Basement framing is a large portion of the projects we do and we're very proficient at it.
There are certain things that need to be taken into account when framing a basement such as: headroom, plumbing layout, egress windows, fire/draft-stop and soffit around pipes/HVAC.
Although it's not required we always build our walls using a 16" on center layout.
Basement walls will typically need to be 'Floating' to acommodate the expansive soils found in Colorado.
If the concrete slab heaves the 'Float' will act as a buffer keeping the walls from pushing up the floor above.
Basement floors that are wood or structural suspended concrete won't need to be floated.
