Seven locations across the Sultanate of Oman.

From Muscat to Salalah, Sohar to Sur — GCS mobilises certified inspectors, NDT technicians and HSE trainers from the location closest to your project. Choose your city below to view local services, contact and coverage area.

National coverage

Same standards. Local response.

Every location delivers the same ISO 17025-aligned, LEEA-member quality — but with the response time and local knowledge of a regional team.

Same-day mobilisation

For routine inspections in Muscat, Sohar & Duqm — same-day or next-day mobilisation.

Consistent quality

Every certificate carries the same accreditation footer regardless of which city issued it.

Local relationships

Long-term local presence means local knowledge of operators, sites and Omani regulations.

Lower mobilisation cost

Local crews mean less travel, less per-diem — and lower invoiced cost for routine work.
