just like anything else. Below is sample that would prolly work for tfc but you will need to find a valid classname for nsp or whatnot. also you may have to make a copy of barney.mdl from the valve models dir to the nsp side. also depening on what classname you use he might be not solid, ie you can walk through him...

 
 [strip]
 
 [add]
 PRECACHE_MODEL(models/barney.mdl)
 
 {
 	netname/barney
 	classname/item_tfgoal
 	origin/-610 -2609 -685
 	model/models/barney.mdl
 	owned_by/0
 	message/Hi I'm Barney!
 }

Here is some actual code I use to have beer cans strewn about in the map 2fort under TFC.

 PRECACHE_MODEL(models/beer1.mdl)
 
 // BEER CANS BLUE BASEMENT
 {
 	netname/stripper2
 	classname/info_tfgoal
 	origin/-590 -2550 -665
 	model/models/beer1.mdl
 	angle/180
 }
