In order to strengthen the quality management of highway mechanical and electrical engineering, standardize the inspection and evaluation of construction quality of highway mechanical and electrical engineering, unify engineering quality inspection and evaluation standards, and ensure engineering quality, this standard is formulated. 1.0.2 This standard is applicable to the inspection and evaluation of the construction quality of mechanical and electrical engineering for new construction, renovation, and expansion of various levels of highways. 1.0.3 The sampling inspection frequency of each sub project of highway mechanical and electrical engineering should meet the following requirements: the construction unit's self inspection is 100%; The sampling inspection by the supervising unit shall not be less than 30%; The delivery quality inspection by the testing unit shall not be less than 30%, and the completion quality appraisal shall not be less than 10%. The number of measurement points should not be less than 3. When the number of measurement points is less than 3, all should be checked. 1.0.4 For mechanical and electrical engineering projects in special regions or adopting new products, technologies, and processes, when there is a lack of appropriate quality inspection standards in this standard, relevant technical standards, design documents, or corresponding quality inspection standards can be formulated based on actual situations, and submitted to the competent department for approval. 1.0.5 The quality inspection and evaluation of highway electromechanical engineering should not only comply with the provisions of this standard, but also comply with the current relevant national and industry standards
Function of testing report:
