ᐅ Withholding Payments for Defects in the Shell Construction Phase

Hello everyone,

The ceiling above the ground floor has just been concreted on our site. According to the payment schedule, a partial payment of approximately €30,000 is due.

However, our expert has identified several defects. These were formally reported to the general contractor (GC) with deadlines. The first deadline (2 weeks) passed without the defects being resolved; the second deadline is still running until Thursday (also 2 weeks).

So far, we have withheld about €17,000 of the €30,000. Our GC considers this amount far too high and insists on payment.

Since we are currently concerned about the potential insolvency of the GC (the structural builder, brick supplier, steel supplier, and light well supplier have not been paid), we want to keep the deduction as high as possible. However, since we are not construction professionals and want to avoid the risk that withholding too much for defects could backfire, I hope that some experts here can provide us with a rough cost estimate.

P.S. Our lawyer has been contacted, but the appointment is only scheduled for 17.02, and I fear we cannot hold off the GC until then.

Defect 1:
At the transition between the basement and the ground floor, no damp-proof course was installed at the base of the first course of blocks.
The basement is already fully lined with Styrodur insulation, and the excavation pit has been backfilled.

Cross-section through a building wall with heated ground floor, foundation, insulation, and base plaster.


Defect 2:
In some areas of the structural shell, the minimum offset of the bricks was not observed; in places, up to 7 courses of bricks were laid directly on top of each other.

Construction site brick wall made of red bricks, visible mortar joints, upper foil covering the wall.


Defect 3:
This is a row house. Mineral wool boards were installed between the buildings for sound insulation. At one externally visible spot, there is a gap of about 80cm (31.5 inches) depth and approximately 20cm (8 inches) height between the boards. After reporting the defect, the structural builder just “stuffed” mineral wool boards into the hole. According to our lawyer, this does not reliably ensure soundproofing.

Defect 4:
The area where the patio doors will later be installed was cast in concrete. Here, the reinforcing steel protrudes from the wall. According to the expert: This means that a proper bond between the reinforcing steel and concrete is not sufficiently ensured. It is assumed that adequate long-term corrosion protection of the reinforcement steel is not established. Furthermore, with insufficient concrete cover over the reinforcing steel, adequate fire protection is not guaranteed.

Defect 5:
In the floor slab area, the mineral wool board was not properly secured. As a result, it is quite wavy. This is particularly problematic in the stairwell area, where in some places only 10cm (4 inches) of concrete remain above the mineral wool board. The partition wall bricks have a thickness of 17.5cm (7 inches), though.

Construction site: concrete beam with joint, sealing compound, wooden framework, and measurement marks.


Defect 6:
The mineral wool boards were not installed tightly enough in some areas, allowing concrete to seep between the boards and create a sound bridge.

These are the (known) defects so far. I would greatly appreciate it if anyone could roughly estimate the costs associated with these defects.

Thank you very much in advance.

Yes, it gets even more complicated because by assigning many tasks myself, I effectively reduce the general contractor’s contract sum, but these credits are not deducted from the overall contract sum for interim payment calculations. Instead, they are only applied to the corresponding scheduled interim payments. As a result, by the time the window installation trade is involved—which also corresponds to an interim payment stage—I am even at 81%. To be fair, the additional work does not increase the contract sum for the interim payments either; it only becomes due upon completion. Still, I will now always worry whether defect remediation will go smoothly, since my leverage is rather limited.


Have you made sure that the general contractor cannot charge you for lost profit due to your self-assigned work and the resulting reduction in his contract sum? Otherwise, he would probably be allowed to do so.

As long as the investigation is ongoing, actually no. Only after a final conviction.

According to the public prosecutor, there is reasonable suspicion.

That does not prevent a dismissal according to Section 154 (2) ;-)

§ 154
Partial suspension in case of multiple offenses


2) If the public prosecution has already been initiated, the court may, upon request by the public prosecutor, provisionally suspend the proceedings at any stage.

In cases of delayed insolvency filing, sale of an insolvent company, tax evasion, and undeclared work, it is rather unlikely. And if it does happen, the reason does not really matter; the main point is that he is removed from circulation.
