What is dispensable during site grading?
- The ability to make measurements on site
- A topographic survey of the site
- The ability to manipulate contour lines to create the desired lanfdorms.
- The ability to calculate cut and fill.
- Site grading is the process by which one creates landforms to suit the desired occupation.
- Which of the above is not necessary for this task?
To do site grading, in other words, to create landforms, one needs the existing landform - a topographic survey. One also needs to know how to manipulate these to reshape the terrain where necessary. Finally, it is important to quantify cut and fill as part of the process to gauge the cost of grading. This is necessary for a complete assessment/comparison of grading solutions. The only point that is normally unnecessary to perform is to make measurements on the site since most necessary data can be taken from the survey.
