I posted a quote in the "WTC7" thread on critics corner and it is being totally ignored by Alec.

BEFORE it moves into a new office tower in downtown Manhattan, Salomon Brothers, the brokerage firm, intends to spend nearly two years and more than $200 million cutting out floors, adding elevators, reinforcing steel girders, upgrading power supplies and making other improvements in its million square feet of space.
The work, which began last month at Seven World Trade Center, reflects both the adaptability of steel-framed towers and the extraordinary importance of fail-safe computer and telephone systems for the brokerage industry. According to many real estate experts, no company has ever made such extensive alterations to a new office building in Manhattan.
Much of the new electrical, air-conditioning and mechanical equipment will serve three double-height trading floors. To create the extra height, workers are removing most of three existing floors, using jackhammers to demolish concrete slabs and torches to remove steel decking and girders beneath the concrete.
After the girders are cut into sections small enough to fit into a construction elevator they will be sold as scrap for about 4 cents a pound.
In some office buildings, that alteration would be impossible, but Silverstein Properties tried to second-guess the needs of potential tenants when it designed Seven World Trade Center as a speculative project.
''We built in enough redundancy to allow entire portions of floors to be removed without affecting the building's structural integrity, on the assumption that someone might need double-height floors,'' said Larry Silverstein, president of the company. ''Sure enough, Salomon had that need.
''And there were many other ways that we designed as much adaptability as possible into the building because we knew that flexible layout is important to large space users.''
