Project Summary
In 1999, the Malaysian Government through DID engaged SYS to build a breakwater at the rivermouth of Marang River for the fishermen community and island-hopping tourism. The breakwater, designed in symmetrical bow-shape, had an entrance navigation channel in the middle and two “internal jetties” which forms a constriction to create a flushing effect (with the tides) so that the river channel would not be silted up.
Project Details
breakwater construction
- Made of 255,500m³ of granite rocks.
- Laid on 81,150m² of 390g/m² non-woven geotextile
- Armoured with 37,160m³ of G40 precast concrete tetrapods (56% x7.5MT, 35% x3.8MT, and 9% x11MT) in two layers
- Each arm of the breakwater is approximately 700m long
dredging and land reclamation
- 552,700m³ of sand dredged using a cutter-suction dredger for forming a navigation channel and sedimentation basin
- Sand pumped to nourish the beach at the roots of the breakwater and reclaim land within the breakwater
- 17,800m³ of rocks dredged in the navigation channel using a grab dredger
project challenges
- Initial 8-month delay due to objections from an adjacent beach resort
- Breakwater relocated and realigned to address objections
