They are not a licence to practise engineering and do not grant legal authority to certify, stamp or seal engineering work in any jurisdiction. Where local law requires a registered or licensed professional to sign off a design, that sign-off must be obtained from a professional registered in that jurisdiction. Clients remain responsible for confirming that the engineer they engage holds the authorisations their project requires.

Questions

Hiring for process engineering

What should I include in a process engineering brief?

State the asset or system, the project stage, your jurisdiction and applicable standard, what inputs you can provide, what deliverables you need back, whether site attendance or professional sign-off is required, and your timeline and budget model. The intake asks all of this and produces a structured statement of work.

How is pricing usually structured for this kind of work?

Well-defined work is normally fixed price with a stated deliverable list. Larger or less certain scopes run as milestone projects, funded milestone by milestone. Ongoing support runs hourly or on a retainer. Every model is supported here.

What if nobody in this exact discipline is available?

Disciplines are related in the taxonomy, so adjacent chemical, process, biochemical & industrial process specialists are surfaced automatically. You can also post the project and let qualified engineers come to you, which is usually faster for specialised work.
