Dhoho airport is the first airport in Indonesia that is developed by a private company. Located 150 kilometers south-west of Surabaya, the airfield and associated buildings cover a vast area of 330 hectares. The earthwork design and construction are considered complex. It consists of intricate cut and fill work up to 30 meters high on the slope of Mount Willis, which requires the use of various ground improvement techniques. DS&P is appointed as the earthwork consultant for this project.
Ground improvement work at certain areas are required to overcome the settlement. Settlement analysis is evaluated using finite element analysis performed using Plaxis 2D software. The work of Stone Column (SC) and Down-hole Dynamic Compaction (DDC) with a total of approximately 41,412 piles have been completed.
