A Comprehensive Project Engineering Offering

Organized into three engineering divisions with dedicated human resources—Project Management, Structures, Railway Systems and Metros—NGE Engineering leverages the expertise of NGE’s advanced sectors and dedicated design offices for our eight disciplines.

This approach provides a global vision of projects, enabling strategic decisions on the design and construction of structures by balancing various aspects (construction methods, operations, material choices), particularly favoring environmental considerations.

 

Our areas of expertise

Project Management 

In an ever-evolving environment marked by increasing complexity in infrastructure projects and the need to integrate aspects such as sustainable development, digital technology, and BIM, Project Management ensures technical control, quality of delivered structures, and adherence to commitments.

Our Services:

  • General Studies: Analysis of context and client needs, functions of structures, value and risk/opportunity analysis, data/constraint analysis, project challenges. Feasibility studies, socio-environmental impact studies, road and railway route studies.
  • Technical Studies: Technical design studies from preliminary phases to project phase.

  • Execution Studies: Technical specifications and technical assistance during the construction phase.

  • BIM 

Structural Engineering Expertise 

Structural studies are the cornerstone of the success of your civil engineering and structural projects. We support you to ensure the safety, reliability, and constructability of structures, while adapting to site and future construction realities.

Our Services:

  • Design and Execution: Studies of all types of new or existing structures to be reinforced. Advanced modeling (BIM).

  • Optimization: Sizing according to current standards (Eurocodes, AASHTO), seeking structural solutions that are both efficient and economical.

  • Methods and planning: Study of construction methods and provisional phases to ensure safe site completion, study of work schedules.

Specialist in Railway and Metro Systems 

Launched in 2025, our Railway and Metro Systems Engineering team supports you at every stage to ensure the successful delivery of your projects within optimal timeframes.

As a true driver of innovation, risk management, and reliability, NGE Engineering leverages its multidisciplinary expertise to design comprehensive railway and metro solutions—from track to signaling—covering everything from design through commissioning and maintenance.

BIM, a unique interactive model

 

Create, Visualize, and Optimize Your Project

From the blank sheet to the maintenance of infrastructure, NGE teams collaborate on a digital model, Building Information Modeling (BIM).

A true predictive tool, BIM allows for anticipating cost, schedule, and resource management from the early design phases. Used throughout the project, it ensures complete traceability of the history, optimizing the entire lifecycle of a structure and ensuring its maintenance after project completion.

Innovative and Responsible

Committed to sustainable infrastructure, NGE INGENIERIE designs structures that integrate social, environmental and regional issues right from the design stage, while actively contributing to the transition to low-carbon infrastructures.

What we do

We have established a partnership with Green Praxis, a start-up specializing in environmental satellite data analysis. This enables us to determine the ideal position of large fauna passages on linear infrastructures, based on the seasonal mobility of species (reproduction) and daily mobility (feeding).

Designing is a unique challenge

« Engineering is about designing projects and then supporting their implementation. It requires project management, technical expertise, technological processes and methods to determine how to design and then build, in what order, how long, with what and with whom. But it doesn’t stop there: it also requires research and development, in particular digital innovation around BIM »
