My experience with the building layout vignette was little better than my interior layout experience. I think I made errors that could lead to failure. In short I think I had too many doors leading off of a lobby and the rooms may have been too small.
If you haven’t read the previous two posts about my interior layout, then do that. It all started with a very poor performance in the Interior Layout problem. It was very difficult for me to concentrate after blowing the Interior Layout. I really wanted to get up and walk out. I tried to keep a level head. I thought if there is no hope of passing, I can still learn something from the Building Layout problem.
So I start with the building layout. Shift, nugde pull. I got all of the relationships. I got all of the windows, direct access connections, doors and swings. I placed the entry at the right street. I placed rooms to get the view as required. I even shifted two rooms between the first and second floors. The program didn’t state a specific floor location for those rooms. All of these things I did, I think were ok. Still I don’t think it was a pass.
When you draw rooms with the NCARB program, it draws from the centerline of the wall. Not from the interior wall surface. I knew this and overall chose to ignore it. I’m having a hard time remembering if I adjusted my corridors to have the minimum clearance. I just can’t remember, but if I didn’t adjust them I failed. My corridors would have been 4 inches short of the minimum code required clearance. Even if I failed, I hope I made this adjustment. I think I did make this adjustment during the exam. But I did not check my rooms, so many of them would be shy of the required square footage.
Let me restate that because the last paragraph is caught up in failure.
The program gives you the distance (and area) from the centerline of the wall, not the interior face of the wall. The program is grading the area from the interior face of the walls. So if a rectangular room is drawn the software prompt says 8′ wide (by 25′ long and 200 sq. ft.), but it is actually 7′-8″ wide (by 24′-8″ long and less than 200 sq. ft. from the interior faces). Do you get it?
Make sure you do. Practice.
I hope I adjusted my corridor. Right now I want to fail for another reason. Rooms that are too small and a lobby with too many doors will probably tank my building layout. Oh well. It is time to move on to Building Design and Construction Systems.
