Hoarding Wind
Stress Simulator.

I built a browser-based 3D simulator for my father’s outdoor advertising business in Mumbai. It helps him explore a proposed hoarding’s response to wind before committing to steel and concrete.

The product turns a technical model into a practical flow: choose a wind scenario, soil type, and structure, then review a preliminary verdict and suggested changes.

A preliminary design exploration tool, not a certified engineering product. Every proposed structure still needs review and sign-off by a licensed structural engineer.

My dad designs and installs hoardings across Mumbai. Before each monsoon, the same question returns: will this structure hold?

The May 2024 Ghatkopar hoarding collapse made that concern especially immediate. For his business, the practical need was a faster way to question a design before construction.

Mumbai’s coastal exposure, monsoon conditions, and varying ground conditions make the context important. I wanted to help him discuss a proposal with numbers and visible scenarios alongside his experience.

How can I make an early structural check understandable enough that he will actually use it?

I built the simulator for my father’s business and shaped the experience around how he thinks about structures: plain-language choices, a visible model, and a clear result.

The work brings together product design, an engineering model, and Three.js visualization. The interface supports preset scenarios as well as custom inputs for a more detailed discussion with his engineer.

A “safe” model result is not permission to build. The animation illustrates the simulation; it does not validate real-world performance.

Wind loading

Wind-pressure calculations reference IS 875 (Part 3). Their implementation and assumptions require engineering validation.

Soil and foundations

Ten soil categories, from loose fill to hard basalt, and four foundation options: footing, pile group, raft, and drilled pole.

Structure configuration

Single-pole, twin-pole, and four-leg tower arrangements.

LED and print panels

Separate panel choices account for differences in weight.

Design recommendations

Candidate pole and foundation changes based on the selected load scenario.

Regulatory context

BMC size and certification references provide context for review. They do not establish that a proposed design is compliant.

The project demonstrates how I translated a family business’s technical question into an accessible product. I have not included measured usage outcomes or independent model-validation results.

Validate the calculations

Compare model outputs with calculations reviewed by a licensed structural engineer across representative configurations.

Test interpretation

Watch my dad use the tool and check whether he understands what each verdict means, which assumptions affect it, and what needs professional review.

Keep references traceable

Record the standards, policy versions, model assumptions, and review dates behind the calculations and regulatory guidance.

These are proposed validation steps, not completed tests.

• Three.js
• Engineering model
• Product design
• IS 875 reference
• IS 800 reference

BMC’s 2025 advertisement policy includes structural design, audit, and certification requirements, and references IS 875 and IS 800. Those requirements provide context; they do not certify this simulator.
