Hello,
we are building a Rensch prefabricated house and have contracted the foundation slab as a private job to a foundation specialist. He requires both rough and fine staking out to prepare the foundation slab.
We hired a licensed surveyor to carry out the rough and fine staking. The requirement was "[...] floor plan and site plan with the planned building marked [...]". We provided the plan from our architect, and there were no further questions.
The fine staking was done according to the building’s outer dimensions, but according to the foundation specialist, this is incorrect. He said the staking should have been done according to the foundation slab plan, which is a few centimeters smaller than the actual building.
Now I wonder, shouldn’t the surveyor know this if they do it every day? The correction was charged to me, but is the fault mine? Has anyone had similar experiences or can offer advice?

Answer from the former surveyor (me):
The staking out is based on what is specified. If that is not clearly defined, it’s hard to hold the surveyor responsible.
I do hope you at least took the effort to set up the batter board yourself! Driving some stakes into the ground can easily cost 200–300€ (around $220–330) ... and 200€ (about $220) for the fine staking out or additional work (another 8 nails) on the batter board is a bargain. Travel, setup of the total station, positioning, staking, documentation. The surveyor didn’t make much profit from that. :-)

This would avoid any uncertainty about responsibilities.https://www.instagram.com/11antgmxde/

The construction project manager named in the site manager declaration should ideally also be able to take on the role of the general contractor’s site manager for all trades provided by the client. This would avoid uncertainties about responsibilities.“Saving” is probably at the heart of the issue, since of course you can buy all of this.
