Survey stakeout sketch
We've got our regular survey company mobilizing to start the stakeout next week. They forwarded me the stakeout sketch, which is something I have yet to receive on previous jobs. It shows much of the key information used by the excavator.
The notes in red are the cut lines that are transposed over the basement shape. The bullseye points are where stakes will be hammered in the ground. The stakes are offset from the hole so that when working, the machine does not destroy the markers. The excavator will make the hole larger then the actual shape of the basement because the cribbers need to walk around the perimeter to set their forms.
