Needing help from H&S Managers/Advisors working in the civil or construction sector, as I'm analyising resources and job responsibilities within our business.

Who in your team is responsible for writing and approving project health and safety plans (SSSPs)?

Do your Project Teams prepare your project H&S plans and then provide to your H&S Manager/Advisor for review/approval?

Or, is your H&S Manager/Advisor tasked with fully reviewing all project documents (which takes a lot of time) and preparing the plans from start to finish before providing the plans to your project teams?
