Lots of people have heard of the Horton Grand Hotel in downtown San Diego, CA. Here's a view of the hotel that not too many people see - a view from the roof of this historic building. 

ISE was involved in a forensic case that required us to do some work on top of the hotel. The view is a panoramic one close to sunset looking towards the west towards Seaport Village and the convention center.

Featured Video Clip (Concrete Fail)

ISE performing load testing of concrete test specimens to determine its axial compressive failure characteristics.

In this example, you can see quite dramatically how concrete fails under a compressive load. Once the ultimate stress is reached, the load carrying capacity of the material rapidly drops off producing the fracturing seen in the video.
