Smart construction
Modern Methods of Construction or MMC is a term used for modern construction methods. About two and a half million years have passed since the Stone Age and living in caves. Mankind at that time relied on the tools and equipment he made from all kinds of stones. Gradually and during the comprehensive evolution of mankind, we have witnessed remarkable feats in the world of building innovation. Innovation that has reached its highest level in the last 40 years. At this time, alternative construction methods have become increasingly popular around the world due to time, energy and cost savings. Methods known as MMC. It is interesting to know that since the Second World War and the urgent need to quickly deliver new housing, modern construction methods have been used under the title of “smart construction”. In this article from the Parsland series of articles, we will examine some of the most important and up-to-date construction methods in the world.
MMC, a short review
In one sentence, modern construction methods can be explained in such a way that the focus of these new methods is on the use of off-site construction techniques that can benefit from factory conditions and mass production techniques. In fact, with the development of technology and the discovery of new raw materials, yesterday’s traditional construction methods have turned into methods based on modulation and prefabrication.
In the fourth industrial revolution, which is related to digitalization in all areas, the construction industry has forced to reduce costs by using new technologies. In this method, the production of building elements in factories brings significant advantages in terms of quality control, transportation and speed.
For example, this has made the use of steel common in the construction industry. Technically, the new era of construction makes the use of modular structures inevitable. In addition to technical reasons, modular structures will transform the future of the construction industry with changing social needs, thanks to the recyclability and sustainability of modern building materials.
Therefore, in the near future and with the development of technology, prefabricated modular structures will be used to build large and multi-story buildings such as hospitals, shopping centers, social and luxury residences, office buildings, hotels, dormitories, schools, and clinics.

10 of the most important modern construction methods
In this section, be with us by reviewing 10 of the most important new construction methods.
1. modular technology; One of the most important modern construction methods
The first thing we discuss in the review of the most important modern construction methods is modular construction technology. But what is meant by modular construction? Stay with us in the rest of this episode with the answer to this question. Volumetric modular construction is a type of off-site construction in which the construction process is carried out by connecting a series of relatively large prefabricated sections or “modules” together. You often know this construction method as prefabricated construction.
Different methods of modular construction method have been defined; But the main type involves putting together and assembling prefabricated components in factories. This issue increases the speed of construction and reduces the need to work on the building.
2. Construction with flat slabs or prefabricated panels
This new construction method, which is somewhat similar to the previous one, refers to the use of flat concrete slabs for the construction process. These flat concrete slabs are reinforced using concrete columns and in this method there is no need to use load bearing beams. By using this method, there is no longer a limit on the height between the floors. On the other hand, the time required for construction is also greatly reduced. The construction method using concrete slabs is a flexible method that leaves your hand open for arranging the plan.
Prefab panels are where floor and wall units are built off-site and transported to be built on-site to form a solid structure which can be ideal for things like new builds where repeat projects are being built.
Similar to other prefabricated methods, this method offers speed, accuracy and quality, as factory components undergo a rigorous process before being easily installed on site. Panels can also include windows, doors and furniture, which provides the designer with flexibility in production.
3. Wooden frames
The use of wooden frames is another new construction method in the world. The use of a wooden frame in the construction of a wooden house is very popular in some parts of the world. In this case, a wide range of structural frames are used. Frames that are manufactured off-site in a factory and then transported to the project site. External and internal walls, flooring and ceilings are some of the applications of timber framing to help form a composite structure using other materials such as brick.
Timber frame construction uses a wide range of structural frames that are fabricated off-site in a factory, such as exterior and interior walls, floors, and ceilings. In general, making a wooden frame is a new construction method that is done using renewable and flexible wooden materials.
4. Twin wall technology
The fourth of the modern construction methods is twin wall technology. Twin wall technology is a method according to which both types of precast concrete and in-situ concrete are combined together, which helps to speed up the construction process and strengthen the structure. In this method, two concrete walls are connected to increase the strength and the gap between them is filled with concrete. This method is used to connect concrete walls and concrete floors. For this reason, twin wall technology is considered a fast and affordable method.
5. Thin joint masonry
Another method known as one of the new construction methods is Thin joint masonry. Thin masonry is an innovative construction method for using aircrete blocks in construction. This method, which has many practical and commercial advantages, allows you to significantly improve the build time. This method is mostly used for the construction of interior non-bearing walls. Numerous tests and investigations have shown that using this method, in only five to six days, the interior walls of a 2-story, 4-bedroom house will be built.
With this work, there will be no need for brickwork or external coating, and the construction schedule will be saved. Thin joint masonry is a modern accepted method of construction (MMC).
Some of the biggest advantages of this method are as follows:
* Increasing the speed of construction
* More productivity
* Better resistance and thermal performance
* Better insulation
* Reducing the waste of space
* Improve the quality of construction
6. Hybrid construction
As its name suggests, the hybrid construction method, as one of the new construction methods, uses a combination of existing and new methods.
Hybrid construction or semi-volumetric construction combines modern construction methods of modular/volumetric units and panel systems. In this method, volumetric units are often used in the construction of kitchens and bathrooms, and in general parts of the building that are used more often, and panels are used in other parts of the building. This new construction method allows you to use the best construction method in every part of the house.
7. 3D printing construction
3D printing in the construction industry, a subject that provides many possibilities to contractors and architects. 3D printing technology is one of the latest human achievements that can be used in many industries and business areas of the world. So that today, 3D printing has continuously created new and innovative methods in most fields, including in the construction industry. You might ask, what is the main use of 3D printing in the construction industry? In general, 3D printing is often used to make building prototypes, to check the conditions and analyze the possible behavior of the building in different conditions, as well as to create and manufacture complex components that have challenging shapes.
Using this new construction method, the 3D model is given to the system and the desired building elements are made, it’s amazing, isn’t it? Now that you are familiar with the most important new MMC methods, it is better to provide you with information about the benefits of these methods.
What are the benefits of MMC?
When we compare modern construction methods to more traditional methods, we find that these methods offer contractors, designers, and architects a wide range of benefits. In short, construction through MMC will be much shorter and more labor intensive, while allowing you to maintain the project’s quality level. But what are the most important advantages of new construction methods?
1. waste reduction
2. Less transportation required
