Industrialized construction, known as Building Assembly Manufacturing, is an offsite construction process. This means that everything that makes up the building is not built in situ (on site), but is created and assembled in the factory, by means of modules or elements that make up the building.
Industrialized construction, although underdeveloped in Spain, represents 1%. It is a construction system that is being developed in our country. In other countries it is a more widely used form of construction. In Germany and the United Kingdom it represents 9% and 7% respectively, reaching 50% in the Netherlands) due to its great advantages, both for the environment and for the end client.
This is due to the fact that industrialized construction is an innovative way of building, which is based on the advance of technology, revolutionizing the real estate sector. It provides a number of benefits that make it very competitive with a traditional system. It saves costs for both the builder and the end customer and, above all, achieves a lower environmental impact.
It is a construction system with multiple advantages over “traditional” construction. Not only because it is a quick construction to install on site once all its constructive elements are ready, but also because it is safer when working with specialized personnel, under controlled conditions inside a factory. It allows to automate the processes, achieving a greater control of costs and time, as well as the
control of human factor.
Another great benefit will be sustainability, the system as such allows reducing the consumption of resources such as water, energy, this will happen because the process is mostly done in the factory in a controlled manner and the intervention in the plot will be minimal.
The system is more environmentally sustainable because of its lower cost and shorter times, as well as the higher precision and quality of the finishes, offering additional advantages.
Within the options there are three predominant typologies depending on the materials used to manufacture houses. Prefabricated or modular: concrete, wood, steel in the latter there are two options either modular or steel frame, among the same typologies there are multiple combinations, adapting to the advancement of technology and search for more environmentally friendly materials and zero carbon footprint.
The three typologies will be:
To answer this question it is important to know that the industrialization process by which the houses are manufactured allows a global control of the development, so that the manufacture of the elements that compose it are subjected to a constant and demanding review where the strength, weight and stability are calculated, ensuring the safety of the construction.
An important aspect that will have an impact on the lifetime of a prefabricated house will be compliance with the Technical Building Code (CTE), meeting all the guarantees and requirements to be safe and sustainable housing, many of them achieving the maximum energy rating A.
Considering all the controls that a prefabricated or modular house must comply with. The life span would be above that of a traditional home, although there is no exact answer, studies give a ratio of an average life span between 50 and 70 years, depending on the correct execution in terms of deadlines and quality.
Traditional construction presents difficulties as variables at the time of execution. In the fulfillment of deadlines, depends on the time frame, it often depends on The weather is favorable Requires more personnel. All this means in most cases delays and lower cost control, points that will be controlled in an industrialized construction, where there is an automation of processes, controlling the execution in factory with qualified personnel, in a controlled work environment without climatic effects, assuming a saving in cost and time, managing to ensure a closed price, such as precision finishes.
This means that prefabricated or modular homes are built in less time compared to a traditional home. As the name says, many of them come ready from the factory, meaning a lower construction cost, being practical and efficient in terms of functionality and energy consumption.
By executing an industrialized construction model, risks are significantly reduced because it is easier to perform a complete traceability of the entire construction process, controlling quality and efficiency, with a more efficient management where execution times are reduced and profitability is improved.
