• Attend model coordination meetings and assist in resolving layout conflicts with other trades.
• Coordinate clash detection and resolution processes in multidisciplinary coordination meetings, solving spatial conflicts with structural and other trades.
• Update models to show design changes and answers to RFIs, and distribute the revised files to the team.
• Bridge the gap between design and execution by collaborating directly with project managers, shop foremen, and field crews to translate models into actionable installation data and spool drawings.
• Perform constructability reviews of contract documents, identifying design discrepancies, RFIs, and material inconsistencies to prevent field re-work.
• Update as-built models throughout construction to reflect field changes and keep an accurate revision log.
• Assist the project team with basic construction coordination, scheduling, and gathering final virtual construction close-out documents.
• Perform other general detailing responsibilities as assigned.

MATHEMATICAL SKILLS
Ability to apply advanced geometric and algebraic concepts to calculate precise piping slopes, centerlines, rolling offsets, and spatial clearances. Proven ability to verify dimensional accuracy, calculate material take-offs, and interpret level, elevation, and coordinate data from 3D models and field measurements.

REASONING ABILITY
Ability to apply logical thinking and spatial reasoning to carry out instructions provided in written, oral, or diagram form. Proven ability to identify and resolve multi-variable spatial conflicts and design discrepancies, such as reconciling conflicting layout data between contract drawings, architectural constraints, and structural limitations.
