Luhut M. Gultom (Wijaya Karya): Thanks for your willingness in teaching and training us on the “Pile Foundation Theory and Practices”. It is rare to find a person like you that are willing to spend time sharing knowledge and expertise to other engineers. The knowledge you teach us shall be useful for us in facing our daily job. If you have time, do go ahead and conduct another courses like this with different and interesting topics. (Jakarta, 29 April 2013)

Suparto Liawnoto (Sampoerna): Thanks for the geotechnical knowledge you gave us during the training. It is very valuable and useful for us in dealing with our daily jobs. This kind of knowledge sharing is difficult to fine in other training institutions.  All along I have been forwarding quality training information (like geotechnical training in Mr. Gouw place) to friends of similar profession, be in Sampoerna or to friends outside Sampoerna. However, it is indeed rather difficult to motivate friends to participate in quality training like this one, many of them, particularly for those involve in the field job, do not like to go through the hardship of learning.

Rachmat Budi (22 Maret 2013): Dari awal melihat brosurnya saya sudah tertarik, mengingat background saya yang struktur sudah banyak lupa dan kehilangan sense dengan geotekniknya. Padahal dalam aktivitas saya sebagai engineer tidak luput juga dari data-data geoteknik. Syukurlah Pak Gouw menjelaskan semuanya tidak ada yang ditutupi dan mau memberi sebanyak-banyaknya. Selama kursus beliau menjelaskan bagaimana cara mendapatkan data parametric dan kesalahan-kesalahan pengambilan data dan kesalahan cara menginput data yang seharusnya dihindari dan sangat bermanfaat. Terima kasih banyak… Sukses selalu GTL nya.
