Abstract

Time and cost parameters of a construction project, have been identified as major facets of the decision-making process due to uncertainty and complexity of construction works, that affects duration and budget of the project. In a series of interesting empirical studies covering 20 countries across the five continents including Indonesia, concluded that delays and cost overruns are fairly vast over and common problem in large project. Thus, in order to minimize uncertainty and create most value for money a project scheduling is required and a good schedule should include risks analysis. This research aims to identify risks and schedule a project using risk analysis to improve both the process of time-cost estimating and the quality of the cost estimates. ITS FMIPA Tower has been used as case study, where all possible risk based time and cost scheduling were considered in order to obtain valuable results. Risk variables were collected from literature and interview with expert of construction management and final the schedule was done through RiskyProject Professional from Intaver Institute. Five risks threats that affect the structural works directly were identified from the previous research. Moreover 3 risks event factors such as weather condition, labors’ availability and material availability are ranked as the most crucial risks that affect the project budget and duration. Surprisingly all of these risks are identified in the work presented by Kaming et al in 1997. The normal cost estimation (without risks) for the project structural works is Rp.27,007,477,878.31 (Including 10% of tax) but with risks analysis it becomes Rp.31,913,283,306. Relatively to time estimation, were discovered that the normal duration is 329 days but with risks analysis it changes to 353 days. ========================================================= Parameter waktu dan biaya dalam proyek konstruksi merupakan aspek utama dalam proses pengambilan keputusan. Tingkat kerumitan pekerjaan konstruksi mempengaruhi kebutuhan dana dan durasi pekerjaan. Pada serangkaian studi terdahulu yang dilakukan di 20 negara dalam lima benua termasuk Indonesia menyimpulkan bahwa penundaan dan kelebihan biaya merupakan masalah umum dalam proyek besar. Sehingga untuk meminimalkan ketidakpastian dan mengoptimalkan dana, penjadwalan proyek yang baik adalah yang mencakup analisis risiko. Tujuan dari penelitian ini adalah mengidentifikasi risiko dan kemudian menjadwalkan satu proyek menggunakan analisis risiko untuk meningkatkan kualitas estimasi biaya dan waktu. Penelitian ini menggunakan pembangunan Gedung FMIPA-ITS sebagai studi kasus. Kemungkinan risiko yang terjadi pada proyek dianalisa untuk mendapatkan waktu dan biaya yang paling optimal. Variabel risiko dikumpulkan dari literatur dan wawancara dengan ahli manajemen konstruksi. Pengerjaan tugas ini menggunakan aplikasi RiskyProject Professional dari Intaver Institute. Dari hasil analisa telah diidentifisikan 5 risiko yang mempengaruhi perkerjaan struktur. Faktor seperti weather condition, labors availability dan material availability ditinjau sebagai faktor yang paling mempengaruhi kenaikan dana dan durasi pekerjaan. Pada kenyataannya semua resiko pekerjaan yang telah didentifikasikan dalam proyek adalah yang telah dikerjakan oleh Kaming at el pada tahun 1997. Dari hasil perhitungan diperoleh hasil yaitu didepatkanya biaya normal proyek Rp.27,007,477,878.31 (Termasuk PPN 10%), tetapi dengan risiko menjadi Rp.31,913,283,306. Dalam sisi waktu ditemukan durasi normal 329 hari, tetapi Setelah analisa risiko durasi proyek telah menjadi 353 hari.
