You say that but when the entire construction work force has the mindset of "the sooner we finish the job, the sooner I'm unemployed" not a whole lot gets done. Combined with people who have no idea what they're doing and contracting more people who don't know what they're doing and you get $600mil+ over budget and not even close to finishing.
In Queensland last year I think the whole thing was $2bil over. We were the 3rd set of contractors to do exactly the same tasks at the same locations. Was a clusterf**k. Pretty much sums up mining/oil/gas construction jobs. And now that they're wrapping up, all these Muppets from WA, SA, NT and QLD will be looking for more stable work. A large percentage of the skilled workers are foreigners too. Goddamn south African migration on some sites.
