Off-site construction  is the fabrication of buildings in a controlled factory environment. Components of the building projects are pre-assembled while site preparation is underway. With this construction mythology projects can be completed up to 50% faster than traditional site-built projects, which is what the construction industry is demanding at present.    

• Quality: Modular buildings are constructed to the same building codes and standards as traditional buildings. However, the factory-controlled environment allows for greater quality control and consistency.
• Cost: Modular buildings can be more cost-effective than traditional buildings, especially for large and complex projects.  Modular construction is not directly subject to prevailing wage and project labor agreements since most work is completed in-factory.  
• Sustainability: Fabrication in a factory environment is more efficient and less wasteful resulting in a more sustainable construction project rather than traditional site-built construction.
• Reduced site disruption: Modular buildings are typically transported to the construction site and assembled on-site, which minimizes disruption to the surrounding area.
• Improved safety: Modular construction is generally safer than traditional construction because it takes place in a controlled factory environment.
• Increased predictability: Modular construction projects are typically more predictable than traditional construction projects because the factory-controlled environment allows for greater control over the construction process.

 Overall Off-site construction methodology offers a number of great advantages over traditional construction methods. It is faster, more cost-effective, more sustainable, and more flexible.
