INNOVATION July-August 2012

2011 2012 PROJECT HIGHLIGHTS Cariboo DamFishway Public and private efforts to restore fish and wildlife values in the Brunette River systemhave been ongoing over the past two decades. With the completion of the new Cariboo Dam Fishway in September 2011, fish passage has been increased to a level unseen since the dam’s construction in 1916. The $350,000 fishway required specialized hydrotechnical engineering with the objective of providing fish passage for“all fish, all the time.”Natural rocks and boulders were carefully placed to ensure flow requirements for fish passage were met. The new fishway plays a critical role in the protection and restoration of fish in the entire Burnaby Lake system and highlights the role projects like the Cariboo Dam Fishway can provide in re-engineering a healthy ecosystem.

Repair of Hydrographers Passage Navigational Aid Structures GOAL Engineering provided design for service life extension of five navigational aid structures located in Hydrographers Passage, Queensland, Australia. The work was situated within the Great Barrier Reef Marine Park, a UNESCOWorld Heritage Site. Working closely with the contractor Australian Maritime Systems, work methods were planned that were sensitive to the reef environment and unpredictable weather systems 200 km from shore. Repairs included rehabilitation of structural concrete, installation of galvanic jackets around columns with corrosion monitoring systems, and coating application. Risk mitigation and safety were paramount considering the work vessel was approximately 400 kilometers from its home port. Additionally, Cyclone Yasi passed through the site during the project. Prime Consultant: GOAL Engineering. Lead Engineers: Mark Byram PEng, Greg Ovstaas, PEng. Contractor: Australian Maritime Systems. Owner: Australian Maritime Safety Authority.

Oyu Tolgoi Copper-Gold Plant andMine Infrastructure Located in the remote Gobi desert of Mongolia, Oyu Tolgoi is the world’s largest undeveloped copper-gold project. Fluor is providing program management and EPCM services associated with the 100,000 tpd copper concentrator, open pit and underground mine support facilities, and all infrastructure necessary to produce high-quality copper- gold concentrate. The mine will produce 450,000 t of copper and 330,000 oz of gold per year after starting operations. Construction of the Oyu Tolgoi mine is more than 80% complete at the end of April 2012. Other project infrastructure includes an upgrade to a 104 km road from the Chinese border to the site; a pipeline from a borefield 80 km from the site; and 80 km 2 of site development that includes an airstrip, roads, concrete batch plants, water distribution systems, associated electrical power distribution, and two mining shafts of 1,800 m in depth. Owner: Ivanhoe Mines and Rio Tinto.
