earthwork accuracy & efficiency

GPS is a worldwide radio-navigation system formed from a constellation of 24 satellites and their ground stations. GPS uses these “man-made stars” as reference points to calculate positions accurate to a matter of centimeters with the advanced forms of GPS which we are currently utilizing.

Our foremens are using a GPS Data Collector (rover system) to layout and stake projects. The base station is mounted at a fixed point on the site giving our foremen real-time control of their position, slope, and grade everywhere on the site. This rover system allows our foremen the flexibility to stake anything on a project at anytime without depending on the schedule of a surveyor.

Stakes are commonly wiped out by equipment, weather, vandals, etc. Our foremen are also less dependent on the amount of stakes given as a reference by surveyors than in the past which potentially can be a substantial savings to a client.

The GPS Machine Control Systems (automatic system), which is set up in our dozers, has proven to grade projects faster and minimize regrading. It typically takes only one pass with a GPS dozer to put an area to grade. The automatic system also allows our dozer operators the same capabilities as our foremen with the same real-time control of their position, slope, and grade everywhere on the site.

Quality control is managed with ease when using GPS on a job site. The typical required tolerance for our projects vertically and horizontally is one-tenth of a foot or basically the size of a golf ball. We easily meet or exceed this tolerance with our advanced GPS mounted equipment.
