In the case of wall attachments other than those in the manual, the construction unit or rental unit shall entrust the original manufacturing unit or professional manufacturing unit to carry out special design and manufacture of the attached structure. The design document is used as an attachment to the special construction plan of the installation and disassembly project. When the construction general contractor organizes the demonstration of the special plan, it only demonstrates the content of the construction plan for the installation and disassembly of the lifting machinery.
After the attachment structure of the entrusted special design is manufactured, it shall be inspected and passed the factory according to the special equipment manufacturing regulations, and its manufacturing and delivery inspection certificate shall be listed as one of the documents submitted for entrusted attachment inspection.
2. Reinforce the responsibilities of all parties and strengthen the management of assembly and disassembly operations
(1) The management and control requirements of the general construction contractor. Before the implementation of the special plan, the construction general contractor shall organize the plan according to the regulations; before each installation or disassembly operation, the operators of the assembly and disassembly unit shall be registered and the safety technical report shall be signed and confirmed by both parties.
During each assembly and disassembly operation, the construction general contractor should arrange a full-time safety officer to supervise the process, check the implementation of the plan, and truthfully record the supervision records. Violations and potential safety hazards should be corrected and stopped in time to ensure the safety of assembly and disassembly operations.
(2) Management and control requirements for installation and disassembly units. When the operator of the installation unit enters the site (including each attachment jacking), they must first inform the construction general contractor, and only after the construction general contractor has registered and confirmed and the safety technology clarifies, can they enter the assembly and disassembly operation site. Before installation and disassembly (including each attachment jacking), the professional and technical personnel of the installation unit must conduct an inspection, and it is forbidden to install unqualified parts and structural parts.
After the lifting machinery is installed, the installation unit shall organize a self-inspection. For those unqualified due to installation quality reasons, they shall be handed over to relevant departments for processing in accordance with the provision of false self-inspection certificates.
(3) The management and control requirements of the supervision unit. The supervision unit shall compile the detailed supervision rules for the installation and disassembly of construction hoisting machinery in accordance with the regulations, and implement special inspections and side station supervision for the installation and disassembly (including each attachment jacking) construction situation. If violations of regulations and potential safety hazards are found, they shall be ordered to rectify or stop assembly and disassembly, and report to the construction unit in time. If the construction unit and subcontractor refuse to make rectification or stop the assembly and disassembly, they shall promptly report to the construction unit and the local housing and construction department or safety supervision agency.
(4) Testing and inspection requirements of testing units
1. The construction hoisting machinery inspection unit shall establish a hoisting machinery acceptance commission and inspection and testing work flow in accordance with the regulations and relevant regulations. Starting from June 1, 2020, the testing unit should first conduct a data review, and the data can be subject to physical testing only after the data has passed the review. The data review record (see attachment) is uploaded to the smart safety supervision platform of our bureau along with the test results, and the testing unit is responsible for the data review results.
2. The testing unit shall carry out physical testing in strict accordance with the testing procedures and relevant management regulations of our city, and shall bear the testing responsibility if the corresponding testing fails to detect, should be discovered but not found hidden dangers and causes safety accidents. During the inspection, if there is a major safety hazard, it must be reported to the local housing and construction department in time.
3. In line with the principle of convenient service, the testing unit should set up a sampling window nearby, publicize the process and supervise the telephone. Actively develop and construct the inspection system of the unit, realize the completion of the docking with the city's smart safety supervision system as soon as possible, and provide construction and installation units with fast services that can receive electronic inspection reports through the smart safety supervision system.
3. Intensify supervision and spot checks, and tighten the responsibilities of all parties
