Designing an industrial factory, especially a large-scale facility, is not merely about constructing a production space — it is the foundation that determines operational efficiency and the long-term growth of a business. For large-scale factory projects, every aspect of the design requires a high level of expertise, a deep understanding of technical standards, industrial structures, and real-world operational demands. A poorly calculated design from the outset can lead to enormous unforeseen costs, safety risks, and even disrupt the entire production chain.
Therefore, investing methodically in factory design not only helps businesses optimize operational costs but also establishes a solid competitive advantage within the industry. In this article, BIC will comprehensively analyze the core technical requirements, modern design trends, and professional implementation processes specifically tailored for large-scale industrial factory projects.
A large-scale industrial factory refers to a production facility with a substantial floor area, typically 5,000 m² or more. These factories are designed to meet mass production needs, operate complex assembly lines, or serve industrial-scale logistics activities.
Key features of large-scale industrial factory design include:
- Robust structures capable of bearing heavy loads from machinery and industrial equipment.
- Open spaces utilizing wide-span structures, minimizing interior columns to facilitate production flow and goods movement.
- Comprehensive technical infrastructure systems including electricity, water, fire protection, ventilation, air conditioning, wastewater treatment, and industrial internet.
- Flexible design, allowing for easy expansion or functional modifications when needed.
Thanks to these factors, large-scale industrial factories not only accommodate high-volume production demands but also optimize long-term operational efficiency and cost-effectiveness.
Large-scale factories are suitable for industries that require high production volumes and strict technical standards, including:
- Mechanical manufacturing and automobile assembly: Requires expansive spaces, high load-bearing capacity, and flexible layouts to assemble large components.
- Industrial food and beverage production: Demands large areas for hygiene standards, wastewater treatment systems, and raw material storage.
- Warehousing, logistics, and distribution centers: Large factories allow for massive goods storage and support efficient inbound and outbound logistics operations.
- Large-scale electronics assembly: Requires cleanroom conditions, stable temperature and humidity control, and layouts compatible with automated production lines.
Throughout the design process, strict adherence to applicable building codes and legal regulations is mandatory. Key standards include:
- Fire protection standards (TCVN 2622:1995): Guidelines for fire safety design in industrial buildings.
- Steel structure standards for industrial construction (TCVN 5575:2012): Requirements ensuring strength and safety for steel frame designs.
- Environmental and labor safety regulations: Solutions must be integrated for noise control, wastewater and emission treatment, and ensuring a safe working environment for employees.
Moreover, the design documentation must be complete and compliant to obtain building permits and operational licenses, mitigating legal risks later.
An efficient large-scale industrial factory requires a scientifically planned layout between functional zones:
- Production area: Positioned centrally, near raw material sources and with convenient internal traffic access.
- Warehousing area: Located adjacent to production to optimize goods transportation.
- Administrative and technical support areas: Segregated from production to minimize noise and dust interference.
Internal traffic paths for trucks and forklifts must:
- Meet the minimum width standards for industrial design.
- Minimize overlapping intersections that could cause congestion or operational hazards.
Proper site planning enhances production efficiency, reduces operational costs, and increases workplace safety.
Operational safety is vital in the design of large-scale industrial factories. Requirements include:
- Emergency exits and escape routes: Clearly marked, easily accessible, and prominently signed.
- Fire safety zones: Equipped with fire extinguishers, automatic fire alarm systems, and sprinkler systems.
- Distance between production zones: Meeting minimum requirements to prevent fire and ensure rescue accessibility.
A well-structured safety design minimizes operational risks and protects both personnel and assets.
Accurate anticipation of production loads and appropriate selection of load-bearing systems are critical:
- Dynamic loads: Includes machinery operations, forklifts, and mobile equipment.
- Static loads: Includes stored goods and the weight of the factory structure itself.
Structural components such as the main steel frame, columns, and beams must use high-strength steel and be designed for long-term durability, deformation resistance, and foundation stability.
Furthermore, future production expansion needs must be considered to ensure stable operations throughout the facility's lifecycle.
Selecting the right foundation and floor system based on the site's geotechnical conditions is critical:
Foundation types:
- Strip foundations for firm soils with uniform settlement characteristics.
- Centrifugal pile foundations for weak soils to transfer loads to stronger strata.
- Reinforced isolated footings for areas with concentrated heavy loads.
Flooring:
- Typically uses concrete with strength ≥ 250 kg/cm² for high load resistance.
- Surfaces treated with hardener to resist dust, abrasion, and prolong maintenance cycles.
Accurate foundation and floor design ensure long-term stability under dynamic and static loads.
Pre-engineered steel frames are now the preferred solution for large-scale industrial factory designs due to:
- High load-bearing capacity suitable for large-span, high-load applications.
- Rapid construction time compared to traditional reinforced concrete.
- Ease of future expansion and modification.
Key considerations for steel frame design:
- Accurate calculation of beam, column, and bolted joint sections.
- Resistance to hurricanes and earthquakes up to grade 7–8 according to Vietnamese standards (TCVN 2737:2020).
A robust steel frame ensures factory resilience under extreme weather conditions.
Clear height and span width are crucial technical parameters affecting operational efficiency:
- Clear height: Typically ranges from 7m to 12m depending on crane usage, forklift operations, or industrial production lines.
- Wide span widths: Ranging from 18m to 30m, allowing:
+ Spacious, unobstructed production areas.
+ Minimizing internal columns for easier equipment and goods movement.
Proper height and span design significantly optimize construction costs and operational flexibility.
MEP systems are vital to maintaining continuous and safe factory operations:
- Industrial electricity:
+ Three-phase 380V supply ensuring sufficient power for machinery.
+ ATS (Automatic Transfer Switch) systems and backup generators for uninterrupted operations during power outages.
- Fire protection (PCCC):
+ Automatic sprinkler systems.
+ Addressable fire alarm systems for rapid hazard detection.
- Ventilation and cooling:
+ Cooling pads, industrial fans, and skylights to maintain a comfortable working environment while saving energy.
Properly designed MEP systems enhance safety, energy efficiency, and production reliability.
In today’s evolving industrial landscape, factory designs must prioritize sustainability, intelligence, and flexibility. Three key trends include:
As businesses increasingly prioritize operational cost savings and environmental responsibility, green factory design is gaining popularity:
