Advantages and disadvantages of popular models of 2-storey industrial factory

When the land fund for industrial construction is increasingly limited, the rental price of industrial real estate in Vietnam is continuously increasing in the last 10 years, the 2-storey factory is considered as one of the smart solutions, helping to optimize production space and optimize many costs.

Here are 3 popular 2-storey factory models that many investors are choosing:

1. 2-storey factory with reinforced concrete structure

This type of 2-storey factory uses concrete and reinforcement as the main material for both the floor and the roof.

Advantages:

+ Thanks to its incombustibility and low temperature conductivity coefficient, reinforced concrete structures can meet all regulations on fire prevention and fighting.

+ Reinforced concrete structures can perform well the two functions of fire prevention and good bearing capacity.

Disadvantages:

+ The construction process is complicated, with strict requirements on the number and size of foundations and piles, so it takes a lot of construction costs as well as construction time.

+ The low strength per unit of weight of concrete leads to the poor ability to overcome the long span structure, the number of columns to be constructed is quite large, affecting the production space inside the factory.

2. 2-storey reinforced concrete factory using steel structure roof

This is a modern, beautiful and cost-effective 2-storey factory type. Columns, foundations, beams, floors are made of reinforced concrete. Covering structure is made of steel frame roof trusses.

Advantages:

+ Good load capacity.

+ The steel structure roof truss has a light load, so the factory does not need many bearing columns, so the production space in the factory will be more spacious.

+ Save time on roof construction, optimize a part of construction costs.

Disadvantages:

+ Construction of reinforced concrete floors has a complicated process from installing formwork, reinforcement, columns…

+ In order to ensure fire safety and the acceptance of the factory, it is necessary to paint fireproof for some components such as roof trusses, 2nd floor steel columns, etc. to meet fire protection requirements.

3. 2-storey factory concrete placed on metal decking

Concrete decking is a processed steel corrugated iron floor, it acts as a permanent formwork and it bears the weight of poured concrete. This is a 2-storey factory model with the best application today, when overcoming most of the disadvantages of construction schedule and optimizing costs of other 2-storey factory models.

Sàn deck

Advantages:

+ Speeding up the construction schedule because it has reduced a number of stages compared to the traditional solution of using floor beams.

+ Optimizing construction costs, saving cost of formwork and supports.

+ In many cases, this method significantly reduces the self-weight of the floor, which can reduce the load on the foundation.

Disadvantages:

+ For projects that require complex beam systems, it is difficult to use concrete decking.

+ There are no specific instructions for the inspection of fireproof paint for load-bearing structures – hindering difficulties in the acceptance of fire protection for factories.

Depending on the scale and investment of the factory, the demand for use and the capacity of the factory, investors can choose a suitable type of 2-storey factory to deploy.

As a Design – Build general industrial contractor with extensive experience in 2-storey factory construction, DELCO can advise investors on a reasonable 2-storey factory model, suitable to the demand of each factory.
