Announcement of the winner of the Geotechnical Analysis competition won by ITS Wani Team with their Raft pole Foundation Design.

ITS Campus, ITS News – Incessant students of Institut Teknologi Sepuluh Nopember (ITS) showed their ability in national level competitions in various fields. This time, the new achievement by a team of students of the Civil Engineering Department who won first place in the Geotechnical Analysis competition at the Civil National Expo 2021 held by Tarumanegara University some time ago.

The geotechnical analysis competition win by the ITS Wani Team. Consist by Wildan Pramadistya Rifliansah, Muhammad Farhan Firmansyah, and Willy Tantowi. In the race that lasted until the end of May. The participants were asked to design a foundation of a raft pole that could withstand the load of the building on it.

Team Leader Wani, Wildan Pramadistya R. explained that the question shared during the race that started on March 12th contains a case study with information in the form of layout, elevation of the building, and soil test results in the form of Standard Penetration Test (SPT). The results of this soil test are one of the benchmarks in designing the foundation. “The given building is a 20-story building with four basement floors. Model of the building is done by our team,” he explained.

Wildan mentioned that the foundation of this raft pole is a combination of shallow foundation and deep foundation. The components of the raft are shallow foundation parts and the pole components are the inner foundation parts.

The design was made using the concept of creep piling design which requires that the pole under the foundation of the raft should be mobilized load about 70-80 percent. “We got a total of 44 poles with a length of 21 meters and a diameter of 0.7 meters,” said Wildan.

He added that their team created a chart that ultimately contributed greatly to the team’s victory. This graph can present variations in the number of poles, diameter, mobility, as well as their descent. Thus, it can be known which variables can provide optimal stability.

“With the combination of graphs and the concept of creep piling in the preliminary design stage, the number of poles and diameters mentioned earlier that can withstand the load of the building of 52,625 tons,” he explained.

Wildan continues, the graph created by the team of students of the class of 2018 received praise from the judges. In the final stage, the jury acts as the owner of the project, while the team of participants acts as contractors during the presentation. According to the judges, the graphics they created were similar to those used in real construction projects. “This graphic is similar to what contractors used when tendering,” he said.

Students from Sidoarjo claimed that the design of the foundation of the raft pole is a new thing for them because the combination of the deep and shallow foundation was never studied during college. With the help of supervising lecturer Dr. Yudhi Lastiasih ST MT, they searched for various related literature and received many revisions and inputs. “The problem of data processing has been studied in college, but the design of the foundation of this raft pole is still very new for us,” he added.

Ending the interview, Farhan said, Team Wani’s victory was certainly carried with enthusiasm and dedication by its members. In addition, good preparation in completing case studies also has a big role in the smooth running of the team. “It was this enterprising team that finally helped us win one of the five teams that made the finals,” he concluded.
