Frequently asked

Questions our clients ask most often.

What makes inspection “third-party”?+

A third-party (Type A) inspection body is independent of the designer, manufacturer, supplier and user, so its verdict carries no conflict of interest. GCS operates an ISO 17020-aligned inspection scheme on that basis.

Is GCS a LEEA member?+

Yes. GCS is a Full Member of the Lifting Equipment Engineers Association (LEEA) and operates an ISO 17020 inspection scheme — the de-facto standard for credible lifting inspection in Oman.

What certification do you issue?+

A formal report with photographs and findings plus a Certificate of Conformity citing the specific clause references. Hard-copy and electronic certificates are available, and records are retained for audit.

How quickly can GCS mobilise third-party inspection and certification in Oman?+

For routine work in Muscat, Sohar or Duqm, mobilisation is typically within 2 working days. Emergency and field jobs can be mobilised same-day, with reports issued within 5 working days.
