McDonnell Piling Uses Screwsol\u00ae for Ireland\u2019s Tallest Residential Building<\/h1><\/div><\/div>In Cork, Ireland, McDonnell Piling is working on two major residential projects, including what will be the country\u2019s tallest residential tower. The key innovation: the use of Screwsol\u00ae piles, which generate minimal excavated material and reduce the amount of concrete used! These projects demonstrate Soletanche Bachy\u2019s ability to deploy innovative, high-performance, low-carbon solutions on local projects.<\/strong><\/p>\n<\/div><\/div>Two projects, one technical ambition<\/strong><\/h2><\/div>In Cork\u2019s Docklands, McDonnell Piling is simultaneously contributing to two landmark urban developments:<\/p>\n
\n- Railyard Apartments<\/strong>, featuring a 25-story tower set to become Ireland\u2019s tallest residential building<\/li>\n
- Marina Depot<\/strong>, a large-scale urban transformation program, with a first phase comprising 337 housing units spread across several buildings<\/li>\n<\/ul>\n
Two projects with different characteristics but a common challenge: constructing high-performance foundations in constrained urban environments while minimizing environmental impact.<\/p>\n<\/div>

<\/div><\/div><\/div><\/div>For both projects, the teams opted for a hybrid solution combining CFA piles and Screwsol\u00ae piles, a technology developed by Soletanche Bachy.<\/p>\n
The principle: forming a displacement pile by creating a helical thread filled with concrete, which improves load-bearing capacity while minimizing the removal of excavated material.<\/p>\n
This approach offers several key advantages for urban construction sites:<\/p>\n
\n- Very low (or even zero) volume of excavated material<\/li>\n
- Reduced concrete volumes<\/li>\n
- Fewer truck trips and less construction site congestion<\/li>\n<\/ul>\n<\/div><\/div><\/div><\/div><\/div><\/div>
Concrete and measurable benefits<\/strong><\/p>\nThe results achieved on both projects fully illustrate these benefits:<\/p>\n
\n- Up to a 52% reduction in concrete <\/strong>at Marina Depot compared to a traditional solution<\/li>\n
- At Railyard, 41.9% less concrete and 28% less steel used <\/strong><\/li>\n<\/ul>\n
Beyond the numbers, these gains directly translate into a reduced carbon footprint and improved overall construction site efficiency.<\/p>\n
Expertise That Makes a Difference Right from the Design Phase<\/strong><\/p>\nIn both cases, the early involvement of McDonnell Piling and the Soletanche Bachy teams made it possible to optimize the solutions right from the design phase.<\/p>\n
\n- At Marina Depot, soil analysis led to the decision to use Screwsol\u00ae rather than CFA alone<\/li>\n
- At Railyard, several years of upstream collaboration, including testing, helped secure the final solution<\/li>\n<\/ul>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>
