John Sisk & Son is building 60 Dawson Street 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.
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.
60 Dawson Street 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'.

The Sisk team kicked off Safety Week 2020 by hosting guest speaker Drew Flood from the mental health charity, Aware. This visit was to coincide with the theme ‘Mental Health, Welfare and Wellbeing in Construction’.
Drew spoke to staff and supply chain partners about how important it is for men to talk about mental health and any issues they may be facing. He also drew attention to the services offered by Aware and urged anybody in difficulty to reach out.
