Gedung Center for Advanced Sciences (CAS) adalah salah satu proyek pengembangan infrastruktur untuk menunjang cita-cita Institut Teknologi Bandung (ITB) sebagai World Class Research University. Di dalam gedung ini dibangun fasilitas laboratorium sains tingkat lanjut (Laboratorium Akustik dan Laboratorium Nano Teknologi) untuk Program Studi Matematika dan Program Studi Astronomi. Dalam pelaksanaan proyek, dibutuhkan rancangan pelaksanaan pekerjaan yang baik agar kontruksi dapat berjalan secara efektif, efisien, aman, dan lancar. Rancangan pelaksanaan pekerjaan meliputi site management plan dan site preparation. Site management plan terbagi menjadi 2 sektor, yakni sektor pertama meliputi pembangunan fasilitas kantor dan sektor kedua meliputi lokasi gedung beserta fasilitas pendukungnya. Sementara site preparation meliputi pekerjaan mobilisasi dan demobilisasi, site clearing (pembersihan lokasi proyek), dan pembangunan fasilitas pendukung. Dalam pengerjaan proyek ini, pekerjaan tanah diawali dengan pengukuran untuk menentukan metode kerja pelaksanaan pekerjaan cutting and filling. Dalam hal ini, pelaksanaan pekerjaan cutting and filling terbagi menjadi 2 zona, yaitu zona A dan zona B (basement). Pekerjaan galian dilaksanakan melalui 2 tahap, yaitu




tahap pertama untuk mempersiapkan pekerjaan bore pile dan slab, dan tahap kedua untuk mempersiapkan pekerjaan pile cap dan tie beam. Selanjutnya material tanah hasil galian yang tidak terpakai dibuang ke spoil bank, sementara material timbunan disalurkan ke stock pile. Selanjutnya, pekerjaan back filling dengan compaction dirancang menjadi 4 sektor. Pemadatan dilakukan perlayer




dengan ketebalan maksimal 30 cm dengan alat pemadat (stamper). Pekerjaan pondasi gedung CAS didesain menggunakan pondasi tiang bore pile, dengan pile cap sebagai penghubung antara kolom dan tiang bore pile. Pelaksanaan pekerjaan ini terbagi menjadi 4 sektor. Pekerjaan bore pile dikerjakan dengan metode dry boring system dengan pemasangan cassing. Pengukuran menjadi bagian yang sangat penting pada pekerjaan pile cap, untuk mencegah adanya eksentrisitas pada pendistribusian beban ke bore pile. Pekerjaan ini dilakukan setelah umur beton bore pile mencapai 7 hari

Deskripsi Alternatif :

Center for Advanced Sciences (CAS) is one of the infrastructure’s developments which aimed to realize the vision of Bandung Institute of Technology (ITB) as a




World Class Research University. This building would provide advanced science laboratory facilities (consisting of Acoustics Laboratory and Nanotechnology Laboratory) for Mathematics Program and Astronomy Program. In excecuting this project, a good preparation of project’s construction was really needed, so that the construction can be carried out effectively, efficiently, safely, and succesfully. The work design of this project consisted of site management plan and site preparation. Site management plan was divided into two sectors, namely first sector which includes the construction of office facilities and second sector which includes the location of building and all the supporting facilities. Meanwhile, the site preparation includes work mobilization and demobilization, site clearing (cleaning process arround the project site), and also the construction of all supporting facilities. In conducting this project, earthwork will be begun with site measurement to determine the method of cutting and filling that will be done. In this case, the cutting and filling is divided into two zones, namely A zone and B zone (basement). The excavation is carried out through two stages, namely 1st stage aimed to prepare the bore pile and slab work, and the 2nd stage aimed to prepare




the pile cap and tie beam. Afterwards, the unused soil material that is gotten form excavation process is dumped into spoil bank, and the stockpile material is




drained into stock piles. Furthermore, back filling with compaction will be designed into 4 sectors. Compaction is done perlayer with a maximum thickness of 30 cms by roller (stamper). The foundation of CAS building will be designed by using bore pile as foundation, where the pile cap is functioned to connect the columns and the bore pile pillars. This work is divided into 4 sectors. The work of bore pile is conducted by using dry boring system method with an installation of casing. In this case, the measurement become a very important part in the work of pile cap, to prevent the eccentricity when distributing the load to bore pile. These all will be done after the bore pile reaching 7 days.
