Definition of Modular construction by the American Institute of Architects:

“The process by which components of a building are prefabricated off-site in a controlled setting and then shipped to the project site and assembled.”

Problem Statement

Modular Construction manufactures off-site building components or modules designed to fit together. This process offers several advantages: efficiency increment, waste reduction, quality control improvement, and shorter construction times. However, the process can be further improved using advanced technologies and engaging the administration to normalize this construction process in our cities. 


The use of computational design and BIM have already improved modular Construction by enabling the creation of building 3D models. These models improve the coordination between the different disciplines involved in the project, optimizing the process and detecting potential clashes between disciplines during the design. 

BIM and computational design have the added benefit of facilitating the utilization of CNC machines, resulting in enhanced precision and efficiency throughout manufacturing. Employing automation, robotics, machine learning, and AI can further improve modular Construction.


The podcast explores the current state of modular construction, future strategies in this field, and the contribution of new technologies such as BIM, robotics, machine learning, and AI.

Woh Hup is the leading construction company in Singapore, building iconic projects with vast experience in PPVC (Prefabricated Prefinished Volumetric Construction), technic widely used in the country.

Main Conclusions

  • BIM represented a significant change from the old way of building modular construction. Before had to rely on very skilled workers, and it took more work to coordinate the process on-site, resulting in time delays and material waste.
  • Normalizing the use of modular construction in our cities requires government support in the form of legislation and incentivizing their implantation.
  • BIM and new technologies play an essential role in improving the system and efficiency. However, the system can be further improved.
