(2) The item and standard of appearance quality evaluation shall meet the provisions in Annex A of this standard; the scoring average of appearance quality evaluation shall reach 85% or more;
(3) The quality assurance information shall be complete.
2.2.4 If the sub-divisional work quality do not meet the qualification provisions in corresponding quality inspection and evaluation standard, the sub-divisional work shall be handled in time and determined the quality level according to the following provisions:
2.2.4.1 The rework one may evaluated the quality grade over again.
2.2.4.2 For the one reach the design requirements after repairing, the quality is qualified.
2.3 Procedure and organization
2.3.1 The partitioned project leader organize the evaluation of the sub-divisional work quality on the basis of team self checking and the full-time quality inspector check and ratify the sub-divisional work quality. The standard format of quality inspection and evaluation table of subentry project shall meet in Annex B of this standard.
2.3.2 The unit project leader organize the evaluation for partitioned project and the full time quality inspector check and ratify the partitioned project quality. The contents and format of quality assurance information check table the requirements in Annex C of this standard. The format of overall evaluation table of partitioned project quality shall meet the requirements in Annex D of this standard.
2.3.3 The general contract organization shall be fully responsible for the engineering quality. When the partitioned project is subcontracted and constructed by several organizations, each subcontractor shall inspect and evaluate the quality level of constructed sub-divisional work according to the requirements in this standard and submit the result and information of evaluation to general contract organization.
2.3.4 The inspection tools adopted in inspection method of this standard shall meet the provisions in Annex E of this standard.
