Experiencing Press-in Technology for the First Time
Nur Liyana bte Mohd Nor
Final Year Undergraduate Student, Faculty of Civil and Environmental Engineering
Universiti Tun Hussein Onn Malaysia (UTHM), Malaysia

I’m Nur Liyana bte Mohd Nor, a final year student at Universiti Tun Hussein Onn Malaysia (UTHM). I was first introduced
to Press-in technology by my final year project supervisor, Dr. Nor Azizi Yusoff who are actively promoting Press-intechnology at our university and Malaysia. I decided to engage and learn this technology. I was assigned to make a casestudy related to Mass Rapid Transit (MRT) construction that use silent piling technology in Malaysia. For that reason, I
was attached to Koye (M) Sdn. Bhd. who are the contractor for the previous MRT project and supervised by Dato’ Sri
Chung Kian Wai and Mr. Alvin Low.

At the early stage of the industrial attachment, I was introduced with an introduction to the construction of MRT Line 1(SBK Line) and Line 2 (SSP Line), followed with the construction of the MRT Bukit Bintang and SSP Line MRT. Next, I wasintroduced with a more technical document including the soil profile of both MRT project, geotechnical site investigation,
the construction site layout related to the sheet pile construction and the machine used for the installation. Later, I had
been given a chance to experience real life project in Malaysia. For the start, the city drainage upgrading project in Kajang,
Selangor is among the first site for me to experience. For this project, the sheet pile was needed to make a cofferdam asa temporary barrier for the project.

After the site visit at Kajang, I visited the yard, which is where the machineries were kept. The location of the yard was at
Sungai Buloh, Selangor. During the visit at the yard, the Standard Press-in machine and Super Crush Piler can be seen inreal life. For me, it is my very first time to see this. I was excited that the operator had given me a chance to experience
operating these innovative machines. Now, I realize that these machines were equipped with high-end technology. All
movements could be controlled by using a remote radio controller. At the same time, the machine operator also
demonstrated the pile installation by using a conventional vibratory method. Based on Press-in technology andvibrohammer method, it is easy to recognize how Press-in technology could be able to provide such a low noise andvibration on the construction site.
Generally, the Press-in method does not use much human energy as the machine itself has remote to control themovement to drive the sheet pile into the ground. Once the initial piling has been set up which need to operate reaction
stand to support the machine, the remote to control the operation of the pile can be used. The radio controller isapplicable for all operation in Standard Mode, Water Jetting Mode as well as Super Crush Mode. I enjoy to learn this greattechnology. I imagine, the construction work will be more efficient and safe by using this machine. I hope I could learn
more this technology in the near future.
