28 May - 14 June 2004 - Excavation in Bay 2 & 4
Bedrock is reached in the excavation at a depth of 4.5 metres.
The material being excavated to the rear of the wall is contaminated from the old Richmond Gasworks, which was located on this site. Therefore all excavated material must be removed from the site and sent to a licensed tip.
Stainless steel dowel bars are then grouted into the stone and rock. These bars will tie the stone wall to the new concrete wall.
Concrete is poured into Bay 2 in stages between 2nd and 4th June.
This is done over period of time to minimise the loading on the stone retaining wall.
