Create Three Terrain Models Three Sites which are Geographically Separated

Question

Situation: 
 One Survey CADD file. One Field Book. Two Data Files. Three geographically separated sites. [See the image below.] 
 
 I want to make three Terrain Models from the survey data. 
 Should I put a boundary around each of these sites then go to Terrain Modeling Graphical Filter tools? How do I create a boundary for each separate site (quickly)? Not sure what is the best workflow at this point.

Could you not just reference the relevant data into separate files i.e. one of CADD data, one for field book, one for data files, and then create a terrain in each file using a terrain filter? Or just manually select the data for each terrain (if it is all in one file) - slower method as you would have to select break lines, then spots etc?

Mark, 
 Thanks for your input. What I did was separate the data into three separate CADD files. Cleaned up the survey points and linear features as if each CADD file represented a single isolated survey. Then created terrain Models. Then cleaned up crossing break lines and so on and so on... 
 Actually, I made this more complex than it was. I was looking for some "magic" boundary tool... then create three terrain models within the same file. 
 Thanks again.
