At First Glance

One of the things I quickly learned in the field is that not everything is what it appears to be.  Whether it is an epoxied anchor bolt that you can pull out by hand or a hurricane clip wedged between two pieces of wood with no nails, the closer you get to see and touch the structure the more confident you will be with your field observation.  The girder truss in the above picture looks to be properly supported.  A stud pack below the truss and hurricane clips on each side of the truss are standard fare in a region with a low wind design speed.   If I stood across the room and looked up at this condition, I would feel satisfied.  Walking further into the structure, however, I saw that the stud pack may not be adequate.   Have a look at the picture below.  

When observing the framing in apartment complexes or housing units, the framing quickly becomes redundant.  Continuing to walk through each room in each unit is still important to not miss the problem conditions that exist isolated to specific units.
