Answering the following:

1. What should/could the Structural Engineer have done when turned down by the Owner to evacuate the building?

2. How could there have been more coordination between the engineering design and the construction of the building to identify inconsistencies between the design elements and the actual construction?

3. What/How can the design engineer protect him or herself from changes to the building for which he/she is not made aware and that could impact the structural design ?
