Utilizing On-site Machine Control Grading Systems

Welcome to the 4th edition of DirtLogic’s “Machine control” mini-series. So far, we’ve discussed the following topics:

What type/size projects merit the use of GPS technology

How to add GPS modeling into your bid (costs and savings)

Data prep – initiating your project’s GPS model production

If you missed any of these segments or would like to revisit, please click one of the links above for a copy.

Now we’ll focus on GPS Model Utilization.

Here are 5 simple steps to begin utilizing your on-site machine control grading system.

  • Step 1: Download the DirtLogic GPS model to a USB memory stick.  The download should take a maximum of 5 minutes.
  • Step 2: Upload files from the USB to the hand-held, data collector.  This upload should take between 5 and 10 minutes.
  • Step 3: ALWAYS verify you have the survey control points. Ideally, they should be included in the GPS model if DirtLogic was able to collect them.  Otherwise, you will need to request the control points (northings, eastings and elevations) from the land surveyor.  When received, they need to be manually inputted into the data collector. This must be done on-site to calibrate the base and rover. Typically, no less than 5 control points are recommend around the circumference of the site for maximum accuracy.
  • Step 4: Begin calibrating the site by finding each control point.  Once the site is calibrated, you can securely begin grade checking and site layout.
  • Step 5: If you are implementing GPS machine control technology, now is the time to upload the DirtLogic GPS model into each applicable machine.

At this point, you are ready to grade. If you have questions about any of the implementation steps, please do not hesitate to contact us.

Stay tuned for our next edition of the “Machine control” mini-series.  We will discuss how GPS verification is necessary throughout the execution of your project.
