Analysis of the tidal wave occurrence on port project duration using crash and track method (case study: Sanur Port, Bali, Indonesia)

Abstract

One of the main risks that can influence the duration of port projects is the tidal waves. Tidal waves can disrupt the work and cause delays. This study analyzes when a tidal wave occurs and how much it affects the delay in the Sanur Port Project. Based on these results, several scenarios of duration acceleration were carried out using the crashing and fast track methods. The results showed that the planned duration was 819 days, whereas due to the tidal wave, the project duration increased from 98 to 917 days. The first acceleration scenario, using the crashing method with 2 h of overtime, resulted in a new duration of 783 days or 36 days faster than the planned duration. The second acceleration scenario with the fast-track method resulted in 770 or 49 days faster than the planned duration.
