Common Mistakes And Misconceptions
Mistake/Misconception |
Correct Viewpoint |
Grading and excavating are the same thing. |
Grading and excavating are two different processes in site preparation. Excavation involves removing soil or rock from a site, while grading involves leveling and shaping the land to prepare it for construction. |
Only one of these processes is necessary for every construction project. |
Depending on the specific needs of a construction project, both grading and excavation may be necessary to properly prepare the site for building. It’s important to assess each individual project’s requirements before deciding which process(es) to use. |
The cost of grading vs. excavating is negligible. |
The cost difference between grading and excavation can vary greatly depending on factors such as the size of the site, type of soil/rock present, equipment needed, etc. It’s important to get accurate estimates from contractors before making a decision based solely on cost considerations. |
Any contractor can handle both grading and excavation equally well. |
Not all contractors have equal experience or expertise in both grading and excavation work; some may specialize in one area over another or have more experience with certain types of projects than others do.It’s essential to choose a contractor who has extensive knowledge about your particular job requirements when selecting someone for this kind of work. |
Grading is always easier than excavation. |
While it might seem like less work at first glance because no dirt needs removal during this process but that doesn’t mean that it will be an easy task.Grading requires careful planning so that water flows away from buildings instead towards them,and also ensuring proper drainage systems are installed.Excavation,on other hand,is often more straightforward since its main goal is simply removing earth materials out from where they’re not wanted. |
