Contract Value: £1.8 million
Project Duration: 9 months

Description of Services: This project involved External Wall Insulation (EWI) works using a specialist A2 fire-rated system across three high-rise towers. The works were designed and executed in strict compliance with the Building Safety Act and included detailed quality assurance (QA) measures to meet enhanced safety and performance standards. The scope of works also included providing warranties in line with regulatory and client requirements, ensuring long-term safety and compliance.
Project Scale: The project’s significant contract value and complexity—working on three occupied high-rise towers—highlight our expertise in managing large-scale, safety-critical schemes. The specialized nature of the fire-rated system and adherence to stringent building safety standards reflect our ability to deliver projects of this scale and importance.
Resources Used: The scheme was delivered by our in-house EWI installation team with extensive experience in high-rise work, supported by our specialized management and design team. Our team ensured compliance with the Building Safety Act through rigorous planning, execution, and QA processes. Advanced project management tools were employed to track progress, coordinate trades, and ensure adherence to budget and timelines.


Performance Measures: Success was measured through:
- Adherence to the Building Safety Act and achieving full compliance with QA processes.
- Delivery of the project within budget and agreed timeframes.
- Resident and client satisfaction through minimization of disruption in occupied buildings.
- Provision of comprehensive warranties, demonstrating the durability and compliance of the A2 fire-rated system.
Challenges and Solutions: The primary challenge involved working within the constraints of the new Building Safety Act, which required meticulous QA documentation and adherence to enhanced safety standards. Additionally, executing EWI works on occupied high-rise towers posed logistical and safety challenges. We overcame these by:
- Implementing robust QA tracking systems to document and verify compliance at each stage of the project.
- Conducting phased scheduling to minimize disruption to residents while maintaining consistent progress.
- Employing specialized access solutions, such as suspended platforms, to ensure safe and efficient execution of works at height.
Outcome and Impact: The project successfully delivered fully compliant EWI works across three high-rise towers, enhancing the fire safety and thermal efficiency of the buildings. The use of the A2 fire-rated system provided assurance to stakeholders and met the latest safety regulations. Comprehensive warranties ensured long-term reliability and compliance, while the project’s timely delivery demonstrated our capability to handle safety-critical high-rise refurbishments.
