Close interface with wind tunnel reduces concrete high-rise stability system by 20%

Walsh were appointed to deliver the project from planning to completion and build upon the original schemes. With our high-rise expertise and close interface with wind tunnel, we have been able to reduce the concrete in the stability system by approximately 20% and rework the grid to achieve a low-density 200 thick RC slab.

An in-depth value engineering exercise was also undertaken with the Geotechnical consultant to interrogate the design and incorporate a piled raft solution. Doing this resulted in a 25% reduction in the piling requirements for the project, reducing costs and accelerating the programme.

A key feature of the tower is a distinctive step-back of the structure at Level 2, this separates the residential sections from the amenity areas and achieves a beautiful architectural feature that helps the tower stand out. Walsh worked closely with the design team to coordinate the structure to accommodate walking columns that achieved the architectural vision, while keeping the structural solution simple and efficient.

We worked closely with the client to achieve a more sustainable structure. Through close collaboration we managed to specify high cement replacement mixes that reduced the embodied carbon of the structure without impacting on the programme. We also specified high modulus mixed for the stability structure, which, along with a detailed testing regime, allowed for assumptions made within the design to be validated and resulted in a more efficient system that still meets the tight tolerances for tall buildings.

Taking Sustainability Seriously

Sustainability is in our DNA and we have our own ambitious goals to achieve Net Zero as a business and with our designs. With innovative in-house monitoring tools, Walsh clients have seen on average reductions of 10-20% total embodied carbon, with some of our flagship work achieving 60-70% reductions compared with baseline figures.
