Lightning protection to extension on existing building

gibb01

Hi all,

We're carrying out The electrical install to an extension onto a farm shop.The Existing building is single story, metal framed with a metal apex roof & existing PV on top. There is essentially a new wing being bolted onto it. We are also carrying out the design and I've had a lightning protection company come  to do an RA to see if and what level it should be installed. 

The risk assessment has come back as lightning protection being required. However, the client has done the usual thing and questioned why it's needed when the building has been standing for 15 years and never been struck by lightning etc etc.. So much so that they've said they're not willing to pay for it.

As we or designing the electrical installation for the new part of the building, I'm not sure where this leaves us from a legal standpoint. Other than getting the client to sign a disclaimer stating they're aware of the risks and are still happy to not have it installed. We can't force them to have it installed & It puts us in a difficult situation! 

Has anyone else come across anything like this? Any feedback would be very welcome!

Thanks,

Tim

  • There is a standard provided by Furse which can be used to determine if protection is required. I suggest that a copy is given to the customer for their rational decision. 

    Many factors need to be considered though; having stayed in the South African Highveldt for many years where lightning storms with heavy downpours occurred most afternoons, during their summer, I witnessed the damage done, especially to tall trees when the bark was completed stripped off, also the inductive effects of strikes near wire reinforcing in concrete walls et al.
