Challenge

The core challenge of the project was to parse, scan, and interpret data from profile documents, PDF files, and other formats, applying object detection techniques for CAD/BIM tools. The information was often scattered and unstructured across these documents, complicating data interpretation. Additionally, processing the files took too long, which further hindered efficiency.

Solution we Delivered

To provide comprehensive and accurate information about construction projects, Building Information Model (BIM) data is used by design engineers, contractors, and manufacturers. Our task was to develop an object detection system for the BIM tool and present the data outcomes in a user-friendly front-end interface.

Object Detection Algorithm

We selected YOLO for object detection within the files. The model was customized to extract relevant data and convert it into a structured, searchable format.

AI Component from Scratch

Since not all elements in the files were marked as text inputs by users, our developers created an AI component to enhance parsing through advanced labeling techniques, ensuring all relevant elements were included.

Front-end Display

After parsing all required components and optimizing file processing speed, we developed a front-end interface designed to present the extracted data in a user-friendly manner.
