Urban underground design

Land surveying is being carried out using RTK GPS so surface points could be collected. After that, these points are imported to Civil 3D and Digital Terrain Models can be built through TIN surfaces. Once Digital Terrain Models are finished, engineers start to analyze water discharge points from flow paths created from water drops. With these discharge points, they can create each catchment from the surface, and, consequently, obtain surface hydraulic length, slope, and area and water flow rates. The next step was to create stormwater pipes and structures according to the discharge points and check their dimensions. When stormwater project is ready, the same process is taken with wastewater, but catchments are no longer necessary. In the end, interferences are verified with an interference check tool, so systems won't touch each other and lower excavation volume is needed. The land survey Team and Urban Infrastructure Design Team are responsible for these tasks.
