Tunnel Inspections

Project information

Project description:

In order to establish the state of maintenance of various engineering structures, Rijkswaterstaat (Department of Waterways and Public Works) ensures that they are inspected on a regular basis. Delmeco has performed various NEN 2767 condition inspections on E and  M installations. The condition inspections verify the quality of the maintenance parts of the engineering structures.

Inspections were performed on various componential installations of the following engineering structures:

• Traffic centre Noord West Nederland;
• Wijker tunnel;
• Schiphol tunnel;
• Zeeburger tunnel;
• Engineering structure 502.

For these engineering structures, the following installations were inspected:

• Supply installation;
• Lighting;
• Traffic control installation (overview/CO/SOS/matrix);
• Ventilation;
• Cameras.

The assignment consisted of:

• Studying object information;
• Drawing up health-and-safety plans;
• Drawing up an inspection plan (work method, procedures and employment of people);
• Organising traffic blocks, road cordons and / or switching off (componential) installations;
• Drawing up the definitive inspection plan and lay-out of the inspection report per object (in accordance with 2767);
• Execution of condition inspections of the various installations;
• Drawing up inspection reports per object (including advice).
