Southland Holdings wins the Tunnelling Project of the Year (over $150m) award from New Civil Engineer Tunneling for its work on the Kaneohe/Kailua Sewer Tunnel Project. 

Judges’ comment – The first tunnel project of its type in Hawaii (on the island of Oahu) including several ground treatment and support methodologies in difficult water bearing ground conditions. The interface and expectations of the immediate community were a major feature for the project team to manage including training and employing local people. Given the sensitivities of caring for the island heritage including noise control the Mayor of the community praised the construction of the project for its minimal impact, and ensuring public health and environmental sustainability for generations to come.
