Landscape design application/Software in Bentley.

Hi All

Is there any good 3D landscape design softwares for Microstation? Love to find some that can help me to blend objects as "Road/Pathway/squares/straircases/Sustwalls etc and parks/Plants etc etc in 3D, and get the design result so you can send it to 3d/GPS excavator,tachymeters etc etc.
