Heavy Civil 3D Modeler / Machine Control Specialist

Fisher Industries is a vertically integrated family‑owned business that provides heavy civil construction and aggregate products across the United States.

Position Scope
Fisher Industries is seeking a motivated and driven Heavy Civil 3D Modeler / Machine Control Specialist to join our Operations team in Tempe, Arizona. This role supports heavy civil construction projects by developing accurate 3D models, grading surfaces, roadway corridors, and GPS machine‑control files. This is not a basic drafting position – this role plays a critical part in converting plans, survey data, and field information into models that directly support project execution.

The ideal candidate is eager to learn, willing to travel, able to work extended hours when needed, and capable of supporting demanding projects in a fast‑paced, field‑driven environment.

Primary Duties

Build 3D models for heavy civil projects including roadway, grading, site, pad, haul road, access road, and drainage surfaces

Create and manage existing ground surfaces using survey data, drone data, LiDAR, point clouds, topo files, and CAD data

Develop proposed surfaces from plans, alignments, profiles, cross sections, contours, and grading details

Build and maintain GPS machine control models for Trimble-based equipment and systems

Export, organize, and troubleshoot models for use by field crews and project teams

Support Operations with constructability reviews, grading concepts, haul routes, and access planning

Assist with roadway corridor modeling including alignments, profiles, templates, and tie‑ins to existing ground

Review plans and models for inconsistencies such as topo errors, drainage conflicts, and constructability issues

Support estimating and project teams with earthwork quantities and model‑based takeoffs

Assist with proposal graphics, 3D visuals, and conceptual exhibits

Maintain organized files, revisions, and model documentation

Collaborate with project managers, superintendents, survey crews, and operators to ensure models are field‑ready

Learn and apply Fisher's modeling workflows, standards, and file organization practices

Requirements

Experience with heavy civil construction, civil drafting, survey, grading, 3D modeling, or construction technology

Ability to read and interpret civil plans, grading plans, roadway plans, profiles, and specifications

Basic understanding of earthwork, slopes, drainage, and construction tolerances

Experience working with CAD files, PDFs, survey data, and topographic surfaces

Strong computer skills with willingness to learn multiple modeling platforms

High attention to detail and accountability for accuracy

Strong communication skills with both office and field personnel

Ability to manage multiple projects and deadlines

Willingness to travel and work extended hours as needed

Experience with Trimble Business Center and Trimble machine‑control systems

Experience with Autodesk Civil 3D and/or AGTEK

Experience building machine control models for heavy civil equipment

Experience with roadway corridor modeling, site grading, and mass earthwork

Experience with drone data, LiDAR, point clouds, and as‑built comparisons

Familiarity with survey control, coordinate systems, and GPS workflows

Experience supporting field operations, estimating, or project management teams
