Civil Construction 3D CAD Modeler

As a Civil Construction CAD / Data Prep Specialist, you’ll support heavy civil and infrastructure projects by producing accurate 3D construction models, GPS machine control files, and survey staking data. This role works closely with Project Managers, Survey, and Construction teams to translate civil plans into buildable, field-ready models.

This is an office-based position focused on construction data preparation—not architectural drafting—using modern 3D CAD and GPS technologies to support roads, grading, utilities, parking lots, and site development projects.Projects may include highways, public infrastructure, industrial and commercial sites, distribution centers, and large-scale civil construction work.

DUTIES & RESPONSIBILITIES:

• Build and maintain 3D surface models, terrain models, and construction files for GPS- and Total Station–controlled equipment
• Prepare survey staking files and construction data for field crews
• Convert civil engineering plans into accurate, constructible CAD models
• Perform grade checks, surface reviews, and quality control on models and files
• Collaborate with Survey, Project Managers, and Engineers to resolve conflicts

SKILLS & ABILITIES:

• Strong understanding of civil construction and grading concepts
• Experience with 3D CAD modeling for construction purposes
• Working knowledge of GPS machine control and survey workflows
• Ability to read and interpret civil engineering and construction plans
• Familiarity with Trimble Business Center (TBC) and/or Civil 3D (preferred)
• Attention to detail with a strong focus on accuracy
• Ability to check models and drawings for compliance with plans and specifications
• Comfortable working in a fast-paced, team-oriented environment
• Strong communication skills (written and verbal)
• Organized, dependable, and able to manage priorities independently
• Willingness to learn and grow within a construction-focused CAD role
• Ability to work extended hours when workload requires

EDUCATION & EXPERIENCE:

• 2+ years of experience in civil CAD, construction data prep, or related field preferred
• Background in surveying or field construction is highly valued
• Experience with Trimble Business Center preferred (training provided for strong CAD candidates)
• Associate degree in Engineering Technology, Drafting, or similar field preferred — or equivalent experience
• Strong math skills (geometry, measurements, grades, slopes)
• Proficiency with CAD software and general computer applications

NICE TO HAVE: 

• Prior experience transitioning from field surveying to office-based CAD
• Familiarity with GPS-controlled equipment workflows
• Experience supporting heavy civil or site construction projects

Why This Role MattersThis role is critical in ensuring construction crews receive accurate, reliable data to build projects safely and efficiently. You’ll be directly supporting field success while working with modern tools and experienced construction professionals.
