The construction quality acceptance is only applied with a quality grade "qualified"; in case of any nonconformity, it shall comply with Article 4.1.12 in this standard. 3.0.3 The engineering quality evaluation shall be conducted for the projects with the "high quality" engineering objective. 3.0.4 The engineering quality evaluation shall be conducted by the three phases (stage) - single project, single unit and overall project. 3.0.5 The construction quality evaluation for single project shall be conducted upon that the construction quality acceptance for all unit projects is qualified and the collection and rearrangement of engineering technical document is completed, and the evaluation shall cover the whole work content before 168-h trial operation with full load. 3.0.6 The quality evaluation for single unit shall be conducted after the construction quality acceptance for all single projects and the 168-h trial operation of the unit with full load are completed and the environmental protection projects supported are normally put into operation. The synergic system shall be bought into the evaluation for the first unit. 3.0.7 The quality evaluation for overall project shall be conducted after the quality evaluation for all single units, the performance tests of the units and the engineering archives evaluation are completed.
