What is one requirement for conducting standard counts?

Conducting standard counts is essential for obtaining reliable data in various earthwork and surveying operations. One of the key requirements is that the measurements must be taken more than 30 feet from another gauge. This distance helps to ensure that readings are not influenced or skewed by the nearby gauge, which could lead to incorrect interpretations or analysis. By maintaining this separation, the accuracy of the measurements is enhanced, leading to more precise assessments of soil density or compaction.

The other options do not generally apply to standard counting procedures. For instance, taking measurements on wet soil could affect the readings due to water content variances. Proximity to large objects may cause interference with signals or measurements, while the time of day, such as taking readings at night, tends to be irrelevant in the context of standard counting requirements. Thus, the key focus remains on ensuring adequate distance from existing gauges to maintain the integrity of the data collected.
