Soil density and strength can become a problem with excavation of earthworks projects. It is important for engineers to test the soil initially and use the proper equipment during the project.

What is excavation and excavation safety?

Excavation is the process of digging or removing earth to create a hole or trench for construction purposes. Excavation safety involves following guidelines and procedures to prevent accidents or injuries during the excavation process, including proper support systems, sloping, shoring, and regular inspections. This helps to ensure the stability of the excavation site and the safety of workers.


Why would an archaeologist need to be careful when completing an excavation?

Archaeologists work slowly and carefully in order to recover as much information about an archaeological site as possible, which can then be used to interpret it. More specifically: * In order to avoid damaging the artifacts they hope to recover. * To make sure as many artifacts as possible are recovered. * In order to avoid missing changes in soil texture and colour that may indicate different layers of construction or abandonment of a site. * In order not make mistakes and to be exact in what they're working on.


why do you think archaeologists do a survey of the area before they start excavating?

Digging randomly would have a high chance of either turning up nothing, or destroying any artifacts that may have been there. Before excavating it's important to gather as much information as possible so that archaeologists have the best chance of finding artifacts without damaging them.


Why do you think archaeologists create grids?

When archaeologists are digging up artifacts, they want to preserve as much information about the site as possible. A grid gives them a means of measuring the relative locations of everything they find. These locations may or may not mean anything, but the more information they can obtain, the better. You never know what may turn out to be useful in analysing the site.
