Prefabrication can offer several benefits when building a residential building with 11 floors. It can significantly reduce construction time by manufacturing building components off-site and assembling them on-site, resulting in faster project completion and reduced costs. Prefabrication can also improve the quality and consistency of building components, as they are manufactured under controlled conditions in a factory, leading to a higher quality finished product.

Prefabrication can also reduce the environmental impact of construction, minimize waste and improve material efficiency, making it a more sustainable building method. It can offer greater flexibility in design and customization by easily modifying and adapting building components to meet specific project requirements. This allows for greater creativity and innovation in building design while still maintaining the efficiency and cost-effectiveness of prefabrication. In summary, using prefabrication for a residential building with 11 floors can improve construction efficiency, quality and consistency, environmental sustainability, and design flexibility.
