Coverage depends on:
Dilenza can also review inspection requirements in Ticino, Valais, Fribourg, Schaffhausen, Zug and other Swiss manufacturing locations.
Coverage depends on the supplier location, equipment, technical scope, required qualification, schedule and suitable inspector availability.
Inspector selection starts with the technical requirement.
Inspector selection should be based on the project requirements, including the applicable code, equipment type, welding processes, qualification level and relevant fabrication experience. Two inspectors can hold similar certifications while having very different experience with railway structures, pressure equipment, process piping, machinery or high-specification fabrication.
Step 01
Step 02
Step 03
Relevant inspector CVs and qualifications can be submitted for technical assessment.
Step 04
The confirmed inspector attends according to the agreed scope and schedule.
Independent vendor inspection in Switzerland can provide technical oversight before equipment leaves the supplier.
This can be particularly valuable for complex machinery and engineered equipment, where a final inspection alone may not provide enough visibility into critical manufacturing stages.
Depending on the client's ITP, inspection can follow:
Confirm the applicable technical requirements and inspection stage.
Verify material identification, certification and traceability.
Attend agreed manufacturing, fabrication and assembly activities.
Provide independent technical presence at project-defined milestones.
Witness defined tests or Factory Acceptance Testing when included within the scope.
Complete the agreed inspection before release or shipment.
Vendor inspection can help provide visibility into:
For international buyers sourcing technically complex equipment from Switzerland, inspection at the supplier can provide independent technical visibility before shipment or integration into the final project. Inspection frequency can range from one critical attendance to recurring manufacturing surveillance or resident technical presence.
Certification alone does not determine technical suitability.
Welding
Protective Coatings
Profiles can also be matched according to:
Equipment · Materials · Welding Processes · Manufacturing Methods · Coating Systems · Rail Experience · Process-Industry Experience · Applicable Standards · Assignment Duration
Depending on controlled project documentation:
The applicable code, edition, acceptance criteria and inspector responsibilities should always come from the project's controlled documentation.
Some industrial products and equipment in Switzerland are subject to legally defined conformity-assessment or inspection requirements. Pressure equipment is one important example. Dilenza's ordinary vendor and project inspection services should not be treated as a substitute for statutory inspection, conformity assessment or the involvement of an authorized body where this is legally required. The independent project-inspection scope should therefore be distinguished from any regulatory activity required for the manufacture, placing on the market or operation of the equipment.
