EIA for the proposed Hulhule-Male’ Bridge Project<br />

Landing in Male’ will be via the barge landing area next to Viligilli ferry terminal.<br />

2.4.5 Construction method of breakwater<br />

Breakwater will be constructed using excavators and loaders. The use of cranes may be less<br />

practical given the frequent disruptions anticipated during flight take-off and landing. The core<br />

of the breakwater will be constricted from geobags filled with sand. The upper layers will be<br />

filled with filter cloth and layers of rubble for cushioning. The main breakwater units will be<br />

quadrangle hollow blocks constructed from concrete. These units will be manufactured on the<br />

Hulhule worksite or the pre-casting yard at Hulhumale’ and transported to the site on a need<br />

basis.<br />
