The team working on the underpass are tackling this challenge from all sides, literally.
In the central section, with the shift to being able to work from the motorway median we’ve been continuing with piling for the underpass walls and roof. On the western side, we’re busy building the retaining walls which will form the sides of the underpass while on the eastern side, we’ve already started to excavate some of the material. Known by the team as the ‘big dig’, phase one is currently underway and 2,149m³ of material has already been excavated with another 2,900m³ to go. In total, 16,000m³ of material will be excavated across three phases.
We caught up with Josh and Paul who have been keeping us updated as we can’t go to this area of site for safety reasons.
“Before we could start any excavation, we had to set up a ventilation system. This was really important as we have to ensure that all the dirty air which has a higher concentration of carbon monoxide in it is removed for the safety of the team working in the underpass” says Paul.
