We will explore the benefits and value of Modern Offsite Cell Fabrication. We will answer why, where, when and how Modular Fabrication can and should be used. We will compare and contrast the benefits and shortcomings of both Steel Module and Prefabricated Concrete Cells. Modular construction can be used for any and all types of Justice Infrastructure. Modular construction adds value to a project through reduced cost, improved schedule, and enhanced quality. There are beliefs that modular will limit design, but we will show this not to be true. The historical view of Boxes no longer reflects the possibilities of Modular construction. We hope to broaden your knowledge, dispel the myths, and better your opinion of the value proposition of the use of modular. We want to show Designers and Owners how they can take advantage of the modern means and methods that Modular can provide.
