SYSTEM AND METHOD TO STABILIZE A PREFABRICATED STRUCTURE

1 . A prefabricated structure having improved stability, comprising:

a shell including a shell frame comprising:

a floor support;

a ballast device including one or more ballast tanks provided in the floor support; and

an extension deployable from the shell.

2 . The prefabricated structure of claim 1 , wherein the ballast device includes:

a supply water tank provided in the floor support; and

a grey water tank provided in the floor support.

3 . The prefabricated structure of claim 2 , wherein one or both of the supply water tank and the grey water tank has a baffled structure to guide movement of supply water within the supply water tank.

4 . The prefabricated structure of claim 2 , wherein the shell frame includes a channel to communicate a supply water duct connected with the supply water tank and to communicate a grey water duct connected with the grey water tank.

5 . The prefabricated structure of claim 2 , wherein the ballast device spans the length of the shell.

6 . The prefabricated structure of claim 2 , wherein grey water collected in the grey water tank is chemically treated; and

further comprising a mechanism to release grey water form the grey water tank to the environment so that a target volume of grey water is maintained in the grey water tank to provide ballast.

7 . A prefabricated structure having improved stability comprising:

a shell having a shell frame with a floor support;

an extension deployable from the shell; and

a ballast device associated with the shell frame to lower a center of gravity of the shell.

8 . The prefabricated structure of claim 7 , wherein the ballast device includes:

a supply water tank located in the floor support, and

a grey water tank located in the floor support.

9 . The prefabricated structure of claim 8 , wherein one or both of the supply water tank and the grey water tank has a baffled structure to guide movement of supply water within the supply water tank.

10 . The structure of claim 7 , wherein:

said ballast device is located in the floor support.

11 . The prefabricated structure of claim 8 , wherein the shell frame includes a channel to communicate a supply water duct connected with the supply water tank and to communicate a grey water duct connected with the grey water tank.

12 . The prefabricated structure of claim 7 , wherein the ballast device spans the length of the shell.

13 . The prefabricated structure of claim 8 , wherein grey water collected in the grey water tank is chemically treated; and

further comprising a mechanism to release grey water form the grey water tank to the environment so that a target volume of grey water is maintained in the grey water tank to provide ballast.

14 . A method of stabilizing a prefabricated structure comprising:

receiving a prefabricated structure including

a shell with a floor support;

an extension deployable from the shell;

a ballast device located in the floor support to lower a center of gravity of the shell, the ballast device including:

a supply water tank;

positioning the prefabricated structure at a deployment site;

deploying the extension from the shell; and

filling the supply water tank with supply water.

15 . The method of claim 14 , further comprising:

Receiving a prefabricated structure with a grey water tank;

allowing grey water to fill the grey water tank until a first target volume is reached; and

releasing grey water to the environment when a second target volume is reached.

16 . The method of claim 15 , further comprising:

chemically treating the grey water before releasing the grey water to the environment.

17 . The method of claim 14 , wherein the shell frame is a channel to communicate a supply water duct connected with the supply water tank; and further comprising:

communicating rain water to the supply water tank; and

treating the supply water for use in the prefabricated structure.

18 . The method of claim 14 , further comprising:

leveling the shell so that liquid in the ballast device is generally evenly distributed.

19 . The method of claim 14 , wherein positioning the prefabricated structure at the deployment site further comprises:

repeatedly performing the following steps until the prefabricated structure is supported by the deployment site:

suspending at least a portion of the prefabricated structure so that a column of the shell frame is unobstructed from the deployment site, and

lowering a support leg from the column; and

wherein leveling the shell comprises adjusting a distance the support leg extends from the column.
