Level, where art thou level..?

Level has been finalized to within about 1mm accuracy. The laser level is extremely accurate. More then we would even need it to be for this. The concrete will not even be this flat to even warrant such accuracy I think. This section of the house is the footing which is under ground by 1m at least. Here are the finalized levelled slam formwork pictures. You can see the lowest point of our base course is about 9cm or 3.5 inches higher. If you don't want to dig out that section then this means you need to raise all the formwork higher so the bottom becomes level with that point. We will backfill with rock to prevent concrete from pouring out of course.
