About CN3

CN3 is a technology and engineering consultancy specializing in automation, digital engineering, and constructability for complex construction projects. Since 2013, we have helped contractors and owners replace coordination-heavy processes with model-driven, automated workflows that improve predictability and execution.

Headquartered in Copenhagen and operating across Northern Europe, CN3 has delivered digital solutions on more than 400 building, infrastructure, and industrial projects. Our work spans the full delivery lifecycle — from early design and preconstruction to manufacturing and site execution.

By building projects digitally first and applying automation, Design for Manufacturing, and structured information management, we turn complex construction into controlled, repeatable delivery processes. The result is fewer errors, faster decisions, reduced risk, and more reliable outcomes — from day one.

CN3 helps the construction industry move from manual coordination to industrialized, data-driven delivery.

With digitalization and increased use of technology, we will be leading the way to a leaner, more sustainable construction industry
