Is the general contractor payment plan acceptable? Thanks for tips

50% after completion of the shell including windows is wishful thinking and hardly enforceable. however, the plan here is significantly worse and does not at all reflect the costs per construction phase (e.g. 14% for screed).

50% after window installation is somewhat ambitious, but not that far from what is actually possible. Our construction contract provides for an initial payment of 48% after roofing, with 5% held as a security deposit according to the Building Code. Another 17% after heating installation and sanitary/electrical wiring and window installation... Short version: I personally would never accept the mentioned offer.

To avoid having to start a new thread, I would like to join in here.

We have received the payment plan from our general contractor, with the following proposal. Discussion and changes are potentially possible if they remain within reasonable limits.
What do you think about it?

Payment step	Percent	Cumulative percent
1. After contract signing	2.4%
2. Concrete slab laid	8.0%	10.4%
3. Ceiling above basement concrete	15.4%	25.9%
4. Ceiling above ground floor concrete	16.0%	41.9%
5. Completion of shell construction / roof	16.0%	57.9%
6. Completion of windows / interior plaster	16.0%	73.9%
7. Completion of interior work	16.0%	90.0%
8. Completion of exterior plaster	5.0%	95.0%
9. After acceptance	5.0%	100.0%

Anyone have a hint or an opinion on this? I would appreciate it.

Completely overpaid before the expensive technology is installed. But that's how it is with almost everything.

Thank you for your response.

The general contractor was open to changes in the payment plan in the last conversation. What would be your recommendation or for which steps should one go down and where up?

This would be ours for comparison:

1. Interim payment of 05 % after the start of earthworks
2. Interim payment of 10 % after concreting the floor slab
3. Interim payment of 10 % after the load-bearing masonry on the ground floor
4. Interim payment of 10 % after the load-bearing masonry on the upper floor
5. Interim payment of 10 % after erecting the roof truss
6. Interim payment of 08 % after roofing
7. Interim payment of 07 % after installation of windows
8. Interim payment of 05 % after interior plaster
9. Interim payment of 10 % after rough installation H/S/E
10. Interim payment of 05 % after earth deep drilling
11. Interim payment of 05 % after drywall
12. Interim payment of 05 % after 1st and 2nd layer of exterior plaster
13. Interim payment of 05 % after installation of stairs & interior doors
