All depends on how you measure it.

What we do as architects is not always fun, but even some of those "not so fun" items can be satisfying.   I like to paint and my rationale is that I can see my progress.  As an architect I have been hired to do a few "as-built" drawings because there were no existing plans.   While I have to get my self in the right frame of mind to go measure, I get a great deal of satisfaction when I draw up a plan from my measurements and the pieces just come together.  Again I think it is that visual satisfaction of seeing all the pieces of the puzzle coming together is what satisfies my soul.  I get the same satisfaction when designing.  When I am near the end and all the spaces just flow, it is just a good feeling.  I don't know about most architects, but I tell people when I have worked out a good plan I know it is right because I can "feel it".  

This current project is in downtown Durham, NC.  There was a fire on the third floor.  The owner needs as-built plans in order to provide new construction documents for the new HVAC. 

There are challenges when measuring an old building as you never know what the wall thickness are and they can change from floor to floor.  You spend a little time scratching your head trying to figure out why the inside face of exterior walls aren't the same dimension on each floor.  I like to try to establish a perimeter and then work my way into the building.  That doesn't work so well when the wall thickness changes and you can't see it.  

I get a great deal of satisfaction when working from one end of the building to the center and then taking measurements of the opposite side and when they meet in the meeting I am only off by 1 1/2" over a 100' long building.  I pad myself on the back and think I must have done something right!  Not the most desirable thing I do, but with my MP3 player, tape measure, and laser measure I am off in my own world.  You learn over the years there is no reason to rush.  You also learn you never get it all the first time either!
