By building in a controlled and consistent environment, there is greater quality control in what is built and gives better predictability to the outcome of the project.
With controlled factory settings, waste is significantly reduced because excess materials can be recycled on-site into other processes. Controlled storage also reduces material damage from weather.
Prefabrication puts workers in a controlled environment where many of the risks of traditional construction sites, such as working at heights and around weather conditions, can be avoided.
In a massive Vallejo, California off-site construction facility, Factory_OS is industrializing the way housing is built. The company improves productivity and efficiency by constructing modular units on an assembly line in a controlled factory setting to send on-site to make multifamily buildings. Its manufacturing technology allows the company to build high-quality homes 20% cheaper, 40% faster and with 70% less waste than traditional building construction.
Building information modeling (BIM) tools provide the key to much of the advancements in modular assembly as they allow for a detailed 3D visualization of components to ensure that the finished parts fit. BIM also provides the means to detail each component for precise manufacturing that may include wall-assembly templates and jigs, subassemblies that fit within wall frames, and automotive approaches such as robotic welding.
Cannistraro, a Boston-based mechanical construction firm, has grown to be widely recognized as a leader in modular construction technology.
