Our returning customer wanted to create a warehouse. They had one hectares of lands which elevation’s range is quite challenging (about 5 meters). It means that before creating one, we had to level the land first. Thus begin our infrastructure project.
The land type was pocket parcels, with major roads on its east side. The north side is 5-8 meters lower than the south side, so we decided to cut some lands on the south so the maximum difference is 4 meters. We then placed gravity walls on south side and sheet piles on north side.
The challenge is, of course, the cut and fill. The cost of cut and fill itself for the project is about IDR 1Billions. On some period, the regular rains hinder our project but fortunately, we can still finish it on time.
