The foundations of a modular home transfer the weight of the building to the land it is placed on. Since our homes are manufactured from shipping containers the foundation requirement is generally very cost efficient as a container home usually weighs less than a traditional brick house and the structure is also load bearing, however the foundation still needs to support their overall weight and there is no standard requirement for the foundations, it depends on the soil (or rock) the home is placed on. Engineers will need to study the properties of the soil to ensure that it can withstand the load of the buildings. It is common practice for an engineer to carry out a soil test to determine the safe bearing capacity of the soil. As an example, the SBC (safe bearing capacity) could be determined as 18 T/m2 (tonnes per square metre) this would be the maximum figure that the soil could hold per square metre of that land. This capacity also can change at different depths of the soil, usually the greater someone digs the greater the Soil Bearing Capacity.
