⑶Work Guarantee

In order to achieve quality goals, quality management plans to carry out actual quality control operations from the following aspects.

①Quality assurance measures in the construction preparation stage

Sound the organizational structure of the project department, select people with high level, rich experience and excellent performance as the main technical personnel, and arrange various projects with A professional team with professional qualifications undertakes the construction.

Implement a certificate-based employment system for construction management personnel and special types of workers to ensure that the quality of personnel meets the needs of project quality objectives.

Be fully familiar with the project bidding documents and construction technical specifications, prepare the project progress plan and implementation construction organization design, and submit it to the owner and supervising engineer for approval before implementation.

The project management department organizes relevant personnel to conduct joint review of drawings. Prepare construction guidance documents. Determine the quality characteristics of the project that should be used, select the corresponding equipment, equip with necessary test instruments, and conduct verification. Conduct necessary testing and verification of new materials and new processes.

②Process technology and construction methods

Develop process quality control documents and conduct proficiency verification for key processes. Develop inspection plans and inspection guidance.

Develop reasonable plans for raw materials, structures, accessories, material consumption quotas, and working hours quotas.

Check whether there are hidden dangers in each construction machinery and equipment, whether the technical performance is good, and whether all test instruments and meters maintain normal sensitivity and accuracy.

Engineering raw materials, prefabricated components, and semi-finished products are ordered, purchased, packaged and transported in strict accordance with quality standards. The construction site laboratory carefully tests the samples taken for market survey and issues approval procedures that meet the requirements of technical specifications before the materials can enter the site. Conduct inspection and acceptance strictly in accordance with technical acceptance standards. If the acceptance personnel find that the quality of the materials has deteriorated or that the incoming materials do not match the samples during the process of entering the site, they should refuse to sign for it, and quickly ask the project quality inspection engineer to inspect and report to the chief engineer and purchaser. Storage, storage and processing shall be carried out in strict accordance with the prescribed conditions and requirements. Keep detailed original records of raw materials entering the site.

③Quality assurance measures during the construction stage

Construction technical documentation must be provided for each process of construction. Construction sketches, steel bar tables, iron parts processing orders, etc. must be reviewed and corrected before being issued. Also pay attention to the collection and organization of internal business information (visas, changes, inspection records, various forms, etc.). This is to facilitate the simultaneous completion of document arrangement work after the project is completed. Construction leaders at all levels personally focus on construction quality and technical briefing workpieces. Actively organize employees to learn relevant quality work procedures to ensure work quality.

Implement the quality model system and the three inspection system. Adhere to the concrete opening application system. During the construction process, comprehensive quality management is implemented, construction quality assurance measures are strictly implemented, original construction records and quality assessment data are carefully sorted and filed, and quality responsibility tracking files are improved.

During the construction process, construction management personnel must conduct inspections and guide construction at any time, formulate process procedures, determine key processes and key points of special processes, conduct continuous monitoring, compare and analyze quality deviations, and correct quality problems in a timely manner. Eliminate quality hazards during the construction process.

After the completion of each process, quality inspections and evaluations must be organized in a timely manner and process handovers must be carried out. If the quality of the previous process is unqualified, the next process shall not be started. During the handover process, the on-site inspector will conduct self-inspection according to the design drawings and technical specifications. After passing the self-inspection, the quality inspection engineer will sign and submit the inspection form to the project chief engineer. After the project chief engineer re-examines and signs the inspection form, the inspection form will be submitted to the supervisor. Engineer review. The quality inspection block diagram and the intermediate inspection procedures for individual projects are as follows:

Strengthen process control during the construction process, strengthen internal quality inspection work, strictly control the quality of each construction process, and ensure that the quality of the project is excellent at the first time. Strictly carry out frequent inspections during the construction process, full-time inspections during process connection, project quality assessment and regular project quality inspections.

A. On-site quality inspectors must follow the work. Key parts of the project and projects approved by the supervising engineer for "three-shift" construction must have quality inspectors waiting on site.

B. After each process is completed, clean the construction site to avoid residues that will affect the quality of the next process.

C. For continuous construction processes, the quality workers at the shift handover site will give detailed explanations to the successors on the construction quality conditions and precautions of the shift, and carefully fill in the shift handover records.

Quality inspection and quality assessment are based on the "Highway Engineering Quality Inspection and Assessment Standards" and let data speak for themselves. Each construction site should simplify the quality assessment standards into easy-to-understand and easy-to-remember oral formulas for different construction projects, and set them up on the construction site in the form of placards so that each construction worker can be familiar with them and facilitate their mastery and application.

Quality assurance control flow chart

Do a good job in branch project assessment.

Each process must be self-inspected first, and then inspected and accepted by the company's quality inspection personnel before the next process can be constructed. Concealed projects must be notified in advance to the supervisory engineer for inspection and approval before construction can begin.

Collect internal industry data, conduct quality self-inspection and assessment of each process, sub-item, division and unit project according to the "Highway Engineering Quality Inspection and Assessment Standards", and prepare according to the completion document preparation method .
