What we’ve done

Hall Pacific has delivered a range of dredging and climate change adaptation solutions in the Pacific Islands.

We have successfully designed and built seawalls and artificial reefs, carried out land reclamation works and undertaken flood mitigation dredging in areas such as Fiji, Tuvalu and Papua New Guinea.

Some of the projects we’ve delivered include:

Nukufetau seawall AND cyclone recovery work

Nukufetau, Tuvalu
Government of Tuvalu and the United Nations Development Program
$9 million
Ongoing

During 2015, Tropical Cyclone Pam battered a seawall off the Nukufetau atoll, causing concrete blocks to dislodge and damage the community settlement.

In response to this issue, Hall Pacific was engaged to design and construct a 500-metre-long replacement seawall including an additional seawall crest to improve resilience to overtopping.

Our team also proposed designs for submerged wave breaks, which are used to dissipate wave energy, effectively reducing the height of a wave before it reaches the seawall. A strong focus was placed on understanding the natural coast process and working with the environment to develop sustainable and effective solutions.

Funafuti Borrow pit remediation

Funafuti, Tuvalu
Government of Tuvalu and New Zealand Ministry of Foreign Affairs (MFAT)
$8.3 million NZD
January –November 2015

In past years, Tuvalu has battled with sanitation and environmental issues caused by ‘borrow’ pits that were dug on the Funafuti atoll during World War II to aid in building an airstrip. Tidal movements resulted in rubbish as well as human and pig waste collecting in the pits and seeping through the porous coral floor and into the lagoon. This was not only unsanitary, but also increased the amount of nutrients and heavy metals entering the lagoon, causing significant damage to coral communities and ecosystem function.

Hall Pacific was engaged in 2015 to dredge more than 365,000m3 of sand from a local lagoon to fill the pits. In doing so, our team increased the useable land space in the area by eight percent, creating more open space to be used by the community. The works also minimised pollution and improved hygiene levels on the atoll.

As part of this project, our team also constructed a sandbag wall to protect against coastal erosion on Funafuti. This effectively repaired a breach in the coral atoll, removing the threat of the atoll splitting in two.

Nadi River flood mitigation dredging

Nadi, Viti Levu, Fiji
Fiji Government
$8 million (FJD)
2008-2010

With many of Fiji’s coastal rivers suffering from serious sediment build-up as a result of soil erosion in the upper catchments, and tropical rains and cyclones posing significant flood threats to towns and villages in coastal deltas, Hall Pacific was engaged to remove excess sediment from the Nadi River in 2008.

Following the successful completion of this contract, our team has since been awarded a further three contracts on-site, dredging a total of 1.6 million m3 of sediment and significantly reducing the impacts of flooding in the area.

Local Fijian operators and crew formed an integral part of the project, with Hall Pacific also training government surveyors in hydrographic survey techniques..

Nabouwalu Jetty replacement & repairs

Bua, Vanua Levu, Fiji
Fiji Roads Authority
$4.2 million (FJD)
October-December 2015

Servicing a range of ferries, shipping vessels, police, customs and navy personnel, the Nabouwalu Jetty provides a key transportation link between the Vanua Levu and Viti Levu islands in Fiji. Hall Pacific was contracted to undertake interim repairs to the jetty and causeway in 2015 including:

  • isolating the existing jetty and jetty extension;
  • installing a steel deck over the existing ramp to prevent failure of the underlying concrete structure;
  • consulting with key stakeholders to achieve the best possible outcomes;
  • dredging the seabed to provide sufficient depth for shipping across a full tidal range;
  • installing mooring dolphins to assist with mooring of vessels; and
  • conducting repairs to the existing causeway, including the road surface and rock armour.

The contract was carried out in stages to ensure the jetty remained operational during the construction period.

Funafuti waterfront recreation area reclamation

Funafuti, Tuvalu
Government of Tuvalu and New Zealand Ministry of Foreign Affairs (MFAT)
$3 million (AUD)
December 2015–April 2016

Following on from a number of successfully completed projects in Tuvalu, our team was contracted once again in 2015 to dredge approximately 35,000m3 of sand and limestone from the existing lagoon. This material was pumped to a reclamation area along the coastline, with works including the construction of sand containers on both sides of the 16,000m2 area.

Our team also carried out replenishment works along a narrow strip of the rocky foreshore, creating a valuable beach for the residents of Funafuti.

Ba River flood mitigation dredging

Ba, Viti Levu, Fiji
Fiji Government
$4 million (FJD)
May-November 2015

A major river in Fiji, the Ba River flows through the town of Ba, a significant agriculture and industrial city on the island of Viti Levu. During the wet season, severe flooding regularly causes damage to local infrastructure and the lives of people in the area.

Hall Pacific was engaged in 2015 to assist in managing this issue. Our team dredged 450,000m3 of sediment from the river to reduce the effects of flooding.
