Mechanical & Electrical Trades

Mechanical and electrical trades carry most of the certification and inspection load on an industrial site. Welding grades, rigging, pipe fitting and panel work are all scrutinised before a permit is issued, so these are the requests where documentation and worker screening matter most.

23 documented trades

Direct answer

Gulf Orbit supplies 22 mechanical and electrical trades across Saudi Arabia, including 6G X-ray welders, TIG and MIG welders, pipe fitters, riggers, industrial electricians and HVAC technicians, for oil and gas, petrochemical and industrial maintenance work.

    A complete RFQ gets a priced quotation, or an acknowledgement with any questions needed to price it. Responses run on working days, Sunday to Thursday.

  3. 3

    Worker matching

    Workers are matched to the trade and to the site conditions — industrial versus building work are not interchangeable, and we do not treat them as such.

  4. 4

    Documentation and client approval

    CVs, iqama and trade documentation, with TUV or Aramco card copies where the trade holds one, are submitted for your review. Nobody mobilizes before you approve the profiles.

  5. 5

    Quotation and purchase order

    Commercial terms are issued against the confirmed scope. A purchase order is required before mobilization.

  6. 6

    Mobilization within 48–72 hours of the PO

    In-Kingdom personnel travel to sites anywhere in Saudi Arabia, subject to worker documents and site approvals. Every worker completes Gulf Orbit's safety induction before deployment, and is briefed on your site's permit-to-work and access requirements.

  7. 7

    Ongoing support

    Attendance, replacement and scale-up handled through a single point of contact for the duration of the requirement.

Documentation supplied with every worker

Iqama, identification and trade documentation are available for client review before mobilization. Where a client requires a specific certification or a trade test before a worker is accepted on site, say so in the requirement and it will be addressed during matching rather than after arrival.

Send your manpower requirement

Trade, headcount, site location, start date and duration. The more detail you send, the more precise the response.

Frequently asked questions

What types of workers can Gulf Orbit provide?+

The published register lists 57 documented trades across civil construction, mechanical and electrical, and site and office staff, from scaffolders, welders and pipe fitters to crane operators, supervisors and HSE officers. Any mix can be requested in one RFQ.

Do your workers hold TUV cards or Aramco certification?+

TUV-carded workers are available for trades that require a TUV card. Aramco-certified and non-Aramco workers are both available. Card copies are sent with CVs for your approval before mobilization. TUV cards apply to trades such as scaffolders, riggers, crane operators and forklift operators. State in your RFQ which your site requires.

Which rigger level do you supply?+

Level III riggers, who sling loads and signal the crane. Level III is the rigger level Gulf Orbit supplies. State in your RFQ the lift type and any card the site requires.

Do you supply crane operators?+

Yes. Gulf Orbit has supplied operators for mobile cranes from 25 t to over 250 t (truck-mounted, rough-terrain and all-terrain). Tower crane operators are also on the register. State the crane type, capacity and any card the site requires.
