Divide a splitted surface

I need to design a facade that is composed of perforated metallic panels, each panel´s dimension is 1.02 x 2.34 m. I have manage to divide the surface in these dimensions, but after splitting the surface I can not divide the subsurfaces. Every time I connect the divide surface component the points appear all over the original surface instead of the new subsurfaces. I have been trying to fix this definition for several days and haven´t found the solution. Please help me with a suggestion on how to keep going so I can proceed with the definition and start working with the attractors to obtain perforated surfaces. 

I attach the files in which I have been working and and image of a reference.
