Seasonal construction monitoring?

Before entering seasonal (winter, rainy season, summer) construction, the construction unit should prepare a special construction plan and submit it to the supervision department for review. The Supervision Department shall supervise the implementation of the construction unit according to the construction plan and relevant regulations. Safety protection requirements for winter construction: It is not suitable to work at high altitudes in rainy and snowy weather. When the visibility in foggy weather cannot meet the operation requirements, no operation is allowed, especially hoisting operations. Ladders and ramps for people ascending and descending from construction scaffolding in winter should be equipped with anti-slip measures. After strong winds and snow, ice and snow must be carefully cleaned and removed in time. Check the stability of the scaffolding in a timely manner and eliminate hidden dangers in a timely manner. Offices, dormitories, work sheds (mixer sheds, etc.) must be closed before winter arrives, heating facilities must be installed, and insulation, heating, and windproof measures must be taken. Workers must wear gloves when working to prevent frostbite. When coal stoves are used for indoor heating, facilities must be provided to prevent gas poisoning. In addition to installing a chimney, the stove must also be equipped with a wind duct to ensure ventilation, and a dedicated person must be on duty to watch the fire at night. After the furnace and gas protection facilities are installed, they must be inspected and accepted by relevant personnel organized by the deputy project manager before they can be used. Inspections must be carried out regularly and irregularly. If industrial salt is used as antifreeze, it must be stored separately and clearly marked with warning signs to prevent consumption. Use flame-retardant materials as much as possible for thermal insulation materials, and adequate fire-fighting equipment must be provided in fire areas. Summer construction protection requirements: Certain heatstroke prevention drugs should be provided before starting work. Heatstroke prevention drinks and certain cooling equipment should be prepared at the construction site. In high-temperature weather (above 30°C), work and rest times should be reasonably arranged, and open-air operations should be avoided as much as possible during high-temperature hours. When working in hot weather, workers must have enough rest time and must not work fatigued. Screen doors and windows should be installed in employee dormitories to reduce indoor mosquitoes and flies and ensure that employees have a good rest. The site must be equipped with mosquito and fly extermination drugs, and mosquito and fly extermination should be carried out regularly around toilets and canteens. The canteen must be equipped with screen doors and windows, and a refrigerator must be installed. Overnight food should be stored in the refrigerator. It is strictly forbidden to eat spoiled food, and food must be stored in a fly-proof cover. Kitchen utensils and tableware must be washed after each use and disinfected if necessary. The project management department should regularly inspect the hygienic conditions of the canteen and rectify any problems found in a timely manner. Protection requirements for rainy season construction (protection against electricity, lightning strikes, and subsidence and collapse) require on-site drainage. Temporary road concrete is hardened and arched by 5‰ to ensure smooth drainage at the construction site and rainwater is discharged into the sump and the original Rain well. Before the rainy season, designated personnel are responsible for inspecting large temporary facilities. Scaffolding, lighting, power electromechanical equipment, etc. should be repaired and reinforced. For the protection of temporary facilities and equipment, scaffolding should be inspected promptly after strong winds and heavy rains, and any problems found should be dealt with immediately. Open-air construction equipment must be equipped with a rain shelter or rain cover. Raw materials, components and equipment that are afraid of rain, moisture, cracking and falling should be placed indoors and stacked on a solid foundation. Materials that cannot enter the room should be tightly covered with tarpaulins. Measures should be taken to prevent electric shock and explosion during electric welding. The zero connection, grounding wire, leakage protection device, etc. of various electrical equipment are complete and effective. The depth of buried wires or protective measures, as well as their aerial erection must comply with regulatory requirements. Arrange special personnel to check equipment and wires frequently to prevent leakage. Organize roof drainage. The backfill soil at the outdoor water distribution area should be dense. If the water distribution project is not completed before the rainy season, drainage measures must be taken to prevent rainwater from intruding into the foundation. A retaining wall should be installed at the entrance and exit of the underground garage to prevent rainwater from flowing into the basement. Do not operate at high altitudes in the open air during thunderstorms. Before the rainy season, the low areas of the on-site transportation road must be filled and compacted. Dredge drainage ditches to ensure smooth drainage. Slopes should be equipped with steps or anti-slip measures should be taken. Pay close attention to seasonal and climate changes, and take seriously the resulting safety risks: construction units are required to encounter severe weather such as strong winds above Level 6, thick fog, etc., and are not allowed to engage in open-air climbing or suspended operations at high altitudes. After snowstorms and heavy rains, safety facilities for high-altitude operations should be inspected one by one. If any looseness, deformation, damage or falling off are found, they should be repaired and improved immediately. After the construction of the main structure of the building is completed, the roof lightning protection system should be constructed as soon as possible. The roof lightning protection system must be completed before the rainy season arrives.
