Separate procedures for contractor and subcontractor

For clarification, we are a telecoms infrastructure provider. We do site build that involves civil and telecom works.”

Answer:
There is nothing in clause 4.2 of ISO 9001:2015 that forbids an organization of doing what you want to do. More, there is no clause in ISO 9001:2015 that goes against that practice.

What I recommend in each procedure is being very clear about the scope of application.

I can think that you r company and its subcontractors want and are concerned with quality control, cost control and time control. I can imagine a situation where your company is OK with quality and time performance but wants to improve cost control performance. At the same time, for your company as long as subcontractor’s quality and time control are OK, cost control is not a problem because your company only pay what was agreed. One can imagine a situation where subcontractors control costs more effectively than your own company and improving cost control is not a priority.
