Ambienta SGR S.p.A. announced that its platform company Officine Maccaferri S.p.A has acquired CPT Group an Italian company specialized in advanced mechanized tunnelling technologies and robotic prefabrication systems for underground infrastructure.

Founded over 30 years ago and based in Nova Milanese (Italy), CPT serves major global contractors in the tunnelling and infrastructure sectors. Its offering combines robotic prefabrication plants (Robofactory), productivity-monitoring software for tunnel boring machines (TBM) and eco-designed spacers. As a pioneer in applying Industry 4.0 principles to the prefabrication processes of segments for Tunnel Boring Machines (TBM), CPT has helped advance automation in underground construction sites. Its technologies have already been successfully employed by Maccaferri for the installation of its semi-automated steel ribs. With operations across Europe, Southeast Asia, and Australia, CPT is recognized for enabling more resource-efficient, safer and faster construction of tunnel linings in geologically complex environments.
With this acquisition, Officine Maccaferri becomes one of the major industrial players globally able to offer a fully integrated tunnelling platform, covering both traditional systems (steel ribs, fibres, gaskets) and mechanised solutions (Robofactory, TBMs, digital technologies). The combined Group will serve a growing €1 billion addressable market, further consolidating Maccaferri’s transformation into a technology-enabled leader in sustainable infrastructure.
Andrea Venturini, Private Equity Partner at Ambienta, commented: “This acquisition reaffirms Officine Maccaferri’s ambition to become the global platform for climate change adaptation engineering solutions. With CPT, the Group strengthens its ability to develop new business lines, integrate cutting-edge technologies, and act as a consolidator in highly specialised industrial niches. It is a further step in building a diversified and resilient leader across all core infrastructure markets.”
Stefano Susani, CEO at Officine Maccaferri, added: “The integration of CPT gives us a unique opportunity to scale our tunnelling division into a global leader for mechanised and traditional solutions, enhanced by advanced industrial robotic automation. We see significant potential to create long-term value by offering an integrated platform to key accounts worldwide, supporting the most complex and strategic underground infrastructure projects through innovation, reliability, and sustainability.”
Klaus Pini, co-founder of CPT, commented: “Joining Officine Maccaferri is a natural evolution for CPT. We share the same industrial values, long-term vision, and commitment to engineering excellence. This partnership will allow us to accelerate the development of our technologies and bring even greater value to our clients and the tunnelling industry worldwide.”
