  Table 2 of the construction quality, Table 4 has obvious problems, Ks<0.6, the technical quality of the formal design scheme has serious defects, can not meet the design task book or contract requirements, Kj <0.6, or important indicators can not meet the relevant standards; The information is incomplete, not standardized, there is an error in the actual project, Kz<0.6, it is judged as not passing; or one of Ks, Kj, kz is less than 0.6; or key items (see Table 5, the number in the upper right corner is *) If the inspection result is unqualified, it is judged as not passing.

 

  7.2.4 Make recommendations and requirements

 

  The acceptance team (acceptance committee), when making the acceptance conclusion, makes recommendations and requirements for the main problems in the acceptance, and fills in Table 7.

 

  7.3 The system that fails to pass the acceptance shall not be delivered for use. The design and construction unit shall, according to the problems raised by the acceptance conclusion, promptly implement the rectification and then carry out the acceptance; when the system is retested, the sampling proportion of the original non-passing part shall be appropriately increased.

 

  7.4 After the acceptance meeting is over, the complete set of acceptance drawings and materials shall be returned to the design and construction unit in time.

 

  7.5 After acceptance or basic approval, the design and construction shall be written by the unit according to the acceptance conclusion and approved by the construction unit.

 

  8 system handover

 

  8.1 System Completion Drawing Data Revision and Filing

 

  After acceptance or basic approval, the design and construction unit shall organize and compile the system completion drawings and materials in accordance with the following requirements, in triplicate construction units. After the construction unit signs and seals, one of them shall be returned to the design and construction archive.

 

  8.1.1 Provide revised, proofreading and conform to the acceptance drawings specified in 4.7.

 

  8.1.2 Acceptance conclusions (including the list of members of the acceptance agency).

 

  8.1.3 Design, implementation measures of the construction unit according to the acceptance conclusion and approved by the construction unit.

 

  8.1.4 Design, the construction unit provides instructions for the daily maintenance and system operation of the equipment.

 

  8.2 After the system acceptance has passed or passed basically and there are rectification and implementation measures, it can be formally transferred and put into use. The construction unit or the user unit should have a special person responsible for it, and establish a system operation, maintenance, management and other systems; system design, construction unit should be established and implemented Maintenance service system.

 

  8.3 Registration procedures

 

  The design and construction unit shall submit a copy of the complete set of completed drawings and materials compiled and prepared to the public security technical defense management department for completion registration in accordance with the requirements of 8.1.

 

  8.4 Involving the drawings and materials above the confidentiality, the construction unit, design, construction unit and related units and their personnel must abide by the relevant national confidentiality regulations and control the secret surface to a minimum extent.
