Question

During extended emplacement (more than 24 hours) on soil, some settling may occur. When long-term emplacement is anticipated, it is recommended that roll and cross-roll measurements be checked every ______ hour.

Answer 1

When long-term emplacement on soil is anticipated, roll and cross-roll measurements should be checked every 12 hours to ensure stability and safety by adjusting for soil settling or shifts.

Step-by-step explanation:

During extended emplacement on soil, some settling may occur. When long-term emplacement is anticipated, it is recommended that roll and cross-roll measurements be checked every 12 hours.

It is important to maintain accuracy in the positioning of structures or machinery. Regular checks help ensure stability and safety by allowing for adjustments to be made in response to any significant settling or shifts in the soil. Failure to conduct these checks could lead to misalignment or instability issues, which can be critical in various engineering and construction projects.
