The concrete structure is made by erecting formwork in situ and integral casting, hereinafter referred to as cast-in-situ structure.
2.0.3 Precast concrete structure
The concrete structure is made by assembling and connecting the precast concrete members or parts, hereinafter referred to as precast structure.

Inspection items or points of concrete structure construction quality failing to follow the requirements are classified into serious defects and common defects according to the degree.
2.0.5 Serious defect
Defects having dominating influence on the stressing property, durability or installation and service property of structural members.
2.0.6 Common defect
Defects without dominating influence on the stressing property, durability or installation and service property of structural members.
2.0.7 Inspection
Activity in which the features and performances of the inspected item are determined, inspected and tested, and the results are compared with the requirements specified in standards so as to verify the acceptance of each performance.
2.0.8 Inspection lot
The inspection body summarized according to the same production conditions or provisions for the sampling inspection and comprising of certain quantity of samples.
2.0.9 Site acceptance
The process in which the materials, members and accessories, instruments and semi-finished products on the construction site are inspected according to relevant standards and confirmation shall be given to their quality, mainly including appearance inspection, quality certificates inspection and sampling inspection.
2.0.10 Inspection of structural performance
The inspection over the structural members for the indexes of bearing capacity, deflection and crack control performance.
2.0.11 Entitative inspection of structure
The process in which a sample is taken from a structure entity and inspected on site or delivered to the testing body with qualification.
2.0.12 Quality certificate document
Effective documents, in accompany with approaching materials, members and accessories, instrument and semi-finished products, provided to certify the quality.
3 Basic Requirements
3.0.1 Concrete structure, as sub-subsection project, may be classified into subitem projects of formwork, steel bar, prestress, concrete, cast-in-situ structure and precast structure. Each subitem project may be classified into several inspection lots according to approaching lots, shift, storey, structural joint or construction section in the principle of consistence with production and construction mode and being convenient for construction quality control.
3.0.2 The quality acceptance of concrete structure shall cover quality control data inspection, appearance quality acceptance and entitative inspection of structure stipulated in 10.1 provided that the acceptance of subitem projects concerning steel bar, prestress, concrete, cast-in-situ structure and precast structure is eligible.
3.0.3 Quality acceptance of subitem projects shall cover quality acceptance record inspection provided that the acceptance of inspection lots contained is eligible.
3.0.4 Quality acceptance of inspection lot shall cover substance inspection and materials inspection and shall meet the following requirements:
1 The quality of all dominant items shall be subjected to sampling inspection and qualified.
