Project SHEET Newcastle, Australia NCIG Berths 8 and 9 Dredging Project

INTRODUCTION features For 200 years the has been Client Newcastle Coal Infrastructure Group, Australia’s premier coal export harbour. Of the 95 with Aurecon Hatch as EPCM Contractor Mtpa of various commodities such as steel, aluminum, minerals and so forth exported from Location Newcastle, Australia Newcastle in 2008-2009, 90.5 Mtpa were Period November 2007 - May 2010 attributable to coal. Average annual growth rate of coal exports from 1990 to 2006 was 6.1%. Contractor Boskalis Dredeco Joint Venture This constant increase has caused a spike in ships queuing to enter the harbour to be loaded. To increase capacity and avoid these traffic jams, a decision was made to develop a new coal stockpile area and construct a third coal terminal.

In April 2007 the Newcastle Coal Infrastructure Group (NCIG) received approval from the Government to proceed. NCIG has a 35-year lease on the 136-hectare site on Island and construction on Stage One of the facilities with capacity to load 30Mtpa is almost completed. The shiploading facilities have been built to the west of the existing Kooragang A shiploaders, with the new stockyards and rail facilities to the south-west of the Kooragang Coal A Location map Terminal. The port is located at the mouth of the B The cabins of the backhoes are equipped with Hunter River which, as part of the project, was state-of-the-art technology C deepened to allow ships to reach the new berths. The backhoe operation in full swing D Aerial view of the Newcastle project in progress The goal is to maximize the productivity of the Hunter Valley coal chain. PROJECT SPECIFICATIONS The original Boskalis Dredeco Joint Venture contract with NCIG was to dredge in preparation for Coal Export Terminal 3, with a capacity of 30 Mtpa. Material from the South Arm of the Hunter River would be removed to create two berth pockets (Kooragang K8 and K9). During execution of this Main Contract, however, additional works were added:

‚‚ the dredging to the west side of the K9 area to provide sufficient depth along the future K10 Berth Pocket for future wharf B construction (this is part of the NCIG stage 2 works for 45 Mtpa), ‚‚ the precision environmental dredging of clean and contaminated materials
