Most concrete looks the way it does for one simple reason.

We keep designing around the forms we know how to build.

In this episode, Seth sits down with Darren Baldwin, President of PIKUS, to break down the real difference between analog formwork and digital formwork—and why that distinction quietly limits what architects, engineers, and contractors think is even possible with concrete.

This is not a hype-filled “3D printing is the future” conversation. It’s a practical discussion about where digital formwork actually works, where it absolutely doesn’t, and why architectural concrete—not structure—is where this technology earns its keep.

WHAT YOU’LL LEARN
• What “analog vs. digital formwork” really means in construction terms
• When digital formwork beats precast on cost, logistics, and constructability
• How curves, grade changes, and non-repeatable geometry break traditional forms
• Why lack of data (and testing) still blocks structural adoption
• Why architects keep designing square stuff when they don’t have to

INTELLIGENT CONCRETE
Concrete not behaving the way it should?

At Intelligent Concrete, Dr. Jon Belkowitz and his team combine lab-level testing with real-world field experience to get to the root of performance issues, not just the symptoms.
