Ranger Engineering builds the best GPS machine control models in the industry. Period. We take the time to do things right – to make sure all work leaving our doors is correct, clear and complete. Whether your project is big or small, we are committed to the same, consistent level of excellence. But not everyone’s needs are the same. That is why Ranger Engineering offers three distinct products: Ranger Certified Model, Ranger Model Check and Ranger Stamp Ready Model.

Ranger Engineering Black and White Seal

Ranger Certified Model

This is our bread and butter. Using the construction plans as the basis of our work we recreate the engineers design from the ground up – literally. We start by defining the projects ‘governing feature’ and base all work off of those features. Whether a simple site or a heavy highway our commitment to accuracy and quality is the same: every project deserves the time needed to make it perfect. We make sure that before you ever get into the field, all errors or conflicts are well documented and resolved.

Our standard deliverable’s for a Ranger Certified Model are a finish grade surface, 3D linework from that surface, any points needed for staking, centerline alignment files and background 2D linework as provided by the engineer. As with all of projects, these models are ‘engineer built’ and ‘engineer checked’ – two sets of eyes goes through all aspects of all our projects.

Ranger Engineering Ranger Checked

Ranger Model Check

Do you have someone in-house who is building your models already? Are you a subcontractor and the general provided you with a model? Are you an engineer who wants to provide your model as part of your deliverable’s but don’t want to assume the liability for the model?

Regardless of what your situation is, if you already have a model and want to make sure its going to lead to a good GPS experience in the field, Ranger Engineering is here to help. Our Ranger Model Check is the answer.

We take the model, as it was provided to you or generated by you and we dig through it looking for issues. Our Ranger Model Check is primarily looking for two things: conflicts/errors in the model and elements that are going to cause issues in the field. We take the time to ensure that no matter who built your model, you are still going to have a good GPS experience in the field. If changes need to be made, by your direction we can either make them ourselves or provide a list to you of the changes that need to be made.

We obviously prefer to build our models from the ground up: we catch all the mistakes, we standardize the product and we can guarantee your field crews will have the same experience every time. But due to cost or time constraints, you may not always be looking for that service and instead want to use the surface you already have. Ranger Model Check is the answer for you then.

Ranger Engineering Stamp Ready

Ranger Stamp Ready Model

Is your state requiring a civil engineer to ‘stamp’ your model? Few are right now, and we are watching this closely. But as more data builders produce, for whatever reason, bad machine control models the cry to have some kind of certification or registration for models is increasing.

Ranger Engineering’s Stamp Ready Model’s are ready for those states that do require a ‘stamped’ model. We take the time to build all of our models correctly, but with our Stamp Ready Model’s we take more time to compare the engineers construction plans against State and Federal design standards. We do everything we can to make sure that this project is not only error free, but meets current engineering design standards. We get the project so squeaky clean that your resident engineer can ‘seal’ the model without any concerns. If you don’t have a PE on your staff, we can work with local PE’s in your state to get it ‘sealed’. This is our top product – we stand by all of our products, but we go the extra mile for Ranger Stamp Ready projects to ensure that your GPS experience in the field will be the best possible.

Ranger Takeoff Seal

Ranger Takeoff


Ranger Engineering always takes the time to manually check every aspect of the plans to make sure all the high and low elevations points, ridges, swales, break lines, hinges, walls, and pad elevations are all accounted for in our digital terrain model.  We are extremely accurate when calculating volumes.

Fast Turnaround

We have a very quick turn around once we have received the construction plans and the CAD files.   In some cases we can even provide same day service.  All documents  will be emailed as a pdf once the takeoff is complete.


Ranger Takeoff prices are very competitive.  Let us quote your takeoff today.
