Scan-to-BIM and As-Built Modeling for Multi-Level Parking Garage Facility, Maryland

3D Scan-to-BIM and as-built BIM modeling are being delivered for a multi-level parking garage facility improvement initiative in Maryland. The project focuses on capturing accurate existing conditions and developing coordinated BIM models to support modernization efforts, including electrical infrastructure planning for EV-ready upgrades.

• The scope includes creating discipline-specific as-built models for architectural, structural, and MEP systems, ensuring a unified baseline for constructability and multi-trade coordination.
• Dense service routing zones, tight clearance conditions, and layered structural geometry required high-precision reality capture and detailed model validation.
• The workflow also demanded reliable point cloud registration and iterative coordination to identify spatial conflicts early, especially in areas where new electrical pathways and equipment integration were being evaluated.
• Led by Tejjy Inc.’s reality capture and BIM delivery team, the use of RTC 360 LiDAR, Cyclone Registration 360, Autodesk Revit, and Navisworks enabled accurate documentation and proactive issue resolution.
• Resulting in an asset-enabled as-built BIM model that strengthens facility management readiness and supports future electrification needs such as EV charging integration.

Delivering accurate Scan-to-BIM and as-built BIM models for a multi-level parking garage in Maryland required a reality-driven digital execution strategy powered by LiDAR scanning, Autodesk Revit, and Navisworks. Tejjy structured the workflow to ensure each discipline operated inside a coordinated BIM environment that supports upgrades and long-term operations.

Key strategies involved:

• Capturing existing conditions with high-precision RTC 360 LiDAR across all levels and critical service zones.
• Registering and optimizing point cloud data in Cyclone Registration 360 for BIM-ready accuracy.
• Developing coordinated architectural, structural, and MEP as-built models in Autodesk Revit.
• Federating trade models in Navisworks for iterative clash detection and constructability validation.
• Embedding asset data for electrical components, fixtures, and equipment to enable maintenance workflows and infrastructure planning, including EV-ready systems.

This integrated scan-to-BIM approach reduced uncertainty early, improved coordination, and delivered a facility-management-ready digital twin supporting modernization and electrification initiatives.

• LiDAR-based reality capture and point cloud documentation for existing parking garage conditions.
• Registered and optimized point cloud dataset aligned for Scan-to-BIM workflows.
• As-built architectural, structural, and MEP BIM models developed in Autodesk Revit.
• Federated Navisworks coordination models (NWF/NWD) for multi-trade integration.
• Iterative clash detection reports and issue logs supporting constructability validation.
• Embedded asset information for electrical equipment and future-ready infrastructure planning.
• Facility-management-ready digital twin supporting upgrades such as EV charging integration.
