Hi Karan

In a previous posting you indicate that you have attained the NEBOSH General Certificate, so you should be aware of some of the fundamental document requirements of the Health and Safety at Work etc Act 1974 and the Management of Health and Safety at Work Regulations 1999 amongst other legislation that is as applicable to constuction as other sectors.

You also indicate that you are aware of "CDM", so perhaps time to familiarise yourself with HSE guidance L153 and perhaps compare Part 4 of CDM with the requirements of the Workplace (Health, Safety and Welfare) Regulations 1993.

That would give you some clues as to what the "main documents" for H&S in construction might be.

BUT, why would it be an H&S professional creating these and not the line management chain of command?

Plenty of construction projects operate entirely appropriately without site based H&S professionals and have done so since decades before the first iteration of CDM.
