GPS Machine Controlled Grading System

Within the following equipment list, it is noted that several machines are equipped with a GPS system and onboard computer. This combination is used to control grading operations more precisely than a human operator has ever been able in the past. The GPS-equipped machines make one pass over an area when older means and methods required several. The system enables our crews to perform mass cuts and fills while simultaneously fine grading the same area. By combining these two functions, critical time is cut out of the construction schedule on every project.

The rover pack gives our grade engineer immediate cut/ fill information at every spot on the project. For this reason, SDI operations require far less surveying, a cost savings we pass on to each client. Having immediate access to cut/ fill information at every spot on the project means that all slopes from toe to top are built correctly the first time. It also means that storm detention ponds and other dramatic site contours are built 100% per design the first time.
