Bob Vila's Home Again on the DIY Network just finished a run of shows about a modular home under construction. I haven't seen the show, but it sounds like there were some good views into the factory and site process.
From the episode descriptions: Modern Modular:
"Bob Vila travels to western Massachusetts for a brand new project; the construction of a modular home in the Berkshire Hills. He goes to the Simplex Industries factory in Scranton, Pa., to see how the process starts. We talk with owner Pat Fricchione, Jr. about the history of the company, and how the image of modular construction has changed over the years."Wall Panels:
"Today, we learn about the manufacturing process for the precast panels for the walls. Next, we travel back to the Simplex plant in Scranton Pa., where Bob Vila explains how each module is framed. Back in the Berkshires, the assembly process is explained once the panels have been lowered into place by crane."Assembly:
"At the Simplex plant, several crews work as if on an assembly line to make fast work of each module. There's a lot happening, from spackle and sand, to insulation, wall and roof sheathing, house wrap, and interior trim. Bob Vila learns about the state-of-the-art wire boxes that are being installed, and we'll look at the staircase that's being built for the front hall from the stair shop."
A small picture of the home coming together can be seen on the Bob Vila web site.
