Quality function of construction process
Strictly implement the project quality plan and construction organization design, and implement the "three presses" construction (that is, according to the design outline, construction organization design and standard construction). Strict process management, so that the process quality is under control, to ensure that the quality of sub-projects is qualified at one time, focusing on the responsibility system, with special emphasis on site management. Control construction progress, organize balanced construction, strengthen information feedback, strengthen construction command and decision-making, and collect engineering data. Carry out quality function activities, clarify the quality responsibility system of all kinds of personnel, organize quality training, establish process quality control points, establish quality information networks, implement quality records and quality evaluation, improve the quality meeting system, and implement process discipline.
(1) Basic methods of construction quality control:
Take the process quality as the purpose, dynamically control the process factors, and act according to the quality responsibility system, and carry out their duties and responsibilities. Conduct qualified engineering activities focusing on prevention once a month, and strengthen the "three inspection system" of working procedures (i.e. self-inspection, mutual inspection and full-time inspection). Grasp the connection and adhesive tape, set up quality management points for key working procedures, and implement key control, such as: set up sample pipe laying and wiring works and sample control box at the beginning of construction, and follow the sample construction in future construction. Strictly abide by the principle of engineering quality first, improve quality awareness, and optimize the construction period on the premise of ensuring quality.
(2) Key points of construction quality control:
In the process of engineering construction, the project department adheres to the principle of total quality management, so that quality management goes deep into the whole process and all staff participate in quality management. In the process of construction, strengthen quality control, quality inspectors and competent engineers are responsible for quality inspection to overcome common quality problems. Our specific methods are as follows:
Pay attention to two key points: laying pipes, grooves and wires to ensure that the laying of wires meets the requirements of design drawings and the insulation resistance of wires to ground meets the design requirements; Pay attention to the equipment installation and debugging of the system, and require its functions to meet the contract and design requirements.
Grasp three stages: namely, grasp the construction preparation stage: organize the preparation of construction organization plan, construction budget, preparation of construction progress plan, countersigning of construction drawing design, construction site investigation, manpower deployment, technical disclosure before equipment, materials and tools enter the site, and safety production training for construction personnel. Grasp the construction stage: inspect the raw materials, semi-finished products and finished products entering the site to check whether the installation and construction quality meets the specification requirements; Grasp the finished product acceptance stage: pass the completion and systematic inspection and evaluation.
There are four means, namely inspection, measurement, test and mandatory documents.
(3) the project quality management system:
Weak current system engineering has strict requirements on engineering quality. If there are quality problems in construction, it will cause irreparable losses. We strictly carry out quality sampling and quality supervision in construction management, and deal with quality problems in time.
Each system must pass the technical index test of each stage, and only after it is completely qualified can it enter the next stage of comprehensive system construction. After all systems are fully constructed, some long, curved or typical system combinations shall be sampled and tested. The initial sampling rate of the project is generally not less than 10%, and generally not less than 5%. The construction administrator at the sampling inspection site is responsible for filling in and filing relevant information.
Quality supervision is the responsibility of the construction team, project department and supervision team. The responsibility of the construction team requires each construction worker to carry out the construction according to the operation specifications. In addition to completing the sampling inspection, the site administrator of the project department should also check whether the management work and actual operation at all construction levels are carried out as required. The supervision team regularly checks the work of the construction team and the site construction administrator, and makes decisions on quality accidents. The quality inspector implements a perfect quality supervision system, and educates, criticizes, punishes and reworks irresponsible construction personnel, and even dismisses them in severe cases. It is required to take remedial measures in time to ensure that the project is completed on time, with good quality and quantity.
When there are quality problems and quality accidents, the site construction administrator will inform similar subsystems to suspend construction, and the site construction administrator and the construction team leader will further verify and find out the reasons for the quality problems. After finding out the reason, the construction team and the construction administrator put forward the solution together. When the reason is unknown, the construction administrator shall report to the engineering department in time, and the engineering department will organize relevant technicians to conduct technical analysis on site until the reason is found out. After the quality problems are identified, the project department will issue a notice to resume work: if economic losses are caused by quality accidents, the construction team will also fill in the accident report, and the project department and the supervision team will make a decision on handling the accidents.
