Two J’s Metalwork – Leading the Way with BS EN 1090 EXC3, ISO 9001, and Advanced BIM Modelling.
What is BS EN 1090 EXC3?
BS EN 1090 is a European standard governing the fabrication and assembly of steel and aluminium structures. Ensuring compliance with strict safety and quality requirements. The Execution Class 3 (EXC3) certification is one of the highest and most rigorous levels, reserved for structures with significant safety and performance demands, such as:
- Public buildings like stadiums, bridges, or high-rise structures
- Projects exposed to dynamic loads or harsh environmental conditions
- Complex fabrications requiring advanced technical expertise.
Our EXC3 certification reflects our commitment to excellence through:
- Rigorous Quality Controls: From material selection to welding and assembly, every process meets precise technical standards.
- Certified Welding Procedures: Our welders and methods are qualified for EXC3’s demanding requirements, ensuring structural integrity.
- Full Traceability: Comprehensive documentation of materials, processes, and inspections guarantees compliance with CE marking.
- Factory Production Control (FPC): Our production systems are audited to deliver consistent, high-quality results.
Achieving EXC3 places Two J’s Metalwork among an elite group of fabricators, as few competitors hold this advanced level of accreditation. While many operate at lower execution classes (EXC1 or EXC2) suitable for simpler projects. Our EXC3 capability allows us to tackle high-stakes, complex structures with confidence, ensuring safety, durability, and regulatory compliance.
ISO 9001: World-Class Quality Management
The ISO 9001 certification underscores our robust quality management system. Ensuring consistency, efficiency, and customer satisfaction across all operations. This standard drives:
- Streamlined processes for reliable, on-time project delivery.
- Continuous improvement to maintain industry-leading standards.
- A customer-focused approach, tailored to your unique needs.
Advanced BIM Modelling for Precision and Collaboration.
At Two J’s Metalwork, we leverage Building Information Modelling (BIM) to elevate our projects to the next level. BIM is a digital process that creates detailed, data-rich 3D models of structures. Providing seamless collaboration, enhanced accuracy, and optimised project outcomes. Our use of BIM sets us apart by:
- Enhanced Design Accuracy: Our BIM models integrate precise specifications for steel and aluminium components, ensuring flawless alignment with EXC3 requirements.
- Improved Collaboration: We share BIM models with architects, engineers, and contractors, fostering real-time coordination and reducing errors or conflicts during construction.
- Efficient Fabrication: BIM enables us to pre-plan fabrication processes, minimising waste, optimising material use, and accelerating production timelines.
- Lifecycle Management: Our models provide valuable data for maintenance and future modifications, adding long-term value to your project.
By combining BIM with our EXC3 and ISO 9001 certifications, we deliver projects that are not only compliant and high-quality but also technologically advanced. Providing precision and efficiency from design to installation.
