations of Approved Document E is that the testing company needs to be UKAS accredited, this is covered under the Resistance to the passage of sound: Approved Document E [ADE] it goes on to state that “The person carrying out the building work should arrange for sound insulation testing to be carried out by a test body with appropriate third party accreditation” and is downloadable at: https://www.gov.uk/government/publications/resistance-to-sound-approved-document-e.

APT Sound Testing is UKAS accredited to carry out sound insulation testing and is laboratory and as a result our reports will be accepted by building control – here is a link to our UKAS Sound Testing Accreditation: https://www.ukas.com/wp-content/uploads/schedule_uploads/00002/4340Testing%20Multiple.pdf

For future note we are also UKAS accredited to carry out Air Tightness Testing – here is a link to our UKAS Air Tightness Accreditation: https://www.ukas.com/wp-content/uploads/schedule_uploads/00002/4340Testing%20Multiple.pdf

Noise Assessments & APT Sound Testing

Noise Assessments & APT Sound Testing

Overview of Noise Assessments & APT Sound Testing

APT Sound Testing focuses on noise tests that help meet planning rules for different projects. With a lot of experience, we carry out noise surveys following BS8233 and BS4142 guidelines. We handle noise problems for both homes and industries. If you are planning new homes like apartments or hotels or if you need to look at industrial noise from machines on old sites, our team offers careful checks that fit your needs.

Here, we’ll explain each kind of noise survey and what it does. This will help you decide which option might be right for your project.

BS8233 Noise Survey for Residential Developments

A BS8233 noise survey is usually needed for new homes, like apartments, houses, or hotels. These surveys look at how outside noise can impact future residents. They help local authorities understand the noise around the area and suggest ways to reduce it. These surveys are often asked for during the planning stage. BS8233 noise assessments help predict how noise from traffic, entertainment, or nearby industries might influence a new residential site.

In the UK, the National Planning Policy Framework says that new homes must offer a good level of sound comfort. This rule helps keep noise away from people. It includes things like soundproofing walls and putting up barriers outside. The goal is to keep both the inside of homes and outdoor places, like gardens, peaceful.

APT Sound Testing has completed many BS8233 noise assessments for different residential projects, including single homes and large apartment buildings. We team up with planning consultants, architects, builders, and private clients to make affordable noise solutions during the design phase. By spotting noise problems early, we help add noise reduction measures into the design. This prevents expensive fixes later and reduces noise impact on future residents.

In these surveys, our team checks noise levels to make sure they are okay. This often means taking readings at different times of the day, looking at noise both inside and outside the building. We then create recommendations for the project, focusing on certain noise sources. This could include using soundproof materials in the building or noise barriers around outdoor areas. Our aim is to make sure the development meets local rules while keeping a comfy space for people living there.

For clients who need a BS8233 noise survey, our team is here to talk about the details. We can show you how our checks can help your planning application go smoothly. Contact us at 01525 303905 or email us at info@aptsoundtesting.co.uk for more details.

BS4142 Noise Survey for Industrial Sites

BS4142 noise surveys are important for measuring noise from industries in places where homes and factories are close together. These surveys are often needed when new loud machines are added to a site. They are also necessary when noise from industries might bother nearby houses or other quiet places. As the government supports development on old industrial land, finding a balance between industry work and people’s comfort at home is more important than ever.

Noise from factories can greatly affect nearby areas. Because of this, local planners often set strict rules on how much noise can be made. It is important for machines and equipment to keep noise within allowed levels, especially at the edges next to homes. Our BS4142 surveys aim to measure how much noise these industrial sources make. We check if the noise levels meet the rules set by authorities.

To do a BS4142 noise assessment, we check the normal noise levels in the area. We do this with and without the noise source running, usually over 24 hours. This method helps us see how much the industrial noise affects the area and if it goes over local noise limits. Our skilled consultants use LA90, which is an important way to measure background sound. This shows the noise level that is too loud for 90% of the time we measure it. This helps us understand the noise in the area well.

Once we finish our measurements, we write a detailed report. This report includes noise maps to show how well we can reduce noise. If noise reduction is needed, we can suggest ways to lower the noise. This can include sound barriers, covering machines, or changes to buildings to keep noise inside. Our BS4142 checks look at different sources of industrial noise. This includes systems that take air out, air conditioning units, refrigeration tools, and regular noise from factories.

With a complete noise check, we help developers meet local rules. This makes sure that the project follows noise plans. If you have asked for a BS4142 noise survey, we can help you understand the process and the steps you need to take.

Comprehensive Noise Survey Planning

Comprehensive Noise Survey Planning

Noise Survey Planning for Development Applications

APT Sound Testing offers extensive expertise in conducting noise survey planning assessments for various development projects, addressing both residential and industrial noise issues to ensure compliance with local planning regulations. Our acoustic services include the BS8233 Noise Assessment for reducing noise in residential buildings and the BS4142 Industrial Noise Survey, assessing industrial noise impacts. These assessments play a crucial role in securing planning approvals by ensuring that proposed developments adhere to noise management standards.

BS8233 Noise Survey for Residential Developments

Noise assessments, such as the BS8233 survey, are commonly required for new residential developments, including apartments, houses, and hotels. Local authorities often impose noise-related planning conditions to evaluate potential noise impacts from a proposed project, especially for high-traffic areas or urban developments.

Residential buildings can be affected by various noise sources, such as traffic, industrial operations, and entertainment venues. The BS8233 noise survey seeks to address these potential disruptions by providing detailed analyses on noise levels within residential developments. Our team has performed hundreds of successful noise assessments for residential projects, helping planning consultants, architects, developers, and private clients implement cost-effective acoustic solutions at the design stage. Projects we support vary widely, from small residential buildings to large apartment complexes.

A BS8233 survey becomes essential when seeking full planning permission for residential projects. The survey includes a comprehensive acoustic assessment and noise survey of the development site. This step ensures the property will offer acceptable noise levels and create a healthy living environment for residents. This process aligns with the National Planning Policy Framework (NPPF) in England and Wales, which mandates suitable acoustic conditions for new residential developments. The goal is to establish appropriate noise barriers, such as sound-insulating building envelopes or external noise reduction measures like acoustic fences, to protect both interior and exterior spaces within residential zones.

For further details, our BS8233 Noise Surveys page provides additional insights into these services.

BS4142 Noise Survey for Industrial and Commercial Projects

If an industrial or commercial development involves introducing new noise sources or requires assessing existing industrial noise, a BS4142 noise survey may be required by planning authorities. Industrial noise assessments are increasingly necessary as residential and industrial sites grow closer, especially with the push for redeveloping brownfield areas. With expanding urban growth, residential buildings are often developed adjacent to industrial zones, raising concerns about noise impact on residents’ quality of life and general amenity.

Planning authorities often regulate noise emissions through planning conditions, which can involve restrictions on industrial noise levels and operating hours. Ensuring compliance with these requirements might involve insulating machinery or plant installations to maintain acceptable sound levels at property boundaries or nearby residences. A thorough BS4142 noise assessment outlines the noise levels allowed at the development site and details the measures needed to comply with these standards.

For a BS4142 survey, we measure current sound levels over a 24-hour period to establish a baseline and then evaluate potential new noise impacts by simulating the introduction of planned noise sources. In cases where new noise sources already exist, we measure ambient sound levels both with and without the noise source active to determine its impact. This process uses the LA90 metric, which captures the background sound level that is exceeded 90% of the time during the assessment period.

Our specialist team have extensive knowledge of BS4142 requirements, making them well-suited to perform accurate and comprehensive assessments.

APT Sound Testing’s BS4142 noise assessment report includes a detailed summary of findings and suggested mitigation measures where needed. Our team can provide noise mapping to illustrate how these measures impact the development’s noise environment. The report’s recommendations cover a range of potential noise sources, such as HVAC systems, industrial machinery, refrigeration equipment, and the general operation of industrial facilities.

For clients required to undergo a BS4142 Noise Assessment, we encourage direct contact at 01525 303905 or via email at info@aptsoundtesting.co.uk. More information on these services is available on our BS4142 Noise Survey page.

The Importance of Noise Surveys in Urban Development

Both BS8233 and BS4142 noise surveys are integral to urban planning and development. These assessments ensure that developments meet the dual objectives of supporting growth while safeguarding the welfare and comfort of residents. By addressing noise issues at the planning stage, developers can implement suitable design and acoustic measures, avoiding potential future conflicts with local authorities or resident complaints.

Noise surveys are particularly important in today’s urban landscape, where mixed-use developments are on the rise, and housing, retail, and industrial functions often occupy neighboring areas. Proper planning can prevent sound pollution from becoming a persistent issue and promote harmonious coexistence between various land uses. With the National Planning Policy Framework advocating sustainable and resilient communities, noise management is more relevant than ever in the construction and planning sectors.

APT Sound Testing is committed to supporting clients through every stage of their development projects, from initial noise assessment to the implementation of acoustic solutions. Our experience with both BS8233 and BS4142 noise assessments ensures our clients can confidently meet regulatory requirements and maintain the highest standards of noise management across residential and industrial developments alike.
