Does anyone know if having the frame put up the day after the slab is poured will cause major issues? At 2pm Friday we went to check on the progress of our foundations & the slab must have been poured early that morning as it hadn't been there Thurs evening. Then the frame was put up on Saturday. A builder on a site across the road said it was greener than he would have done it, but he's seen it done before. Is this a big deal & if so what should I do about it?
