The British Construction & Infrastructure Awards announced their 2026 winners on 14 October at the JW Marriott Grosvenor House Hotel in London. South Wales Metro - Building the Core Valley Lines won the Sir John Armitt Prize, with Transport For Wales as client and Amey Infrastructure Wales as lead contractor and lead engineer.

Organised by the Institution of Civil Engineers and New Civil Engineer, the programme recognises project delivery and positive outcomes for society. This year's results offer something especially useful for future entrants: published judges' comments explaining what distinguished the winning work.

The Sir John Armitt Prize

The judges praised South Wales Metro's widespread community benefits, systems-led approach and collaborative culture, supported by strong client leadership. Infrastructure, rolling stock and operation were brought together rather than treated as separate pieces.

The lesson for your next entry is practical: don't stop at what you built. Explain who benefits, how the partners worked together and what changed for the people using the infrastructure.

Selected Project Winners

These are selected results, not the complete winners list. Official category names are retained below.

  • Commercial Property Project Award: Angel Square, with Tishman Speyer as client, Allford Hall Monaghan Morris as lead architect, McLaren as lead contractor and AKT II as lead engineer.
  • Cultural & Leisure Project Award and Retrofit & Reuse Project Award: Oldham Old Library, with Oldham Council as client, Ellis Williams Architects as lead architect, Tilbury Douglas as lead contractor and Curtins as lead engineer.
  • Environmental Project Award and Placemaking Project Award: Salisbury River Park, with the Environment Agency as client, AtkinsRealis as lead architect and lead engineer, and Kier Natural Resources, Nuclear & Networks as lead contractor.
  • Transport Project Award: Electrification of the Core Valley Lines, with Transport for Wales as client and Amey Infrastructure Wales as lead architect, lead contractor and lead engineer.
  • Water Project Award: Dearne Reach Integrated Constructed Wetland, with Yorkshire Water as client and Mott MacDonald Bentley as lead architect, lead contractor and lead engineer.

The official results page names the other project partners, highly commended entries and finalists. Credit the full team when sharing a result; a project award is rarely the work of one organisation.

Three Things to Learn From the Judges

Make Impact Specific

For Dearne Reach Integrated Constructed Wetland, the judges cited a 60% reduction in embodied carbon alongside improved water quality, climate resilience, biodiversity and community benefits. That figure is reported in the judges' comments; it is not an independent measurement by AwardsApp.

For your own entry, pair a clear metric with the human or environmental outcome it represents. State the baseline, the period measured and where the evidence comes from. A claim of innovation is stronger when you can show its impact.

Show What Collaboration Achieved

The comments on Angel Square highlight stakeholder engagement and integration with the local community. For Oldham Old Library, judges praised the return of a heritage building to civic, educational and community use, and noted that 75% of the supply chain came from the local area.

Don't simply list your partners. Explain the decisions they helped make and the difference those decisions produced. Bring together data and the experiences of clients, users and the project team.

Match the Story to the Category

Salisbury River Park won for both environmental work and placemaking. In the environmental comments, the judges emphasised climate resilience and inclusivity; in placemaking, they highlighted outcomes beyond the original flood-mitigation objectives and how the presentation addressed the criteria.

Run in the right race. The same project can support different entries, but each one needs evidence that answers its own category's questions. Our guide to crafting winning awards entries explains how to turn that evidence into a clear narrative.

If Your Team Won

Celebrate the people behind the result, credit your client and delivery partners, and use the exact category and project name in your communications. Link to the official result so readers can verify it. For a practical follow-through, see leveraging awards for publicity and PR.

If you didn't win, use the published comments as a learning resource, not a template to copy. Identify which outcomes you can already prove and which evidence you need to start collecting for your next entry.
