Modular construction is an efficient, green, and flexible way of building by dividing a building into modules, with most of the construction done in a factory and then transported to the site for assembly. ‌ This way of building has several notable features: ‌1‌ Efficient construction ‌ : Modular buildings significantly improve construction efficiency by pre-manufacturing building modules in factories, which greatly shorten construction time and reduce on-site operations.

‌2. Green Environmental Protection ‌ : Since most of the construction work is completed in the factory, the noise, dust and other environmental pollution at the construction site are reduced, which is in line with the concept of green building.

3. Flexible and variable ‌ : Modular buildings can customize functional modules according to needs, adapt to different use scenarios, such as hospitals, office buildings, factories, etc., and are easy to change and expand.

‌4. Quality control ‌ : The construction is carried out under controlled factory conditions, which ensures the quality and safety of the building and avoids uncertainties in site construction.

5. Easy to transport and install ‌ : Modular building parts are easy to transport, can be quickly assembled on site, and fit into a variety of terraforms and environments.

The origin of modular architecture can be traced back to the development of industrial architecture, which uses factory conditions and mass production technology to build houses in the way of "building blocks", which not only improves the construction efficiency, but also ensures the quality and safety of buildings. This construction method has been widely used in emergency support, temporary buildings, as well as hospitals, office buildings, factories and other scenarios, demonstrating its strong adaptability and practicality.

Modular buildings achieve a high degree of standardization and automation by prefabricating building modules in the factory, which greatly reduces the on-site construction time. Module manufacturing in the factory is carried out in a controlled environment, which is not affected by external factors such as weather, ensuring stable quality and high efficiency. At the same time, the factory and site construction can be carried out in parallel, and the modules only need to be assembled after they are transported to the site, which greatly reduces the labor demand and construction time on the site, thus speeding up the whole construction process and improving construction efficiency. More than 90% of the work of modular buildings can be completed in the factory, which is incomparable to on-site construction.

Traditional construction Each process of traditional construction needs to be completed on site, and the construction period is obviously affected by the skill of workers, weather and other reasons. Each floor has to repeat the reinforcement, formwork and concrete pouring, and the construction of the next floor can only be carried out after the strength of concrete reaches the standard, which is time-consuming and labor-intensive. Modular construction can effectively solve the above problems.

The rapid development of modular building technology relies on technological innovation, material advancement, market demand driven, policy support, and expansion of application fields. With these factors, modular building is gradually becoming an efficient, economical and environmentally friendly building solution, bringing new possibilities to the construction industry in the future.

Although modular building is a new building system, there are many technical problems to be solved, but relying on the support of advanced technology at home and abroad, the tilt of government policies, and the unremitting efforts of practitioners, the development speed of modular building technology is considerable.
