Climate Resilience Projects
Bluecoast undertook the scoping, prioritisation, detailed design, procurement and construction of coastal defences along the Hahake (East) coast of Tongatapu, the largest and most populated island of the Kingdom of Tonga as part of the Asian Development Bank (ADB)-funded Climate Resilience Sector Project.
Extensive stakeholder engagement was undertaken with local communities, the government as well as the ADB and local contractors to determine the most appropriate method of coastal protection measures. Numerical modelling was undertaken to quantify design parameters to determine the most suitable method of coastal protection for at-risk sections of the coastline.
A locally sourced rubble mound seawall was designed to protect the most critical section of a coastal road used to access important emergency inner-island evacuation routes. Local contractors were engaged and trained in the sourcing of rock and build of a modern seawall. Bluecoast assisted in the tender selection process, contract administration and site supervision throughout the construction phase.
