Are all control appointments from the construction supervisor (BHS) necessary?

Hello everyone,

for our construction project, we joined BHS and now have a construction supervisor there. He has noted the following inspection appointments in his contract. Since each appearance costs money (travel, inspection, return trip, follow-up), I wanted to know if, from your point of view, all the individual inspections are really necessary? There are apparently 8 inspections, during which a total of 13 topics are reviewed.

[*]Inspection of foundation work / base plate before concreting the slab
[*]Inspection of basement walls after waterproofing / before backfilling the excavation -> we do not have a basement
[*]Inspection of shell construction after erection of the roof truss
[*]Inspection of roof after roofing and roofing sheet metal work
[*]Inspection of windows after installation and before interior plastering
[*]Inspection of rough installation of building services before concealing the lines
[*]Inspection of interior plaster / drywall (*)
[*]Inspection of screed preparation before installing screed
[*]Inspection of tiling work after waterproofing sanitary rooms and before tiling
[*]Inspection of facade work (*)
[*]Inspection of interior finishing (*) / inspection of building services (*)
[*]Pre-inspection for final acceptance (*)
[*]Technical supervision for final acceptance

(*) in connection with other inspection appointments

Estimated costs according to the construction supervisor approx. €3000.

What would you want to cancel? I can't think of anything.

Well, if those are the standard dates, I wouldn't deselect anything. Only if someone were to say "This checkpoint is completely unnecessary because you can't see anything there anyway." If such feedback doesn't come, of course I'll leave it as is.

Either you can and do it yourself or you trust the man.
Everything in between doesn't help much.

Well, you don’t have a basement, as you’ve already recognized yourself, but then there will be an intermediate ceiling inspection before concreting. I would have him come again before the ring beam is poured. Basically, better to have him come once too often. The money invested can be worth its weight in gold, especially if you’re not familiar with it. But have a look at it beforehand and have the execution documents and construction performance description checked. The experts are all different. Ours from BHS was a bit clumsy, but he looked everywhere and questioned everything. Continue the inspection protocol until the end and attach it to the acceptance protocol. Discuss the procedure beforehand with the BL from the GU.
