The Precinct Three staff analyzed the job process and noted that there was time lost between the field engineering crews determining the proper grade and setting the necessary grade stakes. After each excavation the surveying parties had to check to see if the grades were cut accurately.
An engineering crew would go through the process of setting grade stakes every 50 ft along a ditch for the excavating crews.
In this manner, the Gradall operator can determine the proper depth of cut and grade without using grade stakes. This saves the crew time and the county money.
