What is the legal basis of the project warranty period in Shaanxi Province?

1. What is the legal basis for the project warranty period in Shaanxi Province? Article 40 of the State Council's Regulations on Quality Management of Construction Projects stipulates that the minimum warranty period of construction projects is 1 under normal use conditions. The reasonable service life of infrastructure projects, housing foundation projects and main structure projects as stipulated in the design documents; 2, roofing waterproof project, bathroom, room and exterior wall waterproof requirements, for 5 years; 3. The heating and cooling system consists of two heating periods and cooling periods; 4, electrical pipes, water supply and drainage pipes, equipment installation and decoration engineering for 2 years; 5. The warranty period of other projects shall be agreed by the construction unit and the construction unit in the contract. The warranty period of the construction project shall be calculated from the date when the project is completed and accepted. Second, how to ensure the engineering quality? 1. Scientific management, establishing and perfecting various management systems, and formulating post responsibility system and various rules and regulations are the primary tasks and important components of enterprise management. The project manager must attach importance to the establishment of the system, especially to the supervision and implementation of the work on the construction site. On the basis of the original rules and regulations, according to the actual situation on site, the post responsibility system of all kinds of personnel is established, and the responsibilities of the on-site management personnel are clearly defined, and posted in the on-site office in written form for reference. At the same time, the operation and maintenance system of various machines and tools, electricity consumption, tic-tac-toe frame, external wall scaffolding and other equipment shall be defined and managed by special personnel to ensure that all work is in place. Responsibility is carried out on the project of "Suifu Primary School": According to the actual situation of the construction site, the project department has established the dispatching meeting, analysis meeting, disclosure meeting, inspection and assessment system, and established the data filing system. Strengthen the plan management, revise the plan in time according to the overall schedule requirements and the actual construction, realize the control of important nodes, and make the plan management in the best state. The establishment of the construction site briefing system, timely notification of the project situation to all parties, and the establishment of a summary system have greatly strengthened the on-site construction management and won unanimous praise from all parties. 2. Raise awareness and strengthen the management of front-line workers. To improve the level of construction management, we must be ahead of the times, that is, we must first raise management awareness. The core problem of an enterprise is management. Due to the great mobility of production workers, poor general technical quality and weak quality awareness, they only pay attention to the progress of work, ignore the scale and quality of the project, covet convenience, blindly seek for speed, have a weak sense of responsibility and poor safety awareness, and construction management is very difficult. These awareness and practices should be completely changed. On the basis of improving managers' awareness, the project manager should also strengthen the management of production workers. The specific approach is to implement the principle of "one selection, two teaching and three management". The first choice is to implement the principle of "survival of the fittest" for production workers, and those production workers with poor safety awareness, low technical quality and disobedience to management must be eliminated. Second, education is not only the "three-level education" for workers before taking up their posts, but also the safety technical disclosure and safety technical visa before entering the site. It is necessary to implement a clear reward and punishment system for the workers in each construction team in order to fully mobilize the enthusiasm of the workers and give play to their leading role. Pre-job training should also be given to the operators in the main parts of each type of work and project. The "Three Pipes" means to make technical disclosure to production workers before construction, strictly control each working procedure during construction, track, supervise, record, audit or spot check, and strictly control the quality from technical measures to actual operation. Adhere to the combination of self-inspection, mutual inspection and sampling inspection; Adhere to the specific practice that the previous process is unqualified and does not flow into the next process, especially for the types of work and processes prone to common quality defects, implement full follow-up construction, constrain common quality defects by compulsory means, and change irregular practices. 3. Organize the construction, and strive to do a good job in project quality and safety management. When directing various projects, the project manager must conscientiously do a good job in project quality and safety management, and organize multiple units to carry out construction in a rhythmic and balanced way at a construction site in order to achieve the effect of short construction period, good quality, safety and low cost. This is a very complicated problem, including technology, quality, safety, materials, progress, construction site and other management work. Therefore, in the construction management, it is necessary to implement institutionalization and networking, straighten out the company's management system, and institutionalize various management. The project manager should often organize professional business analysis meetings to reflect the conclusions and information of various professional business analysis to the company in time, so as to better realize the comprehensive control of the on-site construction process. In project management, we should strictly follow the "three inspections, two persistence and one excellence" (i.e. self-inspection, mutual inspection and re-inspection; Adhere to the construction according to the drawings and specifications; High-quality goods) policy for construction, do listing construction, responsibility to people, ideas in place. Quality management should overcome common faults, create excellence and improve quality, eliminate potential quality hazards in the bud of the construction process, check and accept every working procedure, and improve the first-time qualification rate of products. Strive for the excellent rate of the project to reach more than 80%. Efforts should be made to overcome and eliminate common diseases such as "seepage, leakage, shell, crack, fall, roughness, blockage and pollution" in the project, improve the project quality with management system and ensure the project quality with technical measures. In terms of safety management, it is necessary to strengthen safety education, strengthen safety education, and improve the safety awareness of workers and migrant workers. The company should be willing to spend manpower, material resources and financial resources to do a good job in safety facilities, and the construction management personnel should be conscientious. In the construction of Suifu Primary School, the education and protection of "Three Treasures and Four Doors" were particularly strengthened, and the practice that gantry and scaffolding can only be delivered after sectional acceptance was supported. Organize a voluntary fire brigade under the direct command of the project manager. Safety warning signs and safety slogans can be seen everywhere in the construction site, aiming at safety mobilization and safety production. In fact, to put it bluntly, the warranty period in Shaanxi Province is consistent with the national construction project management regulations. The warranty period for the completion of construction projects in Shaanxi Province has clear requirements according to different sub-projects. General engineering warranty period must also meet the reasonable service life of the original design documents, but countries such as waterproof engineering and installation engineering have clear time regulations.
