Well many people argue about the fact of the old and new plans. Some people don't really like the new concept of the WTC, but some do, and as you can see there would always be conflict which is normal for any project, but you do see a lot of differences in the old and the new WTC. This is the reason for most of the conflicts that are going on. It also would include the design and engineering differences.
