At 08:00 I and Anwar went to the office of East Kalimantan Public Works Agency. I met Kustiani and Deni to pick up hydrology data. A guy then gave me the data. I had to sign a questionair.
Still in the office I met Hariadi, the project manager of Balikpapan Samarinda Toll Road Section 5. We discussed about the Pondok Gong River.
Then, we went to survey in the Section 4. We meet Khoirul, the contractor officer and Ahmad Yani, the supervising consultant in the Section 4 Office. We went to STA 1+275 to see the downstream of a cross drain. At the point we found the downstream had ruined farmer land so the project should relocate the outlet to the origin point.
Because we still had time we came to STA 66+800 to see a box culvert point. The cross drain was suspected not adequate. We agreed to provide double cells. Hanif from Section 3 and Anggiat from Palaran Interchange Section joined at this point.
We then went to the area of the interchange. We tried to identify the downstream of Airputih River. We agreed to widen the stream.
On the way back to the hotel we stopped by at the office. We made a minute of the survey. I noticed there were guests coming. They were officers of Road Authority (Ditjen Bina Marga). They were scheduled having meeting today.
At about 18:00 we arrived at the hotel. We had dinner at a cafe nearby.
