From my experience working on mixed use projects at schematic design level, the biggest risk comes from decisions made without structured technical validation. When I was involved in similar situations, engaging Consulting Services early helped me translate conceptual design into buildable solutions by reviewing structural grids, vertical circulation, and mechanical zoning together. I learned that early interdisciplinary coordination exposes scope gaps, unrealistic assemblies, and sequencing conflicts that directly affect cost and schedule. By addressing these technical risks before construction documents, I was able to stabilize budgets, reduce redesign cycles, and move into later phases with far fewer unknowns.
