Is worry justified or not?

Are you really going to let the purchase of the property fall through if the sand pile is not removed?

That’s normal. You buy it, it takes about another month until it’s yours, then you apply for the building permit, which takes another two months to be approved, then one or two months later construction begins. So the pile can sit there for almost half a year.

There will also be a wheel loader driving over it, and one, two, three trucks, and maybe a mobile crane will set up its supports or a container will stand there for three days. And maybe after the topping-out ceremony a carpenter will throw up on it.

And at some point you’ll get upset calls from the neighbor asking why you crippled his tree (and then find out that someone from your construction crew broke off a branch so the truck could get through).

@nails: one of the smallest hazards on the construction site. By the way, for 20-30€ you can get puncture-resistant boots with steel toe caps. For the big guys carrying the little ones in their arms.

I also have children, yet I advise that you need to relax considerably during the house construction period, otherwise it will be very stressful for you... This is a truly well-intentioned piece of advice, without any irony or the like.

You build for hundreds of thousands. Sometimes disposing of 200€ worth of garbage that someone “forgot” there is part of the business. Please don’t make a big deal out of such trivialities. This simply isn’t a project with a fixed price guarantee. There’s always something and a bit of loss anyway. You’re free to put up a construction fence or similar once it’s yours.
