Im not sure i understand what you are asking, surely if no-one is in the building then no risk as you put people in the building the you assess the risk to your people and put in appropriate control measures, or have I missed something???

GillR. Not everything has to be 'risk assessed'. I understand if that surprises you, as the H&S world seems to have become obsessed with this belief. The owners may well have assessed the risk to be 'insignificant' in which case, they have done what is required! However, in the real world, I find that assessing risk where people are doing stuff is the key. Your staff, your activities, your risk - your systems and controls. Premises can't really be 'risk assessed' as such - fire is the exception but fire is the risk, not the building. Buildings lend themselves to being managed by checklist (unlike people!). There is no legal obligation to risk assess toilets. There is a legal obligation to risk assess any signficant risk to people working in toilets. Despite all the talk about RA, the actual need is to manage. So you can apply your own 'checklist management' to establish that the building doesnt create harm for your staff. Others have given examples of what that might include. You can ask the landlord for their maintenance schedule of services, aircon, lifts, fire RA, etc. Contractor work you may have an interest in but only where there could be an interaction, which might be rare. On the other hand, are you going to bring contractors in who may mess with acm panels or fire detection? Fire RA should be the priority request from the landlord, as this will provide your office fire precautions. Hope this helps.
