Building a Digital Twin-Ready 3D BIM Model for a Telecom Tower

About the Customer

A global telecommunications infrastructure operator focused on modernizing its tower assets to enable digital twin adoption, improve asset visibility, and support future data-driven operations.

Situation

The client had 2D CAD drawings and site photographs of an existing telecom tower and required a precise, lightweight, geometry-only BIM model to support future asset tagging, analytics, and digital twin integration.

Task

• Converting 2D CAD data into a 3D geometry-only BIM model
• Accurately modelling the tower structure and telecom equipment
• Ensuring compliance with client BIM and IFC standards
• Delivering a model optimized for future data enrichment

Action / Approach

• Analysed 2D CAD drawings to extract structural and equipment dimensions
• Validated equipment type, orientation, and layout using site images
• Modelled tower components – legs, bracings, platforms, ladders, and safety elements
• Created simplified, geometry-only Revit families for antennas, RRUs, microwave dishes, cable trays, and power equipment
• Ensured correct placement, elevation, and alignment
• Performed visual QA/QC and IFC readiness checks

Result

• Establish a solid 3D geometry foundation for digital twin initiatives
• Enable future asset tagging and parameter population without rework
• Reduce modelling effort and downstream project risk
• Maintain a lightweight BIM model suitable for enterprise workflows

Tools / Software

• Autodesk Revit
• Autodesk AutoCAD
