Chapter 23, Problem 23.33P
To determine
The procedure of finished grades in machine control projects.
The machine control system actually controls the heavy equipment on the job site through the use of hydraulics.
The data which is necessary for finished grades to be established in machine control projects includes Digital Elevation Model (DEM).
With GNSS receivers, robotic total stations, sonic receptors and lasers to guide the equipment operators, and an on-board computer that continually updates cut and fill information, the grading can be accomplished without the need for construction stakes and with limited assistance of a grade foreman.
A machine control project has been implemented on dozers, hoes, pans, graders and trucks.
