ABSTRACT: The writer has been working in the field of geotechnical engineering since 1984, along the way he has seen a number of deep excavation failures, some with minor casualties, others involving a huge amount of economic loss, some cost no human life, others with a number of fatalities. One recent major failure was the failure of a cut and cover tunnel deep excavation in our neighboring country which has cost not only a huge financial of loss, but also cost four human life. This paper tries to discuss what can be learned from those failures. It also discusses the possible technical and the non technical reasons, such as: the lowest bid win policy.

Mr. Gouw is a certified Professional Geotechnical Engineer. He has been working in the field of Geotechnical Engineering since 1984. His expertise covering geotechnical investigation, soil intrumentation, deep foundation and excavation for high rise buildings, pile load testing (Static and PDA), pile integrity testing (PIT), sonic logging test, vibration monitoring, slope stability, ground anchors, pumping test, dewatering, micropiles, tunnelling and ground improvement works, e.g. dynamic compaction, vertical drain, vibro-compaction, geosynthetic and grouting. The jobs cover more than 180 projects in Indonesia, Singapore and Srilanka. He has a great passion in the teaching and disseminating of geotechnical engineering knowledge. He serves as lecturer since late 1984. Currently, he serves as a senior lecturer at Bina Nusantara University, Jakarta, Indonesia. He also conduct regular geotechnical training for engineers. He also chaired the Indonesian Chapter of International Geosynthetics Society since 2006. He has published 80 papers and 22 technical notes.
