+ Structural work

Structural work is at the heart of everything we do and our position as one of the leaders in complex structural construction is well established.

+ Our Structures Division

Our Structures Division has unrivalled experience in both complex basement construction and superstructure work. This gives us the ability to deliver both basement and superstructure works concurrently, whilst many contractors would subcontract this specialist element of work. Knowles’ unique offering allows us to be dynamic, reactive and competitive in this space.

Our experience makes us the perfect partner to also deliver complex superstructure works alongside our basement services, allowing clients to appoint a single contractor for:
• Soft strip
• Demolition
• Façade retention
• Temporary works
• RC frames
• Perimeter secant piling
• Load bearing piling
