Sea Bridge Collapse Simulation Slides -- 3

I am compiling an investigative report on a recent sea-crossing bridge failure. I already hold a set of clear “before” and “after” photographs; what I now need is a sequence of static, fully-annotated slides that visually reconstruct the event from start to finish.

Scope of the simulation
• Re-create the bridge deck, supporting columns and the maintenance platform beneath.
• Illustrate live traffic flow at the moment of failure, showing the single car that ultimately plunged into the water.
• Depict the progressive loss of column capacity, followed by the deck collapse and the subsequent rescue operations.
Your visuals should move through the pre-incident condition, the actual collapse, and the immediate aftermath so the chain of events is unmistakable.

Required annotations
• Technical details and key measurements (column dimensions, estimated loads, visible corrosion length, etc.).
• A clear, step-by-step narrative of what happened, synchronised with timestamps where possible.
• Explicit call-outs of the maintenance shortcomings that triggered the failure.

Preferred format
Static slides with layered annotations are mandatory; feel free to build assets in CAD, SketchUp, or any 3D package, but the final hand-off must open cleanly in PowerPoint (or Google Slides) so my team can edit text if needed. High-resolution JPEG or PNG inserts for each stage are welcome as supporting files.

Acceptance criteria
1. 12–15 slides that lead the viewer logically from “intact bridge” to “post-collapse rescue”.
2. Each slide pairs a clear graphic with concise, technically accurate notes.
3. All critical dimensions and failure points are labelled.
4. The deck-car interaction and column behaviour are visible without animation.

Deliver everything via a single shareable folder, organised by slide order and accompanied by any editable source files. I’m on a tight timeline, so please include an outline of your approach and a realistic turnaround when you reply.
