Modular Home Building Platform Foundation 1
Modular homes can be placed on treated wood foundations that are above or below ground. The diagram below shows a foundation that can be used as permanent modular home building platform. When construction is completed the home can be moved to another location. The building platform foundation and the modular home have separate floor joists. The foundation in the diagram has two sets of joists to prevent it's walls from spreading apart. Before moving a modular home, the header floor joist lift points for the crane's two cable slings, are located and drilled. The lift points are usually located one half inch from the bottom of the joist and one third to one quarter from each end. They will be ten feet from each end if the home is longer than forty-six feet. For extra lifting security, the header floor joists can be doubled during construction or temporary scabs can be attached to the joists. Spreader bars can be used to keep the cable slings from damaging the building's walls.
