Responsibilities

Prepare existing-ground, proposed-grade, and finished-surface models from civil plans, survey files, specifications, and design data.
Create and organize linework, breaklines, alignments, profiles, corridors, surfaces, and related CAD data for field use.
Develop machine-control and construction-layout files for grading, utilities, drainage, roadways, curb, stone base, and paving operations.
Perform quality-control checks for elevations, slopes, offsets, boundaries, layer standards, units, coordinate systems, and file completeness.
Identify plan conflicts, missing information, and model discrepancies, and coordinate questions with project managers, estimators, survey personnel, engineers, and field teams.
Incorporate approved revisions, addenda, field changes, and updated survey information into current models and drawings.
Maintain clear file structures, version control, naming conventions, data backups, and model documentation.
Export and convert files into formats required by survey, GPS, machine-control, estimating, and construction systems.
Support quantity takeoffs, earthwork analysis, constructability reviews, and troubleshooting of model-related field issues.
Follow company standards for accuracy, safety, confidentiality, and timely delivery.
