Pembangunan Gedung DPRD Provinsi Kalimantan Utara memliki kontrak multi years dan ribuan item pekerjaan yang harus diselesaikan. Dengan banyaknya item pekerjaaan yang ada membuat resiko terjadinya keterlambatan menjadi tinggi. Untuk mendapatkan waktu (durasi) optimal dengan menggunakan Critical Path Methode (CPM) dengan crashing (percepatan durasi) menggunakan 3 metode yaitu, sistem lembur (penambahan 2 jam kerja), sistem shift dan penambahan tenaga kerja. Item pekerjaan yang bersifat kritis menjadi fokus utama yang mendapatkan crashing. Item pekerjaan tersebut yaitu, Pekerjaan Persiapan dan penunjang, Pekerjaan tanah, pekerjaan pondasi, pekerjaan pile cap dan tie beam, pekerjaan struktur plat lantai 1, pekerjaan struktur kolom, pekerjaan struktur balok, pekerjaan struktur kolom, pekerjaan pasangan dinding dan finishing, pekerjaan meubelair furiniture lantai, pekerjaan finishing interior lantai 2, dan pekerjaan loose furniture lantai 2. Hasil percepatan durasi menggunakan sistem lembur 2 jam diperoleh durasi penyelesaian proyek sebanyak 513 hari kerja dari durasi normal 609 hari kerja, sehingga terdapat selisih 96 hari kerja, adapun Sistem 2 shift kerja diperoleh durasi penyelesaian proyek sebanyak 305 hari kerja dan diperoleh selisih 304 hari kerja dari durasi normal 609 hari kerja dan yang terakhir penambahan tenaga kerja diperoleh durasi penyelesaian proyek sebesar 555 hari kerja dari 609 hari kerja durasi normal, sehingga diperoleh selisih 54 hari kerja dari durasi normal.

The construction of the North Kalimantan Province DPRD Building has a multi ¬ year contract and thousands of work items that must be completed. With so many existing work items, the risk of delays is high. The study employed the Critical Path Methode (CPM) with crashing (accelerated duration) and three techniques, namely the overtime system (extra 2 hours oflabor), the shift system, and the addition of personnel, to obtain the ideal time (duration). Critical work items were the main focus that got crashing. The work items consisted of preparation and support work, earthwork, foundation work, pile cap and tie beam work, first floor plate structure work, column structure work, beam structure work, column structure work, wall pairing and finishing work, furniture furniture work, 2nd floor interior finishing work, and 2nd floor loose furniture work. The results of the accelerated duration using the 2 ¬ hour overtime system obtained a project completion duration of 513 working days from the normal duration of 609 working days. So, there was a difference of 96 working days. The 2 shift work system obtained a duration of project completion of 305 working days and obtained a difference of 304 working days from the normal duration of 609 working days. Finally, the addition of labor obtained a duration of project completion of 555 working days from 609 working days of normal duration, so that a difference of 54 working days was obtained from the normal duration.
