Crucial notes to build a high standard factory


Recently, office buildings and pre-engineered steel factories are increasingly focused on to meet production and business needs. Especially, safety during construction is a primary concern. Therefore, the issue of making the construction process safe, economical, and high-quality is seriously paid attention to. To learn more, let’s explore with BMB Steel the following notes when building a factory in the article below.

1. What should be noted when building a factory?

What should be noted when building a factory?

1.1 Aperture in construction

Aperture in construction is the distance from one edge of the column to the other. Another definition is the width of the building.

Depending on the land area and production needs, the construction aperture will be different. For example, aperture 15, 20, 30, etc.

1.2 Factory aperture

Factory aperture is the distance of the right side column edge to the left side column edge in the width of the factory. It is also known as the factory’s width. Factory aperture and construction aperture are calculated with different sizes such as 15m, 20m, 25m,...

1.3 Factory location

  • It is recommended to choose a well-ventilated location to build factories.
  • You should choose a location with lots of trees surrounding for fresh air.
  • Determine the size and area of ​​the factory.
  • The layout of the total ground is consistent with the current industrial plan and the investment owner's expansion plan.
  • Choose positions that can expand the scale of the factory.

1.4 Design standards in factory construction

The determination of the factory building location needs to be carefully calculated for future expansion. Especially, these following construction standards should be complied:

Vietnam Construction Regulation Vol. 1 ( by the Ministry of Construction, together with Decision No. 682/BXD-CSXD dated December 14, 1996).

Vietnam Construction Regulations Vol. 2&30 (by the Ministry of Construction, together with Decision No. 439/QD-BXD dated September 25, 1997).

Standards for each category:


  • The foundation must be built according to the TCVN 2737: 1995 standard.
  • The foundation area that will be drilled must be firm.
  • The height of the foundation must be lower than the ground.
  • The foundation requires expansion joints.
  • Materials: concrete, cement tile flooring, etc.

Roof, roof door

  • The roof should be designed with a slope that depends on the roofing material.
  • Factories with roof slopes less than 8% need to design concrete columns 
  • The roof door with the ventilation and light system must not be more than 84m wide.
  • Roof doors need to be glazed vertically.

Walls, partitions

There are types: load-bearing walls, wall frames, etc. Walls can be made from bricks, stones, etc. Brick walls require a waterproof layer. Walls between factories need to be installed for easy disassembly to meet the requirements of changing structure or repairing machinery.

Windows, doors

  • Windows and doors must have good light and ventilation.
  • Window’s height is not more than 2.4m
  • For wind and storm protection, windows with glass will be installed higher than 2.4m with a fixed frame.

1.5 Factory structure

Each factory has its own structure. Each space undertakes separate functions, so customers need to design to promote their functions and tasks.

1.5.1 Ceiling system

The erection of the roof is usually carried out after the erection of the main frame. During the factory construction, the joints of the ceiling system (especially the insulation joints) need to be paid attention to so as not to be stretched and wrinkled. Thus, this will ensure the durability of the ceiling.

1.5.2 The factory foundation system

  • Foundations are the most integral structure of any construction project.
  • When building the foundation, we should pay attention to the technical specification.
  • The materials for the foundation must meet the standards of TCVN and international standards
  • When choosing the location of the foundation, for each different type of ground, we have a different way of choosing a foundation: with a factory built on soft and muddy soil, it is recommended to use a solution of precast concrete pile and prestressed concrete pile. For factories built on hard ground, just build normal foundations.

1.5.3 Door system

  • Installing the door system is also very crucial.
  • Make sure the door is securely fixed to the wall, easy to open. The technique of installing the door must be very careful.
  • If the door is not installed properly, it will fall off after completion.

1.5.4 Partition wall system

The partition wall system must be designed and constructed meticulously to ensure the stability of the factory. Besides, it needs to ensure the consistency of the builder and installer when building pre-engineered steel factories.

1.5.5 Ventilation system

To ensure stable air circulation, the ventilation should be installed on ceilings, roofs or basements of manufacturing factories, petrochemical refineries, etc. When installing ventilation systems, we need to be concerned about these factors: calculating the required airflow to install the most suitable system. If the space is not sufficient, the ventilation door can be increased in size. A fan with low noise is a good solution for not affecting the production process.

1.5.6 Lighting system

Lighting system plays a vital role in the factory. Depending on the type of factory, the lighting requirements vary. For warehouses or production areas, etc when designing, it is necessary to carefully study the characteristics of the factory to choose the appropriate brightness.

Choose appropriate lighting for each area according to TCVN 7114-2008. In addition, you should make the most of natural light. LED lights will save money and electricity. Besides, its lighting efficiency is also higher.
