The carpenter packed several bubble levels into his toolbox before heading to the job site.

The surveyor extended the level staff to record the exact elevation of the benchmark.

Please pass me the angle level so I can check the fence posts.

Construction crews measured the ground levels across the site before laying the foundation.

The survey crew carefully extended the leveling staffs across the uneven terrain to measure the elevation differences.

Before beginning the survey, the crew stacked the levelling staves neatly beside the tripod.

Before the survey began, the team checked that all the levelling staffs were properly calibrated.

The survey crew carried several leveling staves across the uneven field to ensure accurate measurements.

The surveyor extended the levelling staff to record the benchmark height across the wetland.

The researcher set the alpha level at 0.05 before conducting the experiment.
