1 WTC's 20-story base gets new glass design

A new plan to clad the base of 1 World Trade Center in glass was approved Tuesday by the building's owner, the Port Authority of New York and New Jersey, after technical problems forced the redesign of a previous scheme earlier this year.



Crain's reported this month that the Port Authority had reached a new design after the plan to enclose the 185-foot-tall concrete base in prismatic glass panels designed to reflect light were too difficult to make and shattered easily.



The Port Authority's board authorized $37.2 million towards project and contract costs. Permasteelisa North American Corp. will engineer, fabricate and install the new facade, which will consist of stainless steel slat panels around the building's concrete base, covered with glass fins. The glass fins will reflect light during the day, giving the building's base a distinctive look, the Port Authority said.
