Design has never involved so much responsibility as it does today.
It’s not just a question of visual appeal.
Nor is it just a question of utility, durability, or sustainability.

Human Value

Passion for design, passion for people: we work every day to create an organization which is human and friendly in spite of being large and efficient.


We deeply care about our work and seek to produce better outcomes for our clients, the public and our planet. Our activities are certified for compliance with the top ISO quality and environmental management standards.


We believe that our projects should aim at the health and well-being of our communities. We work closely with our clients to develop bespoke design solutions that are optimized for their operations and the planet.


We strongly advocate employee ownership as a tool for organic growth and independence. We constantly monitor the transparency and integrity of our operators through internal enforcement of legislation against corruption and criminal activities.

Employee Ownership

The aim is to strengthen the application of employee ownership principles, through ownership of company shares by the people who actively contribute to the productive life of our company. Today we are the only Italian member of the Employee Ownership Association.

Integrated Engineering

We operate in all fields of Engineering and Architecture from feasibility studies to construction and testing, being engaged in each specialist field, none excluded. All relevant design decisions must integrate into a whole by a well-organized team empowered to fix priorities.


We look with continuity at the latest learning, updating, and training opportunities. The outcome is a team of result-oriented experts, continuously investing in their skills aiming at maximizing the quality of the rendered services, through technology and imagination.

Global Player

We have been operating around the world for more than 25 years and we have completed more than 2,500 engineering projects in over 30 countries.
