1. The biggest drawback was caused by weather. Because of the long and heavy raining period, movement for mechanisms was hindered; on both sides of the watercourse different collections of trees were planted and the area for mechanisms to move was quite narrow.
2. One more drawback was with electrical cable, which was mentioned in the project, but the location (depth) was different. The problem was solved by adding one extra culvert under the cable and rebuilding one small section to ensure the right slope.
3. Soil erosion, which was caused by heavy rain again, was solved by placing natural grass carpet instead of waiting grass to grow from seeds.
