Groundwork & Foundations Question

Squew foundations - what do i do now ?

I am building a 3 m X 5 m Rear extension.

I have done all drainage and preperation to now start laying courses for block and beam floor.

Even though I marked the footprint to be squsre and painted lines to follow.

Due to Water board holding up works as a Psewer was found for one day to fill the trench the walls collapsed due to the weather and forgot about square when shuttering and filled trench.

Now I have come to lay the first course square I have found the shuttering in square and all footings accross the face and are slightly squewed by 150nm.

This results in the intenal wall hanging close to the footings.

BCO have approved the footings but I only realised this situation yesterday.

Any suggestions what I can do.
I do not want to dig out the footing as it is gen 3 and 700 mm deep.

BCO are not aware of the above but have advised originally I can only build centrally on footings.

Any help will be much appreciated.

Looks like you know what you are doing if you are doing the brickwork and "were" planning to the foundations yourself but "employed a groundworker" instead to "save you digging"

You should also know the answer involves a fulcrum.

What a balls up! Make the building a tad smaller to suit the footings otherwise pull the lot out, start again do a proper job, it's a small cost to bear now rather than 5 years down the line when your building starts to crack and subsides leading an expensive underpinning job, that's if you risk it and try to 'get over' the problem by digging along side the trench, you may have got over problem if it were the external skin but the internal wall bears the weight of the whole house, Especially if your going double story!!
