ENGINEERING · CONSULTING SERVICES · EXPERTISE
From overhead lines to trains. From substations to intelligent mobility. GICMEI connects engineering, project delivery and operational realities.
01 / ABOUT US
GICMEI brings together a team serving engineering, mobility and energy.
Consulting services and technical assistance are at the heart of our business. We mobilise the right skills to support project owners, engineering firms, contractors and operators in their studies and projects.
Our development combines recruitment, knowledge transfer and the structuring of expert support around our consultants. A shared commitment guides our work: understanding the need, managing interfaces and delivering outputs that serve the project.
GICMEI is a French engineering consultancy and solutions design company working in France and internationally. Its core business — expert consulting and technical assistance — draws on extensive experience in railways, energy and automation.
Its scope also covers industrial and commercial facilities, public works, aerospace, automotive engineering, prototyping and digital technologies, including software and hardware. The company provides consulting, studies and audits in digital and emerging technologies, independently or with partners.
02 / TECHNICAL EXPERTISE
Understand each asset.
Manage its interfaces.
Anticipate how it will operate.
From design to delivery: 1,500 V DC and 25 kV AC overhead contact lines, light rail OCS and rigid overhead conductor systems. Setting-out, dropper design, installation schedules, track and civil works interfaces, access and maintenance.
Design and review of high-voltage, medium-voltage, low-voltage and traction power architectures: grid connections, transformation, rectification, protection, auxiliaries and continuity of supply.
Functional analysis, PLCs, safety automation, SCADA and remote control. Consistent commands, status feedback, alarms, sequences and human-machine interfaces.
Earthing, traction return, stray currents and EMC. Assessment of energy, signalling and operations interfaces, considering CBTC and ETCS / ERTMS principles.
Operability, maintainability, availability and safe interventions. Degraded operation, isolation procedures, return to service, documentation, FAT / SAT and acceptance.
Automation, supervision and industrial IT. Our development incorporates industrial and digital cybersecurity: risk assessment, protection requirements and security considerations from the design stage.
03 / HOW WE WORK
Team reinforcement, advisory, studies or management:
a scope and deliverables tailored
to each assignment.
04 / STANDARDS & ENGINEERING PRACTICE
Assessing a solution means connecting project requirements, applicable standards and actual conditions of use. Our approach combines technical justification, traceability and an operations and maintenance perspective.

05 / SMART & GREEN MOBILITY
Smarter mobility
starts with a better understanding
of its resources and energy.
Railway digitalisation, supervision, data and systems coordination. Bringing digital tools closer to the capacity actually available on the network.
Investigating energy efficiency, storage, smart grids and renewable energy integration, while considering safety, maintenance and the asset life cycle.
Exploring AI for document analysis, knowledge management and technical decision support. Studies and proofs of concept guided by domain expertise.
Technology creates value when it improves service, energy management and infrastructure resilience.
↗TRUSTED DIGITAL SYSTEMS / DEVELOPMENT FOCUS
Infrastructure digitalisation requires performance, service continuity and system protection to be addressed together. GICMEI is developing its support for industrial and digital cybersecurity challenges.
IT / OT risk assessment, requirements definition, access management and coordination with engineering disciplines: the skills mobilised are defined according to each assignment’s scope.

A RESEARCH INITIATIVE BY ISSAME GARCHALI / GICMEI
A route can exist without the network being able to accommodate additional passengers. The DROC framework explores multimodal orchestration based on the capacity that can actually be mobilised when passenger flows reach the different networks.
This capacity considers asset condition, operations, maintenance, energy, resources and existing commitments. The project proposes a federated approach: each operator retains its critical systems and decision-making authority.
Describe current and forecast capacity, its horizon and uncertainty; compare demand with physical constraints; and investigate the coordination of alternatives during disruption, while preserving safety rules and operator governance.
The validation programme includes a systematic review and comparative simulations. Research themes connect multimodal mobility, resilience, data, digital twins and systems optimisation.
Work in development. Conceptual framework not peer-reviewed; performance remains to be demonstrated through systematic review and comparative simulation. Preprint v1.1, 24 August 2026.
