Red Faction Guerrilla - rebuild/reset all buildings?

In Red Faction Guerrilla, I see that the more buildings I destroy, the more size the save file increases, that means (I think) the save file actually stores which buildings get destroyed. I have completed the game but I don't see the buildings rebuild. So does anyone know how to rebuild the building? (I'm thinking about using a save file editor to remove the destroyed buildings that get stored).

What I want is full map, full weapon, full buildings (and bridges).

What I want is full map, full weapon, full buildings (and bridges).

Easy. Step 1: Download Mod Manager by HazardX

Step 2: Read the readme file of Mod Manager, then just copy the content of Mod Manager into the game's folder

Step 3: Run ModManager.exe (which you just copied in step 2), then select the mods (Freeroam Mode: give you full map & Free Upgrades: give you full weapon), then click "Activate Mods".

Step 4: Run game & start new game (give you full buildings and bridges), then save game.

From now on, just run the game & you get: full map, full weapon, full buildings (and bridges).

Enjoy!
