Setup of Mobile Toilets for High-Rise Construction

The setup of mobile toilets for high-rise construction should be determined based on the building height and specific regulatory requirements. General recommendations are as follows:

I. Conventional High-Rise Buildings (8 to below 100 meters)

According to Article 5.1.6 of the 'Environmental and Sanitary Standards for Construction Sites', when construction height exceeds 8 floors, temporary toilets should be installed every 5 floors. For example, if a building has a total of 20 floors, toilets should be installed on the 8th, 13th, 18th floors, etc. This regulation aims to ensure the convenience of construction workers in accessing toilets while preventing sanitary issues caused by insufficient toilet numbers or improper placement.

Additional practical recommendations: Some construction sites install a mobile toilet every 4 floors starting from the 8th floor. This adjustment may be based on actual factors such as the number of workers, project duration, or available space on site. However, it is essential to ensure compliance with local regulations or corporate standards to avoid inconvenience caused by excessive spacing.

II. Super High-Rise Buildings (100 meters and above)

According to Article 6.6.3 of the 'Unified Standard for Civil Building Design' GB50352-2019, super high-rise buildings should have a mobile toilet installed every 3 floors during the construction phase. This regulation focuses more on the requirements for permanent facilities in building design standards but can be referenced during construction, especially in densely populated areas such as core tube construction. It is important to note that due to the low vertical transportation efficiency and long construction period of super high-rise buildings, the layout of mobile toilets should be denser to reduce the time workers spend going up and down the building and improve work efficiency.

III. Key Considerations

1. Hygiene and Maintenance: Mobile toilets should be equipped with septic tanks or regularly emptied to prevent sewage leakage. Daily cleaning and disinfection are necessary to prevent odors and the spread of germs.
2. Location Selection: Toilets should be placed near construction elevators or staircases for quick access by workers and away from main work areas to minimize interference with construction activities.
3. Quantity Calculation: The number of toilets should be dynamically adjusted based on the number of workers, with a general recommendation of 1 toilet per 20-30 workers, and additional toilets can be added during peak periods.
4. Compliance Verification: Before installation, it is necessary to confirm the requirements of the local housing and construction department or project owner. Some regions may have additional regulations on spacing and toilet types (e.g., squat/sit toilets).

Summary: The setup of mobile toilets for high-rise construction should be based on regulations and flexibly adjusted according to building height, number of workers, and site conditions. The core goal is to ensure the basic needs of workers and maintain sanitary conditions at the construction site.
