Utilizing factory-based construction for 50 to 70 percent of the total building needs results in higher construction and project quality for several reasons:
Reduced waste
A quality labor force and the inherent Quality Control (QC)/Quality Assurance (QA) of a factory environment means less material waste versus conventional construction
Working conditions
A well-lit indoor space with a constant and comfortable temperature and protection from the elements provides a productive work environment for construction trades
Consistency
Reporting to a fixed location with no extraordinary commute to a job site leads to a more consistent schedule that allows workers to function more effectively
Fewer layoffs
As a result of a more controlled process at a fixed location, the best workers among the numerous trades required to construct a building are attracted to position permanency
Quality control
An integrated team of tradesmen who work together on numerous projects over a period of years lead to tighter tolerances, greater cooperation, and faster resolution of any sub-system interferences
On-site assembly
The stacking and connection of modules and sub-systems that are constructed to more rigorous factory tolerances makes the last 5 to 15 percent of the work much more precise
Materials
The same architect-specified materials used in conventionally constructed buildings are used in concurrent construction projects
Code requirements
The structural integrity of modules is built to withstand transportation from the factory to the site and meet or exceed the same building codes and standards as site-built structures
