Infrastructure and engineering company Downer EDI has reaffirmed guidance of double-digit profit growth for the current financial year.

Chief executive Geoff Knox told the company's investor day conference today demand remained strong for Downer EDI's services.

"We see good demand for our services," Mr Knox said.

"It's not happy times, but it's certainly not tragic times. We see good solid demand continuing.

"No material change was made to the company's full year guidance of profit growth at the lower end of a ten to 15 per cent band.

"We're actually travelling reasonably well given the circumstances of the market," Mr Knox said.

Downer EDI posted net profit for 2007/08 of $165.8 million.

The company services the transport, energy, communications and resources sectors across Australia, New Zealand, Asia Pacific and United Kingdom.

Work in hand at March 31 was steady at $13.5 billion, Mr Knox said.

Commodity prices and volumes were "okay" despite falls from their peak in the last financial year, he said.

Discretionary infrastructure spending had fallen, but the main driver of Downer EDI's business, non-discretionary infrastructure spending, remained strong, Mr Knox said.

"It's not easy out there but volumes are holding, and that's great for us," he said.

Downer EDI shares were up 12 cents, or 2.55 per cent, at $4.82 at 10.50am.
