CDC
Engineering services
Specializing in energy transmission lines, CDC was born from the former SAE of Lecco, whose legacy it continues to uphold. Experience, expertise, and a Zero Error philosophy are the defining traits of the company, which over the years has participated in projects worldwide and has contributed to innovative works in its sector.
CDC technicians support clients at every stage of the process, from the initial design to inspection and testing at production sites.

What we do
The company works alongside the client throughout the entire project, whether it involves power lines, industrial structures, or other works requiring the expertise of our technicians. Precision and top-quality results have always been our trademarks.
Case history
We have participated in several projects over the years that have garnered significant attention due to their complexity, innovation, or their beauty and the fascination they evoke in both the public and technical professionals. Here are a few examples.
