Regarding the three inspections and four confirmations in the construction process
Thread Content
Dear experts, could anyone tell me where I can find the specific standards for the three inspections and four determinations? For example, when I need to inspect pipelines on site, what standards must be met for them to be considered acceptable? Similarly, what standards apply to civil engineering work, and what counts as meeting those standards? . At present, our installation is about to start on-site piping work. Most of the staff are newly graduated employees, and I am preparing some materials to use for their training. I would appreciate any advice you could offer. . . It mainly consists of training materials on the three checks and four determinations, as well as the specific standards for each inspection item. . . . Thank you very much. . .
Arm yourself with knowledge first; I’m not sure what the original poster’s educational background and work experience are.
I just want to learn more :L I’m afraid I might be missing something
First, share what you know about the three checks and one certainty, and then we can discuss it. I don’t know how to do it, so I’m here to learn*.
Check for design omissions, inspect construction quality, and examine unfinished work. The scope of inspection is quite broad; all equipment, pipelines, instruments, and valves must meet the specified requirements and be of satisfactory quality.
Three inspections: check for missing items in the design, inspect the quality of the work and any potential hazards, and examine the amount of work that remains unfinished. Four fixations: For the problems identified, assign tasks, designate personnel, set deadlines, and determine measures to ensure completion within a specified time frame ； Another explanation for the \"four fixings\" is: fixing the personnel, fixing the measures, fixing the time frame, and fixing the funding. As for the detailed \"three inspections and four fixings\": these involve checking for missing items in the design, examining the quality of construction, and reviewing unfinished projects ； Define the process, the planned measures, the operators, and the timeline. Check for design omissions: Conduct a final review of the design and construction drawings based on the actual conditions on site, to determine whether there are any design omissions and if any additional design work or improvements are needed ； Check the construction quality: First, verify whether the installation of process equipment and pipelines is in line with the design drawings, then conduct a comprehensive inspection of the overall appearance quality. Any issues that require correction should be identified in writing and immediate action taken to address them. For the internal inspection of construction quality, it is required to examine the quality certificates of the installation materials and welding materials, the welding procedure qualification reports, the non-destructive testing reports for pipe welds, as well as the reports on the purging and pressure testing of the pipeline system ； Check unfinished projects: Conduct on-site inspections to identify which items are supposed to be completed according to the construction schedule but have not yet been finished. Define the process: A detailed, accurate, and feasible process flow must be established, and every detail must be taken care of during implementation. Formulate plan measures: Based on the process flow diagram, develop a plan that includes each piece of equipment and each pipeline. Designate operators: Determine the organizational structure and operators to ensure unified planning and command. Set a time: Determine the specific date and time.
It is recommended to study the construction and quality inspection specifications for related fields; these specifications provide detailed rules for construction, as well as standards and methods for inspection
It involves regulations regarding design and construction quality; specific issues are analyzed on a case-by-case basis. There are many regulations, and inspections are carried out in accordance with these requirements
It involves many aspects, and no single field of study can handle them all; it is necessary to look into them by specialty. Many things are highly specialized.
