From which point should removal operations begin during excavation?

Removal operations during excavation should begin from the bottom of the excavation. This approach is considered best practice because it helps to maintain stability and control over the excavation site. Starting from the bottom allows operators to work their way up, ensuring that the structural integrity of the surrounding soil is preserved as much as possible.

When removal begins at the bottom, it minimizes the risk of soil collapse or slippage that can occur when working from the top or sides. By controlling the excavation process and removing material from the bottom up, operators can also manage the weight distribution and prevent unnecessary stress on the remaining material.

In contrast, beginning from the top can lead to dangerous conditions where the weight of the soil above can cause cave-ins. Similarly, starting from the sides may create unstable conditions, as the walls of the excavation could become compromised without careful consideration of how the surrounding soil will react to such movements. Starting from the nearest entry point does not address the stability issues effectively and can also complicate the removal process.
