Equipment Supervision Theory
Domain 2 - Equipment Supervision Theory
This domain tests the institutional skeleton of 设备监理: who supervises whom, under what authority, with which documents and methods, and where the supervisor's liability stops. Questions are situational - a scenario describes a project arrangement and asks which document, which approval, or which intervention is correct.
Core rules
- Definition. 设备监理 is a professional service in which a qualified supervision entity (监理单位), commissioned by the project owner (委托人), supervises the equipment formation process - design, manufacture, inspection, installation and commissioning - against laws, technical standards and the contract. Its authority derives from the contract, not from administrative power.
- Three-party structure. 委托人 - 监理单位 - 被监理单位 (contractor or manufacturer). The supervision entity must have no subordinate or material-interest relationship with the party it supervises.
- Liability boundary. Supervision does not transfer the contractor's quality responsibility. A signed record proves the supervisor was present and the item matched specification; it does not make the supervisor the manufacturer.
- Document hierarchy. 监理大纲 (bid stage, approved by the entity's technical director) → 监理规划 (prepared under the chief supervision engineer 总监理工程师, approved by the entity's technical director) → 监理实施细则 (prepared by the discipline supervision engineer, approved by the chief supervision engineer).
- Hold and witness points. 停工待检点 (H): work may not proceed without the supervisor present. 见证点 (W): the contractor notifies; if the supervisor does not attend, work may continue. 文件见证点 (R): document review only.
- Methods. 巡视, 旁站 (continuous attendance at critical operations), 平行检验 (independent parallel testing), 见证取样, written instructions and meetings.
Worked example
A manufacturer schedules the hydrostatic test of a pressure vessel on a Saturday and asks whether the supervisor "needs to be there". Reasoning: the test is irreversible, safety-critical, becomes invisible once the vessel is painted and shipped, and produces a record that cannot be reconstructed later. Those four characteristics define an H point, not a W point. Correct action: confirm the test procedure, require formal notice with the test package, attend, check gauge calibration validity, and sign only after hold time and pressure are met.
Traps that cost marks
- Swapping W and H logic, or treating 旁站 as a substitute for 平行检验.
- Naming the wrong approver for 监理规划 or 监理实施细则.
- Assuming supervision removes the contractor's liability, or that a supervisor may issue design changes directly.
- Forgetting that H points must be agreed in the inspection plan before manufacture, not negotiated at the machine.
