The Pulau Muara Besar bridge was a major construction project to link the Brunei mainland with Pulau Muara Besar, a developing industrial island in Brunei Bay. For large-scale development projects in Brunei and around the world, environmental impact assessments (EIAs) are mandatory to evaluate the project’s potential impact on the surroundings. At the end of the project’s lifecycle, contractors are often required to restore sites to their original states as far as possible.
To execute the bridge construction project, China Harbour Engineering Company Ltd (CHEC) had to clear a nearby site – mainly characterised by mangroves – to be used as a temporary construction yard. After the project was completed, it was time to restore the mangroves.
But it’s not just about planting random species onsite and hoping that they thrive. Many mangrove restoration projects fail because of a lack of understanding of the site hydrology, poor site and species selection as well as the absence of long-term monitoring and management. Recognising that mangrove restoration endeavours tend to have low success rates, CHEC decided to work with an experienced team that could help the mangroves increase their chances of survival.
