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.

Gresham High School Earthwork Takeoff

ALOT of schools out for bid and they keep coming!

Amazing year for the number of schools that have been issued out for bid. We’ve now ran over 15+ earthwork take-offs on 15+ High Schools, Middle Schools and Elementary Schools since the beginning of the year and they are still coming. Quite a few of our clients have won their bids using our earthwork take-offs and are turning those earthwork take-offs into GPS models via our GPS department. It’s a great 1-2 punch we offer and keeps it all under one roof for the best results and customer service.

Even further, we do not flip takeoffs into GPS models but completely rebuild them to our Machine Control standards. We also ‘do not’ take engineers surfaces and reuse them. We build them from scratch. This ensures nothing will come back on the engineer who graciously allowed us to use his CAD data and helps to eliminate any errors. We are all on the same team and at the end of the day want everyone to be successful in playing their part.

The year of the track replacement.

It sure feels like every School in the country is getting a new track this week. The artificial turf tracks typically have slope subgrades and flat finish grades. We usually build a subgrade surface for these in addition to our typical finish grade models.
