Example analysis difference

 

Example1Building curtain wall and doors and windows

When the curtain wall (doors and windows) is evaluated as a whole, professional judgment shall be relied on, combined with scheme design, and comprehensive evaluation shall be carried out through on-site observation, test data, documents, etc., which shall be classified as inspection activities.

 

The on-site inspection of building curtain wall (doors and windows) that is only responsible for the test object should be classified as the inspection activity category.

 

Example 2:Biosafety Laboratory Engineering

 

The design rationality evaluation, construction quality monitoring, project quality acceptance and evaluation of biosafety laboratory engineering; the monitoring and evaluation of laboratory performance, operation safety and structural state; those that need to rely on professional judgment for scheme design and comprehensive evaluation through on-site inspection, test data judgment and document review should be classified as inspection activities.

 

Those who are only responsible for the results of a certain parameter measured by the laboratory and provide reference for comprehensive judgment of project quality, identification or evaluation of service performance should be classified as testing activities.
