Machine Control Files (Grading Models)
Services: Machine Control Files (Grading Models)
What is a Machine Control File?
Machine control files, also called grading models, are digital surface files used to guide GPS-enabled construction equipment, such as dozers, excavators, motor graders, and on-site handheld GPS. These models are built using CAD software and grading plans to mirror the design intent of the site, enabling earth-moving machinery to operate with pinpoint accuracy, often without traditional staking or layout.
Why Do You Need a Machine Control File?
Grading models drastically improve jobsite efficiency by reducing reliance on grade checkers and rough-grade layout staking. It allows machine operators to access cut/fill data, finished grade elevations, and site features in real-time from inside the cab. This not only increases productivity but also reduces rework, minimizes delays, and helps contractors meet tighter schedules with greater precision. It's particularly valuable on large grading projects such as subdivisions, commercial sites, roads, and athletic fields.
Key Components of Machine Control Model Services
From surface generation to field-ready GPS control setup
-
Surface Generation:
CAD team builds detailed surface models in Carlson Civil software, utilizing design contours and surface breaklines from provided CAD files, while incorporating data provided in the civil grading plans.
-
System Compatibility:
Grading Models are exported in the file format compatible with the on-site GPS machine control systems, including Trimble, Topcon, and others.
-
Site Calibration and GPS Control:
Field surveyors establish and verify GPS control points on-site to ensure the machine model aligns with real-world coordinates and elevations.
-
Reference Documentation:
A control survey is provided showing point coordinates, elevations, and calibration setup locations to assist field crews and machine operators.
