The end of the covert project, I believe many owners are relieved, but it is still too early to relax, wait until the acceptance of the hidden project is considered a real clearance, if the acceptance is not good, many hidden problems in the future will bring a lot of trouble Not to mention that rework is still very troublesome and a waste of money. Therefore, it is very important that concealment projects do a good job of acceptance. First of all, what we must understand is that what are the items of hidden project acceptance?
First, procedures for acceptance of concealed works
1, the acceptance process
The contractor has completed the self-examination of the concealed project → the acceptance of the concealed project acceptance → the notification of the supervision/party inspection → the relevant test before concealment → the test is qualified (the unqualified return to the previous step) → the processing of the concealed construction qualified visa → concealment → completion.

If the project has hidden conditions or meets the agreed acceptance clause, the contractor shall carry out self-inspection against the construction design and construction specifications, and notify the engineer in written form 48 hours before the concealment or intermediate acceptance. The notice includes covert and intermediate acceptance contents, acceptance time and place.
3, joint inspection
Hidden project acceptance should be organized by the supervision engineer. After receiving the contractor’s request for acceptance inspection, the contractor shall organize the relevant personnel and the contractor to jointly inspect or test at the agreed time. The test result indicates that the quality has passed the acceptance. After the engineer signs the acceptance record, the contractor can carry out the project concealment and continue construction. If the acceptance fails, the contractor shall modify it and re-accept it within the time limited by the engineer.
4, re-inspection
Regardless of whether the engineer has participated in the inspection and acceptance, when he has doubts about the quality of a certain part of the project, the contractor may be required to re-inspect. After receiving the notice, the contractor shall peel or open the hole as required and re-cover or repair it after inspection.
