Reliable Deliveries, Clear Crane Windows, and Safer Evacuations

Urban sites change daily. Traditional logistics plans are drawn in 2D, stored in markups and emails, and quickly drift from reality. They rarely account for vertical clearances or temporary works, so delivery routes and crane picks are revised late. Gate congestion, crane idle time, and avoidable lane closures accumulate. Safety planning often sits beside logistics, not inside the same week‑to‑week decisions, so evacuation routes and muster discipline are uneven. Subcontractors work from different snapshots, which fuels miscommunication and rework. Bird needed a single way for teams to see the real site, the sequence, temporary works, pedestrian protection, and hazards together, then make decisions that carry into daily work plans. The method had to be simple enough for superintendents and trade foremen to use in the field, not only by a central digital group. We targeted three pain points: routes and delivery windows that hold under changing conditions, crane picks that clear in 3D before the weekend, and evacuation routes that are briefed, drilled, and adjusted as the site evolves. The legacy approach could not deliver that consistency. We replaced it with a live, model‑driven workflow that ties logistics and safety to stage gates, so decisions are made in the same environment everyone sees and uses on site.

We implemented a five‑gate logistics workflow built around a live site model that field teams and subcontractors actually use. - Gate 1, Initial site mapping: drone photogrammetry and, where needed, LiDAR fused with design models to produce an accurate baseline for haul roads, laydown, grades, and overhead constraints. - Gate 2, Model‑based pre‑planning: brief weekly reviews with trade partners inside the model, setting routes, delivery windows, hoist interactions, crane reach, pedestrian paths, and exclusion zones. - Gate 3, Coordinated execution: deliveries, crane picks, and high‑risk activities are validated in the model before the work window. Evacuation routes and muster points are reviewed with crews. - Gate 4, Live monitoring: the model is refreshed as stockpiles move, pours complete, or fencing shifts, so plans reflect current conditions. - Gate 5, Feedback and improvement: drill results, incidents, and lessons feed standard views and checklists that lift the next project. Field crews access simple model views on tablets. Subcontractors see the same views, which turns the model into the communication channel. Decisions made in reviews are captured as model states and simple checkpoints tied to the gates, so they appear again when the related work is scheduled.
