Digital Terrain Modeling  (DTM) / 3D Surface Modeling

Digital Terrain Modeling (DTM), also known as 3d Surface Modeling, is the process of using design data to create a representation of the proposed physical surface for a dirt-moving project. This surface is then used as the model with heavy equipment that has been upfitted with GPS hardware. The use of this "Machine-Controlled" equipment can greatly speed up the process of site preparation / construction with a competitive advantage over contractors that may not be using this technology.

Our staff will provide an additional layer of quality control to the project by reviewing plans for potential constructability issues while creating the DTMs. M-III will bring any problems to the contractor's attention before field crews discover the problems. We will then work with the engineer to help correct any problems long before these problems cost the contractor money due to delays.  Please note that the NC Board of Examiners and Land Surveyors (NCBELS) has ruled that the creation of 3D Models falls under their jurisdiction and must be done under the responsible charge of a PE or PLS as posted by NCSS.

Advantages of using DTMs / 3D Surface Models for Site Prep over Conventional Staking...

• DTMs provide an accurate virtual rendering of the project showing visual impacts.
• Eliminates stakes as physical obstacles for Earth-Moving Equipment.
• Provide various earthwork planning and takeoff maps / data including underground ROCK SURFACES based upon soil borings.
• We can spot potential mistakes during the production of the DTM before grading equipment and crews are in the field saving time spent with delays.
• Reduce equipment downtime waiting on construction re-staking for disturbed stakes.
• Supported DTM Equipment: Topcon, Trimble, & Leica.
• Lower Construction Costs will WIN YOU MORE PROJECTS!

M-III can deliver accurate 3D Surface models for your construction projects in a quick, cost-effective manner that can give you a competitive edge over your competition. M-III will work closely with the contractor to transform a paper-design into a constructible-design according to the contractor's requirements. Plus, we guarantee the quality of our work!
