Organizing Game Models

Hey Guys,
I’m about to start a game project and I need an easy way to both plan what 3D models I need, and then organize them once they are completed.
I was thinking I could do a spreadsheet, but I wanted it to be easily organized, so I can easily pull up all the models I need for one map, or all the different types of walls.

I guess my question is: what do you guys use/suggest to organize models for projects?
