SOFTWARE WE USED
Business Needs
The OGTR (Old Georgetown Road) and Edgemoor Lane Pedestrian bridges play a vital role in the county’s transportation infrastructure. Accurate as-built documentation of the existing pedestrian bridges was required by the county to serve as a reliable baseline for future renovations and maintenance. With Tejjy’s extensive expertise in 3D lidar scanning, Scan to BIM services, and infrastructure BIM modeling, we were selected as the ideal partner for this project.
Key Objectives:
- Deliver accurate reality capture of the existing site conditions with extreme precision.
- Provide a construction-ready LOD 500 model to minimize risks and ensure precise alignment for design and construction teams.
- Ensure seamless coordination with existing infrastructure, MEPF systems, and traffic management while maintaining operational efficiency.
Challenges
The project posed several challenges that required innovative solutions:
- Capturing precise 3D data was difficult due to the bridge’s design and surroundings, requiring advanced scanning techniques.
- Public access and ongoing infrastructure operations required careful planning to minimize disruptions.
- The project required uploading raw and processed scan files to MCDOT’s 3D Scan Storage, ensuring compliance with industry-standard formats for long-term usability.

Our Solutions & Approach
Our team adopted a comprehensive approach to overcome challenges and deliver a successful outcome.
- We deployed Leica RTC360 and BLK360 laser scanners to capture highly accurate as-built data, ensuring a NAD83 georeferenced 3D scan for precise alignment with existing infrastructure.
- Team Tejjy Inc. delivered a Level of Development (LOD) 500 Scan to BIM model for accurate as-built documentation of road infrastructure, supporting future renovations, maintenance, and infrastructure upgrades.
- We put into action our digitized AEC solutions by utilizing Autodesk Revit and Navisworks to integrate MEPF coordination, ensuring clash detection and inter-disciplinary interoperability.
- Submitted both raw and processed 3D scan files to MCDOT 3D Scan Storage. Our scan-to-bim experts ensured data compliance with industry-standard formats (e.g., .e57, .rvt, .ifc).
Business Impact
- Scan to BIM significantly reduced the time required for traditional surveying and minimized costly rework due to design errors.
- Compliance with MCDOT’s data storage protocols ensured long-term accessibility of scan data, supporting future public infrastructure initiatives.
