I'm excited to share our latest case study featuring a high-precision as-built modeling project using 3D laser scanning technology for an office building in Maryland. This project showcases our workflow, tools, and benefits for future restoration planning."
Case Study Overview:
The Precise As-Built Modeling with 3D Laser Scanning For Office Buildings in Maryland focuses on overcoming challenges in creating detailed As-Built models for an office space. It involved using the Leica RTC 360 scanner for high-resolution 3D scanning to capture the facility’s spatial data. The waterfall methodology was employed to ensure precise execution, with focus on model data consistency and future flexibility in refurbishment planning.

Technical Resources:
- Standards for As-Built Drawings:
Refer to AIA (American Institute of Architects) or NCS (National CAD Standard) guidelines for formatting As-Built drawings. These guidelines help in ensuring:- Consistency in symbol usage and drawing formats
- Accurate notations for revisions
- Proper layering for various building systems (e.g., MEP, structural)
Checklists for As-Built Documentation:
- Site Condition Validation:
- Actual site conditions to be verified through 3D laser scanning.
- Scanned data to be cross-checked with existing architectural/engineering plans.
- Data Conversion:
- Ensure scanned data is converted into a usable CAD/BIM model.
- Clash detection and design validation should be performed within the model.
- Model Quality Check:
- Review the integrity of the data at every step, ensuring accuracy and consistency.
- Validate field markups are incorporated properly.
- Documentation of Changes:
- Maintain detailed records of any changes made during the scan-to-BIM process.
Keep detailed notes on any changes that happen during the scan-to-BIM process.
