The IIS Group boasts nearly 60 qualified inspectors, most of them employed in IIS SERVICE and in IIS CERT, which are able to perform different type of inspections and supervision: during fabrication and erection, in workshop and worksite, performing NDT, QA/QC services, expediting and, finally, second and third party inspections.

All our inspectors are equipped with our distinguishing expertise and professional requirements as well as adequate qualification for their tasks.

Herebelow the international qualifications of our inspectors:

The added value we can offer during our inspections is not only in the expertise of our own inspectors but also in the ongoing links between our site inspectors and our technical departments: Engineering, NDT, Technical Assistance, Laboratory, Certification, Education and Training. These departments are able to give technical support and assistance to smooth different issues which can arise on the job.

The IIS Group performs inspection activities in different industrial segments, Oil&GAS, Infrastructures, Transportation and, generally, in all industrial fields in which welded components, structures, equipment are manufactured and supplied.

At shortest notice our inspectors can be operating at any location, in Italy and abroad, in workshop, construction yards and plants, to perform inspections and tests on pressure equipment, steel structures, piping.

We operate by our own personnel and this has always been recognized as a strength point by our Clients.


When a single IIS inspector is on site, the whole IIS Group is virtually there!
