The site is located on the corner of Dawson and Nassau Street and just a few minutes from the primary shopping district of Grafton Street. This district has one of the highest footfalls in all of Dublin. Project Kells creates numerous new development opportunities. It will include range of retail and office space once complete.
Lafferty, the project managers, oversaw the demolition of three main structures: Nassau House, Hibernian Corner & Hibernian House. The site location has presented many difficult challenges with the LUAS track positioned on two sides of the site. Access also has been very restricted and has required careful execution in this live environment.
Wykamol were asked to look at the plans of this project 2 years ago and to design a Type C waterproofing scheme to protect the internal structure and bring the basement up to to Grade 3 environment.
Careful design consideration was needed for this large two storey basement structure as the depth across the entire site was 9.5 metres below ground.
Drainage was going to be crucial in this scheme and the perimeter channels that were to be used, needed to allow drainage to lower floor areas.
A bund wall system was incorporated into the design to move any potential water away from the structure. And in to a pumped drainage system via our perimeter channel system with jetting and access points.
Type C membranes are being installed to wall and floor areas within this mammoth underground space.
Working on previous waterproofing projects like this has been invaluable. We have been involved with many 5 and 6 storey deep construction projects where similar drainage and waterproofing schemes have been used.
We were able to incorporate the designs and experience from these projects to help us with the design criteria of this project.
We’re proud to be working with Drytech Waterproofing on this site for building contractors, John Sisk. We cannot wait to see the finished project once opened.
