What criteria are mentioned for selecting a subcontractor?

The selection criteria include facilities, knowledge, and experience, along with the selection process itself.

What should the working arrangement with a subcontractor cover?

The working arrangement may cover technical requirements (for parts to be designed or tasks to be performed) and process requirements (e.g., procedures to be followed by the subcontractor).

How can a declared design organisation take into account a partner or subcontractor holding a design organisation approval (DOA)?

The declared design organisation may take the DOA into account for the effective integration of that partner or subcontractor, for example by simplifying the selection process when the scope of work of the subcontractor's DOA is similar to the scope of the subcontracted work.

GM1 21L.A.174(b)(3)

Q: What elements should the process to control partners and subcontractors normally address?

The process should normally address: identification of the work to be subcontracted, selection of a subcontractor based on its capability, the working arrangement (e.g., purchase technical specifications, statement of work), and the control of the work performed by the subcontractor.

Q: What does the control of work performed by a subcontractor cover?

The control covers the deliverables provided by partners and subcontractors, the monitoring function required under point 21L.A.174(c), and, if relevant, the independent function to verify the demonstration of compliance required under 21L.A.174(b)(2).

Q: If the independent function to verify the demonstration of compliance is subcontracted, what should the declared design organisation identify in its own documentation?

The declared design organisation should normally identify in its own documentation the authorised staff of the partner or subcontractor performing this function.

PARTNERS AND SUBCONTRACTORS

Examples of elements that the process to control partners and subcontractors should normally address are:

— the identification of the work to be subcontracted (e.g. design of parts, drafting drawings, stress analysis, laboratory testing);

— the selection of a subcontractor based on its capability to perform the identified work (criteria (e.g. facilities, knowledge and experience) and the selection process);

— the working arrangement (e.g. purchase technical specifications, statement of work); this may cover technical requirements (for parts to be design or tasks to be performed) and process requirements (e.g. procedures to be followed by the subcontractor); and

— the control of the work performed by the subcontractor; this control would not only cover the deliverables provided by the partners and subcontractors but also the monitoring function required under point 21L.A.174(c), and, if relevant, the independent function to verify the demonstration of compliance required under 21L.A.174(b)(2).

If a partner or subcontractor holds a design organisation approval (DOA), then the declared design organisation may take this into account for the effective integration of that partner or subcontractor (e.g. simplifying the selection process when the scope of work of the respective subcontractor’s DOA is similar with the scope of the subcontracted work).

The declared design organisation maintains a list of all selected partners and subcontractors, including their respective scope of subcontracted work.

If the independent function to verify the demonstration of compliance required under point 21L.A.174(b)(2) is subcontracted, the declared design organisation should normally identify in its own documentation the authorised staff of the partner or subcontractor performing this function.
