1. What exactly is prefabrication and modular construction in architecture and engineering?

Prefabrication and modular construction are methods of building in which portions of a structure are built off-site in a factory-controlled environment, and then transported to the final site for assembly.

In prefabrication, individual components of a structure such as walls, floors, or roof panels are manufactured off-site and then transported to the construction site for assembly. These components can be made from various materials such as wood, steel, concrete, or composites.

Modular construction takes prefabrication a step further by producing entire sections of a building that can be connected together on-site to create a larger structure. These sections, also known as “modules”, can include multiple rooms or even whole floors of a building.

2. How does prefabrication and modular construction differ from traditional construction methods?

Traditional construction methods involve building every component of a structure on-site from scratch. This requires extensive planning, manual labor, and coordination among different trades. In contrast, prefabrication and modular construction allow for more efficient and streamlined processes by moving some of the construction work off-site.

Some key differences between prefabrication/modular construction and traditional methods include:

– Location: Traditional construction takes place entirely at the final site while prefabrication and modular construction occur both off-site (in factories) and on-site.
– Process: Traditional methods involve sequential on-site construction whereas prefabricated components can be manufactured simultaneously in a controlled environment.
– Speed: Due to the controlled environment in which they are produced, prefabricated and modular components can often be manufactured much faster than traditional site-built materials.
