The main objective of this project includes: 1、implement a project inspection system executed by environmental protection facilities,2、hold seminars and training course on the quality improving and experiment sharing of the construction,3、develop inspection system of engineering quality standard procedures for environmental protection facility,4、establish the ISO 9001 system for the quality inspection the of environmental construction, 5、provide necessary suggestion for improvement in construction quality and innovation ,and 6、manage the Web system for the quality control of environmental construction for Ministry of Environment . The statistical analysis of checking the grades found that the proportion of Grade A in 2023 was 76.9%, and the average score was 81. Compared with the proportion of Grade A in 2022, which was 80.4%, and the average score was 81, the proportion of Grade A dropped slightly. It is speculated that the possible reason is that there were 11 cases of Grade B in 2023 , and they are all projects with a project value of less than 50 million. There are 36 projects with a project value of less than 50 million, 11 of which are Class B. This section is a small and medium-sized project with the largest number of manufacturers and the most diverse types of projects. There are new buildings (improvements) ) projects, landfill projects, resource recovery storage site projects, public toilet projects, indoor hall renovation projects, etc. There are many types of projects and construction companies are prone to encounter those who are inexperienced or even those who are exposed to the project for the first time, so the quality is also It is relatively unstable, so the probability of missing will increase. In 2022, there were 9 B-level projects, 28 projects with a project amount of less than 50 million, and only 6 B-level projects. Therefore, the number of small and medium-sized project cases will indirectly affect the A-level projects in that year. The ratio is the same. Due to the above reasons, the proportion of first-class students in 2023 is also lower than that in 2022. In addition to the above reasons, the scale of project audit amounts also partially affects the performance. A total of 46 project cases were audited in 2022, of which the largest number were projects with a value of more than 50 million, accounting for 39%, and the least was small projects with a value of less than 10 million, with a proportion of 39%. 26%. A total of 40 construction cases have been inspected in 2023 , with the largest number being small projects of less than 10 million, accounting for 40.4%, and the least amount of projects involving more than 50 million, accounting for 23.4%. The proportion of inspections in the past two years is just the opposite. It is speculated that the national Policies promote different subsidy types every year. There are relatively many small and medium-sized project cases this year, especially in the public toilet reconstruction type, which may also affect the ranking relationship. Therefore, the type of project inspections each year may affect the number of inspections with different amounts due to different national policy subsidy types. The analysis of common document deficiencies during the inspection can be roughly classified as follows: the quality plan content of the contractor [4.03.02.04] does not specify the quality management standards for each sub-project and [4.03.04.01] the inspection standards of the independent quality control checklist do not specify the quantification and tolerance The error values are most missing. 28 out of 40 items inspected have the above defects, accounting for 70% of the total. It is obvious that contractors generally do not pay attention to quality plan writing and quality control self-checklists and become mere formalities. They should be inspected according to actual conditions. The situation is quantified and filled in the self-inspection form. The analysis of common document deficiencies during the inspection can be roughly classified as follows: the contractor's [4.03.04.01] Quality Control Self-Checklist inspection standards are not quantified, the allowable error value is missing, and the [4.03.04.02] Quality Control Self-Checklist does not accurately record the inspection values At most, 32 out of 47 inspections had the above-mentioned deficiencies, accounting for 68% of the total. It is obvious that contractors generally do not pay attention to quality plan writing and quality control independent inspection forms and become mere formalities. They should be filled in quantitatively based on the actual inspection situation. Independent inspection form; in terms of project construction quality, [5.09.08] has the most no project notice boards or the content does not meet the regulations. As many as 38 of the 47 inspections have defects related to the project notice boards, accounting for 80.8% of the total, which is currently relatively high. Common deficiencies include errors or omissions in the content of the project notice board, phone numbers, etc. On July 17, 2023, the project committee revised the "Key Points for Setting Up the Project Notice Board and Completion Nameplate" and modified the format of some of the content on the project notice board. Because most of the The manufacturer did not pay attention to the update, so this defect occurred more frequently. During subsequent inspections, staff continued to go to the site to promote the project during the project inspection.
