Optimization of Evacuation Route Design in the Civil Engineering Department Building, Library and Student Organization Building Using Visual Analysis

The safety of building occupants during emergencies, such as fires or earthquakes, depends heavily on effective evacuation route planning. Buildings such as the Civil Engineering Department, Library, and Student Organization Building at Manado State Polytechnic have high spatial complexity, requiring a thorough evaluation of existing evacuation routes. This study sought to improve occupant safety by analyzing the spatial layout of these three buildings. The research employed a descriptive qualitative and surveying approach, utilizing drones, Total Station, and direct measurement to gather high-fidelity spatial data. This data was processed into 2D and 3D models using AutoCAD and Civil 3D, which were then subjected to a detailed visual analysis. This analysis focused on identifying areas of low visual connectivity (sightlines to exits) and low spatial integration (potential bottlenecks) that could impede emergency evacuation. The goal was to identify and recommend optimal, data-driven evacuation routes and signage placements. The results include specific, practical design recommendations that are expected to yield a more effective and efficient evacuation route design, thereby significantly improving occupant safety and contributing a valuable application of visual analysis methods in disaster-resilient building planning.
