1. A carriage assembly comprising: a scaffold;a carriage frame for supporting the scaffold, the carriage frame consisting of four tubular frame members, wherein the tubular frame members are arranged and connected at their terminal ends such that they form a rectangular frame, wherein each end of each frame member has an open port for receiving a jack body, such that each corner of the rectangular frame consists of a first port oriented in a first direction and a second port oriented in a second direction that is substantially perpendicular to the first direction, wherein the first port and the second port have a substantially similar configuration;a caster; anda first jack body coupled to said carriage frame and said caster, said first jack body having a longitudinal axis, said first jack body configured to selectively move said caster with respect to said carriage frame along the longitudinal axis to enable a height of said carriage assembly to be selectively adjusted, wherein said first jack body is interchangeably coupleable to said first port and to said second port to enable a length of said carriage assembly and a width of said carriage assembly, respectively, to be selectively adjusted without requiring the scaffold to be disassembled from the carriage frame. 2. A carriage assembly in accordance with claim 1, wherein one of said tubular frame members of the carriage frame defines a first axis, said first jack body movable along the first axis. 3. A carriage assembly in accordance with claim 2 further comprising a second jack body coupled to said carriage frame, a second of said tubular frame members defining a second axis, said second jack body movable along the second axis. 4. A carriage assembly in accordance with claim 1 further comprising a crank coupled to said first jack body, said crank configured to adjust an elevation of said caster with respect to said carriage frame. 5. A carriage assembly in accordance with claim 1 the scaffold further comprising at least one scaffolding member coupled to said carriage frame. 6. A carriage assembly comprising: a scaffold;a carriage frame for supporting the scaffold, the carriage frame consisting of four tubular frame members, wherein the tubular frame members are arranged and connected at their terminal ends such that they form a rectangular frame, wherein each end of each of the frame members has an open port for receiving a jack body, such that each corner of the rectangular frame consists of a first port oriented in a first direction and a second port oriented in a second direction substantially perpendicular to the first direction, a first of the frame members having a first axis, and a second of the frame members having a second axis that is substantially perpendicular to the first axis, wherein the second frame member is directly coupled to said first frame member, and wherein the open ports each have a substantially similar configuration;a caster; anda first jack body coupled to said first frame member and said caster, said first jack body having a longitudinal axis that is substantially perpendicular to the first axis, said first jack body configured to selectively move said caster with respect to said carriage frame along the longitudinal axis to enable a height of said carriage assembly to be selectively adjusted, wherein said first jack body is interchangeably coupleable to the port of said first frame member and to the port of said second frame member to enable a length of said carriage assembly and a width of said carriage assembly, respectively, to be selectively adjusted without requiring the scaffold to be disassembled from the carriage frame. 7. A carriage assembly in accordance with claim 6 further comprising a second jack body coupled to said second frame member such that said second jack body is movable along the second axis. 8. A carriage assembly in accordance with claim 6 further comprising a crank coupled to said first jack body, said crank configured to adjust an elevation of said caster with respect to said carriage frame. 9. A carriage assembly in accordance with claim 6 the scaffold further comprising at least one scaffolding member coupled to said first frame member. 10. A carriage assembly comprising: a scaffold;a carriage frame for supporting the scaffold, the carriage frame consisting of four tubular frame members, wherein the tubular frame members are arranged and connected at their terminal ends such that they form a rectangular frame, wherein each end of each of the frame members has a receiver opening for receiving a jack body, such that each corner of the rectangular frame consists of a first receiver opening oriented in a first direction and a second receiver opening oriented in a second direction substantially perpendicular to the first direction, wherein each of the receiver openings have a substantially similar configuration, a first of the frame members having a first axis, and a second of the frame members having a second axis that is substantially perpendicular to the first axis, wherein the second frame member is directly coupled to said first frame member; anda first jack assembly that comprises a jack attachment member sized to interchangeably fit within the first receiver opening and within the second receiver opening such that said first jack assembly is movable along the first axis and along the second axis, respectively, a jack body coupled to said jack attachment member, and a foot comprising a caster and a shaft extending from said caster, said jack body defining a jack opening, said jack body having a longitudinal axis, said shaft sized to fit within the jack opening, said first jack body configured to selectively move said caster with respect to said carriage frame along the longitudinal axis, wherein said first jack assembly is interchangeably coupleable to said first receiver opening and to said second receiver opening to enable a length of said carriage assembly and a width of said carriage assembly, respectively, to be selectively adjusted without requiring the scaffold to be disassembled from the carriage frame. 11. A carriage assembly in accordance with claim 10, wherein the first receiver opening is polygonal in shape. 12. A carriage assembly in accordance with claim 10, wherein at least one of said first frame member and said second frame member is fabricated from a metal material. 13. A carriage assembly in accordance with claim 10, wherein said first jack assembly further comprises an adjustment mechanism configured to move said foot along the longitudinal axis. 14. A carriage assembly in accordance with claim 13, wherein said adjustment mechanism comprises a crank. 15. A carriage assembly in accordance with claim 10 further comprising a retaining pin, wherein said jack attachment member, said first frame member, and said second frame member each includes an opening sized to receive said retaining pin. 16. A carriage assembly in accordance with claim 10 the scaffold further comprising at least one vertical scaffolding member defining a scaffolding opening, wherein said carriage assembly further comprises at least one vertical attachment member sized to fit within the scaffolding opening, said vertical attachment member coupled to at least one of said first frame member and said second frame member. 17. A carriage assembly in accordance with claim 16 further comprising at least one horizontal scaffolding member coupled to said vertical scaffolding member. 18. A carriage assembly in accordance with claim 10 further comprising a second jack assembly movable along the second axis.
