Barossa Valley builder Ahrens wins $40m building contract in WA BAROSSA Valley-based builder Ahrens has won a contract to build a $40 million bulk grain export facility in WA. Global agribusiness and food company Bunge has engaged Ahrens to deliver the design and construct project, which will offer a storage capacity of 50,000 tonnes. Exports from the Bunbury port facility are expected to reach up to 500,000 tonnes in the first two years. Ahrens managing director Stefan Ahrens said the facility would provide WA grain growers with improved access to bulk export markets. "We are very excited to have started work on the bulk grain export facility in Bunbury and to have the opportunity to work for Bunge - a huge company in the international arena," he said. Ahrens will build six 7300-tonne flat-bottom silos and four 700-tonne hopper-bottom silos at Bunbury, as well as offices and other infrastructure for the facility.
