                ##### Exploration:

                This project aims to classify construction site conditions into **safe** or **unsafe** categories using deep learning.

                The model is trained using a MobileNetV2 backbone and achieves high performance in real-world safety image classification.

                The tool supports maintenance planning, reduces on-site risks, and improves safety compliance.
