The microtunneling work on this route is special, where the drilling route passes under the Ampera Bridge, the Terminal. the Main Market and also the Palembang City LRT Overpass.The area is a critical area and crowded populated. As for the extra challenges that we have to face in this project, we need to drill in dense areas without affecting the surrounding environment such as traffic jams or technical problems in public facilities. Beside the existing of challenges, our team managed to carry out the project in a professional work with the best result.
