1) Understand your process before you engage in building a cleanroom.
2) Gather a team from all disciplines — manufacturing, quality control, compliance, purchasing, facilities — who will understand the expectations of both you and your customers. Prepare for expansion now … don’t wait until later.
3) Prepare the scope of work required.
4) Make sure you are working with a qualified engineering team and builder.
5) Get a certifier involved as a member of your team. 
6) Archive all documentation throughout the pre-design, design, and manufacturing processes. Documentation from close out is imperative for moving forward. Expect and demand great close out documents.
7) Negotiate fair progress payments.
8) Check the financials of the contractor and their subs, to make sure they can carry the project costs.
