From Slide Rules to Finite Element Software. What Five Decades in Grain Engineering Actually Look Like.

“I started in the grain business when silos were designed on paper. With slide rules.”

That is how Luca Celeghini, Founder of CESCO EPC, begins when you ask him about fifty years in the grain industry.

He is not being nostalgic. He is making a point.

“In 1975, a structural calculation that today takes two hours would take a month. You would sit with tables, pencils, and reference manuals. Every beam, every weld, every load case done by hand. The margin for error was the same as today. The time was not.”

Today, CESCO’s engineering team works with 3D CAD and finite element software, automated manufacturing equipment, and structural design workflows that compress weeks of work into hours. Not because the engineering is less rigorous, but because the tools have finally caught up with the discipline.

“We do not use these tools to cut corners. We use them to check more, iterate faster, and deliver plants that are more precisely engineered than anything I could have drawn in 1975. The ambition is exactly the same. The speed is entirely different.”

It is a distinction that matters in an industry where projects are technically complex, timelines are tight, and client expectations are high. For CESCO, the integration of digital engineering and automated manufacturing into EPC delivery is not a technology story. It is an operational one.

“The client does not care how long a calculation took. They care whether the plant works on day one and ten years later. That has not changed in fifty years.”

Fifty years of experience. In-house structural engineering. Automated manufacturing.
