How should I build these steps?

[Bartwood]

I have been trying to build these steps with the slab tool but its not working very well. Anyone have any sugestions. Should I be using break walls for the timber risers and sides?
I have a picture of the origional and a shot of my terrain where I want to build them.

Thanks
Paul
