Australia-based civil engineering and construction company Decmil Group Limited (DGL) has grossed net profits of $23.3m for the first half of the financial year 2013.

The profits represent a 79% growth over the 2012 fiscal, wherein profits totaled $13m.

DGL attributed the growth in profits to its diverse revenue sources alongside strengthening collaborations with potential resource companies.

Revenues for the company grew 58% to $332.9m for the six-month period ended 31 December 2012 when compared to $210.9m in first half of fiscal 2012.

"The result marks the fifth consecutive year of growth for the business in both revenue and profit," the company stated.

Commenting on the results DGL chief executive officer Scott Criddle remarked that its key arm Decmil Australia contributed significantly to the growth – citing the two $30m contracts it secured with Rio Tinto projects over the period.

DGL has also stated that it submitted tenders worth $1.2bn, results of which are expected to be out in next few months.
