Learning – Continuous Improvement
What’s Lean about Design-Build?
Designers and builders working side by side
Designing once to how we want to build it
Coordination that eliminates waste (like RFI’s)
3-D Imagery for quick decision making
Utilizing BIM models for cost estimating
Designing to a cost (TVD)
