The construction of precast concrete building is one of the many good options in the construction market.
In addition, the use of industrialized and labor-intensive construction processes has gained prominence in most industrialized countries . Industrialization adds a lot of value to the works, as it makes the construction faster and guarantees higher quality of the elements.
In recent years, several companies have focused on the construction of precast concrete houses and building . Each company has in its portfolio a certain amount of modulation option for the construction of the residences.
Being an industrialized process, the standardization of the elements is an important characteristic. This standardization guarantees the reuse of metallic forms, a greater control in the consumption of materials and in the facility to anticipate openings or installations.
In addition, each company has its internal process of manufacturing the structural elements. But, all must obey the current norms, in relation to the quality of construction and comfort for housing.

Main advantages of precast concrete
1 – Reduction of the term of the work:
One of the main advantages is the reduction of the term of the work. The manufacturing of the modules can be planned as the work progresses. Thus, the structure will only be mounted with the aid of a crane.
This reduction of deadlines eliminates several fixed costs, such as administration of the work. In addition to providing a quick use of the environment being built.
2 – Elimination of services:
Several services are eliminated compared to conventional constructions.
Every construction process eliminates several services at the construction site such as form, frame, concrete, masonry, part of the electrical and hydraulic installations. With the elimination of services reduces the need to purchase various inputs and reduce the size of the stock of the work.
3 – Cleaner construction:
Another advantage in building with precast concrete a cleaner construction.
A clean work has several benefits, such as:
- Reduction of waste;
- Reduced production of debris;
- Better use of the spaces of the construction site;
- Better quality in the work environment for employees;
- Reduction of costs with cleaning and boot-off;
- Reduction of aggression to the environment.
4 – Reduction of manpower:
Another constructive advantage is the reduction of manpower. Industrialization will eliminate much of the workforce at the jobsite.
The services of frame, carpentry and facilities are very small. This helps in reducing the cost of the work and in the maintenance of a minimum team for the assembly of the panels, construction of the cover and construction of the final finish of the work.
5 – Reducing costs:
One of the main advantages of precast concrete is the reduction of final construction costs.
This reduction may be significant in some cases. Before building it is worth consulting several builders and check the feasibility of this type of construction for the conditions of your work.
Main Disadvantages of Precast Concrete Houses
1 – Architectural limitation:
One of the disadvantages of the system is the architectural limitation. Most of the industries that manufacture the panels already have options in their portfolio for building houses.
The client must choose between the architectural designs already defined and negotiate any changes that can be made by the constructor.
2 – Limitation for future changes:
Changing a layout of a pre-molded home is also more complicated. It is not so simple to arrive and break a wall to enhance the environment or create a door or a window.
Renovations or extensions should be planned and well studied, if possible with the help of the builder who manufactured the house.
3 – Availability in more distant places:
Even with the expansion of this market to this type of construction, in some places it is still impossible to make the option for this constructive system.
In places very distant from the industries the transport of the pieces can economically make the option for the prefabricated houses of concrete impossible.
4 – Need for large initial investment:
In conventional constructions it is possible to build little by little. That is, expenses arise as you build. If necessary the owner can even stop the construction and continue in the near future.
In the case of pre-cast residences, a high initial investment in panel manufacturing is required. That is, you will have a great expense already at the beginning of the work, unlike the conventional construction.
Final considerations
Making the choice for precast concrete houses can be an excellent opportunity to make a quick, economical and extremely high quality construction.
It is worth mentioning that each construction is a new story, so before defining the use of any construction system it is important to consult a professional and study the economic viability of each system. It is important to take into account the terrain, the natural conditions of the site, the location and availability of labor.
