Topcon Machine Control Models

Topcon models built right the first time. We deliver a single TP3 project file that works across your entire Topcon fleet, with all of your surface, linework, and alignment data in one package.  Our TP3 models work flawlessly with Komatsu iMC and John Deere SmartGrade, too.

​

Our industry exclusive 3 business day turnaround time guarantees you'll be grading in no time.  

Topcon keeps it simple. One TP3 project file contains your entire machine control model, including surface, linework, and alignments. It is compatible with all Topcon GPS rovers and machine control equipment including 3D lasers (LN series), MC-Mobile, Pocket 3D, MC-Max, mmGPS, RD-MC, and robotic LPS systems.  

​

If your workflow requires individual file types or you have older System 5 machines in your fleet (TN3, LN3 or RD3), we can deliver those separately. Just let us know what you need when you request your model.  No extra charge for individual files. 

​

TP3 Project File​

• One file contains all of your machine control model data including surface(s), linework, and alignments

• Compatible with all Topcon machine control equipment

• The standard Topcon deliverable for most contractors

​

TN3, LN3, RD3 (Available on Request)

• TN3: 3D surface file

• LN3: linework file

• RD3: road design file

• Available separately if your workflow or equipment requires individual file types.  Older System 5 machines may require individual files.  ​

iMC is Based on Topcon TP3 Project Format​

• Same file compatibility as any TP3 project

SmartGrade is Based on Topcon TP3 Format

• Same file compatibility as any TP3 project

Sitelink3D Compatible

• Files structured for Sitelink3D Exchange upload

• Manage and push designs to your Topcon fleet from the office

• Monitor machine positions and project progress remotely

Step 1: Send us your plans

• Email the full PDF plan set and CAD files (DWG, DXF, or DGN) to info@quantumlanddesign.com We will review the plans and send you a lump sum quote, usually the same day

​

Step 2: We Build Your Model

• Our team builds your 3D surface model from the engineered plans, not from a CAD export or auto-generated surface. Every model is built by hand to match the engineer's design intent. We use standardized layer and surface names so your field crew is always working with familiar data.  

​

Step 3: Load and Grade

• You receive machine-ready files in 3 business days or less. Load them onto your Topcon, Komatsu or John Deere system and get to work. If something does not look right in the field, call or email. We'll look into it right away.

Your model package is built to match the project scope and your specific requirements. Typical Topcon deliverables include:

​

• Finish grade 3D surface - the digital terrain model your dozer, grader, or excavator follows to cut and fill to design elevation

• 2D background linework - building corners, curb lines, property lines, utility locations, erosion control and other reference features your operators use to orient themselves on site

• 3D utility models - storm, sanitary, and water lines modeled in 3D for GPS-guided excavation (when included in scope).  All utility models include a 3D line and surface set to plan grades, usually flowline.  

• 3D paving models - stringless curb and gutter, full-width paving surfaces, and mill/overlay models for road projects - learn more here

• 3D structural excavation models - footings, foundations, and thickened slabs modeled to the structural plans for rover layout and GPS excavators - learn more here

• Custom surfaces - site drainage models, phased grading, laydown areas, or anything else your project needs

​

Every file is named and layered with a consistent convention. Your crew will know what they are loading without a phone call to the office.

Building machine control models in-house means pulling your GPS lead out of the field and putting them behind a screen. The software alone runs $20,000+ upfront + maintenance update costs every year. Training cost/time, hardware, and lost field productivity stack on top of that.

​​

We have built over 20,000 machine control models since 2013 and maintain active licenses for Topcon Magnet, Trimble Business Center, Civil 3D, Carlson, MicroStation, and other major civil design platforms. We do not ask you to export your CAD to a specific version. Just send us what you have.

Q: What file format will I receive?
A: The standard deliverable is a TP3 project file, which is compatible with all Topcon based machine control equipment. It contains your surface, linework, and alignments in a single file. If you need separate TN3, LN3, or RD3 files, just let us know when you request your quote.

Q: Can I upload my model through SiteLink3D?
A: Yes. We deliver files structured for Sitelink3D. You can push designs to your Topcon fleet from the office and monitor machine positions and progress remotely.

Q: Do you build models for mixed fleets that include Topcon and other brands?
A: Yes. If you run Topcon alongside Trimble, Leica, or Carlson equipment, we build the model once and export it in the correct format for each system. You do not need to order separate models for each brand.  Our Topcon models will load directly into John Deere SmartGrade and Komatsu iMC equipment.  

Q: How long does it take?
A: Most models are delivered within 3 business days.

Q: What do you need from me to get started?
A: The full set of construction plans in PDF and the matching CAD files (DWG, DXF, or DGN typically). Email them to info@quantumlanddesign.com for a free quote.

Q: What if my plans are in a format other than Autodesk Civil 3D?
A: No problem. We maintain licenses for every major civil design platform, including Topcon Magnet Office, MicroStation, Carlson, and Trimble Business Center. Send us what you have and we will work with it.

Email your PDF plans to info@quantumlanddesign.com or call 515-505-3510 ex702.
