About the process of interim inspection

Last Updated June 7, 2024

Intermediate inspection is performed when the total area of one building (design building) to be applied for confirmation is 50 m2 or more. The method of calculating the interim inspection fee is on the page of calculating the interim inspection fee.

Interim inspection process schedule
		RC construction	Structure	SRC construction
1st intermediate inspection process		When foundational reinforcement is completed	When foundational reinforcement is completed	When foundational reinforcement is completed
2nd intermediate inspection process		When the second floor slabs are completed from the bottom floor	When jointing of the frame is completed	When the second floor slabs are completed from the bottom floor
In the case of divisional division	1st intermediate inspection process	When foundational reinforcement is completed	When foundational reinforcement is completed	When foundational reinforcement is completed
In the case of divisional division	2nd intermediate inspection process	When the second floor slabs are completed from the bottom floor	When jointing of the frame is completed	When the second floor slabs are completed from the bottom floor

For buildings to which the provisions of Article 7-3, Paragraph 1, Item 1 of the Building Standards Act are applied (for apartments with RC buildings and SRC buildings with 3 or more floors (all those including apartment houses) It will be the implementation process.

Interim inspection period ： When the first foundational reinforcement is completed

□Precautions for basic muscle reinforcement inspection If there are some pits, etc., and you want to launch in advance, please consult with the application for intermediate inspection in advance. If you want to cast a pressure-resistant plate in advance If all beam reinforcements have been completed, an inspection will be performed before casting the pressure-resistant concrete is cast. If the beam reinforcement cannot be completed until after casting the pressure-resistant version of the concrete, consult with the applicant for the intermediate inspection in advance. As a general rule, even if all reinforcements have not been completed, an inspection will be performed before casting (the state where the lower end of the beam is visible).
