There are 61 key points for acceptance of concealed works, which must be known by construction, Party A and supervisor! Concealed works generally refer to the works that need to be covered and covered, such as foundation, electrical pipeline, water supply and heating pipeline, etc.
➤ axis and setting out of main works (1) (each floor).
After concealed works are concealed, if quality problems occur, they need to be covered and covered again, which will cause great losses such as rework.
The following is a summary of 61 key points related to concealed works acceptance, in place! Acceptance process of concealed works (1) before the commencement of concealed works, the project department shall be responsible for inspecting the materials used.
(5) The project department shall conduct spot check on the concealed works, check the construction records, sign on the concealed works acceptance certificate after confirmation, and report to the engineering supervision department of the supervision company for inspection.
