1. A method for manufacturing a wind turbine, the method comprising:
a) manufacturing a bottom module, the bottom module comprising at least one first platform and two or more vertical legs that are connected together by a first horizontal connection and are located radially outward of the at least one first platform;
b) manufacturing a top module separate from the manufacturing of the bottom module, the top module comprising at least one second platform and two or more vertical legs that are connected together by a second horizontal connection; and
c) assembling the bottom module and the top module to form a platform assembly, wherein the two or more legs of the top module are separate from the two or more vertical legs of the bottom module;
wherein the bottom module and the top module are assembled by aligning and connecting the bottom module with the top module by aligning and connecting the two or more vertical legs of the bottom module with the two or more vertical legs of the top module radially outward of the last one first platform of the bottom module;
wherein the top module includes a plurality of horizontal struts connecting the two or more vertical legs of the top module together, the two or more vertical legs of the top module and/or the two or more vertical legs of the bottom module including backing plates, further wherein the two or more vertical legs of the top module are aligned and connected to the two or more vertical legs of the bottom module using the backing plates.
