Position Overview

The Senior Precast BIM Modeler leads the development of high-precision, data-rich 3D parametric models for precast and prestressed concrete elements. Operating within a precast engineering and manufacturing workflow, this role acts as the technical nexus between structural engineering design, factory automated production, and site installation. The Senior BIM Modeler transforms structural concepts into LOD 400/500 fabrication models—generating accurate element shop drawings, bar bending schedules (BBS), hardware embed layouts, and CNC/CAM data for automated mold setup.

Key Responsibilities

• High-LOD Modeling & Fabrication Documentation

  • Develop complex, fully parametric 3D precast models (LOD 350 to LOD 500) for structural and architectural elements (beams, columns, hollow-core slabs, double tees, insulated sandwich wall panels, and staircases).

  • Extract detailed precast shop drawings, piece tickets, element layouts, bar bending schedules (BBS), and strand/hardware embed schedules directly from the model.

  • Populate parametric families/components with metadata required for factory production tracking and material procurement.

• BIM Coordination & Clash Detection

  • Run multidisciplinary clash detection (Architecture, Structural, MEP, and Precast connections) using Navisworks or Solibri.

  • Resolve spatial conflicts regarding MEP cast-in sleeves, lifting anchors, connection plates, and post-tensioning ducts before releasing drawings to production.

  • Ensure full alignment with project BIM Execution Plans (BEP), ISO 19650 standards, and client modeling requirements.

• CAM / Factory Automation Integration

  • Generate and export automated machine data formats (e.g., BVBS, Unitechnik, DXF) from 3D models to drive CNC mesh welders, shuttering robots, and automated plotters.

  • Coordinate with plant managers to ensure model breakdown aligns with factory bed capacities, mold dimensions, and crane lifting limits.

• Team Leadership & Quality Control

  • Perform strict quality control (QC) checks on models and shop drawings produced by junior BIM modelers and detailers prior to engineering sign-off.

  • Mentor junior team members on advanced modeling techniques, dynamic family creation, and efficient precast detailing workflows.
