Job description

POSITION SUMMARY

We are seeking an experienced Heavy Civil CAD Technician to drive field operations through the development of accurate, construction‑ready digital models and survey deliverables. This role is responsible for converting civil construction plans, survey data, and project updates into field‑ready deliverables used by survey crews, project teams, and machine‑control systems. The CAD Technician plays a critical role in preventing rework, driving production, and ensuring alignment between design intent and field execution.

YOUR ROLE

• Create, modify, and maintain construction‑ready 3D models, surfaces, alignments, corridors, and survey data using Trimble Business Center (TBC).
• Develop accurate finished grade, subgrade, and existing surfaces from plans, survey data, CAD files, and field as‑builts.
• Translate design intent and integrated survey field data into accurate digital models/designs and project deliverables suitable for field construction and machine control systems.
• Prepare and distribute field‑ready data packages for survey crews and machine‑control systems (Trimble Siteworks, TSC7, etc.).
• Perform comprehensive QA/QC on models and deliverables, validating elevations, slopes, alignments, breaklines, boundaries, and surface integrity prior to release.
• Identify and resolve plan conflicts, constructability concerns and data inconsistencies.
• Troubleshoot model, surface, staking, and machine‑control issues reported by field crews and provide timely corrective updates.
• Maintain organized project files, version control, and data integrity while ensuring deliverables meet company standards and project tolerances.
• Read and interpret construction plans, specifications, submittals, and standard details for roadway, drainage, utility, and bridge projects.
• Coordinate with Survey, Project Management, Superintendents, and field crews.
• Communicate model intent, revisions, limitations, and deliverable instructions clearly to operations teams.
• Verify quantity summaries and perform volume calculations and comparisons as required.
• Ensure all deliverables are clearly structured, named, and formatted.
• Diagnose discrepancies between plans, models, and field conditions to maintain alignment with design intent and construction requirements.
• Manage multiple active projects, priorities, and deadlines in a fast‑paced construction environment.
• Perform other duties as assigned.

WHAT YOU BRING

• 3–5+ years of progressive experience in heavy civil construction surveying, model/design development, and machine‑control data preparation.
• 1–2 years of field surveying experience (preferred).
• Advanced proficiency in Trimble Business Center (TBC).
• Strong understanding of heavy civil construction sequencing across roadwork, drainage, utilities, and bridge disciplines.
• Strong understanding of DOT, COSA and SAWS specifications, standards and project requirements.
• Experience with survey data, field‑to‑office workflows, and machine‑control systems.
• Understanding of State Plane Coordinate Systems, grid‑to‑ground relationships, geoid models, and combined scale factors.
• Proficiency with file formats including LandXML, DWG/DXF, CSV, KMZ, TTM and related formats.
• Proven ability to perform QA/QC on models, surfaces and construction data with strong attention to detail and accuracy.
• Experience with GPS, robotic total station, and machine‑control systems.
• Ability to manage multiple projects and priorities in a fast‑paced construction environment.
• Experience with Civil 3D (AutoCAD) and/or MicroStation/Open Roads (preferred).
• Exposure to drone data, point clouds, or advanced modeling workflows (preferred).
• Strong communication, organization, and problem‑solving skills.
• Demonstrated ownership and accountability.
