Principles and procedures for quality inspection and evaluation of water conservancy and hydropower projects

Water conservancy and hydropower engineering quality inspection and evaluation should be divided into the project, the project is divided into unit engineering, division of engineering, unit ( process ) engineering and other three levels.

In the project of permanent housing ( management facilities ), special roads, special railway and other engineering projects, according to the relevant industry standards and determine the name of the project.

Principle of project division

Water conservancy and hydropower project division should be combined with the engineering structure characteristics, construction deployment and construction contract requirements, division results should be conducive to ensure the construction quality and construction quality management.

Division principle of unit project

1, hub project, generally to each independent building as a unit project. When the project scale is large, can be part of a building with independent construction conditions is divided into a unit project.

2, embankment project, according to the tender blocks or engineering structure is divided into unit project. Larger cross-linked buildings and management facilities are built on a single unit of work per separate building.

3, water diversion ( channel ) project, according to the bidding blocks or project structure division unit project. Large and medium-sized water diversion ( channel ) buildings to each independent building as a unit project.

4, in addition to the risk of reinforcement project, according to the tender blocks or reinforcement content, and combined with the engineering quantity division unit project.

Division principle of division project

1, hinge engineering, civil engineering according to the design of the main components. Metal structure and hoist installation engineering and mechanical and electrical equipment installation engineering according to the combination of functions.

2, embankment project, according to the length or function.

3, water diversion ( channel ) in the project of the river ( channel ) according to the construction deployment or length division. Large and medium-sized buildings according to the main components of the project structure.

4, in addition to the risk of reinforcement project, according to the reinforcement content or parts.

5, the same unit of engineering, each division of engineering quantity ( or investment ) should not be too big, each unit of engineering division of engineering number, should not be less than 5.

Division principle of unit engineering project

1, according to the water conservancy and hydropower engineering unit engineering construction quality acceptance evaluation standard ( sl 631 ~ sl 637 - 2012, sl 638 ~ sl 639 - 2013 ) provisions are divided.

2, river ( canal ) road excavation, filling and lining unit engineering division boundary should be located in deformation joints or structural joints, length is generally not more than 100 m.. The quantities ( or investment ) of each unit project in the same branch project should not differ too much.

3, " unit engineering evaluation standard" does not involve the unit project can be based on the engineering structure, construction deployment or quality assessment requirements, according to the layer, block, section.

Project partitioning program

1, by the project legal person organization supervision, design and construction units for engineering project division, and determine the main unit project, the main division of the project before the start of the project division table and instructions written report to the corresponding engineering quality supervision institutions for confirmation.

2, engineering quality supervision institutions after receiving the project division of a written report, should be within 14 working days to confirm the project division and confirm the results of the written notice to the project legal person.

3, in the process of project implementation, need to adjust the unit project, the main division of engineering, important hidden unit engineering and key parts of the unit project division, project legal person should be re submitted to the engineering quality supervision institutions to confirm.
