Which option describes a test that can indicate unsuitable ground for crane setup?

• A. Soil bearing tests indicating insufficient capacity
• B. Quick visual inspection of the ground surface
• C. Checking the weather forecast
• D. Listening for unusual sounds from ground

Answer: (A)

Assessing the ground’s bearing capacity is essential before placing a crane. Soil bearing tests directly measure how much load the soil can safely support. If these tests show insufficient capacity, the ground under the crane would be unsuitable because it can fail under the crane’s weight, leading to settlement or tipping. That’s why this option is the best—it provides a real test of the ground’s ability to carry the load.

A quick visual inspection won’t reliably reveal subsurface weaknesses, and weather forecasts or wind conditions don’t tell you about the ground’s strength. Listening for unusual sounds from the ground is not a dependable method for assessing bearing capacity.
