About The Project
The bank building project in Israel required the development of a precise as-built HVAC BIM model to ensure the accuracy of the existing infrastructure and its alignment with the original design. Commissioned by an Israel-based surveying company, the project covered 1 million square feet (93K square meters) and provided essential documentation for future renovations and facility management. This project ensured the bank’s HVAC infrastructure was thoroughly documented and compliant with operational standards.
Using point cloud data derived from LIDAR scans, our team modeled critical components, including HVAC ducts, ceiling vents, supply/return classifications, and all electrical HVAC elements. Deliverables for this project included an LOD 350 as-built HVAC BIM model, 3D DWG files, and an accuracy report, equipping the client with comprehensive tools for managing and maintaining the HVAC system.
The project was executed in two primary phases:
1. Modeling the as-built conditions
- our team developed a detailed LOD 350 HVAC BIM model that accurately captured the as-built conditions of the building’s HVAC systems. This phase ensured that all ducts, vents, and electrical HVAC components were fully represented.
2. HVAC System Comparison – As-Built vs. Design
- after completing the as-built model, our teams conducted a comprehensive comparison against the original design plans to identify discrepancies.
Each HVAC element was categorized by accuracy according to the described worksets in the legend. This classification process provided the client with clear insights into discrepancies, allowing for prompt adjustments and ensuring the HVAC system’s accuracy and functionality. The as-built HVAC BIM model supports long-term facility management and operational efficiency.
Project Challenges & Deliverables
The HVAC modeling phase for the main bank building presented several challenges that required the expertise of our engineering and modeling teams to ensure system accuracy and completeness. One major challenge involved vertical HVAC ducts hidden within the walls across most areas of the building, limiting visibility in the scans. Drawing on visible data and extensive experience, our teams reconstructed the vertical trays to establish a continuous supply and return system.
Additionally, the above-drop-ceiling scans were highly reflective due to existing metal infrastructure, which distorted the LIDAR data. Our teams filtered and refined the scans, creating a coherent dataset that enabled precise modeling. Limited access to certain areas resulted in non-continuous HVAC systems, leading to gaps and inconsistencies. Our engineers analyzed the overall layout, filling in missing sections to deliver a fully connected and operational model. Through innovative problem-solving and expert modeling, we provided an accurate and reliable HVAC BIM model that supports the long-term functionality and maintenance of the bank’s HVAC systems.
