1. Reason for revision
The aim is to secure national safety by clarifying the roles and responsibilities of structure designers in order to strengthen the safety management of mass plate structures and improve design errors identified as the main cause of missing reinforcing bars and by strengthening the verification of regional architecture committees in accordance with the “Construction Cartel Breakdown Plan” (December 12, 2023) announced by the government due to the Incheon Geomdan accident, etc., and the aim is to improve the safety management efficiency of current buildings through rational system operation by activating seismic reinforcement with the expanded application of architectural standards on floor area ratio, etc. in the seismic reinforcement of current buildings and classified application of the current structural safety identification procedure in consideration of load change levels, etc.
2. Main contents
A. Strengthening the safety management of flat plate structures (Article 2 Item 18 C and Article 19.3 Item 1 C of the Draft)1)
Buildings with floors where flat plate structure pillars support the entire load are classified into special structure buildings to strengthen safety management during design, construction, and supervision.2) In case of basement floors with flat plate structure, supervisors and architectural engineers check the bar placement during construction.
B. Strengthening the expertise in architectural structures of regional building committees (Article 5-5.6.2.J of the Draft)
Structural expertise committees shall be set up in order to conduct structural safety review, etc. through regional architectural committees organized with expert members in the architectural structural area during authentication/permission.
C. Clarification of subjects for the application of eased architectural standards (Article 6.1.6 C)
Errors in the current provisions on the subjects for the easing of floor area ratio for seismic reinforcement of current buildings are corrected, and provisions are clarified for easy understanding.
D. Rationalization of structural safety identification procedure of current buildings (Articles 32.3 and 32.4 of the Draft)1)
As a repair activity necessary for building safety management, exception regulations are established to simplify the structural safety confirmation process for expansion and major repairs that require no changes in the structural part, only minor changes in structural strength.2) The new provision of Article 2.18 (c) of the Draft is reflected to Article 32.2.8 of the Draft, and the “construction” previously defined in the main text of Article 6.1.6 (c) is stated as “extension, partial remodeling” in Article 32.4 of the Draft.
E. Improvement of provisions on the qualification of related expert engineers (Article 91-3.3 of the Draft)1)
Improvement of qualification of related engineers to secure cooperation in soil excavation, etc. within the job range of soil and geology specialization areas prescribed in the current Professional Engineers Act
F. Clarification of the roles and responsibilities of architectural structure engineers for structure design (Article 91.3.8 of the Draft)
The range of cooperation in structure design shall follow the “Design & drawing standards” to clarify the roles and responsibilities of structure engineers for the preparation of structural drawings.
