The New Zealand Contractors Federation has awarded the Hobson’s Bay Sewer Tunnel project the 2009 Environmental Award for Contracts over $10 million.   This achievement recognises the dedication that joint venture partners MacDow and Fletcher have shown to protecting the environment through both design innovation and construction implementation. The use of TBM technology in the delivery of the tunnel allowed a shallow alignment to be selected, reducing pumping requirements and energy demand. This reduction in energy consumption is approximately equivalent to a reduction of 160T of carbon dioxide per annum. On a local level the project was delivered within 100 m of local residents without significant disruption. The provision of a noise proof shed above Read more
