Section 9 Office & Welfare Space Calculation
This document summarizes general principles regarding "Office and Welfare Spaces" in distribution center design.
A distribution center is not merely a facility for storing and processing goods; it is a workplace for many people. This section explains area calculation methods and design considerations for creating employee-friendly environments that enhance productivity.
1. Necessity of Office and Welfare Spaces
To run distribution center operations smoothly, auxiliary facilities for management and support are indispensable alongside material handling zones.
- Operational Control Tower (Office):
Administrative workspace is required to direct and manage on-site floor operations, including inbound/outbound order document processing, vehicle dispatch coordination, Warehouse Management System (WMS) operation, and customer service.
- Improving Employee Satisfaction (ES) & Retention (Welfare):
Providing comfortable break rooms, cafeterias, clean locker rooms, restrooms, and shower facilities directly improves working environments. In the logistics industry, where recruiting talent has become increasingly challenging in recent years, well-equipped welfare facilities represent a critical factor in recruitment activities and employee retention.
2. Basics of Area Calculation Methods
Floor area for office and welfare spaces is calculated fundamentally based on "Headcount Usage". Below are standard square meter (m²) benchmark guidelines:
| Space Category |
Area Benchmark Guideline (per Person) |
Key Calculation Points |
| Office Space |
Approx. 5.0 to 10.0 m² |
Includes desks, chairs, aisles, cabinets, and office equipment. Calculated based on management staff headcount. |
| Break Room / Cafeteria |
Approx. 1.5 to 2.0 m² |
Calculated assuming concurrent users during peak times (e.g., shift meal break windows). |
| Locker Room / Changing Room |
Approx. 0.5 to 1.0 m² |
Secures necessary space for lockers and changing while considering gender ratios. Based on total workforce headcount. |
In addition to these, shared common area footprints such as conference rooms, reception rooms, restrooms, kitchenettes, and hallways are added to determine total facility size. Generally, these auxiliary facilities combined account for roughly 5% to 10% of total building gross floor area.
3. Important Considerations for Design and Planning
Beyond securing adequate floor area footprints, careful attention must be paid to layout and statutory requirements.
- Accounting for Peak Headcount:
Break rooms and restrooms experience concentrated usage during specific time slots such as pre-shift periods and lunch breaks. Capacity should be designed assuming the "maximum concurrent headcount (peak headcount)" rather than relying solely on total employee counts.
- Traffic Flow Planning and Security:
Pedestrian flow lines between "Work Areas (Floor Operations)" with active forklift/truck traffic and "Office / Welfare Areas" must be strictly separated for safety. Additionally, when designing truck driver waiting lounges, layouts must prevent external personnel from entering security-restricted zones.
- Compliance with Legal Regulations:
Facility designs must satisfy statutory standards under the Industrial Safety and Health Act and Office Health Standards Regulations regarding restroom fixture counts per employee headcount, break facility installations, ventilation, and natural lighting. Ensuring emergency evacuation routes compliant with the Building Standards Act and Fire Services Act is also mandatory.
- Future Scalability:
To accommodate business growth or temporary staffing increases during peak seasons, flexible layout designs with sufficient capacity to add lockers or desks later are highly desirable.
