Verification directory
Instead of name lists that go out of date, this page links to the official bodies where you can verify an engineer, contractor, engineering office or laboratory yourself before you sign, with what to ask for each one.

Engineers
What to check: Before you sign: ask for the engineer membership number, verify it, and check that the discipline and grade suit the work.
Contractors
What to check: Before award: check the commercial registration and that the contractor classification covers the field and the grade for the project value, and ask for similar past work you can visit.
Engineering offices and building permits
What to check: Permit drawings are stamped by an engineering office licensed in Saudi Arabia. We prepare the design and shop drawings, and the permit file is submitted through a licensed office.
Soil and testing laboratories
What to check: Ask for the laboratory accreditation certificate and its scope, and check that the test you need (soil, concrete or steel) is within that scope.
Fire and life safety
What to check: Fire protection drawings are approved by the authority through an office accredited with it. We design and coordinate MEP systems and prepare occupational health and safety plans for projects.
Subcontractors and suppliers
What to check: We ask every supplier and subcontractor for the commercial registration, Zakat and tax certificate and past work before any purchase order.
