Rigging outside the square

That looked like a really cool job to be involved with! How long did it take to get all the lines in place?....really good pics too!!

Was there a lot of head-scratching when it was decided the crane couldnt be used, or was this all part of a pre-conceived plan?

 

Andy it was made very clear to the company that was doing the job that the crane was not practical very early on....when I got a call it was my first reaction too, crane has to be the most sensible approach???? Just proved not to be possible the road is such a major artery into Brisbane that I can (kinda) understand the reticence to the idea of blocking it off, a 180 or 200+Ton crane would have reached the job site from the road (before the bridge)

 

How long did the job take to do start to finish?

 

It blew out by a week...they had some very bad weather three days into the cutting and could not get onto the river banks for a couple of days...more trees fell (not onto the pipe!)

 

did you guys have it (the tree stem) braced lower down at all?

 

No the lower portion of the root ball was still attached to the bank proper and well and truely jammed against the pipe. I have no pics of the final stages of the job sadly.

How long did it take to get all the lines in place?....

 

Four days...three days for the four A frames and a day to get all the cables properly tensioned.

Great job, great pics.

i take it any trees close to the pipe will get taken down now after this?

[sean freeman]

Ha ha, yes very likely, though not all that simple since the pipes are very long and cross a few creeks/rivers, many different protection regulations envolved, just like the UK I suspect.

 

The issue for the river banks I suspect is that when they created the cuttings for the road they extensively filled the banks with spillage from the civil works...and now some 30yrs on we are dealing with those consequences combined with the alteration to the flow of the river after all the decades of urban infill.
