The National Capital Authority has made it known that their long delayed plan to fix corroded bolts on Scrivener Dam (what keeps Lake Burley Griffin where it’s supposed to be) are finally coming together:
The National Capital Authority (NCA) will begin installing replacement anchor bolts at Scrivener Dam at the beginning of March.
The replacement anchor bolts will ensure that the dam’s five flap gates will remain secured to the concrete dam wall. The flap gates are typically lowered during flood events to regulate the water level of Lake Burley Griffin.
NCA chief executive, Gary Rake said the works were identified during an annual safety audit and surveillance inspection of the dam in late 2011.
‘The NCA became aware of corrosion issues related to the original anchor bolts in late 2011.
During 2012 we conducted further engineering investigations, developed and documented a design, obtained the necessary statutory approvals and appointed a head contractor to undertake the works,’ Mr Rake said.
‘Replacing the 120 existing anchor bolts with 60 new bolts has required careful consideration to ensure the work is completed efficiently and with minimal impact on dam operations.
‘The anchor system has been substantially redesigned to meet current design standards.’
By 2014 they expect to get the Lake back to its proper height.

Well thank god it’s only 60 bolts and you didn’t have to build a new dam wall 🙂

Oh you were serious?
Did you miss these bits:
“During 2012 we conducted further engineering investigations, developed and documented a design, obtained the necessary statutory approvals and appointed a head contractor to undertake the works, Mr Rake said.”
“Replacing the 120 existing anchor bolts with 60 new bolts has required careful consideration to ensure the work is completed efficiently and with minimal impact on dam operations.”
“The anchor system has been substantially redesigned to meet current design standards. “
But hey, I’m sure they should have just replaced the bolts quickly without any design or investigations.
It’s not like there’s anything important just downstream of the dam that could possibly be affected by it’s failure……..

Yeah they could have just given Chop a spanner and some bolts. Easy done.
It’s not like the job is possibly complex or involves anything important.
They should use this opportunity to empty the entire lake, clean out all the carp, algae, shopping trolleys, missing persons etc
Inspection late 2011 – Work start March 2013.
Changing 120 bolts for 60 bolts.
…. at this rate imaging how long it will take to build light rail.

yeah I had heard that rumour (probably on this site), but for want of a better term there has been f*** all progress since that announcement
while the lake is at a nice low level is there any chance the local council will get around to fixing the bike path between the hospice and RMC?
The belco red bridge is meant to be going in there, one day.
