Key Processes and Procedures.

Cladding remediation on high-rise buildings is a crucial process aimed at addressing safety and performance concerns related to building facades, particularly in light of risks such as fire hazards or weather damage. The process generally involves several key steps, which are detailed below:

1. Assessment and Inspection

• Initial Inspection: A detailed survey is conducted to evaluate the current state of the cladding system. This includes assessing the material, installation, condition, and compliance with safety standards (e.g., fire resistance).

• Risk Assessment: Specialised professionals (e.g., fire safety engineers or structural engineers) perform risk assessments, which may include fire safety evaluations or structural integrity testing.

• Testing: Material testing, such as checking the fire rating of cladding materials, is often conducted to identify whether the existing cladding meets regulatory requirements and industry standards.

2. Design of Remediation Strategy

• Identify Issues: Based on the inspection and risk assessment, the specific issues are identified (e.g., use of combustible materials, inadequate fire stops, poor thermal performance or a combination of all.).

• Remediation Options: Different remediation options are considered, which might include some or all of the following:

• Replacing or upgrading the cladding materials with fire-resistant alternatives.

• Installing fire barriers or fire-resistant insulation.

• Enhancing the structural anchoring of cladding elements.

• Modifying the ventilation or drainage systems to reduce moisture buildup and prevent water ingress.

• Improving external building access for maintenance and emergency evacuation.

3. Planning and Approvals

• Consultation with Authorities: Building owners and contractors must liaise with local authorities to ensure that any proposed remediation work complies with building codes, safety regulations, and permits.

• Stakeholder Communication: Engaging with tenants, residents, or occupants about the planned remediation work, including potential disruptions and safety considerations, is essential.

• Detailed Estimate and Project Plan: A comprehensive tender and full cost estimate will be prepared for the client. Upon agreed works, a project plan is developed that includes construction timelines, method statements, safety protocols, and logistical considerations.

4. Execution of Remediation Works

• Scaffolding and Safety Measures: Installation of scaffolding or temporary safety barriers to ensure safe access for workers and prevent risks to the public.

• Removal of Defective Cladding: In many cases, the existing cladding is removed, especially if it is found to be non-compliant with safety regulations.

• Installation of New Cladding: New materials, such as non-combustible panels or fire-rated insulation, are installed, and any structural modifications (e.g., reinforcement) are made as required.

• Testing of Systems: Systems such as fire barriers, thermal performance, and weatherproofing are fully tested to ensure they meet the required standards.

5. Final Inspection and Certification

• Post-Remediation Inspection: Once the remediation work is complete, a thorough inspection is conducted to verify that the work complies with building regulations and safety standards.

• Certification: Once the building meets the necessary standards, a completion certificate or safety clearance is issued by the relevant authorities. An EWS1 form will also be issued to the building owner to satisfy lenders that an external wall system has been assessed by a suitable expert as compliant.

6. Ongoing Monitoring and Maintenance

• Routine Inspections: After remediation, periodic inspections are recommended to ensure the cladding continues to perform adequately and remains compliant with safety standards.

• Long-Term Maintenance Plan: A maintenance plan should be established, addressing periodic checks for signs of wear and tear, water ingress, or any other issues that may affect the cladding system’s performance.

The key impacts of the 2022 updates

Regulations:

In the UK, there are several regulations and standards in place to regulate the construction of buildings.

Building Regulations 2010

In the cladding world we follow Building Regulations 2010 which is a set of regulations in England and Wales that govern the construction and alteration of buildings. They are enforced by local authorities and aim to ensure that buildings are safe, energy efficient, and accessible. The regulations apply to most building work, including new builds, extensions, major renovations and remediation work. They cover a wide range of topics including structure, fire safety, ventilation, drainage, energy efficiency, and accessibility.

Building Regulations 2010 is regularly updated to reflect changes in technology, construction methods, and best practices. It is important for building owners, developers, and contractors to be aware of the regulations and ensure that their projects comply with them. Failure to comply with the Building Regulations can result in enforcement action, including fines and the requirement to correct any non-compliant work.

T&T Facades & T&T Cladding Remediation employ in-house experts whose role it is to continually monitor any updates in regulations and policies to ensure all projects we are involved in comply 100% to the current regulations and guidelines.

A key component of Building Regulations 2010, pertinent to cladding contractors and those involved in the design, supply and installation of a building's external wall is Approved Document B.

Approved Document B

This is a document that provides guidance on fire safety regulations in buildings in England and Wales. It is published by the UK government's Ministry of Housing, Communities and Local Government (MHCLG) and is part of the Building Regulations.

The document is divided into two volumes, Volume 1 and Volume 2. Volume 1 deals with residential dwellings, while Volume 2 deals with buildings other than residential dwellings. The document sets out the minimum requirements for fire safety that must be met in these buildings to comply with the Building Regulations.

Key topics covered in relation to cladding include:

Structural fire protection: This section covers the fire resistance of building elements such as walls, floors, and ceilings.

External fire spread: This section covers the prevention of external fire spread, such as through the use of fire-resistant cladding materials.

Amendments to Approved Document B – 1 ^st December 2022

The Government released amendments to Approved Document B which came into force on 1st December 2022.

Main changes, pertinent to external walls:

o A blanket ban of combustible materials in and on the external walls of buildings: Consequential amendments following the laying of the Building (Amendment) (England) Regulations 2022. Prior to this the preferred method of demonstrating compliance was via a fire test carried out in accordance with BS8414. The test was to be carried out by an independent UKAS accredited testing body.

o ACM with an unmodified polyethylene core has been banned from use on all buildings.

o The inclusion of Hotels in the definition of relevant buildings with regards to Regulation 7(2), this means hotels over 18m in height will have to be constructed with external walls materials attaining A2s1d0 or better.

o The exemptions to Regulation 7(2), contained in Regulation 7(3), have been clarified to overcome issues with roof junctions to external walls, the transition from exempt below ground walls to the controlled above ground external wall giving a 300mm zone to affect the transition and the installation of fibre optics.

The updates offered a transition period of six months, meaning to not be controlled by the amendments you will have needed to make your building regulation application before that date and commence on site prior to 1st June 2023.

Regulation 7

Regulation 7 is a section of the UK's Regulatory Reform (Fire Safety) Order 2005 that specifically relates to fire safety in buildings.

When planning a cladding project, it's essential to ensure that the chosen cladding system meets the requirements of regulation 7 as well as the required fire rating for the building's height and intended use. This is particularly important for high-rise buildings, where fire can spread quickly through the building and cause significant damage and loss of life.

Regulation 7 requires that the responsible person (usually the building owner or employer) appoints one or more competent persons to assist in undertaking the preventive and protective measures necessary to comply with the Order.

The competent person(s) appointed under Regulation 7 must have sufficient training, experience, and knowledge to assist in ensuring that the building is safe from the risk of fire. They must also have the authority to implement and maintain fire safety measures, as well as the ability to identify and assess the fire risks in the building.

Overall, Regulation 7 plays an important role in ensuring that fire safety measures are effectively implemented and maintained in buildings to reduce the risk of fire and protect the safety of occupants.

For anyone embarking on a cladding project it pays to consult a specialist cladding contractor such as T&T Facades / T&T Cladding Remediation with the knowledge and expertise to ensure compliance.

4. DO I NEED PLANNING PERMISSION TO CHANGE THE CLADDING ON MY PROPERTY?

In most cases, you will not need planning permission to change the cladding on your property. However, you may need to obtain building regulations approval from your local building control authority or approved inspector.

Planning permission is typically only required for changes that significantly alter the appearance of a building or its surroundings. This may include changes to the size, shape, or design of a building, or alterations to the use of the building. However, the rules and regulations regarding planning permission can vary depending on your location, so it is always best to check with your local planning authority to confirm whether you need planning permission or not.

Building regulations approval, on the other hand, is required for all building work to ensure that it meets the necessary safety and construction standards. This includes changes to the cladding of a building, particularly if the work involves structural alterations or changes that could impact the safety of the building or its occupants. Building regulations are enforced by your local building control authority, and it is essential to obtain approval before starting any building work.

It is important to note that the rules and regulations regarding planning permission and building regulations can be complex, and it is always recommended to seek professional advice before undertaking any building work. A licensed contractor or architect can help you navigate the requirements and ensure that your project is compliant with all relevant regulations.

5. CAN I GET FUNDING TO RECLAD MY PROPERTY?

Yes, there may be funding options available to help you reclad your property. The availability of funding and the specific programmes that are available will depend on your location, the type of property you own, and the reason for the recladding work.

In many cases, government grants, loans, or subsidies may be available to property owners who need to undertake recladding work for safety or energy efficiency reasons such as the Building Safety Fund (see below). These programmes may be offered by local or national government agencies, and eligibility criteria will vary depending on the specific programme.

Another funding option is through financing or loans from banks, building societies, or other financial institutions. Some lenders offer home improvement loans or mortgages that can be used to finance home renovation projects, including recladding work.

It is also worth considering any insurance coverage you may have. If your recladding work is due to damage caused by an insured event, such as a storm or fire, your insurance policy may cover some or all of the costs.

It is important to do your research and explore all of the available funding options to determine the best option for your specific situation. Additionally, be sure to thoroughly review the terms and conditions of any financing or funding before making a commitment.

6. WHAT IS THE BUILDING SAFETY FUND?

The Government Building Safety Fund is a funding programme set up by the UK government to help fund the removal and replacement of unsafe cladding systems on high-rise residential buildings (over 18 meters or six stories in height). The fund was established in May 2020 in response to concerns about the safety of high-rise buildings in the wake of the Grenfell Tower fire in 2017.

The fund is designed to support building owners and residents in the removal and replacement of unsafe cladding systems, including those made of aluminum composite material (ACM) and other combustible materials. The fund is available to both private and social housing sectors, as well as other types of high-rise buildings such as hotels, student accommodations, and hospitals.

The government has allocated £5 billion to the fund, with £3.5 billion earmarked for the remediation of high-rise residential buildings, and an additional £1 billion for the remediation of non-residential high-rise buildings. Building owners and managers can apply for the fund through an online application process, which includes providing evidence of the unsafe cladding and details of the remediation plans.

The Building Safety Fund is just one of the measures that the UK government has put in place to improve the safety of high-rise buildings in the wake of the Grenfell Tower tragedy. Other measures include changes to building regulations, increased fire safety inspections, and the establishment of a new regulatory body, the Building Safety Regulator, which will oversee the safety of high-rise buildings.

7. WHAT DOES IT COST TO RECLAD A BUILDING?

The cost of recladding a building in the UK can vary depending on several factors, such as the size and complexity of the building, the type of cladding material used, and the extent of any remedial works required. However, as an approximate guide, the cost of recladding a building in the UK can range from £200 to £1,000 per square metre. For example, recladding a small residential building with basic materials may cost around £10,000 to £30,000, while recladding a large commercial building with high-quality materials and complex designs may cost several million pounds.

It's important to note that the cost of recladding a building in the UK has increased in recent years due to concerns about fire safety and the need to comply with stricter building regulations. The cost of upgrading a building's cladding system to meet current fire safety standards can be significant, particularly for buildings with high-risk cladding materials such as ACM, which can require complete removal and replacement.

In addition to the cost of the recladding itself, there may be additional costs associated with the need to comply with building regulations and fire safety standards, which may require additional fire protection measures, such as fire-resistant insulation, or the need to upgrade other parts of the building's structure. It's advisable to seek the advice of a qualified building surveyor or construction specialist like T&T Facades / T&T Cladding Remediation to obtain an accurate estimate of the cost of recladding a building in the UK. They can provide a detailed cost breakdown and identify any potential issues that may affect the cost of the recladding project. T&T provides a free consultation and quotation service.

8. How does fire rating affect my cladding project?

Reaction to fire of all products is an essential consideration for any cladding project, as it determines the level of fire safety protection that the cladding system provides for a building. Fire rating refers to the length of time that a cladding system can resist fire before it fails, allowing fire to spread through the building.

The fire rating of a cladding system is determined by various factors, including the type of cladding material, the thickness of the cladding panels, and the way that the panels are installed. Explicit tests must be strictly adhered to, to provide a reaction to fire class of A2-s1-d0 or A1.

When planning a cladding project, it's essential to ensure that the chosen cladding system meets the requirements of regulation 7 as well as the required fire rating for the building's height and intended use. This is particularly important for high-rise buildings, where fire can spread quickly through the building and cause significant damage and loss of life.

In some cases, it may be necessary to incorporate additional fire protection measures, such as fire-resistant insulation, in order to achieve the required fire rating for the cladding system. It's also important to ensure that the cladding system is installed correctly and that all relevant fire safety regulations and standards are met.

Failing to take into account fire rating requirements can lead to serious consequences, including the potential for fire to spread quickly through the building and cause significant damage and loss of life. It can also result in costly remedial works and legal liabilities if fire safety regulations are not met.

9. CAN I SELL MY PROPERTY WITH CLADDING ISSUES?

If your property has cladding issues, it may be difficult to sell it as many buyers may be hesitant to purchase a property with potential fire safety risks. The cladding issue has become a significant concern for many homeowners in recent years due to the Grenfell Tower tragedy in 2017, which highlighted the importance of building safety.

Depending on the severity of the cladding issues and the type of cladding used, you may need to take steps to remediate the issues before putting the property on the market. This may involve replacing the cladding, conducting a fire risk assessment, or implementing other safety measures to ensure the property is safe for occupants.

It's essential to note that many mortgage lenders and insurers have become cautious about lending on or insuring properties with cladding issues without an appropriate EWS1 form (see below). As a result, if you choose to sell a property with cladding issues, without a EWS1 form, you may have limited options for potential buyers, and the sale price may be affected.

Therefore, it's advisable to consult a qualified building surveyor or fire safety expert to assess the cladding issues and provide recommendations on how to remediate them. This will not only help to ensure the safety of the property's occupants but also increase the likelihood of finding a buyer and achieving a fair sale price.

10. WHAT IS AN EWS1 FORM?

An EWS1 form (External Wall Fire Review) is a standardised document that assesses the external wall construction of high-rise residential buildings (typically over 18 meters tall) and determines whether there are any fire safety risks associated with the building's cladding system.

The form was introduced in the aftermath of the Grenfell Tower tragedy in 2017, which highlighted the importance of fire safety in high-rise buildings. The form is used by lenders and surveyors to assess the fire risk associated with a property's cladding system, (and external wall) and it aims to provide greater transparency and consistency across the industry.

The EWS1 form is usually completed by a qualified fire safety expert or chartered building surveyor, who will inspect the building's external wall construction and determine whether any remedial action is required to mitigate fire risks. The form will detail the results of the inspection, including any remediation works that are necessary and any risks that may be associated with the cladding system.

The EWS1 form is typically required when buying or selling a high-rise residential property, or when applying for a mortgage or insurance on such a property.
