Your expert in independent checking engineer/Independent certifier services

We perform Construction Technical Control, External Control*, or  Independent Checking Engineer/Independent Certifier(ICE/IC) services.
As an independent third party, we ensure, during Design, Manufacturing, Installation, Tests & Commissioning activities, that standards, regulations or state-of-the art rules are complied with, and that the client’s specifications are reached for the whole transportation system.

Please find here below all possibilities, and contact us for any additional information.


For the whole system (Rolling Stock, Control-command & Signaling, Energy, Infrastructure, Global System), we assesse, within its independent control mission, the compliance with the client’s specific requirements.
We also assess System Integration aspects (transversal requirements & interfaces).


For Civil Works & Buildings activities, CERTIFER assesses buildings’ solidity (foundations, structure, facade) as well as the compliance with regulatory rules in terms of fire protection (egress, emergency services access, smoke evacuation…), and the accessibility to persons with reduced mobility. Such service also includes acoustic & thermal isolation, and the installations’ global functioning.


We also support you in assessing Requirements Management all along the project’s life.

Using tools that are dedicated to this emergent discipline, we are able to help you in implementing an efficient, reliable & optimized requirements management for any type of project. On top of implementing all basic concepts, we can also monitor those requirements, and ensure that such are covered accordingly using proven development processes (EN 50126).


For other types of systems: Rolling Stock, Signaling, Control-command…, CERTIFER starts its external technical control by assessing their respective safety, then their compliance with the client’s specifications.
