Underpinnin due to additional load

Currently adding a floor to a flat roof building. A small section of wall requireds underpinning due to the additional load being added.

Is this treated in the same was as underpinning due to subsidence by insurers and mortgage lenders?

    I did the same some years ago. It wasn't on the plans or mentioned by the planning dept, but the council building inspector said "he'd be happier" if a section of wall was underpinned, so I kept him happy ;)

    It was never mentioned, I was never asked by anyone, only me and the building inspector knew . . .

    ps: it's still standing :)

    No. The problem with "underpinning" is simply that it's usually done in response to where the problem really lies. Subsidence...

    Underpinning because of subsidence is an after-the-horse's-bolted repair.
    Underpinning while extending is a preventative upgrading of the foundations to take the additional load.

    Depends on the questions the insurer asks.

    Web/Comparison sites will probably go as far as "Has the property ever been underpinned?" Which you would answer yes to and the cost would increase.

    You will be able to find cheap quotes still but would need to engage with someone! And a minimum wage drone will be no better than a web site here you need someone who can actually do things. Easiest would be a (real) broker.

    The question insurers usually ask is 'has itnsuffered with subsidence' rather than 'has it been underpinned'. However, even if the question were about underpinning I would still answer 'no' as it is effectively a new foundation for the new extension and will be acknowledged by building control as such.

    [FONT=Verdana, sans-serif][FONT=Verdana, sans-serif]1 - The property has not previously been underpinned or otherwise had its foundation reinforced?[/FONT][/FONT]
    [FONT=Verdana, sans-serif]2 - The property has never shown any signs or been monitored for subsidence, landslip or heave?[/FONT]

    So that would be disagree to the first, agree to the second.

    I'd still agree that it hadn't, because I am cynical of that questionz. It should make no detrimental difference to their risk assessment of the property. Which is what those questions are seeking to do.
