Project Kells

CASE STUDY

Basement construction in the heart of Dublin city centre

Project Kells occupies a curved corner close to Trinity College

John Sisk & Son is building Project Kells retail and office development in Dublin city centre. It is bounded on two sides by roads and existing buildings. Tracks and overhead lines for Dublin’s Luas transit system also run alongside the site.

Demolition phase, July 2019

Secant piled retaining wall

The new building will have six floors above ground and two basement levels, with the basement being excavated to a depth of 9.5m across the entire site. This basement has been created by installing a secant piled retaining wall around the perimeter, made up of 360 piles averaging 15m in depth.

The curved corner section of this secant piled wall is tied back under the Luas lines by permanent 15m long ground anchors installed at an angle of 45o.

Digital Project Delivery

Project Kells has presented a number of key challenges with the complexity of the build but Sisk and our supply chain partners were able to overcome them.

The use of innovation in our approach towards our construction methodology using 4D construction planning which allowed us to build the projects virtually using multiple scenarios to ensure we had 'right first time construction'.
