Understanding problem with our construction plan

Just upload the plans.

Good evening,

Hello! I thought I understood our construction plan... If, for example, one side of the house is specified as 11.50 m in the detailed construction plan, is that with or without insulation (14 cm on each side)? I read the plan so that the 11.50 m are exactly the boundaries of the exterior walls. Then there is a line on the plan and outside it says 14 on the right and left for the insulation. The shell builder now claims that the measurement includes the insulation. Strangely, we are missing about 25-30 cm on the ground floor!
How is it in practice now? 11.50 PLUS 2 x 14 cm insulation (that's how I read it) or 11.50 m including the 2 x 14 cm insulation?

I have attached to you, for better understanding, the execution plan (what you probably call the detailed construction plan) for one of our ground floors.

The last, i.e., the outermost lines each mark the absolute width/length of the ground floor, the line below (i.e., towards the masonry) shows the measurement including the division of masonry plus outer plaster. We are building purely monolithically, so this value is rather small at 2.5 cm.

If your plans look similar – which I assume, since this corresponds to usual practice – the shell builder is absolutely right. We (all contractors) usually fully exploit the building envelope approved by the building authorities – at least in terms of width; these must not be exceeded by an insulation system either.

However, there must be – aside from that – a proper contract or certainly a building permit. The values of the execution plan should be reflected in this plan.

Rhenish regards

What are you actually talking about? One time you write insulation 14cm, another time monolithic. If I base it on your 25-30cm and then 14cm x2 we have 28cm. If I calculate your 10.70 inside the basement, plus your insulation that is probably present in the basement 28cm, I round up to 11m + 2 exterior walls at 25cm each makes Tara 11.5m

Without seeing the plans here, that doesn't make any sense.

yup, the link to the plan doesn't work for me
