TUVALU, PACIFIC ISLANDS
Dredging sand to fill borrow pits and other site improvement works
The Government of Tuvalu and the New Zealand Ministry of Foreign Affairs and Trade engaged Hall Contracting to fill man-made borrow pits and undertake a range of miscellaneous site improvement works on the island.
The borrow pits were created during World War II by the United States Marine Corps, who originally used the material to build an airstrip on Tuvalu. The pits were tidal and leeched waste through the porous coral floor and into the lagoon, affecting the ecosystem and health of the local people.
The project involved dredging more than 365,000m³ of sand from the lagoon to fill the pits.
