The main principles of modular construction are:

• Prefabrication: Modular components are manufactured in a controlled environment, which increases production quality and efficiency.
• Quick assembly: The prefabricated modules can be assembled quickly and efficiently on site, resulting in shorter construction times
• Sustainability: Modular construction reduces material consumption and the environmental impact of building projects, as there is less waste and the modules can be reused or recycled.

The advantages of modular construction in Lean Construction include:

• Greater efficiency: Prefabrication and rapid assembly shorten construction times and use resources more efficiently.
• Better quality: The controlled production of the modules leads to a higher quality and durability of the components.
• Environmental friendliness: Modular construction helps to reduce material consumption and environmental impact, making it a more sustainable option compared to traditional construction.
