Cracking at the Cotter Dam

By johnboy - 4 June 2012 28

Some very interesting documents have been pushed into the light of day by the FOI process.

It begins discussing the damage caused by the flooding at the Cotter Dam but then takes an interesting turn when cracking is discovered, put down to the delayed concrete pour.

They were hoping it wouldn’t crack and now they hope they can ameliorate the damage, and that it won’t get worse.

Any of our readers with engineering backgrounds care to give their assessment?

‘Après moi, le Deluge’

In so many ways, this should be the motto for this lot.

And dumped under the cover of the ACT Budget! It really is a metaphor for the whole Governmet. Is this another F-up we’ll all be paying for?

Cracks in the wall had to FOIed?

Well, that just about sums up how this government works these days it would seem.

Let me reiterate, cracks in the dam wall had to be FOIed.

Raising eyebrows?

Since when has the lack of an engineering background held some RA readers back from giving engineering assessments? 🙂

It was more a specific invitation.

Having said that, these are not the type of cracks I believe that are inherent to RCC dams, rather, they’ve formed from some issues revealed by the flooding with the abutment structures and from a loss of thermal control of the concrete.

Que?

Does anyone have an emergency response plan for in the case that it gets worse?

If not then…

Before people panic, it’s important to realise RCC dams from the outset tend to be leaky with cracks until they’re sealed after construction anyway.
