The ‘System Engineering’ method

Innovative approach and know-how: NET Engineering is the leading company for the system design of infrastructures.

Here at NET we believe that in every project – big or small – one must go beyond the single infrastructure, the immediate needs. We feel that in order to design and plan responsibly, every project must be seen as a system engineering project.

It must not only be technically feasible but has to be based on the quantitative assessment of its impacts against objectives and constraints internal to the transportation system as well as at the environmental, social, economic and territorial levels.

A system-engineering project considers alternative solutions by identifying the project’s objectives and constraints, satisfying the project’s requirements, defining and describing the elements of the system, simulating impacts, evaluating effectiveness, analysing economic and financial suitability, assessing social acceptance.

The detailed design of the project will only start once all of these considerations have been carefully dealt with.

The ‘NET method’ for Mobility

System engineering is an interdisciplinary field of engineering, that focuses on the development and organization of complex artificial systems.

Its mission is creating and executing an interdisciplinary process to support the evaluation of the main potential effects of the projects, to test their technical and economical suitability and to sustain decision-makers.

NET Engineering is proud to have long mastered the method of system engineering for Mobility, as our completed projects (view) so ably illustrate.

The ‘technical’ elements in the system, governed by the laws of physics, are traditionally studied by engineers, but transportation analysis requires a different kind of approach, drawing on concepts from social and economic sciences.

The number of travellers or the quantity of goods using transportation systems, their performances and their impacts are strictly connected to travel demand and users’ behaviour. Thus, the analysis of travel demand plays a key role in understanding and designing transportation systems. Transportation projects may have a bearing on many, often conflicting, interests: the economy, the location and intensity of the activities in a given area, the environment, the quality of life and social cohesion.

Due to the large number of variables and the complexity of their interactions, modelling the effects of transportation projects requires powerful mathematical tools for satisfactory design. Such models are fundamental for evaluating or designing actions affecting the physical elements or organisational components of transportation systems.

According to NET’s method, any infrastructure must be put in the socio-economic, territorial, urban and environmental context that hosts it, enabling the designers to assess the impacts generated and received by the infrastructure itself. So, it is possible to identify the most reasonable and shared solution, that will surely represent the ‘optimal’ compromise that takes into account all factors that come into play and offers answers to the real needs expressed by the territory which will host the infrastructure.

Here at NET we believe that this is the only way to approach each project we are entrusted with, irrespective of size or complexity. This is why, over the years, we have invariably satisfied our clients and stakeholders with our final proposals. It is our fervent hope and aim to continue to do so.

Program Management

The design of large infrastructure projects requires appropriate tools and skills to address the high complexity of its implementation.

Complex infrastructures (large urban development projects, road and rail networks, etc.) are not comparable to a single large project: they are described as a set of different projects that are, at the same time, related and aimed at reaching a single goal.

In this context, it is essential to adopt more sophisticated planning and monitoring tools, advanced computer skills and high-level management skills aimed at prioritising resources across projects. The experience and expertise of the team responsible for the management of a project become crucial and essential for a client.

In addition, our consolidated Project Management competences can guarantee the execution of one or more projects while adhering to safety, schedule, costs and responsibility targets.


All buildings should be so carried out that account is taken of strength, utility and grace. Account will be taken of strenght (firmitas) when the foundations are carried down to the solid ground, and when from each material there is a choice of supplies without parsimony; of utility (utilitas), when the sites are arranged without mistake and impediment to their use, and a fit and convenient disposition for the aspect of each kind; of grace (venustas), when the appearance of the work shall be pleasing and elegant, and the scale of the constituent parts is justly calculated for symmetry...

Marco Vitruvio Pollione – “De Architectura” (15 A.C.)


NET puts its faith in the Vitruvian concepts of ‘firmitas, utilitas, venustas’ by adopting an innovative – lean, smart & green – design approach and always pursuing the sharing of choices through consensus building.


We apply the principles of lean thinking and lean production to the engineering field. We always optimize the design solutions through the best choice of layout, materials, construction techniques: only what you need, and only when needed. We perform cost analysis of the works throughout their life cycle, with identification of modular and flexible design solutions aimed to the reduction of realization costs.


We integrate the technological innovations into the design of infrastructure. We make a systematic use of new technologies in particular those of computing, telecommunications and the energy sector; we deal with infrastructure/user interaction, through the use of Intelligent Transportation Systems.


We pay attention to the environmental sustainability of infrastructure projects, through the smooth integration of the works into the landscape and the territory. We use the best technologies and materials to ensure energy efficiency, and minimize impacts; we adopt innovative techniques for environmental monitoring, during construction and in operation.


We are always close to the needs of Clients and Communities:
this is the main motivation of our professional behavior and our steady vocation for excellence.

We adhere to the old Vitruvian principles, adapting them to the changing and complex manifestations of contemporaneity.
