Shares in Decmil were firmer after the resources contractor posted a first-half profit of $44.1 million.
The result was bolstered by a $20.8 million gain arising from the business combination of HomeGround Gladstone accommodation village.
Without the one-off windfall, the company's profit was $23.3 million, up 79 per cent on the previous corresponding period.
The result was achieved on revenue of $332.9 million, up 58 per cent.
Decmil declared an interim dividend of four cents a share, up from 2.5 cents previously.
Chief executive Scott Criddle said while there had been a slowdown in some sectors the company serviced over the past few months, a strategy of building a diversified service offering provided the basis for continued strong results.
"We are aiming to do this through a combination of organic growth and strategic business acquisitions, with a focus on specialist, high-margin targets that will deliver a strong return on investment," he said.
"We are focused on maintaining high cash flow production which will allow our diversification strategy to be executed from the company's internal capital resources.
"While our core business is unchanged, we are certainly examining a number of opportunities within the maintenance and infrastructure sectors which will deliver recurring revenue streams to supplement the project work that has been our staple revenue source since the company was established."
However the company said it expected a softer second half because of project timing.
Decmil held $96.3 million in cash at the end of the period.Shares in the company were up nine cents, or 3.75 per cent, to $2.49 at 8.20am.
