1.0.4 The construction parties concerned shall standardize management system, personnel allocation, site management and process control, and implement construction and management requirements such as quality, safety, construction period, investment returns, environmental protection and technological innovation.
1.0.5 Railway concrete and masonry engineering construction must follow the national laws and regulations and relevant technical standards and the design documents, with raw materials, mix ratio, construction technology, and test and testing being controlled strictly, to meet the requirements of safety, durability and use functions of engineering structure and to ensure normal operation within the design working life.
1.0.6 During railway concrete and masonry engineering construction, efforts shall be put to implement sustainable development strategy of the national economy, make reasonable application of resources, and conduct environmental protection and water and soil conservation measures.
1.0.7 Railway concrete and masonry engineering shall be constructed by modern means, e.g. mechanization, industrialization, specialization and informationization, to ensure engineering quality and construction safety.
1.0.8 Railway concrete and masonry engineering construction shall strictly follow safety procedures and corresponding occupational health standards, for which corresponding safety technical measures shall be established.
1.0.9 Advanced, mature and scientific testing measures are adopted for railway concrete and masonry engineering. Quality testing data must be authentic and reliable, which shall fully reflect the engineering quality condition. The methods and apparatus used shall meet the requirements of relevant standards. Instrument precision shall meet quality control requirements and quality testers must be qualified accordingly.
1.0.10 Various quality testing reports, records on inspection and acceptance and other technical data of railway concrete and masonry engineering must be timely filled in as required and confirmed upon signature of the person responsible.
1.0.11 The requirements for construction quality in the contract agreement and technical document adopted during railway concrete and masonry engineering construction shall not be inferior to those specified in this standard. In the case that designed quality indicators superior to those specified in this standard, the former shall prevail.
1.0.12 Railway concrete and masonry engineering construction and acceptance personnel shall take up their posts only after they pass specialized training.
1.0.13 This standard shall be used with standards for constructional quality acceptance of railway engineering in different specialties.
1.0.14 For the new technologies, process, equipment and materials not involved in this standard, complementary standards shall be developed separately for the acceptance of their constructional quality.
1.0.15 Constructional quality acceptance of railway concrete and masonry engineering shall not only meet the requirements of this standard but also comply with those stipulated in the current relevant standards of the nation.
2 Terminologies
2.0.1 Constructional quality of engineering
All the obvious and implied characteristics in such aspects as safety, functions of use as well as durability and environmental protection, for reflecting that the construction process of engineering or the mass meets those specified in the relevant standards or contract.
2.0.2 Acceptance
The concerned organizations involved in the construction activities jointly conduct the inspection for the quality of inspection lot, subitem, subsection and unit engineering on the base of the self-inspection on the constructional quality of engineering conducted by the construction organization and make a writing confirmation the quantity conformity condition of engineering in accordance with the relevant standards.
