The internship was mainly concentrated on SP PowerAssets’ Jurong Island to Pioneer Transmission Cable Tunnel (JIPCT) project under main contractor, Penta Ocean Construction Co Ltd., and consultant, AECOM. In order to build a 5 kilometer transmission cable tunnel in about 45 meter depth, three permanent shafts are made with diaphragm walling method to ensure a safe entry of TBM and other machineries. I have participated mostly in the diaphragm wall construction as a Site Engineer whose responsibility is to realize and implement the structural design on ground.
A diaphragm wall is a reinforced concrete wall that built to hold nearby soil pressure while a deep excavation is conducted. Each panel construction begin with the construction of guide wall, followed by the excavation process with the support of bentonite slurry. The panel finally will be casted by using tremie pipes after the reinforcement cages and CWS joint are installed. I mostly spend my internship works at JIPCT Shipyard Site, however, I also did minor job such as planning and design for West Jurong Island site’s project.
Overall, the internship is a very useful experience and has given me a lot of new skills and knowledge about civil engineering world generally both related to my academic life as a student or not related, such as management and practical skills that also required to solve any problems which might delay the project. The internship has given me new insights and motivation to do another internship during my studies as well as to pursue my career as a civil engineer at a higher level.
