The fallback option for a major road and tunnel project in Australia now includes the possible payment of compensation should construction delays hold back its opening. The potential compensation package is being planned by the Victoria State Government to Transurban for Melbourne’s massive US$4.73 billion (A$6.7 billion) West Gate Tunnel project. The size of the compensation fee remains as yet unannounced, although some estimates suggest it could be as high as $1.27 billion (A$1.8 billion). Transurban expects to receive compensation should contract terms for the project not be met. Construction of the West Gate Tunnel faces challenges due to disputes between the construction firm and the unions.
