Closing the Loop: Material Passports in Practice

1 Broadgate is one of London's most ambitious and largest circular fit-outs to date. JLL's 90,000 sq ft office fit-out, delivered by Overbury, is setting a new benchmark for how material data, carbon accountability and circular procurement can be embedded into a major corporate project from day one.

Together, JLL, Overbury and Circuland are delivering one of the most comprehensive Material Passport implementations for a fit-out project to date - covering 20 subcontractor packages and approximately 300 products, with full BIM integration and continuity into FM and O&M systems. The project is currently under construction, with completion expected summer 2026.

• Circular Design & Carbon Reduction: Embedding circular design principles empowers reuse, improves material recovery and supports carbon reduction - contributing to JLL's goal of reducing embodied carbon by 50% by 2030.
• Long-Term Value Creation: Beyond compliance and sustainability, Material Passports create long-term value by extending the lifecycle of materials, reducing future CAPEX and enabling smarter recovery and reuse at end-of-life.
• Data-Driven Decision Making: Capturing carbon, cost and expected lifespan data creates a structured evidence base for better decisions across procurement, asset management and future refurbishments - while maintaining the Golden Thread of data integrity.

The project covers the full scope of the fit-out, including:

Drywall Partitions, Suspended Ceilings, Glazed Partitions & AMRs, CLT Staircase, Folding Walls, MEP & Lighting, Structured Cabling, Security & Fire, Fire Curtain, Fabric Ceiling, Fabric Wall Panelling, Soft Floor Finishes, Landscape & Planting, Catering & Hygienic Walls, Joinery, Blinds & Curtains and Furniture.

For every product and building element, carbon footprint, cost, circularity performance, technical specifications, compliance documentation and geometry are captured and linked directly to the BIM model.

A key feature of the project is the documentation of products across their full origin spectrum - new products, remanufactured components and reused materials are all captured within the same platform, enabling accurate carbon accounting and supporting urban mining and circular procurement strategies.

Delivering Material Passports at this scale requires careful planning, clear requirements and close collaboration with the supply chain. The process followed on 1 Broadgate provides a replicable model for future projects:

• Scope Definition: Identifying which packages and products require Material Passports, establishing the full scope across 20 subcontractor packages.
• Employer Requirements: Developing a clear contractual framework defining what information is required, in what format, by whom and by when.
• Training & Support: Delivering package-specific workshops and training sessions for all 20 subcontractors, ensuring the supply chain fully understands the process and what is expected of them.
• Information Collection: Gathering product datasheets, additional product data and BIM information (IFC models and model schedules) across all packages, with ongoing workshops to ensure alignment between products and BIM elements.
• Quality Review: Circuland reviews both product and BIM data throughout the process, ensuring validity, consistency and completeness before Building Passport creation.
• Creation of the Building Passport: Product data is imported to create individual Product Passports, and BIM data and models are integrated to generate the full Building Passport for 1 Broadgate.

One of the most valuable insights from 1 Broadgate is that Material Passports do not demand information beyond what the industry already captures - carbon assessments, BREEAM and WELL certifications, O&M manuals, Building Control submissions all contain the building blocks. What changes is how that information is structured, shared and used. By capturing it in a standardised, consistent way, duplication is eliminated, data becomes instantly accessible and the intelligence locked inside scattered documents is finally put to work.

The 1 Broadgate project has shown that with the right planning, management and supply chain engagement, Material Passports can be delivered efficiently and at significant scale. And because the same suppliers and products tend to appear across multiple projects, the process becomes increasingly repeatable - moving Material Passports from an ambitious aspiration to a natural part of how projects are delivered.
