Here are some shots of about 40 columns that needed offset points placed on a tight residential site on a steep slope, needed about 160 masonry nails at 0.5m offsets to get them all lined up for the shutter guys tomorrow morning.
Staked using only the column center points and stake to line or stake to offset line routine on the controller. All the columns need to be on the same axis's for this to work. Radial stakeout is the only way to go on this site.
The cages get in the line of site of the robot, but we could just push the cage over slightly to rectify.

What is the purpose of the offset nails ?
Is it to set out the concrete forms ?

PS-
Did the pre-packaged snow arrive yet ? 😉
The formwork guys use it to line up the column forms for position and orientation, they seem to prefer this method to staking out the grid lines, shooting chalk lines onto the deck and then measuring off them to get a similar result.
The offset nails are much quicker than the gridline method.
The snow did arrive...only about 120 km away got the first falls, but upcountry got a lot.
We hit our highest peak instantaneous power demand last night....so it is really cold up north.

That's a steep site?
You can hardly see over the roof of the house downhill. That's called flat here.
Well the driveway has a 34 % gradient which is double the recommended gradient, there are not many public roads that have steeper gradients than that.
Here the recommended max. grade is 15% for roads and driveways. So to get a permit you write a note "grades not to exceed 15%" then build whatever you like.
There are public roads up to 35%, Driveways and private roads up to 45%. People die on them on occasion.
There is one 45% private road where a track hoe slid down and over the edge. The operator jumped out, but 5 years later, the machine is still down there somewhere.
I walk away from jobs with roads or driveways above 30%.
