Library renovation activity-on-arrow diagram

This activity-on-arrow diagram shows how a library can coordinate a single-room renovation. A survey and plan approval come first, then shelf ordering, room clearing and light wiring proceed in parallel. The reopening event depends on all three activities, making the required readiness condition clear. The arrows hold the work and durations, while the nodes mark the points where project conditions are met. It is useful for facilities teams that need to explain a compact renovation sequence to library staff, vendors and contractors. Adapt the tasks for permits, flooring, equipment delivery or a staged reopening when the project needs them.
