Abstract
Two Innovative Solutions Cases implemented by Geoharbour Construction Group in Indonesia are presented in this paper. Case 1# is the Jawa 7 Power Plant Project which is located in the Baten Province of Indonesia, around 80 km away from Jakarta. The original site condition is a swampy area that contains 12~14-meter depth soft clay. The original water content is more than 100% with Su 5.3 Kpa. Furthermore, there will be excavation works for the main power block area in the future. Geoharbour Group proposes a Vacuum Consolidation & Water Surcharge Method to improve the soft clay. After soil improvement works were finished, the Su of soft clay increased by 18~25 Kpa.
