MONADELPHOUS CONTRACTS UPDATE

Leading engineering group Monadelphous Group Limited (ASX: MND) ("Monadelphous" or "the company") today announced it has secured water and transmission pipeline construction contracts in Western Australia (WA) with a combined value of approximately $180 million.
The first is for Rio Tinto's Coastal Waters Project at Bungaroo Valley in the Pilbara region of WA. The contract comprises the construction and installation of a potable water supply system that will deliver
10 gigalitres per year of potable water from the Bungaroo Valley to the West Pilbara Supply Scheme at Millstream, WA. The system includes a bore field, approximately 15 kilometres of collector main
and 87 kilometres of transfer pipeline and a transfer pump station.
Work is expected to commence in the first quarter of the 2012 calendar year and is scheduled to be completed in the first half of the 2013 calendar year.
The second contract, awarded by Chevron Australia, is for the preparation and construction of a CO2
injection pipeline and well sites on the Gorgon Project, Barrow Island, WA.
This contract, secured through Monadelphous's transmission pipelines business KT Pty Ltd, comprises installation and pre-commissioning of seven kilometres of underground pipeline, five well sites and associated facilities.
Work will commence immediately and is scheduled to be completed in the first quarter of the 2013 calendar year.
This is the third pipelines contract secured by the company on the Gorgon Project. It follows the installation of pipelines, cables and tubes for Chevron Australia and the construction of the onshore DomGas Pipeline for Clough Sea Trucks Joint Venture.
The Gorgon Project is one of the world's largest natural gas projects and the largest single-resource project in Australia's history. It is operated by Chevron and is a joint venture of the Australian subsidiaries of Chevron (approximately 47%), ExxonMobil (25%), Shell (25%), Osaka Gas (1.25%), Tokyo Gas (1%) and Chubu Electric Power (0.417%).
"These contracts support our objective of sustainable growth through the continued expansion of our infrastructure business and they build on our long term relationships with blue chip customers," Monadelphous Managing Director Rob Velletri said.
The latest contracts take the total value of new work secured by Monadelphous in the 2012 financial year to more than $1.5 billion.
