BIM Conversion Services | 2D to BIM, CAD to BIM & As-Built Modelling

BIM Conversion

BIM conversion is essential for transforming legacy 2D drawings and traditional documentation into intelligent, data-rich BIM models. At Triarch Civil Design & Engineering Services, we supportl in converting CAD files, PDFs, point clouds, and as-built drawings into precise and fully coordinated BIM models that strengthen project visualization, collaboration, and overall efficiency.

We strive to leverage industry-leading BIM platforms to reconstruct drawings with accuracy, defined geometry, and structured data tailored to architectural, structural, and MEP systems. The resulting models are organized, highly detailed, and optimized to support design development, clash detection, quantity take-off, and seamless facility management.

What Our BIM Conversion Services Include


  • 2D CAD to BIM Conversion: Rebuilding floor plans, elevations, sections, and layouts into precise 3D BIM models.
  • PDF & Image to BIM Conversion: Transforming static documents into structured, editable architectural, structural, and MEP BIM models.
  • Point Cloud to BIM (Scan to BIM): Creating highly accurate as-built models using laser scan data for renovation, retrofitting, or facility management.
  • As-Built BIM Modelling: Converting existing building documentation into detailed BIM models that reflect current site conditions.
  • Architectural, Structural & MEP BIM: Discipline-specific modelling with accurate geometry, standards, and coordination.
  • Clash-Ready BIM Models: Models prepared for clash detection, coordination, and multidisciplinary review.
  • Standardized BIM Outputs: Deliverables aligned with LOD standards (LOD 100–500), naming conventions, and client BIM protocols.
  • Quantity Take-Off–Enabled Models: BIM models structured for accurate material quantities and cost estimation workflows.
