Abstract
Apartemen X merupakan salah satu hunian vertikal tingkat tinggi dengan ketinggian mencapai 53 lantai yang dibangun di pusat kota Surabaya yang padat lalu lintas. Oleh karenanya, mengingat lokasi apartemen yang berada di lahan terbatas, diperlukan kebutuhan lahan parkir bagi para pengunjung dan pemilik dengan perencanaan 3 lantai basement, dengan elevasi -12.50 meter di bawah tanah. Dalam perencanaannya, lantai basement membutuhkan konstruksi penahan tanah. Apartemen X dibangun diatas tanah lempung lunak mencapai kedalaman 18 m, dan memiliki kondisi muka air tanah yang cukup tinggi, yaitu pada kedalaman -1 m s/d 2 m. Pada perencanaan eksisting, menggunakan pondasi bored pile yang dipergunakan untuk podium, dan pondasi raft on pile untuk hunian towernya, sedangkan perencanaan eksisting konstruksi penahan tanah, menggunakan jenis secant pile dengan diameter 1,2 m dengan memiliki kedalaman 25 m dan 27 m. Pada tugas akhir ini dilakukan evaluasi terhadap perencanaan pondasi bored pile dan evaluasi konstruksi penahan tanah secant pile dan dengan soldier pile. Konstruksi penahan yang terpilih adalah yang biayanya lebih efisien. Setelah itu dilakukan penjadwalan mobilisasi material untuk alternatf terpilih. Dalam tugas akhir ini dilakukan evaluasi pondasi menggunaan bored pile dengan diameter 1200 mm, serta didapatkan konstruksi penahan tanah yang memiliki biaya lebih efisien menggunakan secant pile dengan diameter 1200 mm. Dari hasil penjadwalan diperoleh durasi pengangkutan material beton adalah 38 hari dan durasi pengangkutan tanah pekerjaan penggalian tanah penahan tanah adalah 62 hari.

Apartment X is one of the high-level vertical dwellings with a height of up to 53 floors which was built in the center of Surabaya, which is heavy traffic area. Due to the limited area, parking space is needed for visitors and owners with the planning of 3 basement floors, with elevation -12.50 meters below ground. The X apartment project was built on soft clay soil reaching a depth of 18 m, and has a high groundwater condition, which is at a depth of -1 m to 2 m. In the existing foundation planning in this building, using the bored pile foundation used for the podium, and the raft on pile foundation for the tower occupancy, while the existing plan for retaining construction in this building, uses a secant pile type with a diameter of 1.2 m with a depth of 25 m and 27 m. In addition, given the location that is in a dense traffic area, it is necessary to pay attention to the process of scheduling the mobilization of materials. In this final project, an evaluation of the foundation planning and evaluation of the retaining construction is followed by calculation of alternative retaining construction planning to get a comparison of the results of the existing planning.
In this final project, an evaluation of the foundation using a bored pile with a diameter of 1200 mm was carried out, and a more cost efficient soil retaining construction was obtained using a secant pile with a diameter of 1200 mm. From the scheduling results, it is obtained that the duration of transporting concrete material is 38 days and the duration of land transportation for the excavation of retaining soil is 62 days.
