Don't laugh too hard at the ABC's new satire, Utopia, and the wasteful 
and appearances-driven antics Rob Sitch gets up to as head of the Nation
 Building Authority. It's too close to the truth to be funny.
One of 
the foremost areas where governments need to lift the efficiency of 
their spending - as opposed to cutting payments to the needy or 
short-sighted cost-shifting - is infrastructure. It has become an area 
where too much spending is never enough and anything labelled 
"infrastructure" is above critical scrutiny.
In recent days, 
however, we've been given cause to cast a more sceptical eye over 
spending on capital works. Consider first the views of a highly 
experienced former econocrat, Dr Mike Keating: "Australia has a long 
history of over-investment in infrastructure, with the costs exceeding 
the benefits, and under-charging the beneficiaries so that they demand 
more and more.
"It is therefore most reprehensible that this 
budget prides itself that new spending decisions will add $58 billion to
 total infrastructure investment, when none of the projects announced 
have been ticked off by Infrastructure Australia as having completed 
proper cost-benefit appraisals, probably because a great deal of this 
investment never could pass any proper evaluation.
"And this from a
 government that was properly critical of the former government and its 
approach to the national broadband network. Clearly this improper use of
 the nation's savings is not an acceptable reason for the other budget 
cuts, and the increase in petrol excise should not be tied to an 
increase in uneconomic road funding."
Yes, indeed. It's 
disillusioning behaviour from Tony Abbott, who promised "rigorous, 
published, cost-benefit analysis" of infrastructure projects.
Last
 week, Garry Bowditch, chief executive of the University of Wollongong's
 SMART infrastructure facility, offered a sobering assessment of capital
 works spending, noting that cost overruns have reached between $4 
billion and $5 billion a year.
Value for money is thrown out the 
window, he said, when governments fail to time the construction of 
infrastructure to make sure they're not inflating the prices of labour, 
materials and equipment by competing with the private sector during 
booms.
Adjusted for inflation, Brisbane's Gateway Bridge, built in
 1986, cost about $300 million. But when a second, identical bridge was 
built in 2010, during the mining construction boom, it cost $1.7 
billion.
Bowditch, a former econocrat, called on governments to 
release cost-benefit analyses for Sydney's proposed $11.5 billion 
WestConnex motorway and Melbourne's $8 billion East West Link tunnel.
He
 argued that poor long-term planning by federal and state governments, 
which don't communicate well with each other, had led to unnecessary 
costly construction methods, such as tunnels, because land corridors had
 not been reserved for rail and road development.
Sir John Armitt,
 former chairman of Britain's Olympic Delivery Authority, said we should
 be using technology to improve the capacity of existing rail, road and 
energy networks, and to prepare for driverless cars.
Good point. 
Politicians love cutting ribbons and announcing grand, nation-building 
projects. But they'd waste less taxpayers' money if they got the pricing
 of existing infrastructure right first, and so had a more realistic 
estimate of the demand for additional infrastructure. It's called 
efficiency.
The credibility of economic modelling by allegedly 
independent consultants is surely shrinking before our eyes. Not long 
ago we were treated to the spectacle of two leading firms of economic 
consultants producing diametrically opposed modelling of the cost of the
 renewable energy target. Why? Surely not because they were commissioned
 by outfits with rival axes to grind?
Last week we learnt that 
AMP, whose funds lost a lot of dough after the failure of the outfit 
owning Sydney's Lane Cove Tunnel in 2007, is suing the consultants who 
provided excessive forecasts of the likely traffic flows, accusing them 
of producing figures that were "reverse engineered" by working backward 
from their client's commercial objective. Surely not.
One reason 
it would be good to see cost-benefit analyses of the aforementioned 
infrastructure projects adopted by the Coalition is to test the 
efficiency of Abbott's insistence that he'll finance roads but not 
public transport.
So far the NSW and Victorian governments have 
done a hopeless job of limiting congestion. Since building extra 
motorways adds to demand rather than reducing delays, my guess is 
neglect of public transport is the culprit.
But the Grattan 
Institute's report on cities as engines of prosperity reminds us that 
the longer it takes people to move between home and job, the harder it 
is to fully exploit the "knowledge spillovers" that drive the knowledge 
economy. Didn't you guys say you were worried about slow productivity 
improvement?
