THE USE OF GEOTEXTILE CONTAINER FOR SHORE PROTECTION WORK AT EAST COAST PARK AND PASIR RIS PARK IN SINGAPORE

The sandy beach at East Coast Park is the favourite haunt for sun-loving Singaporeans. Contrary to popular belief, the beach there is not natural but man-made and a fruition of reclamation works during the period between the 60s and 80s. The beach in the East Coast Park and Pasir Ris Park had been designed based on the concept of a series of headland breakwaters scheme and the formation of crescent shaped pocket beaches between headlands. As the beach is constantly been exposed to incoming swell waves, it tends to show signs of erosion at some stretches of the beach along East Coast Park and Pasir Risk Park. Faced with the prospect of receding shorelines from these wave attacks, the Building and Construction Authority (BCA) has been tasked to restore the beach at East Coast Park and Pasir Ris Park. BCA had appointed the Housing and Development Board (HDB) as their technical agent to carry out the beach restoration works and Surbana International Consultants Pte. Ltd. (Surbana) as the project consultant. BCA/HDB will be jointly referred as Client in this paper. Client has supported a pilot proposal of using sand-filled geotextile containers as revetment instead of the conventional rock revetment at designated stretches of shore in East Coast Park (ECP) and Pasir Ris Park (PRP), Singapore. This is the first beach restoration project in Singapore which is carried out along well developed coast in close proximity of urban habitat. The piloted project of using sand-filled geotextile containers has been successfully implemented at 3 locations of East Coast Park and Pasir Ris Park. They are found to perform satisfactory in protecting the shore from the continuous wave actions and blend with the natural surrounding very well.
