How and when is payment made?

why, you can also request offers as a private person. I write to the window builder that I want 10 windows with the size hüh and hot installed in city x and ask him what he charges for it. of course, a lot of own effort is necessary, but someone who is a bit proficient in CAD can already take a lot of initiative until he finally hires an architect.

I basically don’t like your posts, I am tormented by a certain aversion, even though it may partly be prejudiced.

Nevertheless, I wait patiently and eagerly for the moment when things maybe don’t go as smoothly for you as you imagine. When the problems start and the companies you hired are dealt with in the, let’s say nicely, "quirky," way typical for you.

This has nothing to do with anticipation, but rather that basically you can write whatever you want to me and you basically mostly think you know better. That creates in me a rare feeling of leaning back and wanting to watch. ;)

Voki, you are very empathetic. I cannot do that.

I basically agree with Lexmaul. The only way to actually offset this risk is to commission an architect up to the tender stage and use these tenders to obtain the offers. All other "offers" will, depending on the provider, be full of missing items. If there is also enough buffer on top of the buffer, you can do it roughly like that. But then I would have preferred to go to a general contractor and say: make me a complete offer. Then add another 20% on top and you would have a rough idea of where the journey is going overall. That would have a) been much faster, b) cost less time for everyone involved, and c) be just as right or wrong.

@ Payday... you should write to the window manufacturer with x windows, y measurements, z city... Apart from a tired smile and some wrong offers, nothing will come of it.

clear no problem, I work in design including project management in mechanical engineering and purchase all parts for machines (which I have previously developed), that exceed the cost of a house by a multiple. I know the principle of creating offers and awarding contracts, I go through it every day. and oh wonder it even works! you are of course right that as a private person it is much harder to get reasonable offers for things that you understand little or nothing about. nevertheless, you can obtain offers and there are companies that make reasonable offers based on them. you are acting as if an architect is performing magic and his prices for the house costs were state secrets. the pure aversion to my contributions could also come from the fact that I write here privately after work and don’t have to rely on the high-flown language of work. this is a forum, here you don’t have to write perfectly precisely. it’s often about experiences and recommendations here, not legally binding statements. and yes you are right, an architect is probably advisable if he already has to ask such things here. someone with some knowledge of the matter could also already make a somewhat more precise calculation without an architect and then use one later. that is exactly what people who build with a construction company do as well...

Good evening,

sure no problem, I work in design including project management in mechanical engineering and purchase all parts for machines (which I previously developed), which exceed the cost of a house by many times. I know the principle of preparing offers and awarding contracts, I go through it every day. and oh wonder it even works!

Talking to a mechanical/civil engineer about the topic of house construction is always a tiresome appointment, because members of this professional group are predominantly characterized by being resistant to learning and often appearing know-it-all. I am not asking myself for the first time whether there is a dedicated course for this at university or college.

In recent years we have built for some mechanical/civil engineers and it is unfortunately telling that – when problems during the construction project had to be solved – they were less due to negligence on the construction site. Therefore, Volker can relax, because his assumption will prove true sooner or later; also an experience from recent years :confused:

Rhenish greetings

Talking with a mech./civil engineer about the topic of house construction is always an exhausting appointment, because members of this professional group are generally characterized by their resistance to learning and often come across as know-it-alls. This is not the first time I’m wondering whether there is a dedicated subject for this at university or technical college.

In recent years, we have built for several mech./civil engineers, and it is unfortunately indicative that - when problems had to be solved during the construction project - they were less often attributable to negligence on the construction site.

Are there also concrete, anonymized examples? Asks curiously a graduate engineer (process engineering).

An architect does not perform magic, but he knows what should be included in the tender documents. And that is not just the window measurements...

Or shell construction tender - I want to see you get reasonable offers for that. You can develop impressive, expensive machines all you want, but you will experience failure.

You see the whole thing too simply and somewhat detached...
