ROI Calculation Logic

This technology enables one non-specialist to complete ground survey and analysis tasks that traditionally required multiple days and skilled technicians. Assuming 3 skilled technicians handle 100 projects annually, with each project costing ~$3,350 (AI est.), the total annual cost is ~$1.0M (AI est.). By improving process efficiency by 20%, an estimated annual cost reduction of ~$200K (AI est.) is achievable. Additionally, automated data quality management reduces re-measurement efforts, contributing an estimated ~$130K (AI est.) in annual savings.

Speed to Market
