Setup of Mobile Toilets at Construction Sites

The setup of mobile toilets at construction sites should be systematically carried out through six stages: preliminary planning, location planning, installation and acceptance, daily maintenance, dynamic adjustment, and site clearance and settlement, ensuring that construction needs are met and hygiene and safety standards are complied with.

1. Preliminary Planning

• Headcount Estimation: Determine the number of toilet stalls based on the total number of workers, project duration, and peak periods. Typically, one standard toilet stall is allocated for every 50 people, with a recommended ratio of 1:1.5 for female to male stalls to accommodate higher female usage frequency.
• Site Survey: Choose a location that is flat, has good drainage, and is close to the construction area, avoiding material transportation routes, high-voltage lines, and low-lying areas prone to waterlogging to ensure no impact on work efficiency.
• Special Requirements: If there are high-temperature work areas on the site, communicate in advance with the rental company to add cooling equipment; barrier-free facilities should be configured according to regulations to ensure accessibility for disabled individuals.

2. Location Planning

• Zoning: Allocate one toilet stall for every 50-80 people in the construction area, prioritizing proximity to dense work points such as tower cranes and steel processing areas; set up stalls in the living area at a male-to-female ratio of 1:2, and configure 1-2 independent stalls in the office area.
• Accessibility: Ensure that toilet stalls are no more than 50 meters from the nearest work point, close to temporary roads, and avoid low-lying areas or near high-voltage lines; for large construction sites, a central dispatch point can be set up at the entrance to manage multiple stalls uniformly.
• Safety and Privacy: Keep toilet stalls at least 5 meters away from food areas such as canteens and water points, reserve lighting facilities for night work; ensure clear signage inside the stalls and good ventilation.

3. Installation and Acceptance

• Basic Layout: Place mobile toilets according to the planned locations, ensuring spacing complies with fire safety regulations (≥0.5 meters) to avoid safety hazards caused by dense stacking.
• Drainage System: Connect to temporary sewage pipes or septic tanks, regularly inspect to prevent sewage overflow, and ensure compliance with environmental protection requirements.
• Acceptance Criteria: Check the integrity of toilet facilities (such as flushing equipment and door locks), ventilation performance, and signage clarity, which must comply with the 'Urban Environmental Sanitation Facilities Setup Standards'.

4. Daily Maintenance

• Cleaning Frequency: Clean at least once a day, increasing to twice a day during summer or peak periods, focusing on disinfecting high-contact areas such as door handles and flush buttons.
• Fault Response: The rental company should commit to arriving on-site for repairs within 2 hours to avoid equipment failures affecting construction progress.
• Peak Season Support: Prepare spare equipment in advance during holidays or high-temperature periods to prevent supply shortages due to sudden demands.

5. Dynamic Adjustment and Emergency Backup

• Headcount Changes: Adjust the number of toilet stalls according to personnel changes during construction, such as adding 2 stalls during concrete pouring periods.
• Rainy Season Response: Plan drainage facilities in advance to prevent toilet waterlogging affecting usage; regularly inspect septic tank capacity to prevent overflow.

6. Site Clearance and Settlement

• Site Restoration: Clear surrounding garbage before evacuation, restore the ground to its original condition, ensuring no stains or damage.
• Fee Verification: Clarify actual usage days, additional fees for capacity increases or repairs, etc., to avoid disputes.
• Document Retention: Request the rental company to provide fee invoices and equipment recovery certificates for financial reimbursement.
