ROI Calculation Logic

Assuming an average repair cycle of 10 years for a licensee's station platforms, with an annual repair cost of ~$65K (AI est.) per location. Implementing this technology could extend the repair cycle to 30 years, reducing annual costs to ~$20K (AI est.), resulting in an annual saving of ~$45K (AI est.) per location. For approximately 2,000 aging station platforms needing reinforcement, the potential saving could be ~2,000 locations × ($65K - $20K) = ~$850K/year (AI est.). Including construction cost reductions, the total potential cost saving is estimated at ~$1.0M/year (AI est.).

Speed to Market
5× faster than in-house development
