Cost Estimation Skill

This skill provides a systematic framework for estimating the capital costs of urban design projects at the masterplan and district scales. It draws on international construction cost benchmarks (Turner & Townsend, Rider Levett Bucknall, AECOM, Arcadis), infrastructure costing guides (CIRIA, ASCE), and development appraisal methodology (RICS Red Book, ULI).

All costs are provided in USD (2025 baseline) with regional adjustment factors. The goal is to enable early-stage cost estimation accurate to +/- 25-30% (AACE Class 4 estimate) sufficient for masterplan feasibility and design option comparison.
