I wander if they a following there own building code this time. they said the other to were not built to code because the city of New York own them and did not have to follow there own code. Had they they might still be standing.
When the Twin Towers were constructed in the 1970s, the builders were granted some exemptions from New York's building codes. The exemptions allowed the builders to use lightweight materials so the skyscrapers could achieve greater heights. But, the consequences were devastating. According to Charles Harris, author of Engineering Ethics: Concepts and Cases (compare prices), fewer people would have died on September 11, 2001 if the Twin Towers had used the type of fireproofing required by older building codes.
