Q1. How much are the design charges? |
A1:
The design control charges are decided based on former Ministry of Construction notification 1206.
Our drawing office calculates design control charges in consideration of a kind, a degree of difficulty, the area of the building to a base in this 1206, too.
The following tables are approximate indications, but please refer to it.
| Construction construction cost | Design control charges |
| In the case of a construction construction cost to 20 million yen | 2 million yen |
| In the case of the construction construction cost to 20 million yen - 30 million yen | 10% of construction construction costs |
| In the case of the construction construction cost to 30 million yen - 50 million yen | 9% of construction construction costs |
| In the case of the construction construction cost to 50 million yen - 80 million yen | 8% of construction construction costs |
| In the case of a construction construction cost to 80 million yen - 10,000 ten thousand Japanese yen | 7% of construction construction costs |
| In the case of a construction construction cost to 10,000 ten thousand Japanese yen - 30,000 ten thousand Japanese yen | 6% - 7% of the construction construction cost |
●Of a building "examines the structural calculation compatibility judgment" in the case of building certification application may become a target.
In that case, I add it to each design control charges mentioned above by 0.5% each.
In the case of a construction construction cost to example 1) 20 million yen: Flat 2,100,000 yen
In the case of the construction construction cost to example 2) 20 million yen - 30 million yen: 9.5% of construction construction costs
●The following is not included in the amount of money of the table mentioned above.
1 consumption tax
2 building certification fees
3 special permission application duties expense (takuzokyokasarusei, development permission application)
4 ground investigation expenses
Surveying expense (at a limit as for the surveying to be carried out by a drawing office a winged ant to be performed by 5 surveying experts

●In addition, I match the payment of design control charges with a progress degree of design control duties like the following tables and divide it and ask.
