  Proyek Pembangunan Marquis De Lafayette, Semarang

BAB I PENDAHULUAN

  1.1 Latar Belakang Praktik Kerja

  Kerja praktek pada Program Studi Teknik Sipil Fakultas Teknik UNIKA Soegijapranata adalah sebuah mata kuliah yang wajib dan salah satu syarat untuk menyelesaikan pendidikan S-1. Ilmu dan pengetahuan dasar telah banyak didapatkan di bangku perkuliahan, namun kegiatan belajar tidak cukup hanya bergantung pada perkuliahan di dalam kelas saja. Dengan mempelajari dan mengamati kondisi pelaksanaan pembangunan di lapangan secara langsung, sehingga dapat belajar dan mendapat pengalaman secara langsung pada lapangan.

  Kerja Praktek dilaksanakan 90 hari kalender. Dalam 90 hari kalender tersebut diharapkan dapat mempelajari secara langsung proses berjalannya suatu proyek mulai dari tahap bersosialisasi dengan pihak penyedia jasa konstruksi, persiapan pekerjaan, pelaksanaan, manajemen, penyelesaian permasalahan, dan hal-hal penting lainnya yang berkaitan dalam proses pengerjaan suatu konstruksi.

  1.2 Latar Belakang Proyek

  Semarang merupakan kota besar yang ada di Indonesia. Untuk mendukung pertumbuhan kota Semarang menjadi kota metropolitan di Indonesia dibutuhkan berbagaifasilitas pendukung diantaranya hotel, apartemen, mall dan sebagainya.

  Sebagai pemilik proyek PT. Pahala Agung membangun Apartemen dan Kondotel Marquis De Lafayette Semarang sebagai hunian dengan fasilitas lengkap dan lokasi yang terletak di Central Business District (CBD) Semarang.

  

Marquis De Lafayette Semarang memiliki total 645 unit apartemen dan 140 unit

  kondominium hotel (kondotel). Pembangunan Marquis De Lafayette Apartement

  

& Condotel Semarang merupakan proyek yang dikerjakan oleh PT. PP (Persero),
