Comparison of construction performance description! What should we prefer?

Hello, I think you should always renegotiate the prices. If you tender according to [LV], you can quite well compare the prices and, if necessary, push down positions in price. I have two acquaintances who, as civil engineers, often tender a lot to subcontractors... every position is renegotiated there... We are building with an architect and individual contracts, and so far we are keeping our budget well. Many positions can be executed to a higher quality for the same price than with the developer.

I also think that architect + individual contracting is the most cost-effective option. With your all-inclusive offers, you still have no idea what you are getting. What building materials will be used? What kind of heating? Sanitary equipment? How much electrical work (sockets per room, network sockets, etc.)? In the end, you still have no comparable offers available. I will give you the advice again: Find an architect or civil engineer. Have them prepare the construction plans and tenders. You then send these tenders to various companies in the area so that you receive at least 3 offers per trade. Now you have a very good overview of what your house will cost and can estimate whether cuts need to be made or not. Now I would bring an independent site manager on board. This person compares the offers, negotiates further, and awards the contracts. Here I would insist that VOB contracts with fixed prices are negotiated and that the ancillary construction costs are also borne by the individual craftsmen. During execution, the site manager can supervise the construction site and inspect the trades.

Hello,

..... and also the incidental construction costs borne by the individual craftsmen.

Which costs exactly are meant by that?

Best regards from the Rhineland

I have included: 0.3% of the gross contract amount for construction electricity and water. Waste disposal is not borne by the client but by the contractor. In addition, 0.2% of the gross contract amount for the builder's liability insurance. Additionally, a 0.2% deduction per working day of delay but a maximum of 5% deduction. Additionally, 2-3% discount, depending on negotiation skills. And a security deposit of 10% of the gross contract amount for contract fulfillment. So far, all reputable craftsmen have signed this way and the construction project is almost finished. The budget was almost a perfect match. 2000€ are "left over".

Then I know what you mean; this is a completely normal procedure for individual contracts – also that you have to place the 10% retention in a separate account and possibly earn interest on it.

However, your contract has little in common with the usual ancillary building costs; that is why I asked for an explanation.

Who checks the craftsmen’s invoices?
