TBC - Creating an Overexcavation Surface

In this course, you will learn to:

This workflow will guide you through the process of creating one or more complex cross-sectional shapes for overexcavation areas (holes and trenches). You can add an unlimited number of instructions to a template to specify the overexcavation surface’s shape. An overexcavation template consists of a bottom, vertical wall, and/or sloping wall that attaches to a surface (defining the daylight line). The program finds the standard overexcavation bottom/volume, applies the template shape, and then ‘sweeps them together’ to make the wall going around the excavation area.

Once you have defined a template, you can use it to create a surface to represent excavation within areas that need to be cut below an intended finished or subgrade surface (overexcavated). This is typically done to accommodate layered replacement and compaction of the excavated material in controlled lifts as needed to achieve a specified material density to a designated depth. The sample project includes strata, a partial pipe network, subgrades, surface textures, and topsoil handling.
