This is standard practice these days & the primary clients legal people seem to have their clients liabilities etc. well protected and 'proximity' for the client is at a long distance so the client should be safe as liabilities etc. will fall to the FM company - morally this may not be correct but who cares about morals anyway. As for an FM company managing the said contractors to what U would see as a professional system well that is another question and as for the HSE/EHO's; well enough said!

As long as the client has some sort of reasonable managing system in place that they use for their FM company they should be safe so if U are in doubt check it out & on a day to day basis if U have concerns go to the FM company and those in your company who procured their services also give day to day on the ground problems to the managers on the spot to sort as that is part of their job best of luck

This applies to me and I cover this by working closely with the outsourced contractor. We conduct contractor monitoring of their high risk activities and audit their documentation at regular intervals. Hopefully I am seen as a friend rather than foe.
