How to strengthen construction management in floor construction to ensure the smooth progress of the construction process?

🎊  Construction preparation stage

🎨  Technical preparation: Organize technical personnel to be familiar with the construction drawings, master the floor design requirements, technical standards and construction technology. Prepare a detailed floor construction plan, covering the construction process, quality standards, safety measures, progress plan, etc., and submit it to the supervision and construction unit for review and approval. At the same time, conduct a comprehensive technical briefing for the construction personnel to make them clear about the construction process, quality requirements and safety precautions.

🎨  Material preparation: According to the construction drawings and plans, accurately determine the variety, specifications, and quantity of the required floor materials and purchase them. Strictly inspect the purchased floor materials, check whether the quality certification documents and specifications are consistent, and strictly prohibit unqualified materials from entering the site. According to the material storage requirements, keep them properly to prevent moisture, deterioration, and damage.

🎨  Staff preparation: Establish a professional floor construction team, and the construction personnel should have the corresponding skills and experience, and be qualified after training. Clarify the job responsibilities of each construction personnel, and make sure that the division of labor is clear and the responsibility is assigned to the person. Provide safety education and training for construction personnel to improve safety awareness and self-protection ability.

🎨  Equipment and tool preparation: According to construction needs, equip with complete floor construction equipment and tools, such as concrete laser leveling machine, floor grinder, vacuum cleaner, mixer, trowel, etc., and ensure that the equipment is in good performance and can operate normally. Regularly inspect, maintain and service the construction equipment and tools, and replace damaged parts in time to ensure safety and reliability. For the concrete laser leveling machine, you must be familiar with its performance and operation methods, debug it before use, and ensure that the laser system, hydraulic system, etc. work normally.

🎨  Site preparation: Clean the construction site, remove obstacles, level the site, and ensure that the construction site is solid and flat. Take drainage measures at the construction site to prevent water accumulation from affecting the quality of floor construction. Set up obvious construction signs and warning signs, demarcate the construction area, implement closed management, and prevent unrelated personnel from entering.

🎊  Construction process management

🎨  Base treatment: Clean the surface of the base, remove debris, dust, oil, etc., to ensure that the surface of the base is clean, flat, and crack-free. Check and accept the base, the flatness deviation should meet the design requirements, and the non-compliant parts should be processed. According to the conditions of the base layer, take appropriate treatment measures, such as applying interface agent, repairing cracks, etc., to enhance the bonding force between the base layer and the floor.

🎨  Floor material laying: Lay the floor material according to the construction plan and material instructions, pay attention to the uniformity and density of the material, and avoid defects such as hollowing and cracks. Control the laying thickness of the floor material to ensure that it meets the design requirements and the deviation is within the allowable range. If it exceeds, make corrections. During the laying of the floor material, vibrate and compact it in time to remove air so that the material is closely combined with the base layer. If a concrete laser leveler is used, after pouring the concrete, use it for rapid leveling to improve the flatness and density.

🎨  Floor construction process control: According to the flatness of the floor, reasonably select grinding equipment and grinding discs for floor grinding, control the grinding speed and pressure, and ensure that the surface is flat and smooth. After grinding, vacuum and clean in time. Mix the materials according to the requirements of the floor material mix ratio to ensure uniform mixing and consistent performance. After the mixed floor material is laid, smooth it in time and control the speed and angle of the smoothing machine. When using a concrete laser leveler, it is necessary to operate it in accordance with its operating procedures to ensure that the laser system accurately controls the elevation of the leveling head and achieves high-precision leveling.

🎨  Construction quality control: Establish a quality management system, clarify the responsibilities of quality management personnel, and strengthen quality control during the construction process. Strictly follow the construction specifications and quality standards for construction, conduct quality self-inspection after each process is completed, and report to the supervision unit and the construction unit for acceptance after passing the inspection. For quality problems that arise during construction, promptly analyze the causes and take measures to rectify them to ensure the quality of floor construction. For example, the use of a concrete laser leveler can improve the flatness and levelness of the floor. Regularly check its leveling effect and make timely adjustments if there is any deviation.

🎨  Construction safety management: Establish a safety management system, clarify the responsibilities of safety management personnel, and strengthen safety management at the construction site. Conduct safety education and training for construction personnel to improve safety awareness and self-protection capabilities, and require construction personnel to comply with safety operating procedures and correctly wear and use personal safety protection equipment. Set up obvious safety warning signs at the construction site and equip it with necessary fire-fighting equipment and first-aid medicines. Strengthen safety inspections, timely discover and eliminate safety hazards, immediately stop construction at locations with safety hazards, and take measures to rectify them.

🎨  Construction progress management: Develop a construction progress plan, clarify the construction tasks and time nodes at each stage, and report to the supervision unit and the construction unit for review and approval. According to the progress plan, reasonably arrange construction personnel and construction equipment to ensure smooth progress. Regularly check and analyze the construction progress, promptly discover factors that affect the progress, and take effective measures to adjust to ensure that the floor construction is completed on time. For example, the use of concrete laser leveling machines can improve construction efficiency. It is necessary to reasonably arrange its working hours, give full play to its role, and speed up the construction progress.

🎨  Construction cost management: Establish a cost management system, clarify the responsibilities of cost management personnel, and strengthen cost control during the construction process. Strictly control the procurement cost of floor materials, and select material suppliers with reliable quality and reasonable prices. Reasonably arrange construction personnel and construction equipment to improve construction efficiency and reduce costs. Strengthen cost accounting at the construction site, keep abreast of cost trends, analyze and adjust cost deviations, and ensure that construction costs are controlled within the budget.

🎊  Construction acceptance stage

🎨  Acceptance standards: After the floor construction is completed, the acceptance shall be carried out in accordance with the design requirements and relevant construction specifications. The acceptance content includes that the floor surface is flat and smooth, without defects such as cracks, hollows, and sanding; the floor color is uniform and consistent, without obvious color difference; the floor strength meets the design requirements, and the compressive strength test report should be complete; the floor slope meets the design requirements, the drainage is smooth, and there is no water accumulation.

🎨  Acceptance procedures: After the construction unit completes the floor construction, it will first conduct a self-inspection. After passing the self-inspection, it will submit the project inspection form to the supervision unit, and attach construction records, quality inspection reports and other materials. After receiving the inspection form, the supervision unit will organize the construction unit, construction unit and other relevant personnel to conduct acceptance. The acceptance personnel will inspect the floor according to the acceptance standards and fill in the acceptance records. For the problems found during the acceptance, the construction unit will promptly rectify them, and resubmit the acceptance application after the rectification is completed until the acceptance is qualified.

🎨  Acceptance materials: Floor construction acceptance materials should include construction drawings, construction plans, technical briefing records; floor material quality certification documents, inspection reports; construction records, such as base treatment records, floor material laying records, construction process control records, etc.; quality inspection reports, including floor flatness test reports, floor strength test reports, etc.; project inspection reports, acceptance records, etc.

🎊  Finished product protection stage

🎨  Protection measures: After the floor construction is completed, take protective measures in time to prevent the floor surface from being polluted and damaged. When performing other operations on the completed floor, take protective measures such as paving and covering to avoid damaging the floor. It is strictly forbidden to stack heavy objects, drag tools, etc. on the completed floor to prevent scratches, dents and other defects.

🎨  Protection responsibility: The construction unit is responsible for the protection of the finished floor, formulates finished product protection measures and organizes their implementation. Each construction team shall do a good job in the protection of the finished floor within the construction scope of the team, and repair it in time if there is any damage. The supervision unit shall strengthen the supervision and inspection of the protection of the finished floor, and require rectification in time if problems are found.
