Urban construction project

Integrated excellence for complex urban construction

UrbanCore provides best-in-class capabilities in advanced foundation engineering, diaphragm walls, natural stone, reinforced concrete, and steel framing. Our integrated offering combines the strengths of both parent companies, providing unrivalled confidence in deep excavations and anchored retaining walls, and advanced techniques for complex schemes, while ensuring excellence and efficiency.

Our approach offers our clients at the project the benefits of a single contract with our partnership and outstanding track record providing unrivalled UK expertise combined with project-specific international expertise.

One North Quay construction site
Case study

One North Quay

One North Quay is a highly complex project that has seen Kilnbridge and Bachy work together to remove an existing marine deck, install new piles and construct a 130 mtr tall concrete core. This project is a perfect example of this collaboration delivering results in practice, not just in concept.

Why clients choose us

Clients choose us as we bring the best-in-class specialists in ground engineering and structures together in partnership, rather than a subcontract arrangement, to provide unrivalled capability and expertise.

The result is faster programmes & greater confidence in delivery. We build with purpose and responsibility. From reusing and upcycling materials to minimising embodied carbon through precise control of concrete mix design, sustainability is built into the way we work, not added on at the end.
