About The Project
The Commercial Office Facility project in the USA required the development of a detailed as-built Electrical BIM model to ensure the accuracy of the electrical infrastructure and its alignment with the original design. Commissioned by a US-based surveying company, the project covered 277K square feet (25.7K square meters), focusing on providing essential documentation for facility management and system optimization. This project aimed to accurately capture the electrical network and ensure it was fully represented within the as-built BIM model. Using point cloud data, our team modeled key electrical components, including cable trays, electrical closets, and all associated electrical elements. The deliverables for this project consisted of an LOD 350 Electrical BIM model, 3D DWG files, and an accuracy report, providing the client with a comprehensive overview of the electrical infrastructure for future upgrades and maintenance.
Our work was carried out in two phases:
1. Modeling the As-Built Conditions
Our team developed a complete LOD 350 Electrical Systems BIM model reflecting the as-built conditions of the building’s electrical infrastructure. This phase ensured all cable trays, electrical closets, and key elements were accurately documented.
2. Electrical System Comparison – As-Built vs. Design
Upon completing the as-built model, our teams performed a detailed comparison with the original design plans to identify and classify discrepancies.
Each electrical element was categorized according to the described worksets in the legend. This classification process provided the client with insights into deviations, enabling early identification and correction of discrepancies. The as-built Electrical Systems BIM model supports efficient facility management and ensures long-term operational reliability.
Project Challenges & Deliverables
The electrical system modeling phase presented several challenges, requiring our engineering and modeling teams to ensure accuracy and seamless system continuity. One of the primary difficulties involved cable trays installed at three different height layers, complicating their identification and modeling. To address this, our team thoroughly analyzed the LIDAR scans and design data, accurately mapping each tray and ensuring full integration within the system.
In addition to this, the project required the modeling of thousands of electrical elements, necessitating meticulous categorization and attention to detail. Our engineers systematically processed the data to ensure every component was correctly identified and included in the final model. Reflective scans caused by metal systems above the ceiling further distorted the LIDAR data, posing another challenge. Our team applied advanced filtering techniques to refine the scans, producing a clean and coherent dataset that allowed for precise modeling of the electrical infrastructure.
Limited access to certain areas resulted in non-continuous systems and inconsistencies throughout the model. To resolve this, our teams carefully analyzed the layout, filled in the gaps, and ensured the delivery of a continuous and fully operational model. By addressing each of these challenges, our teams successfully delivered an accurate and reliable electrical systems BIM model that supports long-term facility management, efficient maintenance, and system optimization.
