Marking Plates

Tunnel marking plates provide permanent identification for precast concrete tunnel segments, supporting traceability from manufacture through handling, transport and installation. They allow individual segments to be identified when required during construction or later inspection.

RFID marking plates can include segment reference numbers, production batch information and other project-specific traceability data. The information included can be defined according to the project’s identification and quality requirements.

Traceability allows an individual tunnel segment to be linked to its production batch and manufacturing information. If a quality issue is identified, this can help project teams quickly identify affected segments and support further investigation.

Yes. Optimas International can supply marking plates specified around the requirements of the individual tunnelling project. Factors such as plate design, material, fixing method and data format can be defined according to the project’s traceability requirements.

Marking plates are typically fitted or cast into precast concrete tunnel segments during manufacture. Incorporating the plates at this stage helps ensure the identification remains with the segment throughout subsequent handling, storage, transport and installation.

Yes. Permanent segment identification can support quality control, post-construction inspection and asset management by providing a clear link between an individual tunnel segment and its production information.

Marking plates can be used on metro, rail, road, utility and sewer tunnelling projects where individual precast concrete segments need to be identified and tracked throughout manufacture and construction.

Optimas International works with project teams to define marking plates around the required identification data, material, design and fixing method. This helps ensure the plates provide clear and durable identification suited to the project’s traceability requirements.
