The construction drawings of the Jitai Dazhi Straight were buried. Land and Resources Department: The competent authority should have supervised the preservation of copies.

Jitai Construction's "Jitai Dazhi" construction project is suspected to have caused the adjacent building to collapse due to improper construction.

Three years have passed since the Ketai Dazhi collapse case, and there has been no progress in house reconstruction. The 25 affected households are dissatisfied and have no homes to return to. The North City Government's Construction and Management Office further stated that the construction drawings were buried during emergency grouting and backfilling on the day of the incident, causing controversy. In this regard, the Department of Land and Resources stated that construction companies should properly prepare construction drawings in accordance with the law for construction management and subsequent inspection. The competent authority should supervise construction companies to implement a copy storage mechanism.

In response to the local government’s claim that the construction drawings on the construction site were not required to be retained by the central government. The Land Management Office of the Ministry of the Interior stated on the 13th that in accordance with Article 26 of the Construction Industry Act, the construction industry contracting project shall prepare on-site construction drawings and be responsible for the construction. Anyone who violates the regulations shall be subject to Article 56 of the same Act and the severity of the case, and the maximum penalty may be suspension of business for less than one year.

The Department of Land and Resources stated that construction manufacturing drawings are important documents for construction management, and construction operators should properly prepare them in accordance with the law for construction management and subsequent inspection. In the process of producing relevant illustration files, it is necessary to go through paperwork processes such as seal approval, printing and output, and copy storage. The competent authority should supervise construction operators to implement a copy storage mechanism on a daily basis.

The Department of Land and Resources pointed out that when a construction site faces a sudden accident, resulting in the loss or damage of on-site construction drawings, etc., it should also proactively provide backup drawings and description files to the competent authority to clarify relevant rights and responsibilities.
