How to build Pre-fabricated steel warehouse?

Pre-fabricated steel warehouse is always a complicated problem for most people who want to invest in construction for production. Issues such as factory size, floor plan, materials, construction costs, construction progress… are always a question for investors.

The article will summarize the most important steps and notes during the construction process so that you can better understand and make the best choices for your project.

Steps to deploy factory construction

After applying for an investment license, the pre-fabricated steel warehouse process can divides into 3 steps as follows:

1. Factory design
2. Construction preparation process
3. Construction

Cost of Factory design

The cost of pre-fabricated steel warehouse is very large, so planning and agreeing on the plan takes a long time, but this step is very important because it helps the investor as well as the contractor understand the needs of the production process.

Later, avoid arising, change in the pre-fabricated steel warehouse process. Help the project complete on schedule and put into use soon, optimizing investment costs.

Factory design step usually includes 2 steps

• Design preliminary plan and Design construction drawings
• Preliminary plan design

After discussing and understanding the needs of the investor, depending on the different production areas, technology lines and factory sizes, the architects and engineers will concretize them with face drawings.

Workshop drawings at this stage need to clearly show pre-fabricated steel warehouse items, density, construction boundaries, internal roads, density of trees, drawings of fire prevention and exit…

Construction drawing design

After agreeing on the preliminary plan, the construction drawing design phase. This phase drawing will show in detail all construction items, each structural detail of architecture, foundation structure plan, pre-engineered steel frame drawing, connection nodes, material specifications, M&E, fire prevention drawings for each specific item such as:

• Factory
• Storehouse
• Office
• Canteen
• Underground tanks
• Power station
• Garage, guard house
• Gate, fence…

Parallel to this stage is the process of applying for pre-fabricated steel warehouse construction permits and fire protection permits make a factory estimate table giving each job and the specific volume of all items.

The set of construction drawings and cost estimates (BOQ) will be the basis for acceptance of construction work and completed work volume later.

Set up pre-fabricated steel warehouse measures

The construction progress of the factory usually takes place very quickly, so each incident affects the overall progress of the project. Therefore, the preparation must be done carefully and in as much detail as possible.

To ensure that the construction process of the pre-fabricated steel warehouse takes place sequentially and to ensure the progress, the construction contractor needs to make a drawing of construction methods and a detailed construction schedule table for each item and each job.

Is location and site important pre-fabricated steel warehouse?

The site drawing of the construction organization needs to clearly show locations such as service roads, material gathering and processing yards, worker camps, operating rooms, etc. Besides, detailed drawings of measures should be shown. Current construction direction, necessary construction machines…

The pre-fabricated steel warehouse construction progress table should clearly show each specific work and item, including the stages of site preparation, temporary camps, time for electricity and water connection, construction and acceptance stages. , including the cleaning work, handing over after finishing the construction work.

Construction of factories on the construction site

Depending on the project, there are different construction stages, but basically it can divide into 4 main phases:

1. Construction of foundation items
2. Production of steel structures at the pre-fabricated steel warehouse
3. Construction and erection of prefab factory and covered corrugated iron roof
4. Finishing the workshop and installing equipment
5. Finally, the installation of equipment and production lines

Construction of the factory foundation

Immediately after handing over the ground, the contractor carried out the construction of the factory foundation. Depending on the geology and live load requirements of the pre-fabricated steel warehouse, it is possible to choose the solution of pile foundation or single foundation.

After the concrete foundation work, the contractor pours the soil and compacts the ground according to the requirements of the design drawings, and also creates the ground to prepare for the assembly and erection of the steel structure right after.

Producing pre-engineered steel frames at the factory

The production pre-fabricated steel warehouse house components carries out in parallel with the foundation construction stage so that the pre-engineered steel building can be transported and erected as soon as the foundation concrete has sufficient strength, helping to speed up the construction progress. .

• Construction and erection of steel frames

In addition to ensuring quality and progress, the construction phase of steel buildings needs to ensure safe work during construction and erection. All risks must be kept to a minimum.

• Construction of completed items

Immediately after the steel structure erection complete is the finishing work such as building walls, plastering ceilings, floors…

• Construction of electromechanical systems

 Factory construction unit price

The pre-fabricated steel warehouse construction unit price constitute by the following elements:

• Cost of materials
• Labor costs
• Cost of transporting machinery
• Management costs

The cost of building a factory depends on many factors such as factory size, construction location, progress requirements and finishing quality… Therefore, each project type will have a different unit price..

What does it cost us to build a warehouse?

The construction of warehouses has become very popular with the widespread use of so
-called “fast” technologies. Most often, customer companies build premises for themselves,
taking into account the specifics of their business. Let’s see which warehouse structures are the most
popular, and in what cases they use.

When it comes to pre-fabricated steel warehouse, it means the construction of lightweight
metal structures. They do not require a deep foundation, have a small mass
in comparison with reinforced concrete or brick, and most importantly, they are assembled in a matter of days. This means that the cost of the building is reduced.

There are only two types of such technologies

1. LMK (light metal structures) – products made of hot-rolled ferrous metal with a
   thickness of 4 mm and above.
2. LSTC (light steel thin-walled structures) – products made of galvanized steel
   up to 4 mm thick.

Both technologies cannot call new – they are several decades old. Their popularity increases, rather, in connection with the advent of a huge range of facing materials.

Therefore, not only cold pre-fabricated steel warehouse are being built from LMK and LSTK, but also heated buildings – hangars, sports centers, shops, etc.
