Advantages and Disadvantages of Prefabricated Structures

If you are looking for advantages and disadvantages of prefabricated structures and construction then you came to the right place. The structure is made up of different elements. These elements are manufactured during the construction of the structure and on-site.

However, in order to eliminate construction difficulties, not to depend on the season and conditions, and to ensure that the work is completed quickly and quickly, the structural elements can be fabricated on-site or away from the construction site.

Structures built by combining pre-manufactured elements in a suitable way are called prefabricated structures.

Elements such as floors of structures, roof plates, beams, columns, rigid frames, wall panels, arches, domes, load-bearing walls can be made as prefabricated. All kinds of industrial structures, residences, commercial structures, art structures, port elements, retaining walls, auxiliary facilities are built with prefabricated elements.

The whole structure can be built as prefabricated, some of it can be built in situ and some of it can be prefabricated.

The prefabricated construction method has many advantages. These advantages are; are classified under the headings of quality, cost, time, safety, cleanliness, regularity, and ecology.

Here are the Advantages and Disadvantages of Prefabricated Structures:

Disadvantages of Prefabricated Structures

Besides the advantages of the prefabricated construction method, there are also disadvantages. Disadvantages; classified in terms of economic, social, technical, and aesthetic.


  • Prefabrication requires large economic investments.
  • Prefabrication requires regular and systematic financial power. For this reason, small and medium-sized construction investors have difficulties in using prefabrication.
  • The transportation cost may move away from rationality after a certain distance.


  • With prefabrication, there is a possibility that the need for manpower will be lost as a result of high levels of mechanization and unemployment will increase accordingly.
  • There is a need for qualified people during production, design, and construction.


  • Prefabricated components can be damaged during shipping. Therefore, the elements must be moved. The connection details of the prefabricated elements should be well resolved and resistant to corrosion.
  • Large prefabricated components require heavy handling-assembly equipment and precise measurement.


  • Prefabricated structures made of the same type of components may appear monotonous.
  • Modular coordination, which is a requirement of rational construction, can limit design flexibility.

Other Disadvantages of prefabricated structures

  1. There is difficulty in adding elements in the form of assembly to each other.
  2. Elements are difficult to move. (They are heavy.)
  3. Production is always made with qualified personnel.
  4. The difficulties for small construction investors to use prefabrication because it requires a systematic and regular economic power.
  5. Lack of economically strong investors.
  6. With the rapid increase in mechanization in the construction sector, the possibility of a great decrease in the use of manpower and an increase in the unemployment problem.
  7. It is stated that the suitable transport distance of prefabricated structural elements is between 100-200 km, and in some countries, even longer transport distances can be efficient. At transportation distances longer than these distances, prefabricated structures lose their economic suitability due to transportation prices.
  8. Some problems may arise in the strength of the prefabricated structure system under earthquake and dynamic loads.
  9. The need for large areas for prefabricated production in factories and the high economic power required for the establishment of a factory.
  10. The absence of a national control mechanism in the production of prefabricated structure elements and the lack of state policies in this regard.
  11. The need for workers with a qualified workforce in prefabricated construction works during production, construction and design phases is quite high.
  12. Coordination problems of production and assembly teams have negative consequences such as transportation and stocking problems.

Considerations in the Use of Prefabricated Elements

  1. The prefabricated element factory should be located at a maximum distance of 500-600 km from the construction site.
  2. Column axis intervals should be chosen in accordance with the standard and in such a way that the most elements can be used.
  3. Measures should be taken against horizontal loads and earthquakes, and the foundation and upper parts should work as a frame.
  4. Standard sections manufactured at the factory should be used in the project.
  5. There should be no obstacles to the transportation of the elements to the construction site and their assembly.
  6. Roof slopes should be determined by taking into account the reverse deflection of the prestressed elements.
  7. The forces at the junction points should be studied.
  8. There is an obligation to put joints between more than one prefabricated element.
  9. The same combination should be used as much as possible to ensure standardization.
  10. It is necessary to make it ductile so that the junction points are not affected by loads, effects such as breaking, breaking, and capacity reduction.

Barriers to the Development of Prefabrication

When the use of prefabricated structural elements in the construction field in Turkey is compared with the use of prefabricated construction elements in the world, it is seen that our country lags far behind. The substances that negatively affect the low usage rate and development of prefabrication are listed below:

  1. Believing in the judgment that the production cost of prefabricated structural elements is more expensive than the production cost with traditional methods.
  2. Since the products in the construction industry are more durable and long-lasting than the products in other industries, they cause a decrease in the amount of production after a certain time.
  3. Prefabricated structure users are not satisfied with the low performance of prefabricated structure elements, both architecturally (humidity, cracks, lack of creativity in design, etc.) and structural (poor performance under earthquake load, etc.).
  4. The use of prefabricated elements within a certain system and standard, not being able to meet the desired aesthetics and mobility, the restrictions it brings to architecture, and the realization of the same type of plans in regions with different economic and social characteristics cause the system to receive great criticism (Taş, 2004).
  5. The heavy and large size of the prefabricated reinforced concrete carrier elements and the distance between the construction site and the factory in many places cause the transportation cost to be high.
  6. Concerns about the reliability of the performance of prefabrication systems under different seismic loads.
  7. The lack of communication between the designer, the contractor, and the manufacturer within the scope of the management of the project can negatively affect the construction processes.
  8. The fact that prefabricated structure systems are not supported by the state does not limit their use (Taş, 2004).
  9. Physical barriers such as the unqualified structure of the workforce, insufficient production, and low capital accumulation.
  10. Inadequate engineers, contractor construction companies, and experienced workers during the project design of prefabricated structure elements
