The Tuas mega port is a major milestone in Singapore’s next generation container terminal development with the long-term project, that includes four phases, targeted for completion in the 2040s. In the reclamation of the second phase, also known as the Tuas Terminal Phase 1, approximately 320 hectares of land was reclaimed. A total length of approximately 8.6km of vertical seawall structure was constructed along the perimeter to provide land with terminal berthing facilities. Gravity retaining walls in the form of pre-fabricated caissons were adopted to form the required vertical seawall structures and as the ERSS system to retain reclamation fill within the development area.
The caisson wall structure has a typical size of 28m (width) x 28.15m (height) and 29.9m to 39.9m (length). The caission wall is seated on top of a typically 2m thick rock mound, which sits on a compacted sand key foundation. As the QP (Geo), we designed the above mentioned structural elements which were under the category of geotechnical building works.
