Premier Anna Bligh lavished praise on the company.

"Growing from less than 150 staff in 2002 to more than 750 and rising, Sedgman Limited is a Queensland export success story,” she said on Thursday night.

Sedgman managing director Mark Read credited the work of the company’s staff around the globe.

“This award is another milestone in Sedgman’s proud 30-year history and is due to the efforts of all Sedgman employees to create opportunities in the global mining sector that benefit our clients, shareholders and the wider Queensland community,” he said.

"Sedgman is currently focused on a $6.3 billion global pipeline of targeted project opportunities in both coal and metals. More than 25 per cent of targeted opportunities are international, and this is expected to increase as our international offices mature."

Sedgman was also a top-three finalist for the Minerals and Energy award.
