Science Centre Station Update
Pedestrian tunnel
• has been fully waterproofed and U-fill has been placed to nearside of the struts allowing struts to be
removed.
• falsework has been removed inside and is stacked ready to be hoisted out allowing backfill to commence.
• Once backfilled, temporary pavement can be reinstated.
Main entrance
• excavation is past 3m deep and all crossing utilities are now supported.
• excavation work has been accelerated to 12 hour workday, plus half days on Saturday, thereby allowing us
to accelerate excavation schedule by approximately 3 weeks
• Accelerating the excavation schedule provides us flexibility to better manage traffic, intersection piling and
deck installation opportunities.
