- Introduction
Core Value and Scope of Application of the Standard
NB/T 11319-2023, as an important industry standard in the field of hydropower engineering construction, has systematically constructed a quality management framework covering the entire life cycle for the first time. The standard is applicable to new, rebuilt and expanded hydropower engineering projects, emphasizing the four basic principles of excellent quality, safety and reliability, reasonable construction period and controllable cost.
Key points of quality management system innovation
Dimension Traditional model Requirements of this standard Responsibility system Segmented division of responsibility Primary responsibility of construction unit + main responsibility of participating units Control node Mainly in the construction stage Survey and design→equipment procurement→construction→commissioning entire process Technical means Mainly in manual inspection Application of informatization + intelligent technology Typical application cases
A large hydropower station project implemented clause 7.3.6 of this standard and implemented on-site supervision of the hydraulic generator set:
- Established 12 key quality control points
- Discovered and dealt with 3 types of material defects
- The equipment acceptance rate reached 100%
Key link control requirements
Survey and design stage
Clause 5.4 clearly states that the design input must include 5 types of basic information:
- Laws, regulations and technical standards
- Surveying and mapping geological and hydrological data
- Equipment technical parameters
- Approval document requirements
- Similar project experience
Construction supervision stage
Clause 6.3.7 innovatively proposes the three-point control method:
- Witness point (point W): witness of key processes
- Stop-work inspection point (point H): mandatory acceptance node
- Onsite station (point S): monitor key areas throughout the process
Suggestions for the implementation of the standard
Organizational guarantee measures
It is recommended that the construction unit establish a three-level quality management network in accordance with Clause 4.2.10:
Decision-making level Project Quality Committee Management level Full-time quality management department Execution level Quality team of participating units Technical Implementation Path
In response to the construction machinery management requirements of Clause 8.4.9, it is recommended to adopt the QR code equipment management system:
- One machine, one code identity authentication
- Automatic reminder of maintenance cycle
- Real-time monitoring of operating status
